Preparation method of organic substrate suitable for culturing fruit trees on sand-gravel land

Abstract

The invention discloses a preparation method of an organic substrate suitable for culturing fruit trees on sand-gravel land. The method comprises the following steps of dispensing, preparation, fermentation and compounding to prepare the organic substrate which has high ventilation performance and high hydroscopicity and is rich in trace elements and nutrient components. The preparation method of the organic substrate suitable for culturing fruit trees on sand-gravel land is optimally selected by means of continuous exploration and research on the basis of years of preparation practice on an organic culture substrate for various varieties of fruit trees. By culturing fruit trees such as apricot trees, peach trees and grape trees with the substrate, a water-fertilizer environment for the growth of the fruit trees can be created, the resource utilization ratio is increased, the stress tolerance of the cultured fruit trees is improved, fertility balance, soil moisture conservation and ventilation are facilitated, and the development of root systems is promoted.

Description

technical field [0001] The invention relates to a method for preparing an organic matrix suitable for the cultivation of fruit trees on sandy ground Background technique [0002] It has become an important model to improve the ecological environment by using sand and gravel to plant economic forests to develop ecological agriculture. The core technology of cultivating fruit trees on sand and gravel is organic substrate cultivation, and the quality of the cultivation substrate plays a very important role in the growth of fruit trees, especially young trees. At present, in the cultivation of fruit trees in gravel land, soil replacement and fertilization are mostly used. In actual production, this method is affected by the physical and chemical properties of the soil, which directly affects the survival rate of seedling planting and the normal growth of seedlings. In addition, the fertilizer in the planting hole is not fully mixed with the soil, especially if the unripe livest...

Problems solved by technology

In addition, the fertilizer in the planting hole is not fully mixed with the soil, especially the contact between the undecomposed livestock manure and the root system, which will cause the roots of the seedlings to burn.
