Cleating trace element containing microbial fertilizer and preparation method thereof

Abstract

The invention relates to a cleating trace element containing microbial fertilizer and a preparation method thereof. The cleating trace element containing microbial fertilizer is prepared through the following raw materials in parts by weight: 0.3-2 parts of cleating trace element, 3-15 parts of compound microorganism bacterium agent, 9-45 parts of turf, and 3-17 parts of surfactant, wherein the cleating trace element includes zinc sulfate, ferrous sulfate, borax, copper sulfate, manganese sulfate and sodium molybdate; the compound microorganism bacterium agent comprises photosynthetic bacteria, azotobacter chroococcum, bacillus mucilaginosus and bacillus dephosphoria based on the volume ratio of 1: 2: 2: 2. With the adoption of the microbial fertilizer, the problems of low permeability, poor fertilizing and water preserving performance and high chemical fertilizer consumption caused by soil hardening in the prior art can be effectively solved; the absorption and utilization of crops to major elements such as nitrogen, phosphorus and potassium, and trace elements such as iron, manganese and copper can be obviously prompted. Therefore, the crop growing is improved; the crop quality is improved; the crop yield is increased; and as a result, the fertilizer is an ideal fertilizer for green agriculture and organic agriculture.

Description

technical field [0001] The invention belongs to the field of fertilizers, and in particular relates to a microbial fertilizer containing chelated trace elements and a preparation method thereof. Background technique [0002] Agriculture is the basic industry of our country and has always occupied an important position in the national economy. Over the past 30 years, my country's grain production has achieved remarkable growth. However, while increasing food production, long-term excessive use of chemical fertilizers has also brought about problems such as environmental pollution, soil compaction, soil fertility decline, ecological deterioration, and decline in the quality of agricultural products. In addition, the excessive use of chemical fertilizers also reduces the utilization rate of chemical fertilizers, resulting in increased agricultural costs and reduced production efficiency. At present, the utilization rate of chemical fertilizers in my country is about 30%, while...

AI Technical Summary

Problems solved by technology

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a microbial fertilizer containing chelated trace elements and a preparation method thereof. The problem of weak fertilizer water retention capacity and high chemical fertilizer consumption can significantly promote the absorption and utilization of macronutrients such as nitrogen, phosphorus, and potassium, and trace elements such as iron, manganese, and copper, so as to promote crop growth, improve crop quality, and increase crop yield.
