How to Apply Biological Fertilizer to Fruit Trees

July 23, 2020

There are many varieties of fruit trees, which can be divided into sapling stages in one lifetime. At the beginning of the results, the demand for nutrient elements is different in each of the five periods of the fruiting period, the later stage of the results, and the senescence period. In the sapling stage, the growth of the roots and shoots is strong. Requires a large amount of nitrogen and phosphorus supply: During the result period, due to the large number of results, it also needs a large amount of nitrogen and potassium supply, especially in the full fruit period. In the aging period, nutrients need a trend, but in order to promote rejuvenation and maintain the tree vigor, The supply of nitrogen should not be too little.

The most important part of fruit tree fertilization is the application of basal fertilizer. The role of basal fertilizer is to improve the ecological environment of the fruit tree rhizosphere, enhance soil fertility and fertility, and provide sufficient nutrients for fruit tree growth and results in the coming year. Generally, 3 kg/plant compound microbial fertilizer is applied in the case of applying 20 kg organic fertilizer per plant.

In addition to basal fertilizers, the amount of top dressings for fruit trees generally accounts for 40% of the total annual fertilizer requirement. The role of topdressing is to timely supplement the urgent need of fruit trees for certain nutrients. Generally dwarf cultivation of young trees, application of composite biological fertilizer 0.5 ~ 1kg / .5 侏, in the early fruit period 1 ~ 1.5kg / 侏, full fruit period 1.5 ~ 3kg / strain.

The yield per tree varies greatly. For adult fruit trees, the N, P, and K fertilizers can also be determined based on the yield. For example, an apple 100kg yield should be topdressed with 0.4-0.7kg/plant, phosphorus 0.2-0.35kg/plant, and potassium 0.4-0.7kg/plant.
