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 bette

Embodiment 1

[0033] Embodiment 1 The preparation of multifunctional biological compound fertilizer of the present invention

[0034]Select industrial and agricultural waste such as livestock and poultry manure, straw and mushroom residue, adjust the C / N value to 20, the pH value to 6.0, and the moisture content to 50%, and ensure that the temperature of the material reaches 50°C and is maintained for more than 6 days to completely kill the waste. Eliminate bacteria and eggs. After the fermentation is over, no enterobacteria can be detected, and the germination index of the seeds should be higher than 60%. The fresh compost should be air-dried indoors for 5-7 days, and the water content should be less than 15%. Organic compost is used as a carrier to absorb liquid bacillus Compound bacteria. Bacillus compound bacteria agent is composed of Bacillus subtilis which can antagonize pathogenic bacteria, Bacillus megaterium which can dissolve phosphorus and Bacillus mucilaginosus which can dissol...

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...
