Trichoderma harzianum-contanining functional vegetable seedling biological matrix and preparation method thereof

Abstract

The invention provides a trichoderma harzianum-contanining functional vegetable seedling biological matrix and a preparation method thereof. The functional vegetable seedling biological matrix is formed by adding a functional bacterial strain, namely the trichoderma harzianum SQR-T037, into a common seedling matrix. As for seedlings such as cucumbers, eggplants and watermelons, the specific fungus trichoderma harzianum SQR-T037 is selected, is kept alive and is added into the matrix to obtain an active biological matrix product, and by using the product, the plant growth promoting effect on seedling stages of seedlings such as the cucumbers, eggplants and watermelons is good, and high-quality seedlings of which the rhizospheres include a large amount of microorganisms with an activity function can be cultivated; meanwhile, the beneficial microorganisms can be in large-scale colonization at the rhizospheres of the seedlings, so that the growth of the cultivated seedlings in the later cultivation process can be promoted, the yield of the crops planted in a big field is improved, and the effect of preventing and controlling a cucumber soil-borne disease of the cultivated seedlings is achieved.

Description

technical field [0001] The invention belongs to the field of agricultural microorganisms, and relates to a functional vegetable seedling-raising biological matrix containing Trichoderma harzianum and a preparation method thereof. Background technique [0002] With the development of facility agriculture at home and abroad, more and more attention has been paid to industrialized seedling cultivation. According to incomplete statistics, the area of ​​crops that need to be raised in my country is very large, among which the planting area of ​​rice exceeds 300 million mu / year, and the area of ​​economic crops exceeds 500 million mu / year. At present, in China, materials rich in organic matter (such as peat, decomposed plant residues, etc.) are mainly used, and an appropriate proportion of light inorganic materials, such as vermiculite and expanded perlite, are used to make seedling substrates. Since the source of materials is limited by region and cost, and peat is a non-renewab...

AI Technical Summary

Problems solved by technology

Microbial organic fertilizers have the effect of disease prevention and growth promotion, but because of the high salt content of the bio-organic fertilizer, Ec>6.0ms / cm (the ratio of fertilizer to water is equal to 1:5, the data measured by the Ec determination method of the same substrate), while the seedlings are resistant to salt Concentration-sensitive specific biological characteristics lead to fertilizers that cannot be used for seedling growth, and the growth-promoting effect of adding microorganisms directly to the soil is not obvious. Therefore, those skilled in the art cannot determine whether adding it to the seedling-raising substrate can play a role in promoting growth effect
