A kind of tomato seedling raising substrate and its preparation method

Abstract

The invention relates to a tomato seedling growing matrix. The matrix is mainly prepared from decomposed cow dung, Pleurotus eryngii bran, perlite, Bacillus subtilis, sands, corn stalks and terramycin herb residues. The matrix has the advantages of abundant and balanced nutrition, high porosity, good air permeability, good water absorption and drainage property, promotion of growth of microbes in soil, facilitation of growth of tomato seedlings, great improvement of the emergence rate and the quality of tomato seedlings, no use of peat or turf, resource saving, indirect avoiding of excessive exploitation of vegetations, and protection of the abundant and balanced nutrition of ecologic resources.

Description

technical field [0001] The invention belongs to the field of seedling-raising substrates, in particular to a tomato seedling-raising substrate and a preparation method thereof. Background technique [0002] The main components of traditional seedling-raising substrates are peat and peat, which are recognized as ideal cultivation substrates in the world. However, as it is used in large quantities year by year, its negative effects on society and the ecological environment are becoming more and more obvious. As a non-renewable resource, over-exploitation will seriously affect the balance of the ecosystem. Therefore, according to the resource situation in Hexi area, it is urgent to develop a more effective, more economical and more environmentally friendly seedling substrate. [0003] Bacteria chaff, animal manure and oxytetracycline dregs have been extensively studied and applied because they contain a large amount of organic matter and nutrients, and their effective use can ...

Problems solved by technology

For example, Chinese patent CN101433176 discloses a seedling substrate and its preparation method using mushroom dregs as the main raw material. Slag replaced peat, but vermiculite and perlite in the traditional matrix formula were used, which was inconvenient and costly

Chinese patent CN103342596 discloses a tomato seedling substrate made of paper mud, mushroom dregs and sand. Although the cost is saved, the paper mud has a long maturity cycle and has a single nutritional component

Chinese patent CN102850128 discloses a seedling-raising substrate made of corn stalks, cow dung, fungus residue, perlite and EM culture solution. The substrate has balanced nutritional components, utilizes agricultural waste resources, and can be reused. Water retention performance, permeability, and the influence of the substrate on the quality of seedlings, and the cost is high
