Seedling-cultivating medium for michelia alba and preparation method of seedling-cultivating medium

Abstract

The invention provides a seedling-cultivating medium for michelia alba. The seedling-cultivating medium comprises the following raw materials in percentage by weight: 40%-60% of straw, 10%-30% of rice chaff ash, 10%-30% of mushroom residue, 5%-15% of coal ash, 10%-20% of composting soil and 5%-10% of perlite. A preparation method of the seedling-cultivating medium comprises the following steps: (1) grinding the raw materials, and sieving to prepare a standby mixture according to a corresponding volume ratio; (2) adding 5% of active microorganisms into the standby mixture, and fermenting at 60-65 DEG C for 40-60 days in a strip stack manner or a pile manner, so as to obtain a mixed fermenting product; and (3) carrying out quality inspection on the mixed fermenting product, and adding 5% of a water-retention nutrient agent after the mixed fermenting product is qualified, so as to obtain the seedling-cultivating medium for the michelia alba. The seedling-cultivating medium has the beneficial effects that the survival rate of cultured nursery stocks is high, the growth vigor is high, the growth period is shortened, and the production efficiency is improved; and the seedling-cultivating medium is suitable for popularization and application.

Description

technical field [0001] The invention relates to the technical field of agricultural seedling cultivation, in particular to a white magnolia seedling cultivation substrate and a preparation method thereof.

Problems solved by technology

However, the following problems often occur when the existing seedling substrate is used in practice: the extension and attachment of the plant root system are limited, and its fixation and maintenance effects cannot be fully exerted; it cannot provide good water, fertilizer, air and heat for the plant root system , pH value and other conditions, it cannot give full play to the role of soil that is better than soil; it does not meet the requirements of modern production, operation and standardization are troublesome, and it is inconvenient to use. The effect is not very obvious
