yam

There are Dioscorea genus Dioscorea 1, about 80 kinds.

From shanxi pingyao, jiexiu, distribution in China's north, northwest and the Yangtze river basin in jiangxi, hunan and other regions.

Plant said yam, wild sweet potato said wild yam; Traditional Chinese medicine said yam, yam, yam, etc.

Because of its rich nutrition, since ancient times has been touted as a cheap and fine tonify deficiency, both as a staple food, and for vegetables, also can be made into sugar-coated berry, such as snacks.

China's agriculture is in the north of henan province, shandong, hebei, shanxi and central south, southwest and other regions are cultivated. Stem leaves wither in winter after excavation of, cut hair, rinse and dry.

China's cultivation of yam are mainly two types: ordinary potato yam hotan. Common yam tuber is lesser, notably the ancient HuaiQingFu (now in henan jiaozuo, including cause, fraternity, QinYang, Wu Zhi, county, county) produced by yam rare, xi said "huaiqing yam", known as the "pregnant" for the nation.

Now there are three parts of the country yam has applied for the national geographical indications protection products, is a kind of "iron yam" its produced in henan jiaozuo county, cause, etc; One is "Chen set yam" its produced in heze city of shandong province Chen town, including "rough yam skin" and "xi shi seeds yam"; A kind of "bergamot yam", origin of hubei Wu Xue. In addition, ruichang city in jiangxi province nanyang town of yam has recently applied for a national geographical indication protection products. In addition, jiangxi province nancheng as jiangxi province's largest yam cultivation base, one of three big yam production base in China, in 2011, approved by national ministry of agriculture, allow registration of geographical indications of agricultural products, the implementation of protection.

Artificial cultivation

Planting base

Four huaiqing Chinese medicines are ancient HuaiQingFu area around (now QinYang and jiaozuo in henan province) of yam, twotooth achyranthes root, radix rehmanniae, chrysanthemum, such as the four traditional Chinese medicine (TCM), but the iron yam is the highest grade in Chinese yam, county in the south of the Yellow River, north river dawen, only county unique geographical location and climate can produce iron yam.

: define 】 【 iron yam is a kind of huaiqing yam, its producing is county, in the core regions near river dawen clay zone, this is determined by the soil. County is located in the Yellow River and river dawen envelope upstream of the sea area, and the Yellow River, the mother river dawen originated in the taihang mountains water moistens the land together, surrounded on three sides by mountains, one facing the water surface of advantaged natural conditions. County land is divided into near the Yellow River and near the river dawen sand clay sandy soil, the dividing line in this shop - roughly the canal river - peony zhang - xu lu village, north river dawen clay, south of Yellow River sand. According to the local yam growers experience, more suitable for planting Chinese yam river dawen clay.

Cultivation techniques

"Variety"

At present the main planting of piled long yam yam varieties, at "daiwa taro" yam yam and Japan and other varieties, domestic Chen set yam yam shandong heze and henan jiaozuo area iron yam more famous. Fine wool yam and at yam are common yam long column variants. Japan yam is a strong adaptability, good quality, strong disease resistance, high yield, promising varieties.

"Choose to ditch the whole strip"

Yam cultivation should try to avoid the continuous cropping, general rotation once every three years, and avoid the kind of peanut, red taro. To choose for the loose soil deep, fertile land, requirements of soil is consistent, the layer has a heavy soil, soil and white sand hills, groove should be destroyed completely, at least 1 ~ 1.2 meters of the soil is clay, sand soil intercalation, etc. Otherwise it will affect the appearance of the tuber, also has an effect on quality. Soil with neutral advisable, trenching at present commonly used mechanical trenching. Yam cultivation in north and south direction advisable, can adopt double row planting or single planting (according to individual plots need things grow when you can take a wider spacing), double row planting, big row spacing of 1.7 ~ 1.7 meters, small spacing (groove spacing of two yam) 40 centimeters, planting distance in 20 ~ 25 cm, groove depth of 85 ~ 100 centimeters, groove width 70 cm. When the whole field leveling, prevention of watering pouring uneven. Need to get drainage design, ensure that the field QiNa without water. Single row planting in 80 ~ 100 centimeters, the spacing groove 30 cm wide, groove depth of 90 ~ 90 centimeters, planting distance of 20 ~ 25 cm.

【 suitable sowing 】

Greenhouses yam is generally around New Year's day started planting, generally require the surface 5 cm ground temperature stability more than 9 ~ 10 ℃. The yam before planting seedlings to dry, it can activate kind of potato, can have the effect of sterilization, high budding rate again. If made kinds of potato yam tuber cutting, can be in touch with lime powder in the slit, disinfection effect. When seeding to do have a bud, the size of a piece of, that shoots out of qi, in addition, with 500 times of carbendazim, powder rust ning 1000 times, 1000 times 72% chlorothalonil seed 3 ~ 5 minutes, after dry, sowing seeds in the soil before sowing surface spraying high lipid membrane.

Yam with organic fertilizer (such as rotten cake fertilizer, chicken manure, YaFen or human and animal dung, etc.), inorganic fertilizer is complementary, amount to 2000 ~ 4000 kg per acre general, plus high potassium compound fertilizer 40 ~ 60 kg, or use the yam special biological organic fertilizer 200 ~ 300 kg, and soil mixing fully, in case burn seedlings.

The field management 】

1. Light fertilizer. If the basal applying more fertilizer little or no fertilizer, in order to ensure the yam high-yield, topdressing commonly 2 ~ 3 times, on the ground when the plants grow to about 1 meter in a higher topdressing nitrogen compound fertilizer, topdressing at intervals of about a week after the time, three times. Yam) phase is given priority to with phosphorus, potassium content is higher the multielement compound fertilizer (yam demand for nitrogen, phosphorus and potassium ratio is 1.5:2:5), 30 kilograms per mu, the best method to rush. At later growth stage can be spraying on the leaf of 0.2% potassium dihydrogen phosphate and 1% urea, prevent premature aging. Especially it is important to note that the absorption of yam shallow root system distribution, occurred earlier, in horizontal direction, fertilizer should be applied into the shallow soil layer for yam root absorption.

2. To prison. ChaJia and weeding yam on sowing back cover 6 ~ 10 cm aggradation, after pouring with "dedicated herbicide yam" 150 ~ 200 grams of 100 kg of water spray evenly, cover film, in a timely manner after emergence step-stone, stand at about 2 meters high, positive show "people" word, lateral oblique crossing, every 7 ~ 8 meters with thick bamboo or rods reinforcement, anyhow must take a firm, in case of flopping.

3. Qiao watering. Yam also shoulds not be too afraid of waterlogging drought, if too dry will seriously affect the yam enlargement, particularly in the tuber expansion period, time about in the middle of April until late may, during the pouring a permeable in about 10 days, in late may after watering according to soil moisture water properly.

4. Pest control to keep up. Plant diseases and insect pests on the pathogenesis of continuous cropping plot is heavier, the first year of planting plots with light, after the yam tendril shelves, began to prevention and control of spraying.

Yam for anthrax, the main disease belong to fungal diseases, common people say defoliate disease, early performance leaves yellow, the leaves appear small spots, finally the stem dead leaves fall, the disease case is given priority to, make rotation alternate husbandry, choose no disease to plant potatoes, with 25% carbendazim powder 500 times before sowing seed potato disinfection 25 to 30 minutes, after cultivation to strengthen field management, enhance plant disease resistance.

Generally can be used in the early onset of 70% mancozeb 500 ~ 600 times liquid, 50% mildothane 700 ~ 800 times liquid spray alternately, the onset of heavy when available Japan "and taro" yam special formulation of pesticide, the early onset of every 7 to 10 days to spray, continuous spraying commonly 2 ~ 3 times.

"In a timely manner to harvest"

Normal outdoor yam's harvest is very long, from August 20 to 4.5 in the second month, yam in underground does not rot, not bad, generally concentrated to harvest before and after the frost, for the Spring Festival market. But shed yam is different, because the harvest time on June 20, yam starch content itself is little, high water content, so there is no resistance to long time storage, greenhouses yam should be timely sales after harvest. In addition, due to factors such as plant size, greenhouses yam use artificial excavation of more now, because of yam skin is very thin, to prevent mechanical damage when digging yam, yam with mud foreskin stacked, for sales.

【 or 】

The first: it is appropriate in den tube growth. In addition to the cavernous cultivation, fertilization or yam

yam

Use of rotten organic fertilizer, all of them, and can improve the yield and quality of yam. Organic fertilizer could improve soil composition, provide adequate nutrition, extend the period of the release of nutrients and utilization, improve root respiration, and provide sufficient moisture. Leaves began to sprout from fresh yam plant, its nutrients from potato, into the development of the early Chinese yam need more nitrogen fertilizer, so as to promote its growth, formation, potato piece to start potash is particularly important. Yam seemed easy absorption of phosphorus from the soil, in addition, if can add magnesium fertilizer, can also help the yield increase.

The second: yam cultivation, must choose fertile soil, soil deep, strong retention of fertility, good air permeability, convenient irrigation and drainage of sandy soil commune 35 ~ 45 centimeters, the commune land, to the above 20 ~ 30 centimeters of topsoil in one side, continue to the commune and 35 ~ 45 cm, avoid by all means double layers. Developed the cultivated land after the commune, ditch, basal can be applied into the cultivation of a ditch. Basal general mu shi superphosphate 20 kg, 3000 kg rotten organic fertilizer, plant ash 200 ~ 300 kg. Fertilization when planting groove of first fill in the original surface of topsoil, thickness is 15 cm, then basal on the soil layer, and then covering 15 cm.

Yam fertilizer mainly in the mid-late growth, early need less fat. Yam emergence and tidy after 1 20% human waste fertilizer, after once every 20 ~ 30 days. Fertilization can be in 30 centimeters from plant 1 article 6 ~ 10 cm deep fertilization ditch, mu shi faecal matter 700 ~ 1000 kg. Underground tubers into vigorous growth stage, should return 1 fertilizer. Mu fertilizer 20 ~ 30 kg, 40 ~ 60 kg hole applying cake fertilizer or furrow, turns the soil after fertilization, in order to ensure the tuber elongation and swelled with plenty of nutrients. According to the condition of plant growth to determine whether additional fertilizer in the future.

Processing and storage

Processing method

Will dig up the wool yam 】 【 top reed head cut off by the yam rhizome (reserved for use), sediment, water wash away all fibrous root, scrape the skin, soaked with water for 24 hours, and then wash gluten, then take out to dry the surface moisture, add sulfur smoked to contained in the deeply heart (usually every 100 kg of fresh yam with sulfur 0.4 ~ 0.5 kg), reoccupy clear water wash, lay in the sun exposure to the skin is a bit hard into the crate pile frowsty, prompting its internal moisture spillover, accelerate the drying, and prevent dry wet. Frowsty again after drying, so repeatedly, until the internal dry (such as in rainy weather, the oven can be put in use charcoal fire drying). The goods in the coarse, color white, foot powder, pest-free mould for quality.

Of wool yam yam light 】 【 are selected, in addition to a small individual, loaded into the basket, add sulfur tank with a little sulfur smoked once again. Then put the wool yam in the tank, the water immersion (the surface of the water flooded yam) 1 ~ 2 days, and soak through the heart as well. Rinse off with clear water then skins, appear on bamboo mat air to surface frost, dry wet moderate, soft hard to rub when appropriate. Specific operation is put in flat table mat a surface plane very smooth piece of wood, wool yam on board, with another piece of the same smooth surface on the board down, hold in rub your back and forth, until the round straight solid roots. Each rub one drying after 1 hour, and then into the cylinder cover 1 day, with white cloth and rub. So repeatedly, until

. Dry for a quick light yam 】 【 goods with dry feet, color white, cylindrical, flat on both ends, 9 ~ 18 cm long, 1.5 ~ 3 cm in diameter, thickness uniformity, straight, smooth, powder sufficient for quality.

Light export yam 】 【 yam exported to southeast Asia countries, export before the need to further processing and special packaging. The method is: put after rub yam rhizome of light in a little submerged in water, after waiting for surface wet article with thin sheet metal or glass blowing, make whole yam into cylindrical, up and down the same size, then the surface with a copper mesh or emery cloth smooth, make its skin is powder, with white cloth wipe skin powder, finally to wood file at both ends, smooth foot put on bamboo sun to dry.

Storage method

As containing more amount of mucus and starch, if be affected with damp be affected with damp is easy to become soft and sticky, two weeks will be moldy, though become yellow, and the most easily, therefore in the process of storage should be to prevent moisture intrusion. The specific method is: should be packed in wooden cases, with kraft paper in the bedding, corner line with shavings or wood wool, and then the yam neatly into, above the same cover paper, nail box sealed, placed in ventilation, cool, dry place. The storage place should be slightly higher, piled up off the wall, and ventilated breathe freely. Before the rainy season, should be out of the exposure, and sulfur smoked a, smoked again in the summer. So you can secure the summer; Late spring to early fall, should check once each week. If discover slight mildew spot, can stand in the sun drying, reoccupy brushes, gauze or file to remove mildew spot, and then to mount of powder mixing, drying (if the sun is too strong, can cover on yam tissue paper, in order to avoid the sun crack yellow).

First, long-term preservation

Yam at 0 to 4 degrees can be stored for 3 years. If the temperature of 37 degrees, can save about 10 days, cooked along while, yam emergence to dying frozen, yam root - 10 degrees. If need to save for a long time, it should put yam in wood sawdust embedding, wrapping them in short time saved can be used in cold dark. If buy, is cut yam, avoid contact with air, wrapped in plastic bags, into the refrigerator cold storage as appropriate. Shredded yam also could freeze in the fridge.

Second, the short-term preservation

In order to ensure the yam quality, if you don't eat immediately after purchase please yam properly handle, and save:

1. Yam peel after cutting in accordance with the time consumption in plastic bag packing, and the fridge upper quick-freeze immediately.

2. Don't need thaw when cook, initiate immediately after the water to boil the pot, convenient and ensures that the yam quality.

3. Chinese yam and apple because is rich in iron, brown after cut into a normal phenomenon, can be at ease to eat.

The general principles of the three, saved

Yam preservation and potatoes, sweet potatoes are similar, placed in ventilated, shady and cool place. Fresh yam easy oxidation with oxygen in the air, can also contact with iron or metal forming Browning phenomenon, so cut yam had better use bamboo knife or plastic blade, after first draw a line in the skin, reoccupy hand peel away into a paragraph. Incision easy oxidation, can use first rice wine a dip, and then blow dry with blower, prompting wound healing, and then wrapped in a napkin, outer package several layers of newspapers, in a cool, can be in the corner.

How to choose and buy

Winter to eat again, many people will be yam on the table, please. Fine yam, white meat, it is released by the national ministry of health of both food and vegetables. Chinese medicine will yam medicine cure very early, and has a reputation as a medicine in the top grade. So how to choose to good yam?

1. The first phase modulation weight, yam with the same size, the heavier is better.

2. The second whiskers, the same variety of yam, whiskers, the more the better. Whiskers the yam taste more surface, yam polysaccharide containing more and better nutrition.

3. Finally look at transverse section, the flesh yam of this should is snow-white, suggesting that are fresh, if yellow rust do not buy.

Note: if you have any abnormal surface spots yam is absolutely can't buy, because it might have been infected with disease. Should also note yam section with mucus, skin without damage. Buy yam yam afraid, afraid of cold hot, winter, usable hand grip it about 10 minutes, Chinese yam is sweating with the cold. Break, frozen yam cross-sectional mucus will turn into water, and have a hard heart red color, quality is poor.
