Fruit and vegetable seedling substrate based on cassava dregs-sulfur acid adjustment and preparation method thereof

Abstract

The invention relates to a fruit and vegetable seedling substrate based on cassava dregs-sulfur acid adjustment and a preparation method thereof; the fruit and vegetable seedling substrate includes the components by the mass percentage: 40-80% of cassava dregs, 20-40% of thoroughly decomposed straw, 0.01-5% of a sulfur acid-adjusting agent, 0.1-8% of a buffering agent, 0.01-5% of a chelate compound, 0.05-1% of a microbial preparation and 0.01-2% of medium-trace element slow-release fertilizers. The structure is reasonable, and the method is advanced and scientific; according to the preparationmethod, the prepared fruit and vegetable seedling substrate has physical, chemical and biological properties similar to mature soil or natural substrates, is low in cost and simple in process, and can replace mature soil or natural medium consumption in certain fields. The fruit and vegetable seedling substrate has great breakthrough in the technology of substrate production and waste resource utilization, and has significant innovation.

Description

technical field [0001] The invention relates to a vegetable and fruit seedling raising substrate based on cassava residue-sulphur-adjusted acid and a preparation method thereof, belonging to the field of resource utilization of solid waste. Background technique [0002] Vegetable and fruit seedling substrate is a kind of artificially synthesized seedling raising material with functions similar to natural soil. The synthesis of vegetable and fruit seedling substrate can be formulated according to people's wishes and purposes, so that it can realize the function of natural soil. At present, the vegetable and fruit seedling substrate is widely used in the fields of vegetable and fruit seedling cultivation and soilless cultivation in agricultural production. Most of the preparation of vegetable and fruit seedling substrates is made of solid waste resources, such as cassava residues, crop straws, poultry and livestock manure, etc., but generally do not carry out acid adjustment ...

AI Technical Summary

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.
