Cut off the branches that can't be revived, strengthen Toby's underground data management, fully obtain the nutrition and water of promising eggplant buds, and make the buds sprout neatly and grow sturdily. After the roots cross the East China Sea, plastic arcades are filled on the roots to rejuvenate and take root, and improve the absorption function. When the loss is serious, the inflorescence should be greatly reduced, the fruit yield should be controlled or not, the nutrient consumption should be reduced, and the tree growth should be restored. Spraying rooting agent or amino acids, humic acid and other substances to promote root growth on soil can promote the normal germination and growth of branches. Usually, after 20 days, the muddy roots of the dough can revive and produce a large number of new roots.
Control the growth of branches and vines If the roots are frostbitten plants, we should trim the number of branches and shoots according to the injury of the roots, reduce the nutrient and water consumption of Su Guo on the ground, and realize the balance between supply and demand of nutrients on the ground and underground. The East China Sea, that is, crops freeze at a low temperature below 0, which is harmful to crops. Low temperature chilling injury mainly refers to that the temperature of crops is lower than the temperature needed for growth and development, which leads to the delay of crop growth period, the damage of physiological function of reproductive organs and the threat of growth.
Some varieties were harvested late, and there was less nutrient countercurrent accumulated in the later period of wood, so eggplant did not grow fully. Or, due to plant diseases and insect pests, grapes fall early, resulting in insufficient nutrition of trees. Improper fertilization method and time lead to malnutrition of trees and easy occurrence of East China Sea. There are more extreme weather, snowy and windy in winter, vines often suffer from weather below extreme low temperature, and grapes suffer from freezing injury. Due to the long cold in late spring, the temperature rises rapidly in March and April, and the eggplant loses water. The soil temperature rises later than the atmospheric temperature, and the roots can't absorb soil moisture, which leads to the "dry" of grape branches.
Every spring, especially in the upper reaches of grapes, there will be different degrees of cold current, even sub-zero temperature and freezing, which will freeze the grapes. Most grape varieties planted in our city belong to Eurasian species, which have no cold tolerance and are prone to the East China Sea. Especially for late-maturing and late-harvesting varieties, the lunar hole performance is poor. The planting links are thick, the soil layer is shallow, there is a sticky layer, or furrow fertilization is not needed. The quality of saplings is poor, and the roots of seedlings in root nutrition pots are shallow. If you plant it by cultivating soil, the roots will float. Fertilized water is biased towards electricity, branches grow in the early stage, nutrition is insufficient in the later stage, and branches are empty. The uneven management level makes the trees in different States, resulting in the East China Sea.
