Long-acting humic acid compound fertilizer and production method thereof

Abstract

The invention discloses long-acting humic acid compound fertilizer, which is prepared by the following raw materials: 260 parts of 98% of concentrated sulfuric acid, 100 parts of potassium chloride, 300 parts of 20% of phosphoric acid, 150 parts of humic acid, 10 parts of ammonium chloride, 10 parts of bactericide, 20 parts of magnesium powder and 20 parts of calcium powder. The invention further discloses a preparation method for the long-acting humic acid compound fertilizer. According to the long-acting humic acid compound fertilizer, the loss of fertilizer and water can be effectively controlled, the yield of crops can be increased, and the cost is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a long-acting humic acid compound fertilizer and a production method thereof. Background technique [0002] Since the founding of New China, as a major agricultural country, the types and quantities of chemical fertilizers have been increasing day by day, which has played a great role in increasing grain production. In the 1970s, farmers did not use chemical fertilizers, and the government promoted them; in the 1980s, there was a rush for chemical fertilizers, and the introduction of pesticides, farmers reduced the amount of organic fertilizers; in the 1990s, the input of chemical fertilizers increased, and soil pollution increased even more. In the late 1990s, farmers did not use bio-organic fertilizers, which led to a serious lack of trace elements in the soil, a large amount of chemical fertilizers and pesticides remained in the soil, and the gradual increase o...

Problems solved by technology

The super-intensive use of chemical fertilizers has further deepened the deterioration of long-term cultivated land such as compaction, salinization, and poor water loss and fertilizer retention during the fertilization process.
