Autumn fruit trees to protect leaves
Autumn is the harvest season for orchards. At present, many late-maturing fruit trees have entered the harvest period one after another. While picking fruit, care should be taken to protect the leaves so that the trees can continue to store nutrients, and at the same time, fertilizers must be applied after the fruits are harvested. Protect the leaves from pests and diseases. Autumn fruit tree leaf nourishing has the following measures:
Spray fertilizer immediately after the fruit is sprayed 500 times amino acid liquid fertilizer, add 0.3% to 0.5% of urea and 0.3% to 0.4% of potassium dihydrogen phosphate mixture, interval 10 days or so, even spray twice to make up Nutrition, delays aging and shedding of leaves. The nitrogen fertilizer was sprayed twice in the first two weeks before the leaves, and 0.5% to 1% urea solution was sprayed on the leaves to increase the nitrogen nutrients stored in shoots and roots.
Early application of organic fertilizer as early as possible after fruit picking, the sooner the better. General adult tree strains apply 100 kg of farmyard manure with good quality, and apply appropriate amount of NPK fertilizer and biological fertilizer. Unconditional application of farmyard fertilizers, the best choice of nitrogen-based acid or humic acid fertilizers, coupled with application of biological fertilizer.
Fine pruning to do a good job in autumn pruning, timely sparse over dense branches, overlapping branches, pests and branches, etc., to reduce nutrient consumption.
