How to fertilize apricot trees for high yields? Please explain in detail when to apply which fertilizer
To achieve high yields from apricot trees, you must manage fertilization at each stage well. For details, refer to the following methods:
1. Pre-bloom fertilizer. Fertilizer before bud break should be applied 15 days before flowering, with 500 g nitrogen, 300 g potassium, and 200 g phosphorus per apricot tree, mixed with human manure and urine or mixed with human and livestock manure and applied together with foliar topdressing, and sprayed with Xinhuzhimo (new high-fat film) to promote the tree's absorption and utilization of water and fertilizer.
2. Post-bloom fertilizer. After apricot trees bloom, the tree body has consumed a lot of nutrients. After petal fall, the young fruit rapidly expands, and the young fruit and new shoots begin vigorous growth, all requiring more fertilizer. This fertilization should be carried out 15-20 days after flowering, mainly with nitrogen fertilizer, applying 0.5-1 kg nitrogen fertilizer and 250 g boron fertilizer per tree. Be sure to mix it with farmyard manure and apply it together with a spray of Xinhuzhimo (new high-fat film). At the same time, spray Zhuangguodiling liquid to thicken the fruit stalk, increase nutrient transport, and prevent flower and fruit drop (spray 3 times consecutively at intervals of 7-10 days).
3. Apricot pit fertilizer. At this time, the apricot tree is vigorous and has a high fertilizer demand. This time, mainly use full potassium fertilizer, supplemented by nitrogen and phosphorus fertilizers, and applying nitrogen, phosphorus, and potassium in combination with farmyard manure has a very good effect, with 300-500 g potassium chloride per tree.
4. Fruit-promoting fertilizer. 15-20 days before harvest, the fruit expansion rate accelerates. Applying potassium fertilizer can effectively increase apricot yield and fruit quality, with about 150 g potassium fertilizer per 50 kg of apricots.
5. Post-harvest fertilizer. At this time, mainly use nitrogen and phosphorus fertilizers, with about 1.5-2 kg nitrogen and 1-1.5 kg phosphorus fertilizer per 50 kg of apricots, and spray Xinhuzhimo (new high-fat film) to enhance winter hardiness.
6. Supplementary foliar fertilizer. Apricot trees can be given foliar fertilizer from after leaf expansion until 20 days before leaf fall, and boron, zinc, manganese, and potassium fertilizers have better effects. The amounts used are 0.1%-0.25% boric acid, 0.1% zinc sulfate, 0.25%-0.3% manganese chloride, 0.3%-0.5% potassium dihydrogen sulfate, and 0.2%-1% ferrous sulfate. In places with thin and poor soil, appropriately increase the application.
