One, before the flower fat. Pre-emergence fertilization should be applied 15 days before flowering. Each apricot should be applied with 500g of nitrogen, 300g of potassium and 200g of phosphorus, mixed with human urine or mixed with human and animal feces and then applied to the top of the roots. The membrane promotes the absorption and utilization of water and fertilizer by the tree.
Second, after the flower fat. After flowering, the apricot trees consume a lot of nutrients. After flowering, young fruit grows rapidly. Young fruit and new shoots begin to thrive and require more fertilizer. The fertilization should be carried out 15-20 days after flowering. Nitrogen fertilizer is the main method. Each plant can apply 0.5 to 1 kg of nitrogen fertilizer and 250 g of boron fertilizer. Be careful to mix the farmer's fertilizer and spray the new high-fat film and spray it. Strong fruit Tiring liquid thickens fruit pedicles and improves nutrient delivery to prevent falling and fruit dropping (even every 3 to 7 days).
Third, apricot kernel fertilizer. At this point, apricot trees are lush and require a large amount of fertilizer. This time should be dominated by total potash fertilizer, supplemented by nitrogen and phosphate fertilizers, and NPK combined with farmhouse fertilizers will be effective. Each plant will use 300-500 g of potassium chloride.
Fourth, urging fruit fertilizer. 15-20 days before fruit picking, fruit enlargement speeds up. Potassium fertilizer can effectively increase apricot yield and fruit quality. Approximately 150 grams of potash fertilizer is used for every 50 kg of apricot fruit.
Fifth, post-harvest fertilizer. At this time, nitrogen and phosphate fertilizers should be the main, about 50 kg of apricot fruit, about 1.5 to 2 kg of nitrogen, phosphorus 1 to 1.5 kg, spraying a new high-fat membrane to enhance the ability of overwintering.
Six, make-up foliar fertilizer. Apricot trees can be foliar-fertilized from 20 days after leaf spreading to before leaf litting, and boron, zinc, manganese, and potassium fertilizers are effective. The amount of boric acid 0.1% to 0.25%, zinc sulfate 0.1%, manganese chloride 0.25% to 0.3%, potassium dihydrogen phosphate 0.3% to 0.5%, 0.2% to 1% of ferrous sulfate, the place where the thin soil is increased appropriately .
