Vegetable and fruit seedling raising substrate based on mushroom residue and sulfur used for acid adjusting and preparation method of substrate

Abstract

The invention relates to a vegetable and fruit seedling raising substrate based on mushroom residue and sulfur used for acid adjusting and a preparation method of the substrate. The substrate comprises the following materials in percentage by mass: 20-60% of mushroom residues, 40-60% of decomposed straw, 0.01-8% of a sulfur acid-regulating agent, 0.1-5% of a buffering agent, 0.01-5% of a chelate,0.05-1% of a microbial agent and 0.01-2% of a secondary and micro-element slow-release fertilizer. The substrate is convenient for use, the method is advanced and scientific, and the vegetable and fruit seedling raising substrate prepared by the method has similar physical, chemical and biological properties of mature soil or a natural substrate, low costs and a simple process, and can replace consumption of the mature soil or the natural substrate in a certain field. The method has a great breakthrough in technology of substrate production and waste recycling, and has remarkable innovativeness.

Description

technical field [0001] The invention relates to a vegetable and fruit seedling raising substrate based on mushroom residue-sulfur acid adjustment and a preparation method thereof, belonging to the field of solid waste resource utilization. Background technique [0002] Vegetable and fruit seedling substrate is a synthetic seedling material with functions similar to natural soil. The synthesis of vegetable and fruit seedling substrate can be formulated according to people's wishes and uses, so that it can realize the function of natural soil. At present, vegetable and fruit seedling substrates are widely used in the fields of vegetable and fruit seedlings and soilless cultivation in agricultural production. Most of the preparation of vegetable and fruit seedling substrates use solid waste resources, such as mushroom residue, crop straw, livestock manure, etc., but generally do not carry out acid adjustment treatment, but use the natural pH of raw materials, often over-alkali...

Problems solved by technology

Due to the popularization of coal, electricity and natural gas and the abundance of various industrial products in China in the past two decades, the demand for straw in rural areas has decreased, and the disposal of a large amount of straw has become a serious social problem. Although it is prohibited by law, farmers in many places still directly Burning straw in the fields will cause air pollution, fires, and the failure of planes to take off and land normally, posing a serious threat to people's lives and property.
