Composite biological agent used for replacing chemical fertilizers and pesticides and preparation method thereof

Abstract

For reducing the negative effects of chemical fertilizers and pesticides on grain production and natural environment, the invention provides a composite biological agent used for replacing chemical fertilizers. The use of the composite biological agent can effectively avoid many drawbacks caused by the use of chemical fertilizers and pesticides, and has the effect of increasing both production and income of grains. The composite biological agent comprises the following ingredients: 10-15 wt% of plant enzyme preparation, 0.5-1.5 wt% of composite trace elements, 15-25 wt% of zeolite, and 60-70 wt% of water. The preparation method is characterized by mixing in proportion and fermenting. The composite biological agent can increase the production capacity of grains, improve the grain quality, effectively save resource and protect the environment. The method has the advantages of simple operation, easy control of the parameters, and short period, and is benefit for popularization and application.

Description

Technical field: [0001] The invention relates to a composite biological preparation and a preparation method thereof. Background technique: [0002] For a long time, in order to solve the problems of food production and food security, many places have produced and used chemical fertilizers and pesticides in large quantities, which has played a huge role in increasing crop yields and ensuring my country's food security. However, the long-term and excessive application of chemical fertilizers and pesticides has caused relatively serious pollution to the environment and brought ecological threats. The contradiction between the use of chemical fertilizers and pesticides and food security is becoming increasingly urgent. [0003] According to the data of the State Environmental Protection Administration in 2006, the annual application of pesticides in my country has reached 1.32 million tons, of which highly toxic pesticides accounted for 70%; the application of chemical fertili...

AI Technical Summary

Problems solved by technology

Crops are just like people, overeating is not only bad for growth, but also bad for health

There are two main consequences of excessive fertilization causing damage to crops: one is easy to lodging, once lodging occurs, it will inevitably lead to a reduction in grain production; Infested by pests and diseases, and then increase the amount of pesticides to eliminate pests and diseases, which directly threatens the safety of food

[0006] 2. Aggravate environmental pollution

Excess fertilizers will seep into the shallow groundwater within 20 meters, increasing the nitrate content in the groundwater

[0007] 3. Waste a lot of scarce resources

This kind of hazard often takes a long time to accumulate before showing symptoms, and it is not recognized by people; it enters the human body through the enrichment of the food chain, and it is difficult to detect in time. Therefore, it is generally not taken seriously by people. Therefore, such hazards are more dangerous

[0010] 2. Harm to the ecological environment

Coupled with the frequent use of pesticides, pests have developed resistance to pesticides, leading to an increase in the frequency and dosage of pesticides, increasing environmental pollution and ecological damage, thus forming a vicious circle of pesticide abuse
