Problems solved by technology

Biological fertilizers can improve soil fertility, promote crop growth, improve crop quality, and can also antagonize pathogenic bacteria, prevent diseases and strengthen bacteria. For example, some biological fertilizers not only help crops to absorb mineral elements such as phosphorus, zinc and copper. It also has the function of enhancing crop water absorption and water retention to improve crop drought resistance, that is, water-retaining functional bio-fertilizers, but the current research on insect-resistant bio-fertilizers is still blank

Embodiment 1

[0038] A special bio-fertilizer for insect-proof leafy vegetables, parts by weight: 300 parts of urea, 295 parts of superphosphate, 220 parts of potassium sulfate, 40 parts of pyrethrum powder, 20 parts of humic acid, 40 parts of Bacillus thuringiensis powder, and Niusin sand 40 parts of Rhettella powder, 25 parts of polyaspartic acid, 20 parts of EDTA chelated trace elements.

[0039] The preparation method of the insect-proof type leaf vegetable special biological fertilizer of the present invention comprises the following process steps:

[0040] (1) Various raw materials such as 300 parts of urea, 295 parts of heavy superphosphate, 220 parts of potassium sulfate, 40 parts of pyrethrum powder, 20 parts of humic acid, 25 parts of polyaspartic acid, 20 parts of EDTA chelated trace elements, etc. The formula is measured and put into the mixing tank for mixing;

[0041] (2) Send the uniformly mixed raw materials to the crusher for crushing with the conveyor belt, and then send ...

Embodiment 2

[0046] A special bio-fertilizer for pest-proof leafy vegetables, parts by weight: 261 parts of urea, 325 parts of superphosphate, 240 parts of potassium sulfate, 50 parts of pyrethrum powder, 14 parts of humic acid, 35 parts of Bacillus thuringiensis powder, and Nienshi sand 35 parts of Rhettella powder, 30 parts of polyaspartic acid, 10 parts of EDTA chelated trace elements.

[0047] The preparation process is the same as in Example 1.

Abstract

The invention discloses an insect-proof special biological fertilizer for leafy vegetables and a preparation method thereof, belonging to the technical field of biological organic fertilizers. The parts by weight of its various components are as follows: 200-500 parts of urea, 200-500 parts of superphosphate, 150-350 parts of potassium sulfate, 20-60 parts of pyrethrum powder, 5-30 parts of humic acid, Bacillus thuringiensis Bacteria powder 20-50 parts, Serratia stickinii powder 20-50 parts, polyaspartic acid 10-50 parts, EDTA chelated trace elements 0-30 parts. Compared with the prior art, the invention can not only promote the growth of crops, improve the quality of crops, but also kill nematodes, fly maggots and other pests in the soil.

Description

technical field [0001] The invention relates to the technical field of bio-organic fertilizers, in particular to a special bio-fertilizer for insect-proof leafy vegetables and a preparation method thereof. Background technique [0002] The fertilization of leafy vegetables is mainly based on organic fertilizers, focusing on base fertilizers, topdressing fertilizers reasonably, controlling the amount of nitrogen fertilizer, prohibiting the application of nitrate nitrogen fertilizers, and at the same time fertilizing the soil to maintain the balance of soil fertility. Cabbage, lettuce, etc. have little accumulation of nitrate, while cabbage, amaranth, spinach, etc. are easy to accumulate nitrate. Therefore, leafy vegetables whose nitrate content seriously exceeds the standard will endanger human health. With the significant growth of China's economy and the integrated development of the global economy, and China's successful transformation from a "subsistence" society to a "w...
