Yam planting method, fertilizer-loving, full base fertilizer, early topdressing.

Yam, eaten by human beings since ancient times, is one of the earliest plants eaten by human beings. Yam tuber is thick and juicy, sweet and soft, and sticky. Both raw and hot food are delicious. So do you know how yam is cultivated? Is there any good method in the process of feeding? What matters should be paid attention to in yam breeding? Dear friends, come and have a look.

Cultivation method of Chinese yam (basic knowledge): the best breeding time: Chinese yam should be planted before and after Qingming, not too early, and the most suitable temperature is 13℃.

The best growing soil: loose and fertile sandy loam with good drainage and clay without stagnant water, which is loose and dense, with good quality, but low yield, and is suitable for planting.

Requirements for growth humidity: Before sowing yam, water the bottom, and prepare the soil for border cultivation. Most of them are ridge farming, and the ridge width is 120 cm. The ditch between two ridges is used for drainage and irrigation. Keep the air moist.

Optimum growth temperature: the requirements for climatic conditions are not high, but a warm and humid climate is better. The aboveground part will die after frost, and the underground part is not frost-resistant, and the growth temperature is 20 ~ 30℃.

Optimum growth light: the production environment of yam does not need high light. Yam is a short-day crop. Before and after the solar term every year (usually after July 20), the sunshine becomes shorter, which is most conducive to the expansion of yam.

Matters needing attention in yam culture: Fertilization: If you like fertilization, you should apply sole fertilizer and topdressing in advance. If the topdressing is late and the seedlings grow slowly, topdressing is generally not less than 2 ~ 3 times. For the first time, strip application was carried out in the middle and late June, with about 1500 ~ 2000 kg of human manure or 50 ~ 75 kg of cake fertilizer per mu; The second time, from the end of July to the beginning of August, 2000 ~ 2500 kg of human manure, urine or manure was applied to the roots.

Key points of watering: Chinese yam is drought-resistant and waterlogged-resistant, and the suitable soil water content is 18 {BF}. If the water content is too high, or it rains for several days in a row, the accumulated water in the yam ditch can't be discharged in time, which will cause the humidity of the yam land to be too high, and it is easy for the yam to be infected and rotted.

Breeding points: Yam mainly depends on reed heads and small bulbs.

Reproduction of reed head: Dig out the root in June+10, 5438, choose yam reed head with short neck, full bud head and no diseases and insect pests, fold it 16 ~ 20 cm, sun it for 2 ~ 3 days, and dig a pit indoors or outdoors, the depth of the pit and the thickness of the cover shall be subject to prevent the reed head from freezing.

Propagation of beads: The shoots (yam bean) turned yellow in June of 5438+ 10, and were stored in dry sand outdoors. Take it out in the middle and late March in spring and sow it in the sun. Row spacing is 20 ~ 26 cm, plant spacing 10 cm, ditch depth is 6 cm, 2 ~ 3 yam bean seeds are planted, and the soil is 6 cm. Emerge after half a month, dig out and plant in autumn.

Pest control: anthrax, clearing fields after harvest and burning fallen leaves. When planting, soak the roots with 1: 1: 150 wave water for 10 minute, and produce or spray 800 ~ 65438 fungicides with 65 {BF} zineb 500 times or 50 {BF}. Brown spot disease, crop rotation, clean countryside. Spraying 500 times of 65 {BF} zineb or 200 times of 50 {BF} dinitrate powder for 7 days 1 time, and continuing to fight for 2-3 times.

Experience of breeding yam: When breeding yam, we should pay attention to timely watering, fertilization, growth temperature and light, and also pay attention to the prevention and control of pests and diseases. Yam tuber is very sensitive to potassium fertilizer. Spraying liquid fertilizer containing various trace elements at each growth stage will not only make the branches and leaves flourish, reduce diseases, but also significantly increase the yield. Through the above explanation, I believe you are no stranger to "what are the requirements of yam for the growth environment". When planting, according to the demand of yam for natural environment, cultivate and plant yam according to local conditions, and do a good job in field management. I'm sure the yam you planted will be harvested.
