Abstract

The invention discloses a preparation method of a seedling culture substrate with a growth promoting function, comprising the following steps: steps 1, material preparation: taking 15.0-35.0 parts ofperlite, 15.0-35.0 parts of vermiculite and 30.0-70.0 parts of organic material according to parts by weight for later use; step 2, preparation of functional strain: selecting bacillus amyloliquefaciens as the functional strain in the fertilizer, wherein the functional strain is produced in the form of fungus powder, and the activity of the functional strain is not less than 3 hundred million / g; step 3, preparation of the seedling culture substrate with a growth promotion function: mixing the materials in steps 1, adding the functional strain in step 2 which accounts for 0.1-0.5% of the totalweight of the fertilizer in the mixing process, and uniformly mixing, so as to obtain the seedling culture substrate with a growth promoting function, wherein the activity of the strain is not less than 30 million / g. The seedling culture substrate cannot cause damage to the environment and crops, is safe, health, pollution-free, and thus is a novel green and environment-friendly, and simple and efficiency seedling culture substrate.

Description

technical field

[0001] The invention relates to the field of seedling raising, in particular to a preparation method of a seedling raising substrate with growth-promoting function. Background technique

[0002] Cultivating strong seedlings with well-developed root systems is particularly important for the vigorous growth and resistance improvement of crops after transplanting. At present, the research on the cultivation of strong seedlings mainly focuses on "the effect of using different substrate materials on seedling raising effect" and "the effect of adding hormones on seedling growth. The use of new substrate materials may cause the problem that the substrate materials cannot be decomposed and cause environmental pollution; while the application of hormones in the seedling raising process will bring about safety hazards in the environment, health and crop quality. It may lead to the disorder of crop growth and metabolism, and the growth disorder in the later stage. C...
