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

Abstract

The invention discloses a method for preparing a special insect preventing type bio-fertilizer for a leafy vegetable, and belongs to the technical field of bio-organic fertilizers. According to the method, the bio-fertilizer is prepared by taking the following components as raw materials: urea, triple superphosphate, potassium sulphate, pyrethrum powder, humic acid, thuringiensis bacillus powder, serratia marcescent powder, polyaspartic acid, and EDTA chelated microelements. Compared with the prior art, the bio-fertilizer prepared by the method can promote the growth of crops and improve the quality of the crops, and can also kill injurious insects such as threadworms and fly maggots in soil.

Description

[0001] This application is submitted by the applicant Anhui Laimjia Fertilizer Co., Ltd. "The name of the invention is: a special biological fertilizer for insect-proof leafy vegetables and its preparation method. The application date is August 19, 2014, and the application number is: 2014104074362" divisional application. technical field [0002] The invention relates to the technical field of bio-organic fertilizers, in particular to a method for preparing special bio-fertilizers for insect-proof leafy vegetables. Background technique [0003] 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. a...
