Multifunctional biological compound fertilizer as well as preparation method and application thereof

Abstract

The invention discloses a multifunctional biological compound fertilizer as well as a preparation method and an application thereof. The multifunctional biological compound fertilizer contains 18-20g*kg<-1> of organic matters, 0.2-0.5 hundred million CFU*g<-1> of total functional bacillus, 40 to 50g*kg<-1> of total N(N), 20-30g*kg<-1> of total P(P2O5) and 50-60g*kg<-1> of total K(K2O). The biological compound fertilizer is prepared by adopting rotten and dried organic fertilizer as an absorbing carrier, providing a good environment for storing and playing effect of the bacillus with specific functions and adding a small amount of fertilizer on the basis of the good environment. The multifunctional biological compound fertilizer integrates the advantages of organic fertilizer, microbial inoculum and fertilizer, and remains a large amount of beneficial microorganism. The multifunctional biological compound fertilizer has obvious effects of increasing production and yield when being applied in vegetables and grain crops, has effects to the crops of the season, has obvious promoting effects to the crop of the second season, has the effects of optimizing the microbial structures in soil and improving the ecological quality, can solve continuous cropping and soil with problems and belongs to an environment-friendly fertilizer.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizer production, and in particular relates to a multifunctional biological compound fertilizer, its preparation method and application. Background technique [0002] At present, fertilizers mainly include three types: chemical fertilizers, organic fertilizers and microbial fertilizers. [0003] The application of chemical fertilizers can significantly increase crop yields, and the economic benefits are relatively prominent. However, long-term large-scale application will not only reduce the yield-increasing benefits, but also cause other problems, such as causing soil compaction and lowering the quality of agricultural products; Eutrophication has caused the quality of my country's ecological environment to deteriorate. [0004] Organic fertilizer is rich in humus, which can not only maintain the balance of soil fertility, but also improve crop quality, but the effective nutrient conten...

AI Technical Summary

Problems solved by technology

[0003] The application of chemical fertilizers can significantly increase crop yields, and the economic benefits are relatively prominent. However, long-term large-scale application will not only reduce the yield-increasing benefits, but also cause other problems, such as causing soil compaction and lowering the quality of agricultural products; Eutrophication has caused the quality of my country's ecological environment to deteriorate

[0004] Organic fertilizers are rich in humus, which can not only maintain the balance of soil fertility, but also improve crop quality, but the effective nutrient content is low. If it is directly applied, it is difficult to increase crop yield and multiple cropping index, and cannot meet the nutrient requirements of crops in the early growth stage.

[0005] Although microbial fertilizers play a non-negligible role in agricultural production and improving the soil ecological environment, microbial fertilizers themselves do not contain nutrients and are an indirect fertilizer that cannot replace chemical fertilizers or organic fertilizers.

At the same time, the combination of microbial strains used in the currently developed bio-fertilizers is very random, often a simple mixture, without comprehensive consideration of the biological characteristics and functional combination advantages of the strains

In fact, the more types of microorganisms added are not the better, the random combination of microorganisms will also cause waste of resources, and the fertilization effect is often unstable

[0006] Patented inventions of domestic biological compound fertilizers, such as the patent application No. 99111130.3 and the patent application titled "High Efficiency Multifunctional Compound Microbial Fertilizer and Its Industrial Manufacturing Method" disclose a kind of mainly rhizobium-based, peat soil, sludge Composite microbial fertilizer as a carrier; in the patent application No. 99109167.1 and the title of the invention "A Composite Biological Fertilizer and Its Production Method", the inventor sterilized industrial and agricultural waste to produce composite biofertilizer, sterilized The treatment cannot retain beneficial microorganisms, and the realization of the technical solution requires the addition of sterilization equipment, which is not suitable for popularization in rural areas; the patent application number is 200610034219.9, and the title of the invention is "a special fertilizer for bananas capable of preventing banana wilt and its production method" In the patent application, the number of effective viable bacteria of enzyme bacteria is disclosed, which can prevent banana wilt, but it does not clearly state the specific microbial compatibility types and detection methods, nor does it comprehensively consider other nutrients needed by crops
