Soil conditioner and preparation method thereof

Abstract

The invention discloses a soil conditioner and a preparation method thereof, belonging to the technical field of agricultural arable soil. In order to solve the technical problems, the technical scheme is as follows: the soil conditioner is composed of 8-12% of medical stone, 8-12% of opal, 8-12% of biomass thin ash, 60-70% of humic acid and 3-8% of activator. The preparation method comprises the following steps: 1. proportionally adding the five raw materials into a stirrer, stirring for 10 minutes, and uniformly conveying to an operating granulating disk through a belt conveyer; 2. spraying water into the granulating disk by an automatic measuring pump via a sprayer to perform aggregation and balling; 3. conveying the granules into a drying machine by a belt conveyer, and drying off the granules; 4. conveying the dried granules into a roller screen with the pore size of Phi 4.85 by a hopper elevator, and screening the granules; and 5. conveying the screened qualified product to a cooling machine, cooling, conveying to a full-automatic packing scale, weighing, packing and warehousing.

Description

technical field [0001] The invention relates to a soil conditioner and a preparation method thereof, belonging to the technical field of agricultural cultivated soil. Background technique [0002] At present, the application of inorganic fertilizers for many years in my country has caused the soil to harden and harden, the active components in the soil are reduced, the crop nutrient absorption is insufficient, the nutrient transport is restricted, and the continuous output of the land is affected. Now it is difficult to dig earthworms in the field. The soil is not only compacted but also more toxic. The biota in the soil is destroyed. The reason is that the organic matter in the soil in the cultivated land decreases, the inorganic minerals are deactivated, and the self-produced farmyard manure and straw returning to the field are limited. Contents of the invention [0003] In order to overcome the above technical deficiencies, the present invention provides a soil condi...
