Description
Technical Field
The invention belongs to the technical field of seedling transplantation, and particularly relates to a mineral root dipping agent for sand excavation of large and medium-diameter seedling transplantation and application thereof.
Background
At present, ornamental big trees are needed in all aspects of the garden industry, and transplanting the big trees to parks, districts, roadways, squares and the like is an essential important step for landscaping. However, in arid regions in the northwest of China, due to drought climate in greening planting seasons, the survival rate of seedlings is low, and particularly, soil balls cannot be carried or are easy to disperse when seedlings are dug in nursery gardens in sandy regions. In the process of regulating and transporting the nursery stocks, the root systems and the branches are exposed to the sunlight for a long time and blown to the sun, so that the nursery stocks lose water, and the activity of the root systems is lost. The existing research results show that 80% of capillary roots of bare-rooted seedlings naturally stand for 4 hours under the drought conditions in spring, autumn and arid regions can be dried up and lose water, which undoubtedly increases the death risk of the seedlings, because 80% of water and inorganic salt provided by soil for the growth of trees are completed by the capillary roots. Therefore, in order to improve the survival rate of the planted seedlings, the most important is to keep the root system from withering and losing water as much as possible in the process of allocation and transportation.
The existing method for transplanting the large and medium diameter-grade nursery stocks is to improve the survival rate by lifting the seedlings with soil balls to protect fibrous roots; the seedlings are usually heeled in by bare-rooted seedlings firstly and then dipped in slurry to keep the water loss of the root system in long-distance transportation and reduce death, and the measures have high labor intensity and poor moisturizing effect, and the large seedlings often scatter soil balls after long-distance transportation; the seedling slurry keeps the water difference and the root system loses water and dies.
Disclosure of Invention
The invention provides a mineral root dipping agent for transplanting large and medium-diameter nursery stocks in sandy land, aiming at solving the technical problem that the survival rate of the nursery stocks is influenced by water loss in bad weather, temporary planting, transportation and after planting due to poor protection effect of the root systems of the bare-root nursery stocks, solving the problems of poor slurry adhesion, moisture preservation and fertilizer preservation effects in the transplanting process and improving the transplanting survival rate of the large and medium-diameter bare-root nursery stocks in sandy land.
The second purpose of the invention is to provide the application of the mineral root dipping agent.
The purpose of the invention is realized by the following technical scheme:
a mineral root dipping agent for transplanting large and medium-diameter nursery stocks dug in sand is composed of the following raw materials in parts by weight:
140 parts of natural sodium bentonite mineral powder, 90-100 parts of potassium fulvate mineral powder, 4-6 parts of polyacrylic acid sodium salt resin and 1-2 parts of microbial agent.
Preferably, the fineness of the natural sodium bentonite mineral powder is more than 125 meshes; the fineness of the potassium fulvate mineral powder is more than 100 meshes.
Preferably, the microbial agent is selected from more than two of bacillus subtilis, bacillus amyloliquefaciens, bacillus terrae, bacillus megaterium, beauveria bassiana and metarhizium anisopliae.
The mineral root dipping agent is applied to the transplanting of large and medium-diameter bare-root nursery stocks dug in sand.
Further, adding 1000 parts by weight of water into the mineral root dipping agent, stirring to form viscous slurry, uniformly dipping the roots of the large and medium-diameter bare-root nursery stocks into slurry with the thickness of 2-3mm while lifting the seedlings, and transplanting according to a conventional pruning protection method for large trees.
The potassium fulvate in the mineral root dipping agent can adsorb, exchange and activate a plurality of mineral elements in soil, so that the effectiveness of the fertilizer is greatly increased, the nutritional condition of the nursery stock is improved, insoluble phosphorus in the soil is converted into effective phosphorus, the conversion of organic phosphorus and inorganic phosphorus in the soil is promoted, the moving distance of the phosphorus in the soil is increased, the development of the root system of the nursery stock is stimulated, the nursery stock is promoted to grow roots quickly, secondary roots are more, the root amount is increased, the root system is elongated, and the capability of the nursery stock for absorbing water and nutrients is increased; through the absorption of the plant roots, the plant cell physiological metabolism is stimulated, which is particularly obvious in the aspects of increasing the respiration intensity and the photosynthesis intensity, stimulating the overground part of the plant to show vigorous growth, high plant height, strong stems and the like; the soil has high organic matter content, provides an excellent environment for beneficial microorganisms, and the beneficial population gradually develops into dominant population, inhibits the growth of harmful germs, and greatly reduces diseases, particularly the occurrence of soil-borne diseases because the plants grow robustly and have enhanced disease resistance due to the excellent soil condition. The sodium polyacrylate resin has a strong water retention function and provides sufficient water for the nursery stock; the microbial inoculum can prevent and treat the infection of the damaged root system of the nursery stock and has the function of disinfecting the soil in a humid environment. The natural sodium bentonite has the characteristics of water absorption, cohesiveness and organic matter adsorption, the structural characteristics of the natural sodium bentonite can enable all components to be bonded together and exert the synergistic effect of all compound substances, the natural sodium bentonite has the advantages of preserving soil moisture, promoting the growth of roots, improving the effective utilization rate of organic matters, auxin and the like, particularly can continuously and slowly release water and nutrient components, and is beneficial to the repair, protection and development of roots.
The invention has the following beneficial effects:
the mineral root dipping agent for transplanting the large and medium-diameter bare-root nursery stocks can form a layer of protective film on the root systems of the nursery stocks, has strong adhesion and is not easy to fall off, prevents the nursery stocks from losing water and nutrients due to bad weather, long-time storage, long-distance transportation and the like, and has good water and fertilizer retention effects; after the planting, the growth of root systems is promoted, the restoring force and the regeneration force of branches and leaves are improved, and the growth is vigorous; the survival rate of the seedlings after root dipping and transplanting can be improved to more than 95 percent; the mineral root dipping agent has the advantages of easily available raw materials, low cost, simple processing, no toxicity or harm, no environmental pollution, and convenient popularization and use.
