Embodiment 1

[0045] Preparation and application of embodiment 1 core biocontrol fungus and tea saponin

[0046] 1 Preparation of core biocontrol agents

[0047] 1.1 The active ingredient of the core biocontrol fungus of the present invention is Trichoderma harzianum (harzianum) 8.5×10 8 cfu / g and hygrospinocus var. beigingenis 4.0×10 8 cfu / g, the total effective number of viable bacteria is 12.5×10 8 cfu / g. Among them, Trichoderma harzianum (harzianum) was purchased from China Agricultural Microorganism Culture Collection Management Center, platform resource number: 1511C0001ACCC30371, and hygrospinocus var. beigingenis was purchased from China Agricultural Microbiology Culture Collection Management Center, platform resource number: 1511C0001ACCC40052.

[0048] 1.2 The preparation process of the core biocontrol agents is as follows:

[0049] 1) Preparation of spore powder of Streptomyces hygroscopicus:

[0050] ①Slant culture: Inoculate the original strain of Streptomyces hygroscopic...

Embodiment 2

[0097] Embodiment 2 The preparation of the organic fertilizer that contains core biocontrol fungus

[0098] 1 preparation

[0099] 1.1 Composition of the organic fertilizer containing the core biocontrol fungus (by weight): 5 parts of the core biocontrol fungus, 5 parts of tea saponin, 82 parts of organic matter, and 8 parts of plant nutrients.

[0100] For the preparation method of the core biocontrol fungus, see "1. Preparation of core biocontrol fungus" in Example 1, and for the preparation method of tea saponin, see "2 Preparation of tea saponin" in Example 1. The organic matter is obtained by pulverizing rapeseed cake, bean cake and sesame cake and then fermenting them with microorganisms. The weight ratio of rapeseed cake, bean cake and sesame cake is 5:3:2. Microbial fermentation was carried out by first using Bacillus subtilis (purchased from China Agricultural Microorganism Culture Collection Management Center, platform resource number is 1511C0001ACCC10118), Trichod...

Embodiment 3

[0104] Embodiment 3 The fertilization effect test of the organic fertilizer containing core biocontrol bacteria

[0105] Due to the extensive use of chemical fertilizers for a long time, the amount of organic fertilizers has become less and less, or even not used. Because chemical fertilizers did play a significant role in increasing crop yields when they were first used, people ignored the application of organic fertilizers. It leads to soil compaction, poor air permeability and water retention, decreased organic matter, significantly increased pests and diseases, and decreased crop quality, especially vegetables and fruit products have lost their original taste. Therefore, more and more people have begun to research on the production and application technology of organic fertilizers, especially bio-organic fertilizers. At present, many brands of bio-organic fertilizers have appeared on the market, and they occupy a considerable proportion. However, the application of bio-or...

Abstract

The invention relates to the microbial fertilizer field, and particularly relates to a core bio-control bacteria and an organic fertilizer containing the core bio-control bacteria. Effective components of the core bio-control bacteria are harzianum and hygrospinocus var. beigingenis. The organic fertilizer comprises following components by weight: 3-7 parts of the core bio-control bacteria, 3-7 parts of tea saponin, 75-89 parts of organic materials and 5-11 parts of plant nutrients. The invention also provides a method of preparing the organic fertilizer containing the core bio-control bacteria. According to the organic fertilizer containing the core bio-control bacteria, the core bio-control bacteria can effectively prevent or relieve disease harm and pest harm which are caused by continuous cropping, and has a function of microbial remediation of soil pollution; the tea saponin has functions of repelling injurious insects and biotin; and the organic materials in the fertilizer can promote formation of a soil granular structure.

Description

technical field [0001] The invention relates to the field of microbial fertilizers, in particular to a core biocontrol bacterium and an organic fertilizer containing the core biocontrol bacterium. Background technique [0002] The production of ecological agriculture needs the soil to provide the nutrients and living environment for crop growth and reproduction, but the over-exploitation of agriculture, especially the long-term partial application of simple chemical fertilizers, has caused many problems. Such as single nutrient, soil structure damage, low fertilizer utilization rate, poor taste of fruits and vegetables, etc. Bio-organic fertilizer is a resource-saving and environment-friendly fertilizer that can improve crop quality, improve soil, provide balanced fertilizer supply, and have obvious fertilizer efficiency. The existing biological fertilizers in my country are all based on organic matter, and then mixed with bacterial agents and inorganic fertilizers. The ap...
