Abstract

The invention discloses a method for preparing a nematode-killing microbial organic fertilizer, which comprises the following steps of: (1) grinding agricultural organic waste, adding water and a composting bacterial agent, uniformly mixing, keeping the temperature to be between 55 and 65 DEG C, and composting for 15 to 20 days; (2) adding the water and the composting bacterial agent into livestock and poultry excrement, uniformly mixing, keeping the temperature to be between 55 and 65 DEG C, and composting for 15 to 20 days; and (3) mixing materials obtained in the step (1) and the step (2),adding microbial composite liquid, chelating trace elements and humic acid, and uniformly mixing to obtain the nematode-killing microbial organic fertilizer. Environmental pollution is reduced, the content of organic matters and various trace elements in the produced organic fertilizer is high, the fertility-retaining capacity and buffer property of soil can be improved, the nutrient-deficiency symptom of crops can be obviously improved, the absorption of phosphorus and potassium by the crops is promoted, underground pathogenic bacteria can be prevented and killed, and a good living environment is created for the root systems of plants.

Description

technical field

[0001] The invention relates to the technical field of biological fertilizers, in particular to a method for preparing nematode-killing microbial organic fertilizers. Background technique

[0002] With the rapid development of the chemical industry, the production and application of various chemical fertilizers have been increasing, which has played an important role in promoting the development of agricultural production and made great contributions to solving the food problem in our country. However, with the continuous increase in the amount of chemical fertilizer application, the shortcomings of its application are gradually exposed, and the analysis is mainly manifested in the following aspects: 1. The utilization rate of fertilizer efficiency is low. At present, the utilization rate of nitrogen fertilizer in my country's chemical fertilizer field is only 15-40%, the utilization rate of phosphorus fertilizer is only 10-20%, and the utilization rate of po...
