A kind of cucumber seedling raising substrate and preparation method thereof

Abstract

The invention discloses a cucumber seedling substrate. The cucumber seedling substrate is prepared from, by weight, 1.5-2.5 parts of biogas dregs, 4-6 parts of chicken manure, 35-45 parts of biological carbon inoculant, 1.5-2.5 parts of straw powder and 1 part of perlite. The preparing method comprises the steps of taking components by weight part and mixing evenly the components through a roller. According to the cucumber seedling substrate, no grass carbon is adopted at all, therefore, the problems that grass carbon is expensive and is non-renewable in resource are solved, meanwhile the problem that large biogas residues pollute environment and an environment pollution problem brought by random stacking and arbitrary firing of corn and wheat straw are solved, and the cucumber seedling substrate can effectively maintain living and life environment of people, is beneficial to cycle development of agricultural economy, and has remarkable economic and social benefits. The use of the cucumber seedling substrate can effectively promote the growth of cucumber root systems, meanwhile is beneficial to reducing occurrence of soil-borne diseases, reduces the use of chemical agents, and facilitates the production of green vegetables.

Description

technical field [0001] The invention belongs to the technical field of soilless cultivation, and in particular relates to a substrate for cultivating cucumber seedlings and a preparation method thereof. Background technique [0002] With the rapid development of the facility vegetable industry, large-scale, intensive and professional seedling bases are developing rapidly. Whether the vegetable seedlings are healthy or not is not only related to the health status, disease resistance, product quality, yield and income of the growers after planting. , and can affect the healthy development of the entire vegetable industry, so the seedling substrate is a necessary choice for the growth and development of seedlings, and its reasonable choice becomes the premise to ensure the healthy development of the vegetable industry. [0003] Biogas residue is a residue of biogas, which contains rich nutrients such as N, P, K, organic matter, humic acid, biologically active substances, trace ...

AI Technical Summary

Problems solved by technology

[0005] At present, peat is an indispensable raw material in the substrate of vegetable seedlings at home and abroad, and the proportion in the substrate formula can account for about 30-50%. Peat generally comes from wetlands, and the reserves are limited. Excessive exploitation of peat will damage the wetland ecosystem. balance wreaks havoc

The uneven and non-renewable distribution of peat resources will greatly increase the cost of seedlings when used in seedling substrates
