Strengthen water and fertilizer management, plant good yam

In the cultivation process of yam, due to improper management of fertilizer and water, it often causes waterlogging or drought; the nutrient supply in the growing season is not enough, which makes the yam severely reduce production and directly affects the yield.

First, the most important time in the late growth period

Topdressing is mainly in the middle and late stages of growth, and less fertilizer is needed in the early stage. In order to ensure high yield of yam, it is usually applied 2 to 3 times. If the growth of the late Spraying pedicle strong spirit + 0.2% potassium dihydrogen phosphate and 1% urea to ensure adequate swelling tuber elongation and nutrients. By spraying "If the pedicle strong spirit", to meet the nutrient supply a large amount of flowers and fruits, subsurface portion thickening nutritional transport vessel, to increase the amount of nutrient delivery, increase the speed of the ground fruit enlargement, and effective, non-toxic.

Second, control the water balance is the key

The upper part of yam is like high temperature and dry, afraid of frost, and it is not suitable for drought. If it is too dry, it will seriously affect the expansion of yam. Watering approximately in late April to mid-May, usually about 10 days during which time water permeable, in late May after watering should be properly watered according to soil moisture. Excessive watering can also cause rust, causing early leaves and affecting root yield. Farmers' recommended new lipid membrane yam spraying plant protection agents, foliar spray to form a protective film, reputation "transparent clothing plant health", disease prevention disinfection, dry hot wind and drought, waterlogging anti, the product of physically played No effect on drug resistance.

When planting yam , pay special attention to the management of the above two points, increase the amount of nutrient transport; enhance the resistance of yam, in order to produce high-quality yam and increase economic income.
