Crop Seedling Raising Substrate Prepared by Pure Straw Fermentation Solid Byproduct and Preparation Method

Abstract

The invention provides a crop seeding growing substrate prepared by utilizing solid by-products produced by pure straw fermentation. After the solid by-products produced by pure straw biomass fermentation are decomposed and fermented again, the decomposed and fermented solid by-products are washed with water until the conductivity of the by-products is less than or equal to 0.2 ms / cm, and auxiliary ingredients are added into the solid-by-products to obtain the crop seedling growing substrate; the volume ratio of the decomposed and fermented solid by-products to the auxiliary ingredients is 2-5:1. Raw materials of the crop seedling growing substrate are green and organic, do not contain antibiotic, and are extremely low in heavy metal content, rich in organic matters, high in nutrient substance content and good in physical and chemical properties; waste matters after straw fermentation can be fully utilized, and natural turf resources are saved. The invention further provides a preparation method for the crop seeding growing substrate.

Description

technical field [0001] The invention relates to a crop seedling-raising substrate, in particular to a crop seedling-raising substrate prepared by using pure straw fermentation solid by-products, and a preparation method thereof. Background technique [0002] my country's annual output of crop straw is about 700 million tons, ranking first in the world, equivalent to 353 million tons of standard coal, accounting for about 30% of the world's total straw. my country's annual crop straw resources account for nearly half of the biomass resources. For a long time, due to the impact of consumption concepts and lifestyles, my country's rural straw resources have been in a state of high consumption, high pollution, and low output. A considerable part of crop straws has been discarded or burned, and has not been rationally developed and utilized. The treatment and utilization of straw is one of the main resource and environmental problems faced by rural areas in our country, and it i...

Problems solved by technology

Usually, due to the large amount of pathogenic bacteria in the original soil, there will be dead seedlings and stiff seedlings during the seedling cultivation process, and the seedlings will carry pathogenic bacteria, which will be susceptible to diseases after colonization and growth, which will affect the healthy growth of crops

There is a lack of related patents on seedling raising substrates prepared by using pure straw biomass energy fermentation solid by-products as the main substrate material
