How to fertilize apricot trees can produce high yield? Please describe in detail when to apply what fertilizer apricot trees need to grasp the fertilization of each period in order to obtain high yield. for details, you can refer to the following methods: first, pre-flowering fertilizer. Pre-bud fertilization should be applied 15 days before flowering, 500 grams of nitrogen, 300 grams of potassium and 200 grams of phosphorus per apricot plant, and mixed with human feces and urine or human and animal manure were applied together with extra-root topdressing, spraying new high-fat film to promote the absorption and utilization of water and fertilizer. Second, fat after flowering. Apricot trees consume a lot of nutrients after flowering, young fruits expand rapidly after falling flowers, young fruits and new shoots begin to grow vigorously, all need more fertilizer. The fertilization should be carried out 15-20 days after flowering, mainly nitrogen fertilizer, 0.51kg nitrogen fertilizer and 250g boron fertilizer per plant. Be sure to spray new high-fat film mixed with farm manure, and at the same time spray Zhuangguotiling liquid to thicken the fruit pedicel. Increase the amount of nutrition to prevent flower and fruit drop (sprayed 3 times every 10 days). Third, apricot kernel fertilizer. At this time, apricot trees are luxuriant and need a large amount of fertilizer. This time, we should give priority to total potash fertilizer, supplemented by nitrogen and phosphorus fertilizer, and the effect of mixed application of nitrogen, phosphorus and potassium combined with farm fertilizer is very good, with 300 grams of potassium chloride per plant. Fourth, promote fruit fertilizer. The fruit expansion rate was accelerated 15-20 days before fruit picking, and the application of potassium fertilizer could effectively improve the yield and fruit quality of apricot, about 150 grams of potassium fertilizer per 50 kg apricot fruit. Fifth, postharvest fertilizer. At this time, nitrogen and phosphate fertilizer should be given priority to, about 1.5 kg of nitrogen and 1.5 kg of phosphate fertilizer should be applied every 50 kg of apricot fruit, and the new high lipid film should be sprayed to enhance the overwintering ability. Sixth, apply foliar fertilizer. Foliar fertilizer can be applied to apricot trees from 20 days after leaf spreading to 20 days before defoliation, and boron, zinc, manganese and potassium fertilizer have better effect. The dosage is 0.1% boric acid 0.25% boric acid, 0.1% zinc sulfate, 0.25% manganese chloride, 0.3% potassium dihydrogen sulfate, 0.5% ferrous sulfate and 0.2% ferrous sulfate.
