Humic acid water-soluble fertilizer special for beans and preparation method and application method thereof

Abstract

The invention discloses a humic acid water-soluble fertilizer special for beans and a preparation method and application method thereof. The humic acid water-soluble fertilizer special for beans is made from, by weight, 12-18 parts of humic acid, 18-24 parts of diammonium phosphate, 12-16 parts of urea, 6-10 parts of monopotassium phosphate, 3-6 parts of calcium sulfate, 2-3 parts of boron sulfate, 2-3 parts of EDTA (ethylene diamine tetraacetic acid) zinc chelate, 2-3 parts of EDTA iron chelate, and 1-3 parts of gibberellin. The humic acid water-soluble fertilizer special for beans has the advantages that macro elements and trace elements are reasonably matched according to the fertilizer demand law of beans for growth and development; humic acid provides good effect on improving soil, maintaining soil health and the like; nutrition condition of soil is comprehensively considered; utilization rate of the fertilizer can be increased, nutrition can be absorbed faster, and the quality ofbeans is improved.

Description

technical field [0001] The invention belongs to the field of agriculture, and more specifically relates to a special humic acid water-soluble fertilizer for beans and a preparation method and application method thereof. Background technique [0002] Beans are rich in protein and are an important source of protein nutrition for humans and livestock. Some legumes such as soybeans, groundnuts, and square beans contain a lot of edible oils in addition to being rich in protein. The protein content of many bean seeds is between 20-40%, and a few can reach 40-60%. Its protein content is 2-3 times higher than that of cereals, and 5-10 times higher than that of potatoes. In addition, the stalks, branches, and leaves of beans are also rich in protein, usually up to 8-14%, while the protein in cereal stalks and leaves is only 4-6%, so the stalks and leaves of beans have higher nutritional value. Feed and good green manure. Fresh pods, seeds, stems and leaves also contain several vit...

Problems solved by technology

[0004] In view of the reasons for the low yield caused by improper ratio of nitrogen, phosphorus and potassium, lack of trace elements, etc., there are many types of fertilizers on the market, but there are few special ones, nitrogen, phosphorus, potassium, and the ratio of medium and trace elements is not much. In particular, humic acid is difficult to meet the needs of beans in the improvement of soil, soil continuous cropping obstacles and soil nutrient utilization efficiency. If the amount of application is increased, other elements will be wasted and the environment will be polluted.
