Abstract

The invention discloses a seedling culture substrate and a preparation method thereof. The seedling culture substrate comprises an expanded material, an organic substrate material and an inorganic substrate material, wherein the expanded material is expanded agricultural and forestry wastes. The sand shrub seedling culture substrate prepared from the agricultural and forestry wastes is a novel, efficient, safe, and environment-friendly seedling culture substrate, the survival rate of sand shrub seedlings can be improved, furthermore, the seedling culture period can be shortened, and the seedling culture substrate is suitable for mechanical transplantation.

Description

technical field [0001] The invention relates to a seedling-raising substrate, especially a sandy shrub seedling-raising substrate, and a method for preparing a sandy shrub seedling-raising substrate by utilizing agricultural and forestry waste. Background technique [0002] The utilization rate of agricultural and forestry waste resources in my country is only 35%, and the technical level of resource utilization is low. The use of agricultural and forestry wastes to prepare nutrient substrates is an important attempt to realize the development of circular economy. Puffing technology is a compound effect based on physical and chemical reactions. The working principle of the puffing equipment is that after the cut wet agricultural and forestry waste enters the extrusion chamber through the feeding screw, the mechanical energy is directly converted into heat energy, which instantly generates high temperature and high pressure, and suddenly drops at the discharge port to form s...
