Organic compound fertilizer and preparation method thereof

Abstract

The invention discloses an organic compound fertilizer and a preparation method thereof. The organic compound fertilizer is composed of the following components in parts by weight: 15-20 parts of human manure, 4-6 parts of stable manure and 12-18 parts of industrial vinasse material. The preparation method comprises the following steps: proportionally and thoroughly mixing the human manure, stable manure and industrial vinasse, and stirring into a sludgy fertilizer. The human manure is processed by the following steps: fermenting the human manure in a methane tank for 10 days, laying a layer of corn or haulm straws according to the volume ratio of 1:2 or 1:3, layering a layer of human manure, spreading lime water which accounts for 30 vol% of the straws and human manure, covering a 5cm-thick soil layer, and composting at high temperature. The organic compound fertilizer can enhance the activity of various saccharides and enzymes in the soil, enable the plough layer of the soil to be loose and porous, and promote the formation of the crumb structure, so that the soil has high water retaining capacity; and the organic compound fertilizer solves the problem of low contents of water fertilizers and organic matters in the soil due to abundant use of chemical fertilizers by human.

Description

technical field [0001] The invention relates to the technical field of organic and compound fertilizers, in particular to an organic compound fertilizer and a preparation method thereof. Background technique [0002] Since the reform and opening up, in order to increase the output of crops, people have used a large amount of or even excessive chemical fertilizers, resulting in low organic matter content in the soil, resulting in poor soil quality, soil surface structure, and soil compaction. When it rains, the seepage of the vertical soil layer between water flow is extremely weak However, the content of organic matter in the cultivated land will continue to decrease, which will affect the deterioration of the cultivated land, and the water content will decrease, which will reduce the water and fertilizer retention performance of the cultivated land, resulting in a gradual decrease in the content of water and fertilizer in the soil and the organic matter in the soil. Conten...
