A kind of soil active agent and preparation method thereof

Abstract

The invention provides a soil activator and a preparation method thereof. In the method, the active ingredient, a mixture of nutrient elements, a binder and an activator are uniformly mixed to obtain a mixed powder, and then the mixed powder is added with water and stirred evenly to make a semi-wet state. The mixture is obtained by granulating and drying; wherein, the active ingredients are obtained by mixing rhizome residues removed during production and selection of angelica, astragalus and codonopsis. The invention has low production cost, simple preparation method, easy control and operation, strong adsorption capacity, good slow-release effect, no environmental pollution, can not only improve soil fertility, but also improve the utilization rate of fertilizer efficiency, and can quickly Improve soil activity, loosen soil, rebuild soil ecological balance, suitable for industrial production.

Description

Technical field [0001] The present invention relates to the field of soil improvement technology, in particular to a soil activator and a method of preparation thereof. Background [0002] Soil is an important component of the geographical environment, and at the same time is the material basis of agricultural production, and it is also the basic resource for the construction of the ecological environment, which is inseparable from human relations. China is a large agricultural country, in the process of crop growth, it is necessary to absorb a moderate amount of mineral nutrients from the soil to maintain its normal growth and development, and complete its life course. Among them, including a large number of elements such as nitrogen, phosphorus, potassium, medium elements such as calcium, magnesium, sulfur, trace elements such as iron, manganese, copper, zinc, molybdenum, boron and so on. Due to the limited mineral nutrient elements that the tillage soil can provide to the crop...

Problems solved by technology

[0003] However, due to the low content of soil organic matter, small soil porosity, and compact structure, long-term use of chemical fertilizers will damage the soil structure, cause serious soil compaction, reduce the ability to retain water and fertilizer, lead to weak soil activity, and the nutrient elements applied to the soil cannot be absorbed in time. Decomposition and absorption, deposition of harmful minerals, and gradual impoverishment of the soil texture. Plants grown on this land have low yields and are prone to various diseases. people's health

The year-by-year decrease in production forces farmers to add more chemical fertilizers in larger doses, thus forming a vicious circle, destroying the micro-ecological balance of the soil, causing further deterioration of the ecological environment, and making it more difficult to improve the vitality of plants

[0004] At present, common soil improvement materials mainly include minerals, natural and synthetic polymer materials, and beneficial microbial preparations, etc., but the disadvantages of these products are that their functions are relatively single, and they pay too much attention to improving soil fertilizer efficiency or soil microbial activity, while ignoring them. Improvement of soil water supply capacity, and lack of comprehensive regulation of multifunctional effects

[0005] Patent CN103274851B discloses a water-soluble microbial agent for improving the vitality of plants. It uses soybean protein, amino acids, fulvic acid, and trace elements as carriers, and is implanted into endophytic bacillus. Fermented for 48 to 60 hours, it mainly depends on the action of microorganisms to improve the soil environment, with a single function and limited activation of the soil
