Double-controlled balanced fertilization method for apples

Abstract

The invention discloses a double-controlled balanced fertilization method for apples. The double-controlled balanced fertilization method is applicable to cultivation of vigorous-stock apples, and comprises the following steps: acquiring the circumferential length of the central trunk part of the trunk of a tree body, determining the yield and proper fruit-retaining amount per plant of the tree body according to the circumferential length of the central trunk part of the trunk, and removing flowers and fruits exceeding the proper fruit-retaining amount per plant of the tree body; acquiring thefertilization amount per plant according to the yield per plant, and respectively determining the application amounts of pure phosphorus and pure potassium; and carrying out regular and quantitativefertilization operation according to the fertilization amount per plant and the fertilization amounts of the pure phosphorus and the pure potassium. The double-controlled balanced fertilization methodprovided by the invention adopts two key measures of thinning of flowers and fruits and fertilization to regulate and control yield and tree potential, so the purposes of high yield, stable yield, high quality and maintenance of vigorous and moderate tree potential are achieved. In production, the yield, the quality and the tree potential are regulated and controlled mainly through two key measures of thinning of flowers and fruits and fertilization, so dynamic balance is achieved.

Description

technical field [0001] The invention relates to the technical field of fruit tree cultivation, and more specifically relates to a dual-control balanced fertilization method for apples. Background technique [0002] The determination of fertilization rate in the prior art is mainly based on the yield, and at the same time, it is determined with reference to the soil nutrient content. It is very simple to determine the fertilization rate according to the yield in production, but both soil analysis and leaf analysis require special agency testing, and it is difficult to achieve comprehensive accuracy. The reason is that apples Most of the orchards are built in hilly areas, and the soil conditions of different plots are very different (even the soil fertility of the same plot is very different). Therefore, it seems scientific in principle, but it is difficult to implement in practice, which leads to fruit farmers not applying fertilizer according to yield. The method is to ferti...

[0002] The determination of fertilization rate in the prior art is mainly based on the yield, and at the same time, it is determined with reference to the soil nutrient content. It is very simple to determine the fertilization rate according to the yield in production, but both soil analysis and leaf analysis require special agency testing, and it is difficult to achieve comprehensive accuracy. The reason is that apples Most of the orchards are built in hilly areas, and the soil conditions of different plots are very different (even the soil fertility of the same plot is very different). Therefore, it seems scientific in principle, but it is difficult to implement in practice, which leads to fruit farmers not applying fertilizer according to yield. The method is to fertilize blindly according to experience, which often results in excessive fertilization and the formation of flourishing trees, resulting in low yield and poor quality.
