Camellia oleifera seedling cultivating medium and preparation method thereof

Abstract

The invention provides a camellia oleifera seedling cultivating medium. The medium is prepared from the following raw materials in percentage by volume: 40-60 percent of straws, 10-30 percent of grass carbon, 10-30 percent of cotton straws, 5-15 percent of biogas residues, 10-20 percent of sawdust pulp and 5-10 percent of perlite. The method for preparing the camellia oleifera seedling cultivating medium comprises the following steps: (1) grinding each raw material, screening, and preparing backup mixture according to the corresponding volume ration; (2) adding 5 percent by mass of active microorganism into the backup mixture, and fermenting for 40-60 days in a windrow or bulk manner at 60-65 DEG C to obtain a mixed fermentation broth; and (3) inspecting the quality of the mixed fermentation broth, and adding 2 percent by mass of a biological bactericide after the mixed fermentation broth passes the inspection so as to obtain the camellia oleifera seedling cultivating medium. The camellia oleifera seedling cultivating medium has the advantages of high seedling survival rate and good growth vigor, can be used for shortening the growing cycle and improving the production efficiency, and 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 camellia seedling cultivation substrate and a preparation method thereof. Background technique [0002] Camellia oleifera, (Latin name Camellia oleifera Abel.) Alias: tea seed tree, camellia oleifera, white flower tea; Camellia oleifera belongs to Theaceae, small evergreen tree. Because its seeds can extract oil (tea oil) for consumption, hence the name. Camellia oil is a high-quality edible oil with clear taste and fragrance, rich nutrition and storage resistance; it can also be used in industry as lubricating oil and anti-rust oil. Tea cake is both a pesticide and a fertilizer, which can improve the water storage capacity of farmland and control rice field pests. The peel is the raw material for extracting tannin. The seeds contain more than 30% oil, which can be used for food, hair conditioner, medicine preparation, candles and soaps, and can als...

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
