Characteristic agricultural ecological agriculture, leisure agriculture and other terms also continue to emerge. The following editor will introduce the planting technology of White Yam.

The main results are as follows: (1) No disease, no freezing injury and no variation of small white mouth seedlings are selected.

(2) slicing, disinfecting, sterilizing, drying and sprouting seed potatoes after the stinging festival.

(3) 150 jin / mu of diamine, 100 jin / mu of potassium sulfate and 3 to 4 square meters of mature organic fertilizer will be applied to the cultivated land.

(4) No disease spot, no rot, smooth tuber should be selected, cut into 6-10cm length, and each tuber should have terminal bud. The selected seed potatoes need to be disinfected, ventilated and dried, and planted after the wound heals.

(5) planting and raising seedlings in the greenhouse from the end of March to the beginning of April, seedlings and transplanting in North China are generally planted in mid-late April. As long as the surface is not frozen, the earlier the seedlings are planted, the better. Sufficient soil moisture must be ensured before planting, and no watering after planting, so as to promote the root system of yam seedlings.

(6) topdressing is needed for 2-3 times during the whole growth period. When the seedling is about 10 cm high, it is combined with ploughing and weeding for the first time to topdressing fertilizer, generally applying 20 kg urea per mu. The key period for the growth and expansion of potato blocks is from August to mid-September, which is usually spread with 10 kg potash fertilizer per mu and applied to the root cracks, and then irrigated with horse racing water. At the same time, potassium dihydrogen phosphate was sprayed on leaves every 10 days in sunny afternoon, for a total of 3 times.
