Melon and fruit vegetable seedling growing substrate prepared through agricultural waste

Abstract

The invention relates to the technical field of fruit and vegetable seedling growing substrates, in particular to a melon and fruit vegetable seedling growing substrate prepared through agricultural waste. The seedling growing substrate is prepared from fermented straw, wormcast, bran, expanded perlite and composite expanded perlite according to the weight ratio of 3:1:3:1:0.1. A preparation method comprises the steps of preparation of the fermented straw, preparation of the composite expanded perlite and even mixing of all the components. Static composting and turning of different frequenciesare combined, all parameters of the fermented straw preparation process are controlled, and the preparation quality of the fermented straw is ensured. A small amount of composited expanded perlite isadded to improve the hydrophobicity of the expanded perlite, heat preservation and separation are carried out on melon and fruit vegetables, and the influence of the temperature difference on the seedling growing productive rate is avoided; the agricultural waste resources are reasonably utilized, the production cost is reduced, meanwhile, supply of cultivating nutrients is guaranteed, environment protection is achieved, and the problem that an existing cultivating substrate consumes non-renewable resources is solved.

Description

technical field [0001] The invention relates to the technical field of fruit and vegetable seedling raising substrates, in particular to a kind of fruit and vegetable seedling raising substrate prepared by using agricultural waste. Background technique [0002] With the development of vegetable production in the direction of standardization, scale and specialization, the way of raising vegetable seedlings in my country has gradually changed from traditional single-family soil cultivation to industrial soilless seedling cultivation, which saves land resources and greatly improves the efficiency of seedling cultivation. Seedling raising is an important technical link in the vegetable production process. The quality of seedlings directly affects the growth, yield and quality of vegetables. At present, the substrate of soilless seedlings is usually composed of peat, vermiculite, perlite and the like. [0003] Peat is rich in a variety of organic matter and minerals. It is an id...

AI Technical Summary

Problems solved by technology

However, my country's peat resources are limited, the geographical distribution is uneven, and long-distance transportation is difficult, which greatly increases the economic cost of raising seedlings. Moreover, peat is a non-renewable resource, and excessive exploitation will inevitably lead to resource depletion and damage the environment.
