Problems solved by technology

[0004] At present, there are many brands of bio-organic-inorganic compound fertilizers at home and abroad, but the common problem is that the content of available nutrients is low, generally ≤10%, and the content of N, P, and K is low, which is difficult to meet the needs of crops, and additional chemical fertilizers are needed. And the added strains are all single strains, such as Bacillus nitrogen-fixing, Bacillus subtilis, silicate bacteria, etc., because the strains added to these fertilizers are single, it is difficult to exert multiple functions in production practice

Embodiment 1

[0029] Raw materials and their composition: 26% dried chicken manure, 42% rice bran, 3% sucrose, 15% urea, 6% superphosphate, 7% potassium sulfate, 1% zeolite powder, ATCC144712 ​​3.6-6.8×10 7 pcs / ml, CICC20026 milk vetch rhizobia 2.5-5.5×10 7 pcs / ml, ATCC6542 Pasteurella 2.1-3.8×10 7 pcs / ml, ATTC842 Paenibacillus polymyxa 3.5-6.5×10 7 Individuals / ml, ACCC10168 Bacillus megaterium 1.8-3.5×10 7 cells / ml, ATTC527 yeast 3.6-6.8×10 7 pcs / ml, ATTC161 filamentous bacteria 3.0-6.5×10 7 1 / ml, every 1kg compound microbial fertilizer contains 5-10ml microbial compound bacterial agent.

[0030] Preparation:

[0031] (1) According to the operation process of original bacteria activation-re-cultivation-expansion cultivation-solid fermentation-drying-crushing-drying;

[0032] (2) Steam sterilize the dried chicken manure and rice bran, then add sucrose and mix thoroughly;

[0033] (3) Insert the expanded bacteria in step (1) into the organic material in step (2), mix well, control t...

Embodiment 2

[0039] fertilizer test

[0040] The test site is set at Nanqiao Town, Lanling County, Linyi, Shandong Province. The fertilizer for testing is the compound microbial fertilizer (22-8-15) produced in Example 1. The crop for testing is capsicum, and the variety is "Big Mac".

[0041] In this experiment, 3 treatments were set up, arranged in random blocks, repeated 3 times, and the area of ​​the plot was 40m2.

[0042] Treatment 1: 30g of the test fertilizer was sprayed 10 days after the pepper was transplanted, at the flowering stage and the full fruit stage, and sprayed 3 times in total;

[0043] Treatment 2: 30g of conventional fertilization, spraying 10 days after pepper transplanting, flowering stage, full fruit stage, spraying 3 times in total;

[0044] Treatment 3: no fertilization, spraying the same amount of water.

[0045] In addition to spraying fertilizer solution according to the requirements of the plan, other management measures are the same as those of or...

Abstract

The invention discloses compound microbial fertilizer and a preparation method thereof and belongs to the technical field of agricultural bio-fertilizer. The fertilizer comprises dried chicken manure, rice chaff, cane sugar, urea, calcium superphosphate, potassium sulphate, zeolite powder, ATCC144712 azotobacter chroococcum, CICC20026 rhizobium astragali, ATCC6542 bacillus pasteurella, ATTC842 paenibacillus polymyxa, ACCC10168 bacillus megatherium, ATTC527 saccharomycetes and ATTC161 filamentous bacteria. According to the compound microbial fertilizer, through innovative technologies such as screening and matching, solid fermentation, negative pressure low temperature drying, two-section pelleting and particle high polymer material peridium for microbial bacteria, the novel biological environment-friendly type fertilizer integrating organic constituents and inorganic constituents is developed out, and the fertilizer has the advantages that the fertilizer consumption is reduced, the fertilizer utilization rate is raised, the agricultural product quality is improved, the environment is protected, and the fertilizer serves as a production means of green foodstuff.

Description

technical field [0001] The invention belongs to the technical field of agricultural biological fertilizers, and in particular relates to a compound microbial fertilizer and a preparation method thereof. Background technique [0002] The urgent requirement of modern agricultural production for multifunctional and comprehensive fertilizers makes the research and development of bio-organic-inorganic compound fertilizers have great potential. Although chemical fertilizers can increase production, if they are applied in large quantities for a long time, not only the benefit of increasing production will decrease obviously, but also the environment will be polluted. Traditional organic fertilizers not only have low effective nutrient content, but also consume a lot of manpower and material resources in the process of manufacture and application, and are unhygienic. Although biological fertilizers play a non-negligible role in agricultural production and improvement of soil ecolo...
