Description
Technical Field
The invention relates to a seedling substrate, in particular to a sand shrub seedling substrate, and relates to a method for preparing the sand shrub seedling substrate by using agricultural and forestry wastes.
Background
The utilization rate of agricultural and forestry waste resources in China is only 35%, and the technical level of the utilization of the resources is low. The preparation of nutrient substrates from agricultural and forestry waste is an important attempt to realize the development of circular economy. The puffing technology is a composite 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 cavity through the feeding screw, mechanical energy is directly converted into heat energy, high temperature and high pressure are generated instantly, and the spraying puffing is formed by suddenly dropping at the discharge port, so that the aims of curing and saccharifying are fulfilled. Due to the instantaneous sudden drop of the pressure, the agricultural and forestry waste expands in volume and becomes fluffy and soft, thus forming a flocculent structure. Has high adsorption performance, can greatly improve the water absorption and retention performance of the matrix, and is particularly suitable for the seedling culture of sandy shrubs. This is the novelty of the present invention. The novel, efficient, safe, green and environment-friendly sandy shrub seedling raising matrix is rarely reported at home and abroad.
The desertification land area of China is 172.12 ten thousand square kilometers, which accounts for 17.93 percent of the total area of the national soil, and the control of the sandy land (desert) becomes the key task of ecological construction of China. The method for controlling the sand by using the sandy shrubs as the live sand barriers has good application and popularization prospects. Facing to the severe ecological conditions of desert areas, the survival difficulty of the sand seedlings is high, and the maintenance cost is extremely high. If the seedling raising substrate required by the growth of the sandy shrubs can be developed, the standardization of desertification control materials and processes, the high efficiency and near naturalization of vegetation recovery and the mechanization of operation construction are realized, so that the desertification control efficiency and quality are improved, and the desertification control work is promoted to be transformed and developed towards the direction of mechanization, high efficiency and low cost.
