Fertilization methods of apricot trees

Apricot is cultivated in many parts of our country, and its fruit is colorful and delicious, and it has high health care value. In its growing period, if it wants to pass its yield, it needs reasonable fertilization. So how to fertilize apricot trees? Let's get to know it.

1. Base fertilizer

Base fertilizer is the main fertilizer for apricot trees in a year, which is mainly composed of manure, compost, human feces and urine which are rich in organic matter, and can also be mixed with some nitrogen fertilizer to speed up the fertilizer effect. After application, calcium superphosphate and bone powder will mainly combine with calcium and iron in the soil, so it is not easy to be absorbed by apricot trees, so in order to give full play to the fertilizer effect, it can be accumulated and ripened with base fertilizer, and then used as base fertilizer. Base fertilizer is best applied in autumn, ploughing from September to October, and the temperature of early application is higher, which is not conducive to the overwintering of plants. The application of base fertilizer can increase the nutrition of tree storage, which is very beneficial to flower bud differentiation, flowering and fruit setting and new shoot growth in the coming year.

Second, topdressing

Topdressing is also called topdressing, and the effect of base fertilizer is stable and slow. when apricot needs a large amount of fertilizer, it must be replenished in time in order to meet the needs of its growth and development.

1. Pre-flowering fertilizer. Fertilization before bud is generally applied half a month before flowering. Generally, 500 grams of nitrogen, 300 grams of potassium and 200 grams of phosphorus are applied per plant, which can be mixed with human feces and urine. After fertilization, new high-fat film can be sprayed to promote the absorption and utilization of fertilizer and water.

2. Fat after flowering. Apricot consumes a lot of nutrients after flowering, and more fertilizer is needed for young fruit expansion and new shoot growth after flowering. Generally, 0.5-1 kg and 0.25 kg of boron fertilizer are applied to each plant 15-20 days after flowering. At the same time, new high-fat film and Zhuangguoling liquid can be sprayed to prevent falling flowers and fruits.

3. Hard nuclear fertilizer. At this time, apricot trees are exuberant and need a great amount of fertilizer, so it is appropriate to apply potassium fertilizer mainly, supplemented by nitrogen and phosphorus, with 300-500 grams of potassium chloride per plant.

4. Promoting fruit fertilizer

15-20 days before fruit harvest, the fruit expands faster, and the application of potash fertilizer can effectively improve the yield and quality, generally 150 grams of potash fertilizer is applied for every 50 kg of production.

5. Postharvest fertilizer. Nitrogen and phosphorus should be given priority to after fruit harvest, with 1 kg of phosphate fertilizer and 0.5-1 kg of phosphate fertilizer per plant. Spraying new high lipid film can enhance the overwintering ability of the plant.

6. Supplement foliar fertilizer. Apricot trees can be sprayed with foliar fertilizer to supplement boron, zinc, manganese and potassium 20 days before defoliation, but the concentration should be paid attention to.
