What do you need to pay attention to when planting hemp yam? Please guide the cultivation of yam to pay attention to the following points: 1. Soil requirements: the land with flat ground, loose soil, deep soil layer, strong water and fertilizer conservation capacity and easy drainage should be selected, and sandy loam, light loam and loam are the most suitable soil. 2. selection of varieties and seedlings: varieties with strong, high yield, high quality and disease resistance should be selected. at present, there are many varieties cultivated in our county, such as stick medicine and small white mouth. When planting Chinese yam, uniform, neat and disease-free tubers should be selected and changed once every 4 to 5 years, so as to reduce the occurrence of variety degradation caused by successive years. 3. Sowing: take the ground temperature of 5 cm to 10 ℃ as the standard. Our county is usually in late April. 4. Fertilization: using chicken manure as base fertilizer is originally beneficial to the growth of Chinese yam, but if the chicken manure is not completely mature, it will compete with Chinese yam for fertilizer and water, and the number of underground pests will increase. On the contrary, it has an adverse effect on the growth of Chinese yam. 5. Medication: do not add more medicine, less water and use medicine blindly. The correct method of medication is to determine what kind of diseases and insect pests after the onset of the disease, and then prescribe a prescription for the disease. The concentration of pesticide should be appropriate, and different pesticides should be used alternately, which can not only improve the control effect, but also reduce the cost.
