Bio-compound fertilizer suitable for Jiaodong fruit tree areas and preparation method thereof

Abstract

The invention relates to a bio-compound fertilizer suitable for Jiaodong fruit tree areas and a preparation method thereof. The bio-compound fertilizer comprises the following components by weight: 65-80 parts of an organic raw material, 10-20 parts of seaweed residue, 3-8 parts of glucosaminoglycan, 2-5 parts of medium trace element, 0.6-1.5 parts of a PGPR preparation, 0.6-1.5 parts of polyglutamic acid, 0.6-1.5 parts of a polyaspartic acid potassium salt, and 4-8 parts of plant ash. The bio-compound fertilizer provided by the invention can effectively improve the problem of low organic matter content of soil in Jiaodong area, and also can retain moisture and fertilizer. Synergistic components in the product can effectively improve the soil acidification problem in Jiaodong area, improve the adverse resistance of fruit trees, and alleviate the aging problem of Jiaodong fruit trees to certain extent, and can improve the microenvironment of soil microorganisms, enhance the survival competitive ability of the PGPR preparation, and prevent and control diseases.

Description

technical field [0001] The invention relates to the field of agricultural chemical fertilizers, in particular to a biological compound fertilizer suitable for the fruit tree area of ​​Jiaodong. Background technique [0002] Since the 1990s, high-quality fruits represented by red Fuji apples in Jiaodong, Shandong have become popular, and Jiaodong has also become a high-quality fruit producing area in China and the world. With the increasing fruit production, the chemical fertilizers used in orchards And there are more and more pesticides, which bring a variety of damaging problems to the soil ecological environment of Jiaodong orchard. Including: poor organic matter, serious soil acidification, massive reproduction of pathogenic microorganisms, imbalance of medium and trace elements, etc. [0003] (1) Soil acidification. The soil pH value of northern fruit tree varieties suitable for planting in Jiaodong area is 6.5-7.5, that is, growth and normal results in a neutral envir...

AI Technical Summary

Problems solved by technology

[0005] (3) The aging of fruit trees is serious, the resistance is reduced, and the ability to resist stress (freeze resistance, resistance to diseases and insect pests, and drought resistance) is poor

At the same time, due to changes in the physical and chemical properties of the soil, the growth of some beneficial microorganisms (ammonifying bacteria, nitrifying bacteria, etc.) is inhibited, while some harmful microorganisms are rapidly multiplied, and the fruit tree is seriously damaged. Use of medicines to control, causing serious pollution to the environment and agricultural products

[0006] (4) Unbalanced supply of medium and trace elements, calcium deficiency is common, half of them are zinc deficient, and 1 / 3 are boron deficient

[0007] On the other hand, the age of fruit trees is increasing year by year, and their ability to resist diseases and stresses is getting worse, which leads to weakening of tree vigor and decline in fruit quality.
