White yam is good.

White yam contains mucilage proteins, these mucilage contains more hemicellulose that can be dissolved in water, and after absorbing water, it can be swollen by 80 to 100 times, which can easily produce a sense of satiety, thus enabling us to avoid consuming too many calories, and it is also rich in amylase, dietary fiber, vitamins and trace elements.

White yam planting method:

1, variety selection

Choose the small white mouth seedling that is free of disease, frost, and mutation.

2, germination

After the hibernation festival, the seed potato will be cut, sterilized, disinfected, dried and germinated.

3, fertilization

Apply 150 kg of diamine/mu, 100 kg of potassium sulfate fertilizer/mu, and 3-4 squares of rotted organic fertilizer per acre on the cultivated land.

4, tuber selection

Select no disease spots, no rot, smooth tubers, cut into 6-10cm long, each tuber should be with the top bud. The selected seed potatoes need to be sterilized, ventilated and dried, and planted after the wounds have healed.

5, seedling

From the end of March to the beginning of April in the greenhouse row seedling, North China seedling transplantation is generally planted in mid- to late-April, direct planting of the ground is not frozen, planting the earlier the better, the planting planting before the bottom of the soil moisture must be guaranteed sufficient, planting planting no longer watering to promote the root of the yam seedling rooting down.

6, fertilizer

The whole life cycle needs to be fertilized 2-3 times. When the seedling up to about 10 cm, combined with the mid-plow weeding for the first fertilizer, generally 20 kg of urea per mu. From August to mid-September is an important period of potato growth and expansion, generally 10 kg of potash per mu sprinkled in the root cracks, irrigation once. At the same time, in the afternoon on sunny days every 10 days foliar spraying of potassium dihydrogen phosphate 1 time, *** spray 3 times.
