Sweet potato drought-resistant cultivation tips

Leave three leaves. When planting the potato seedlings with 6-7 nodes, only the top 3 unfolded leaves are left, and the rest, together with the leaves, are buried in the soil, and the buried parts should be sealed strictly. Bury your head. The sandy land absorbs heat quickly and the temperature is high. When planting potato seedlings, the tips and leaves exposed on the ground should be covered with soil. The thickness of the buried soil is more than 3 cm. 2-3 days after the potato seedlings take root, strip off the covered soil to expose the leaves. Dip in mud. Mix water and soil into mud before planting, dip the base of potato seedlings in the mud and plant them while they are wet. Root-boosting method. Cut the potato seedlings 7-10 days before planting, tie them into small handfuls, soak the base of the potato seedlings in clear water and thin mud to root, wait for the roots to grow to 5 cm long, water them hole by hole and plant them in the field. ABT method. Take 0.1g ABT rooting powder, dissolve it in warm water, mix it with 8kg water, soak the seedling base 2-3 nodes for 30 minutes, then plant. Deep hoe. Before planting, use a hoe to remove the surface dry soil on the sweet potato ridge, deep hoe (about 10 cm) twice, loosen the wet soil in the nest, and then plant, plough in time after planting to promote the seedlings to take root early.
