Method for orchard deep fertilization by using straw fiber fertilizer pipes

Abstract

The invention provides a method for orchard deep fertilization by using straw fiber fertilizer pipes, belongs to the technical field of straw comprehensive utilization technology and fertilization technology integration, and mainly solves the problem of surface fertilization of an orchard in the prior art. The method includes four steps that soil testing is conducted, the straw fiber fertilizer pipes in which a fertilizer is mixed are prepared, the fertilizer pipes are inserted into pre-drilled fertilization holes, wherein the distribution, number and depth of the fertilization holes are changed according to the age of trees, and the depth of the fertilization holes is 300-600 mm; the corresponding fertilizer pipes are matched with the fertilization holes, various nutrients can be added into hollow straw long fiber rods to prepare fertilizer rods to be inserted into the corresponding fertilization holes, the fertilizer rods need to be arranged in the annular band of water dripping of tree crown, and finally, reasonable hole fertilization and irrigation are conducted. The method achieves the effect of efficient use of water and fertilizers, and provides the technical support for development of fruit industries in arid regions.

Description

technical field [0001] The invention belongs to the technical field of integrated straw comprehensive utilization technology and fertilization technology, and in particular relates to a method for using straw fiber fertilizer pipes for deep fertilization in orchards. Background technique [0002] 1. The problem of shallow root system in orchards [0003] In recent years, the abuse, excessive application and low effective utilization rate of fertilizers have become a serious problem in the field of agricultural fertilization technology. In particular, long-term fertilization of a large amount of shallow soil in orchards has led to serious surfaceization of the root system in the orchard, and the direct consequences are premature aging, serious diseases and early degradation of the orchard; Utilization continues to decrease; at present, this vicious circle is still intensifying. [0004] Therefore, how to establish a reasonable fertilization system in orchards in my country ...

AI Technical Summary

Problems solved by technology

Although the Chinese government has issued a series of relevant policies and taken countermeasures against this problem, due to the large canopy and deep root system of fruit trees, if the deep fertilization technology cannot be solved, the shallow fertilization year after year will inevitably cause the root system of the plant to grow. The shallow distribution trend is not conducive to the lush and robust growth of plants

[0005] 2. Low utilization rate of straw resources

It is mainly to solve the problem of inconvenient use of powdery fertilizers in the vigorous growth stage of paddy field crops. The scope of use is relatively narrow, which is not conducive to widespread use and promotion.

[0012] Chinese patent 96243323 discloses "a kind of all-vegetarian long-acting column fertilizer" which is composed of a fertilizer stick and a degradable film coated on the surface of the fertilizer stick. The slow-release agent mixture is blended and extruded through the adhesive to form a rod-shaped body. The degradable film is a starch-based double-degradable film, which is integrated with the fertilizer bar, but it needs to be dried to become hard during the production process. Rod, and then coated with a starch-based double-degradable film on the surface, the procedure is complicated and the technology is single

[0013] Chinese patent 201220131658 discloses "a new type of wedge-shaped stick-shaped fertilizer" which is characterized in that the appearance of the fertilizer is wedge-shaped and stick-shaped, which is more convenient to apply, but the appearance of the fertilizer is only improved, and the technology is single

[0014] Throughout the invention of the current fertilization technology, we have not yet seen a technical method that can better solve the problem of superficial fertilization in orchards in my country, effectively improve the efficiency of fertilization in orchards, and effectively promote the extension of orchard roots to the deep soil
