1. Fertilizer and water management

In the middle and late stage of Chinese yam, fertilizer and water management must be indispensable. We have to apply fertilizer once when the stems and leaves of Chinese yam are covered with the whole shelf noodle, and the main fertilizer is urea, generally applying 20kg per mu or so. We can also apply some potash fertilizer or spray appropriate amount of foliar fertilizer to enhance the stress resistance and increase the yield of yam. Although the drought tolerance of Chinese yam is relatively strong, but in order to increase its yield. In case of dry weather, we should still pay attention to watering. However, on rainy days, stagnant water should be eliminated in time to avoid waterlogging, resulting in the death of yam due to stagnant water and lack of oxygen.

2. Pest control

Chinese yam in the middle and later period, there are also a lot of diseases and insect pests. Therefore, we should also pay attention to the prevention and control of diseases and insect pests, of which the most common diseases and insect pests are anthrax and root-knot nematodes.

If anthrax-like symptoms are found, then timely spraying should be carried out for prevention and treatment. In the initial stage of anthrax, mancozeb or carbendazim and other agents can be used for prevention and treatment, generally once a week, continuous spraying for about three weeks.

Until you see the tip of the yam tuber at the bottom of the yam ditch, then grab the top end of the yam with one hand, and then shovel off the lateral root behind the rhizome with the other hand, all the way to the root system attached to the ground, so that a complete yam can be removed.
