Problems solved by technology

[0006] At present, there are many types of bio-organic fertilizers in my country, but not many are widely used. The main problem is that microbial organic fertilizers need to go through fermentation, decomposition and other processes, and at the same time need to add or retain an appropriate amount of beneficial microorganisms. Fertilizer also has the defects of high cost and unstable quality

Embodiment 1

[0047] The fermentation liquid of Trichoderma viride JUWEI002 described in Example 1 is obtained by fermenting Trichoderma viride (Trichoderma viride) JUWEI002 with strain preservation number CGMCC NO.7035 according to the prior art, and the number of live bacteria in the fermentation liquid of Bacillus subtilis JUWEI001 is ≥1 ×10 9 Individual / ml; Trichoderma viride JUWEI002 fermented liquid described in embodiment 2~3 is prepared according to the following method:

[0048] ① Inoculate the plate PDA medium with Trichoderma viride JUWEI002, and transfer to 2 generations;

[0049] ②Pick the mycelium from the edge of the colony and transfer it to the bran juice medium, culture temperature 28°C-30°C, 200rpm, culture time 36h, to prepare Trichoderma viride JUWEI002 culture medium;

[0050] ③Inoculate the Trichoderma viride JUWEI002 culture solution prepared in step ② into the bran juice fermentation medium with an inoculation amount of 5% (w / w). The fermentation conditions are: te...

Embodiment 2

[0081] A compound microbial organic fertilizer, the components are as follows, all in parts by weight:

[0082] 1 part of Trichoderma viride JUWEI002 fermentation broth, 1 part of Bacillus subtilis JUWEI001 fermentation broth, 22 parts of peat soil, 38 parts of tobacco residue, 38 parts of silkworm excrement, 6 parts of calcium powder, and 1 part of potassium fulvic acid.

[0083]The preparation method is the same as in Example 1.

[0084] Effects of the compound microbial organic fertilizer prepared in this example on the growth of watermelon and rhizosphere microorganisms in continuous cropping greenhouses (Heze, Shandong). The tested watermelon variety was Jingxin No. 1, and the application rate of 200kg / mu compound microbial organic fertilizer was used as the test group; the commercially available bio-organic fertilizer was used as the control group, and the application rate was 200kg / mu. During the experiment, all treatments did not use any fungicides and other base fert...

Embodiment 3

[0096] A compound microbial organic fertilizer, the components are as follows, all in parts by weight:

[0097] Trichoderma viride JUWEI002 fermentation broth 4 parts, Bacillus subtilis JUWEI001 fermentation broth 4 parts, peat soil 25 parts, tobacco residue 33 parts, silkworm excrement 33 parts, calcium powder 7 parts, potassium fulvic acid 1 part.

[0098] The preparation method is the same as in Example 1.

[0099] Effects of compound microbial organic fertilizer on strawberry yield and quality (Weifang, Shandong). The experimental variety is Baojiaozaosheng. Test group 1 applied 200kg / mu of this product, test group 2 applied commercially available microbial organic fertilizer 200kg / mu, and the control group applied farmyard manure (pig manure) 400kg / mu. The three kinds of fertilizers were applied at one time as the base fertilizer, and the protected land was cultivated conventionally.

[0100] The results are shown in Table 7. Compared with the application of farmyard m...

Abstract

The invention relates to a compound microbial organic fertilizer and a preparation method thereof. The compound microbial organic fertilizer is prepared from the following ingredients in parts by weight: 1-4 parts of trichoderma viride JUWEI002 fermentation liquor, 1-4 parts of bacillus subtilis JUWEI001 fermentation liquor, 20-30 parts of turfy soil, 33-38 parts of tobacco residue, 33-38 parts of silkworm faeces, 6-7 parts of calcium powder and 1-2 parts of potassium fulvate. The compound microbial organic fertilizer disclosed by the invention has the advantages that the quality of crops can be remarkably improved, the yield of the crops is increased, and the soil structure is improved.

Description

technical field [0001] The invention relates to a compound microbial organic fertilizer and a preparation method thereof, in particular to a compound microbial organic fertilizer which mainly takes tobacco residue and silkworm excrement and adds active compound bacteria, potassium fulvic acid and calcium powder, and belongs to biological fertilizers technology field. Background technique [0002] Soil is an important carrier of plant growth environment. It provides photosynthetic raw materials and attachment substrates for plants. Soil quality is closely related to crop yield. The basis of soil quality is soil fertility, which is the ability of soil to provide and coordinate nutritional and environmental conditions for plant growth, and is a comprehensive expression of various basic properties of soil. In recent years, with the rapid growth of population, in order to increase crop yield, people use a large amount of chemical fertilizers and pesticides, resulting in the redu...
