Description
Technical Field
The invention belongs to the technical field of artificial desert afforestation, and particularly relates to a root repairing and protecting agent for improving the survival rate of desert afforestation and application thereof.
Background
Afforestation, Chinese greening and ecological environment improvement are basic national policies of China and are necessary routes for building ecological civilization; drought and soil impoverishment are key factors influencing forestation, and in order to improve the survival rate of forestation, forestry technicians adopt various forestation combination technologies. The slurry dipping of the seedling root system is a common root system moisturizing method in forestry production, and is a measure for reducing the evaporation of root system water in the process of temporary planting and transportation after seedlings are lifted from a nursery. The common method is to stir common garden soil and water into slurry to dip the roots, so that a slurry layer is formed on the surface of the root system to reduce the evaporation of water of the root system, and a small amount of water-retaining agent, rooting powder and phosphate fertilizer are also added into the slurry. However, the slurry formed by common soil has weak adhesion, and has the problems of uneven slurry dipping, easy drying and falling and the like, so that the protection and afforestation effects on the root system are relatively poor, and the survival rate of a plurality of seedlings is influenced by water loss in the temporary planting and transportation processes.
At present, the disclosed root-protecting agent is mostly obtained by directly mixing a polymer resin water-retaining agent, hormone and a chemical fertilizer, and commonly used materials comprise water-retaining agent, aspirin, potassium dihydrogen phosphate, sodium humate, ABT rooting powder, sodium fulvate and the like. Although the root protecting agent can provide a certain moisturizing effect in the seedling transportation process, the moisturizing effect is still not ideal, and the moisturized seedlings can lose water and nutritional ingredients, so that the survival rate of the seedlings is low, the growth condition of the surviving seedlings is poor, and the production and use cost is high.

The invention provides a root repairing and protecting agent for improving the survival rate of desert afforestation, aiming at solving the technical problem that the survival rate of seedlings is influenced by water loss in the temporary planting and transportation processes due to poor protection effect of seedling roots, so as to solve the problems of difficult slurry adhesion, moisture preservation and fertilizer preservation in production, improve the survival rate of the desert afforestation seedlings and reduce the afforestation cost.
The second purpose of the invention is to provide the application of the root repairing and protecting agent.
The purpose of the invention is realized by the following technical scheme:
a root repairing and protecting agent for improving desert afforestation survival rate is composed of the following raw materials in parts by weight:
100-120 parts of natural sodium bentonite mineral powder, 150-160 parts of humic acid mineral powder and 2-3 parts of carbendazim wettable powder.
Preferably, the fineness of the natural sodium-based bentonite ore powder is 120-125 meshes, and the fineness of the humic acid ore powder is 100-120 meshes.
Preferably, the carbendazim wettable powder has an effective component content of more than 50%.
The application of the root repairing and protecting agent in desert forestation is provided.
Further, the root repairing and protecting agent is added with 1000-1200 parts by weight of water and stirred into viscous slurry, the root of the bare-root nursery stock is uniformly dipped with slurry 1-2mm thick immediately after the nursery stock is dug, and the nursery stock is transplanted according to a conventional method.
The humic acid mineral powder in the repairing root-protecting agent contains various active functional genes, so that the activity of catalase and polyphenol oxidase in the nursery stock can be enhanced, the physiological metabolism is stimulated, and the growth and development are promoted; the method can stimulate the division and growth of the cells of the extreme meristematic tissue of the root system, so that the seedlings have quick rooting, more roots, increased root amount and elongated root system, and the water and nutrient absorption capacity of the seedlings is enhanced; the opening strength of the air holes of the plant leaves is reduced, and the transpiration of the leaf surfaces is reduced, so that the water consumption is reduced, the water condition in the plant body is improved, the normal growth and development of crops under the drought condition are ensured, and the drought resistance is enhanced. The carbendazim wettable powder is a broad-spectrum bactericide, has a control effect on diseases of seedling roots caused by fungi, can effectively control the infection of the fungi in soil to the injured seedling roots, and enhances the disease resistance of the seedlings. The natural sodium bentonite is used as a main material, has the characteristics of water absorption, cohesiveness and organic matter adsorption, has the structural characteristics of bonding all components and playing the synergistic effect of all compound substances, has the advantages of preserving soil moisture and improving the effective utilization rate of organic matters, phytohormones and the like, particularly has the adsorption force smaller than the osmotic pressure of vegetation root systems, and cannot adsorb water of the plant root systems back even after water loss.
The invention has the following beneficial effects:
the root repairing and protecting agent for improving the survival rate of desert afforestation, provided by the invention, can form a layer of protective film on the root system of the nursery stock, has strong adhesion, is not easy to fall off, prevents the nursery stock from losing water and nutrients due to bad weather, long-time storage, long-distance transportation and the like, has good water and fertilizer retention effects, and can improve the survival rate of the nursery stock transplanted after being dipped with roots to more than 95%; the root repairing and protecting agent has the advantages of easily available raw materials, low cost, simple processing, no toxicity, no harm, no environmental pollution and convenient popularization and use.
