Precautions for fertilization after harvesting
After harvesting the grapes and before wintering, the nutrients of the tree are transferred from the fruit before harvesting to the accumulation, and the second growth peak appears in the roots. At this time, fertilization is very important, which is the second year of high-yield grapes. It has a decisive role.
1 Foliar spray fertilizer: In this period, the resistance of grape leaves is strong, and the concentration of foliar fertilizer can be increased appropriately. Foliar spray is applied with 0.5% urea and 0.5% potassium dihydrogen phosphate.
2 Early topdressing: After picking the fruit, it is necessary to apply a quick-acting fertilizer immediately. For late-maturing varieties, it should be applied before harvesting, and apply 20 kg of potassium sulphate compound fertilizer or fruit tree special fertilizer per mu.
3 Applying the base fertilizer: After harvesting the grapes, the effect of applying the base fertilizer before harvesting is good. When the root system is in the active period, the roots can be restored and the roots can be restored, and it can play a positive role in the nutrient accumulation of the tree. 3,000 kg of high-quality soil and fertilizer, 15 kg of pure nitrogen, 15 kg of pure phosphorus, 25 kg of pure potassium, 25 kg of biological calcium fertilizer, 2 kg of zinc sulfate, 2 kg of ferrous sulfate, 0.5 kg of borax, 60% of nitrogen 50% of potassium is left as top dressing, and the rest of the fertilizer is applied to the fertilization ditch 30 cm deep and 40 cm wide. Whether it is to apply quick-acting fertilizer or autumn-based fertilizer, it is necessary to timely water, soil the soil, promote the rapid decomposition of fertilizer, restore the tree potential, accumulate nutrients, and provide sufficient nutrition for the second year of grape growth, flowering and fruiting.
