Problems solved by technology

This invention can provide more comprehensive nutrition for crops, solve the problem of reducing waste molasses discharge pollution, the process is relatively simple, and is suitable for small-area irrigation or large-area drip irrigation; however, the organic liquid fertilizer has a low nutrient element content and a large application amount. It is usually used in conjunction with a certain amount of chemical fertilizers, and it is very inconvenient to irrigate farmland without a drip irrigation system

Abstract

The invention provides a water-soluble organic / inorganic compound fertilizer prepared by molasses fermentation liquor. The water-soluble organic / inorganic compound fertilizer is prepared by the following raw materials in percentage by weight: 30 to 75% of water-soluble nitrogenous fertilizer, water-soluble phosphatic fertilizer and water-soluble potash fertilizer, 0.5 to 5% of biological bacterium and the balance of 1 molasses fermentation liquor, wherein the molasses fermentation liquor is 45 to 95% molasses fermentation liquor. The preparation method comprises the following steps: pouring the molasses fermentation liquor into a fermenting tank; adding the biological bacterium; fermenting for 30 to 40 hours at 10 to 40 DEG C; removing colloid in the fermentation liquor; inactivating at high temperature; precipitating and then filtering to remove insoluble substance; adding the water-soluble nitrogenous fertilizer, the water-soluble phosphatic fertilizer or the water-soluble potash fertilizer to the fermentation liquor; granulating; and drying to obtain the finished product. The water-soluble organic / inorganic compound fertilizer provided by the invention is convenient to use, higher in nutrient element content, low in cost and remarkable in yield increasing effect.

Description

technical field [0001] The invention relates to the technical field of making fertilizer by using molasses fermentation liquid, in particular to a water-soluble organic-inorganic compound fertilizer made by using molasses fermentation liquid and a preparation method thereof. Background technique [0002] The survival of plants depends on the land, and fertilizer is the food of plants. Plants need a lot of nutrients to promote their rapid growth during the growth process. Different soils have certain effects on the growth of crops, which requires effective soil improvement. Existing fertilizers for soil improvement can only see the impact of fertilizers on crops, but cannot effectively improve the soil. Most of the soil is compacted due to the use of chemical fertilizers, and the poor soil is not harvested or harvested due to unreasonable fertilization. [0003] Due to the combination of the characteristics of organic fertilizer and inorganic fertilizer, organic-inorganic c...
