Problems solved by technology

[0004] In order to solve the problems of high cost, unsatisfactory control effect, high toxicity, environmental pollution and damage to soil micro-ecology existing in the existing technology for preventing and controlling soil-borne diseases, the present invention has developed a seedling-raising substrate and disclosed its preparation method at the same time. The seedling substrate can not only prevent and control soil-borne diseases, but also avoid and repair soil continuous cropping obstacles. It is an efficient, environmentally friendly, and low-cost seedling substrate

Embodiment 1

[0020] Embodiment one: the seedling-raising matrix of the present invention, its composition is to form by mixing the chaff of biocontrol bacteria and soil, the mass ratio of chaff of biocontrol bacteria and soil is 7:3, and described biocontrol bacteria comprises Trichoderma, mucilage Any one, two or more of Bacillus, Bacillus, and Pseudomonas, and the soil is peat soil or cultivation soil.

[0021] The method for preparing the seedling-raising substrate includes the following steps: (1) fermentation of edible fungus chaff: crushing the edible fungus chaff with a water content of 40-60% and adjusting the pH value to 7-8, and then feeding the edible fungus Add urea to the bran for compost fermentation;

[0022] Edible fungus chaff is the waste left after cultivating Flammulina velutipes, shiitake mushrooms, fungus, etc. It can be crushed into 1-3cm pieces. When measuring the pH value of fungus chaff, fungus chaff and pure water are generally used according to the mass ratio of...

Embodiment 2

[0064] Embodiment two: the seedling-raising matrix of the present invention, its composition is mixed by biocontrol bacterium chaff and soil, and the mass ratio of biocontrol fungus chaff and soil is 9:1, and described biocontrol bacterium comprises Trichoderma, sticky broom Any one, two or more of mildew, bacillus, and pseudomonas, and the soil is peat soil or cultivation soil.

[0065] The method for preparing a seedling-raising substrate includes the following steps: (1) fermentation of edible fungus chaff: crushing edible fungus chaff with a water content of 40-60% and adjusting the pH value to 7-8, and adding the edible fungus chaff to the Add urea for compost fermentation;

[0066] (2) Add biocontrol fungus spores to the edible fungus chaff fermented in step (1), and after fermentation and cultivation of the biocontrol fungus, the biocontrol fungus chaff is obtained;

[0067] (3) The chaff of the biocontrol bacteria obtained in step (2) is mixed with soil to obtain a se...

Embodiment 3

[0085] Embodiment three: the seedling raising substrate of the present invention, its composition is mixed by biocontrol fungus chaff and soil, and the mass ratio of biocontrol fungus chaff and soil is 8:2.5, and described biocontrol bacteria comprises Trichoderma, sticky broom Any one, two or more of mildew, bacillus, and pseudomonas, and the soil is peat soil or cultivation soil.

[0086] The preparation method is the same as in Example 2. Adopt biocontrol bacterium to be bacillus and Glycium bacillus to mix and carry out the test, the following is the test part, select the test of the influence of the seedling-raising substrate of the present invention on the pepper character; The pepper seed is accelerated germination 3-4d in 25 ℃ of incubators, sowing when the bud is white , Wait for the second true leaf to grow to about 30 days after emergence. The following indicators were measured, and the results are shown in the table below:

[0087] Continuous cropping ye...

Abstract

The invention discloses a seedling culturing matrix which is formed by biocontrol mushroom residues and soil in a mixed mode. The weight ratio of the biocontrol mushroom residues to the soil is 7-9:1-3. Meanwhile, the invention discloses a preparing method of the matrix, and the method comprises the steps that (1) edible mushroom residues are subjected to fermentation; (2) biocontrol mushroom spores are added to the edible mushroom residues after fermentation in the step (1), the biocontrol mushroom residues are obtained; (3) the biocontrol mushroom residues and the soil are mixed, and the seedling culturing matrix is obtained. The method has the advantages that successive cropping obstacles and soil-borne diseases can be prevented at the same time, the problem that in the prior art, beneficial bacteria are killed when the soil is subjected to disinfection, so that the effect of successive cropping obstacle repairing is not achieved is solved, and the bad side effect of environment pollution generated when chemical pesticides are used for treating soil diseases can be avoided, the method is a very important technology for using vegetable protected area soil in a sustainable mode, and high popularization value is achieved.

Description

technical field [0001] The invention relates to the technical fields of recycling waste after cultivating microorganisms, cultivating vegetables, and biological control, and in particular relates to a seedling-raising substrate and a preparation method and application thereof. Background technique [0002] In recent years, the intensification of vegetable cultivation in protected areas, high-density simplification and repeated planting environment have provided suitable conditions for the accumulation and spread of soil-borne pathogens, and the occurrence of soil-borne diseases has become increasingly serious. Various crop bacterial diseases, fungal diseases and root diseases Knot nematodes are prevalent in a large area, resulting in greatly reduced crop yield and quality, which seriously restricts the production and development of crops in protected areas. If not controlled, it will cause serious production reduction or even extinction of commercial crops. [0003] In order...
