Abstract
The invention discloses a preparation technical method of a barren soil conditioner for a mountain area of a plateau, which comprises the steps of mixing excess sludge of a sewage plant with organic wastes such as cow dung and kitchen waste, sequentially adding a bulking agent and a conditioning agent, adding two microbial agents such as compound bacillus and compound fungi into a mixture, carrying out primary fermentation composting for 12-16 d, timely adjusting air supply oxygenation intensity according to the condition of temperature rise of a pile body, controlling the primary fermentation temperature of the compost at 48-56 ℃, continuing post fermentation treatment, adding a arbuscular mycorrhizal accelerant into a composting product, and the prepared soil conditioner can effectively solve the problems of low organic matter content, mineral element deficiency, soil hardening, poor water storage and soil moisture preservation effects and the like of barren soil for the mountain area of the plateau.
Description
Technical Field
The invention belongs to the technical field of ecological environment restoration in mining areas and sustainable development of plateau agriculture, and particularly relates to a technical method for preparing a barren soil conditioner in a mountain area of a plateau.
Background
The Yun Guigao original region has strong chemical weathering and leaching effects, low soil fertility and prominent barrier characteristics of acid, viscosity and thinness, and restricts the sustainable development of the plateau special agriculture. According to the second national soil census data, most cultivated lands in China lack organic matters, total nitrogen and available phosphorus content, and the soil barren phenomenon is serious. Compared with plain areas, the mountain areas of the plateau have the characteristics of complex terrains, various climate changes and the like, the hydrothermal conditions of the soil of the mountain areas are obviously influenced, the formation and development of the soil are further influenced, and the differences of the slope of the terrains and the land utilization mode finally result in thin soil layers, easy scouring and erosion, poor water retention capacity and large ecological restoration difficulty of mountain bodies of the mountain areas. The main methods for improving the barren soil in the mountain area of the plateau are commonly used nowadays: the organic fertilizer or the soil conditioner is added, and a reasonable intercropping system is implemented, wherein the soil conditioner can provide nutrients, organic matters and the like for the soil, so that the soil humidity is increased, and the normal utilization of the soil is not influenced, thereby being widely applied.
At present, a plurality of soil amendments are developed aiming at saline-alkali soil, acid soil, heavy metal pollution and the like in the market, but the fertility level is uneven, and meanwhile, the problems of low organic matter content, unstable effect and high production cost exist. The prior patent CN113604224A provides a composite modifier for barren soil in mountain areas and a use method thereof, wherein the water-retaining agent, the organic fertilizer, the rice hull charcoal and the microbial agent are prepared into the composite modifier according to a proportion, the organic fertilizer is prepared by high-temperature aerobic fermentation of decomposed chicken manure, garden waste and vermiculite powder, bacillus subtilis, arbuscular mycorrhizal fungi, bacillus licheniformis, actinomycetes and biological enzymes are added, the prepared composite modifier is spread on the surface of barren soil, and the plant survival rate of a grass seed sowing mode can be increased by ploughing and loosening soil, so that the ecological landscape restoration effect in the mountain areas is improved. In the implementation process of the patent, polyacrylamide and sodium polyacrylate are directly added as water retention agents to improve the water retention and moisturizing capability of soil, and although the polyacrylamide and the sodium polyacrylate have good water solubility and good moisturizing effect, the polyacrylamide and the sodium polyacrylate are more applied to the field of water treatment to be used as water purification agents, and the potential risks of the barren soil improvement process such as soil particle adhesion, biotoxicity and the like are not clear. The soil conditioner with strong applicability, stable effect and proper selling price is developed to realize the quality improvement and the efficiency improvement of the barren soil, which is still the key content of the ecological environment restoration in the mountain area of the plateau and the focus of the sustainable development of agriculture.
Disclosure of Invention
The invention provides a preparation technical method of a barren soil conditioner for a mountain area of a plateau, which comprises the steps of uniformly mixing excess sludge of a sewage treatment plant with organic wastes such as cow dung and kitchen waste, adding a bulking agent, a conditioner and a compound microbial agent, carrying out main fermentation treatment on high-temperature compost, continuing post-fermentation treatment, reducing the water content of the heap to 36+/-2%, and adding a arbuscular mycorrhizal promoter into a compost product, wherein the obtained product is suitable for improving and conditioning barren soil for the mountain area of the plateau. The organic waste adopted by the technology contains rich protein, starch and polysaccharide components, and more rich organic matters are released during high-temperature composting so as to generate humus through Maillard reaction; the residual sludge is rich in nitrogen and phosphorus, and has good water and soil moisture preserving effects; the conditioner and the compound microbial agent are added into the composting system at the same time, and mineral element dissolution is promoted through the synergism of bacteria and fungi with good decomposition effect on silicate minerals. The prepared soil conditioner has high organic matter and mineral element content, good air permeability and good soil water storage and soil moisture preservation performance, can effectively relieve the problems of low organic matter content, nutrient element deficiency, soil hardening and the like of the plateau barren soil, and obviously improves the soil productivity.
The implementation steps of the invention are as follows:
(1) Mixing the excess sludge of the sewage plant with other organic solid wastes, adjusting the initial water content to 61-65%, sequentially adding a bulking agent, a conditioning agent and a microbial agent, carrying out primary fermentation treatment on the compost for 12-16 d, timely adjusting the air supply oxygenation strength according to the temperature rising rate of the compost, and controlling the primary fermentation temperature of the compost at 48-56 ℃;
(2) And continuing post-fermentation treatment for 15-20 d, controlling the water content of the pile body to be 34-38%, returning part of compost products to the compost mixture material in the main fermentation stage, blending the initial water content of the compost mixture material, and adding arbuscular mycorrhizal accelerant into the rest of compost products to obtain the product for improving and conditioning barren soil in mountain areas of the plateau.
