Complex microbial inoculant, bio-fertilizer and preparation method

Abstract

The invention belongs to the technical field of biological fertilizers, and particularly relates to a complex microbial inoculant, a biological fertilizer and a preparation method. The complex microbial inoculant comprises a microbial inoculant and an adsorbent; the microbial agent is prepared from the following components in parts by weight: 30 to 40 parts of composite bacillus, 25 to 35 parts of trichoderma, 20 to 30 parts of actinomycetes and 5 to 15 parts of probiotics; the adsorbent comprises the following components in parts by weight: 10-35 parts of soybean cake powder and 25-55 parts of activated carbon; the bio-fertilizer is prepared from a carrier and a complex microbial inoculant, and the carrier and the complex microbial inoculant comprise the following components in parts by weight: 70-90 parts of the carrier and 10-30 parts of the complex microbial inoculant, by applying the complex microbial inoculant and the biological fertilizer, the fruit tree yellows can be effectively prevented and treated while the fertilizer requirement of the fruit tree is met, and a fruit tree nutrition balance system is conditioned.

Description

technical field [0001] The invention relates to the technical field of biological fertilizers, in particular to a compound bacterial agent, a biological fertilizer and a preparation method. Background technique [0002] With the expansion of the planting area of ​​fruit trees (such as apple trees, pear trees, cherry trees, peach trees, citrus trees, etc.), more and more plants suffer from yellowing disease, especially some adult fruit trees. Fruit tree yellowing disease is also known as mosaic disease. In the early stage, the main symptoms are: yellow leaves, leaf mosaic, mottled, etc. In the middle stage, the main symptoms are: the diseased fruit trees reduce or stop production, which is contagious; in the later stage, the main symptoms are: tree death , the whole orchard is severely infected and the whole orchard is destroyed. [0003] Experts believe that there are many causes of fruit tree yellowing disease, and it is difficult to effectively prevent and control all of ...

AI Technical Summary

Problems solved by technology

[0009] 1. It is difficult to determine the type of yellowing disease according to the characteristics of yellow leaves. If the cause cannot be confirmed, the prevention and treatment of yellowing disease cannot be carried out in time

[0010] 2. The prevention and treatment of each yellowing disease has limitations, and it is impossible to achieve active prevention and control

[0011] 3. The existing control methods are tree cutting or supplementation, which have no conditioning function and are relatively passive

[0012] 4. The prevention and control effect of yellowing disease is not good
