Sweet Potato Resistant to Drought and Planted Six Methods

First, leave 3 leaves method to take 6 to 7 sections of potato seedlings, planting leaves only the top 3 leaves, the rest with the leaves buried in the soil, the part of the soil should be sealed tightly. Second, buried Fasara land absorbs heat quickly, and the temperature is high. When planting potato seedlings, shoots and leaves exposed on the ground should be covered with soil. The thickness of buried soil should be 3 cm or more. After 2 to 3 days, the roots of the potato seedlings will be covered to cover the soil. , exposing leaves. 3. Before the planting method, the mud and mud shall be used to stir the mud, and the base of the potato shall be smashed and then wetted and planted. Fourth, the rooting method in the 7 to 10 days before planting the potato seedlings cut, bundled into a small handle, the base of the potato seedlings immersed in water and mud in the hair roots, until the root grows to 5 cm long, watering by hole-by-hole after planting Yu Datian. 5. Use ABT to take 0.1g of ABT rooting powder. Stir the water with 8 kg of water and dissolve it evenly. Soak the seedlings with 2 to 3 knots for 30 minutes. 6. Before the deep-season cultivation method, the sweet potato shall be smashed with dry earth on the top surface of the sweet potato and deep-smashed (about 10 per cent). The wet soil shall be loosened in the nest, and then planted. After planting, the cultivator shall be cultivated in time to promote rooting early.
