How to control take-all disease after wheat turns green?
Wheat take-all disease, also known as black foot disease, is a typical root disease. It can occur throughout the entire growth period of wheat, and the pathogen only infects the roots and the basal 1-2 nodes of the stem. The severity of the disease is affected by many factors. Continuous cropping and repeated cropping make the disease severe; when wheat and summer corn are grown twice a year and continuously for many years, the disease occurs severely; low soil fertility and an imbalanced ratio of nitrogen, phosphorus, and potassium, especially in phosphorus-deficient plots, make the disease severe; rainy springs and high soil moisture are conducive to the disease.

Detailed Explanation of the Method for Raising Jujube Seedlings by Root Cutting and Returning to the Nursery
To raise jujube seedlings by root cutting and returning them to the nursery, first select plants of excellent quality and free from pests and diseases as mother plants. Before budbreak, dig a trench 30-40 cm wide and 40-50 cm deep around the outer edge of the mother plant's canopy to cut the jujube roots, and use scissors to trim the cut root wounds smooth. Apply decomposed organic fertilizer, about 75 kg per plant, mix it with moist soil, fill it into the trench and tread it firm. If conditions permit, it is best to irrigate thoroughly once. Then cover with a layer of loose soil to conserve moisture. After the jujube roots are stimulated, a large number of clustered root-sucker seedlings will appear on the ground near the trench in May-June. Management of the root-sucker seedlings should be strengthened in a timely manner. After budbreak, remove excess buds; the principle is to remove the dense and keep the sparse, and remove the weak and keep the strong, generally with a plant spacing of about 15 cm, so as to ensure normal growth of the seedlings.
