Soil activator and preparation method thereof

Abstract

The invention provides a soil activator and a preparation method thereof. The method includes the steps that firstly, an active ingredient, a nutrient element mixture, a binding agent and an activating agent are mixed evenly to obtain mixed powder, then water is added into the mixed powder, the mixture is stirred evenly to be made into a semi-wet mixture, and the semi-wet mixture is granulated anddried to obtain the soil activator, wherein the active ingredients are obtained by mixing rhizome residues removed in the production and selection process of angelica sinensis, astragalus membranaceus and codonopsis pilosula. The preparation method is low in production cost, simple in process, easy to control and operate, high in adsorption capacity, good in slow release effect, free of environmental pollution, capable of improving the soil fertility, capable of improving the utilization rate of fertilizer efficiency, capable of rapidly improving the soil activity, loosening soil and reconstructing soil ecological balance and suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a soil activator and a preparation method thereof. Background technique [0002] Soil is an important component of the geographical environment, the material basis of agricultural production, and the basic resource for ecological environment construction, which is inseparable from human beings. China is a large agricultural country. During the growth of crops, they need to absorb various mineral nutrients from the soil in order to maintain their normal growth and development and complete their life course. Among them, include macroelements such as nitrogen, phosphorus, and potassium, moderate elements such as calcium, magnesium, and sulfur, and trace elements such as iron, manganese, copper, zinc, molybdenum, and boron. Since the cultivated soil can provide limited mineral nutrients for crops to absorb during the crop growing season, people will choose various chemical ...

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
