Yellow peach fertilization time, what kind of fertilizer is good

Young trees can apply 20g nitrogen fertilizer in the middle of February, mainly control shoots after August, mostly use phosphorus and potassium fertilizer, dig deep holes after October, and each plant can apply 20-50kg of rotten pig manure and cow manure and calcium magnesium phosphate fertilizer 1kg. Adult trees: in the middle of February, each plant can apply bio-organic fertilizer 2kg, 45 compound fertilizer 0.5kg, and then dig deep holes on both sides of the crown in September, each plant can apply bio-organic fertilizer 3-5kg, farm manure 40-80kg.

1. Fertilization time for young trees

The main results are as follows: 1. In the middle of February, in order to promote the sprouting and shoot growth of young yellow peach trees, 20 g nitrogen fertilizer can be applied to each tree again one month later, which should not be too much to avoid excessive branch growth and tree weakness.

2. After sprouting, young yellow peach trees need to be watered once a week, continuously for 3-4 weeks, and keep small water frequently. Yellow peach young trees need base fertilizer in autumn, which is mainly organic fertilizer, the dosage is 150-225kg/hm2, and calcium superphosphate 15kg/hm2 and urea 1.5-3.0kg/hm2 are applied at the same time.

3. In general, young trees planted for 1-2 years should be fertilized many times to expand the crown, and the principle of frequent and thin application was generally adopted, mainly quick-acting nitrogen fertilizer in the early stage, then mixed with mature human and animal feces and urine or biogas liquid, and proper amount of superphosphate leaching solution was added. Topdressing began one week before shoot release, once every 10-15 days, 2-3 times in a row.

After April and August, shoots are mainly controlled, and more phosphorus and potassium fertilizers are used during this period, which is beneficial to the aging of shoots and the differentiation of flower buds. After October, each plant can be dug deep holes, and each plant can be treated with decayed pig manure and cow manure 20-50kg, calcium magnesium phosphate fertilizer 1kg.

2. Fertilization time of adult trees

1. Generally, before sprouting in the middle of February, each plant can apply bio-organic fertilizer 2kg and 45 compound fertilizer 0.5kg, which can be applied in a circular trench, and then before the hard core, it can be mainly applied with available phosphorus and potassium fertilizer, and each plant can be leached with 50-100kg of rotten bran water, high potassium compound fertilizer or potassium sulfate 0.25-0.5kg. At this time, the fruit expands rapidly, new shoots and roots begin to grow, and a lot of nutrients are needed.

2. Yellow peach trees with strong tree potential can be applied less, and then compound fertilizer (15:15:15) is applied two weeks before fruit picking, and each plant can apply 0.5-1kg, urea 0.25-0.5kg, holding boron 50g, mainly to restore tree potential.

3. Then dig deep pits on both sides of the crown in September, which are 1.5-2m long, 35cm wide and 50cm deep. Each plant can apply bio-organic fertilizer 3-5kg and farm manure 40-80kg. With the increase of fruit hanging in the crown, the amount of fertilizer used increases gradually.

4. Generally, the topdressing of mature yellow peach trees is mainly nitrogen fertilizer before sprouting, and urea 450-600kg/hm2 is applied to each hole. Each tree can dig 4-5 20 cm deep application holes, which need to be watered in time before germination, and should not be watered too much during the fruit setting period. Compound fertilizer is mainly applied once in the fruit expansion period of yellow peach, with a dosage of 450-600kg/hm2. Generally, after the middle of July, it is necessary to control the amount of nitrogen fertilizer and irrigation water, and appropriately increase the application of phosphorus and potassium fertilizer to avoid plant overgrowth. At the same time, it is beneficial to promote flower bud differentiation.
