Preparation method, product and application of soil remediating active organic fertilizer

Abstract

The invention discloses a preparation method, a product and application of a soil remediating active organic fertilizer. The preparation method provided by the invention comprises the following steps: hydrolyzing caked dregs by using an enzyme to obtain the caked dregs containing active free amido acids, and then carrying out mixed fermentation on hydrilla soil, yellow bran, shell powder, bone meal, shrimp and crab shell meal by use of ferment bacteria to obtain organic fermented materials; finally, blending the caked dregs containing the active free amido acids with the organic fermented materials and adding a soil enzyme, thereby obtaining the active organic fertilizer for soil remediation which is up to the national microbial fertilizer standards. The soil remediating active organic fertilizer provided by the invention is capable of improving the fertilizer utilization rate and the percent conversion of crop nutrients; according to practices, the utilization rate of the fertilizer can be increased by 1.5-1.8 times, and therefore, the effects of over production, quality improvement, yield increase and good harvest can be achieved. Importantly, the product of the preparation method provided by the invention is capable of effectively improving the soil hardening condition, recovering the gas-solid-liquid ratio of the arable soil, forming the granular structure, improving the water retention capacity, proliferating the beneficial bacteria and activating soil.

Description

technical field

[0001] The invention relates to a soil repairing active organic fertilizer and a preparation method thereof, in particular to a soil repairing active organic fertilizer for improving soil and controlling compaction and a preparation method thereof. The invention belongs to the fields of agricultural environmental protection and planting fertilizer manufacture. Background technique

[0002] In recent decades, various reasons have formed the habit of partial application of chemical fertilizers in agricultural planting, resulting in soil acidification, soil compaction, quality degradation, insufficient organic matter content, water and fertilizer retention, and decreased air permeability. According to the survey, the polluted cultivated land in our country is as many as 1.5 billion mu, 32.5 million mu is irrigated with sewage, and 2 million mu of farmland is occupied and destroyed by solid waste, accounting for more than 10% of the cultivated land area.
