Yingguangbao microbial fertilizer, non-toxic and harmless, non-toxic, is a biological organic fertilizer, for all agricultural plants, crops, vegetables, Chinese herbal medicine, flowers, fruit trees, tea can be used, the use method is simple: can be the original solution of seed dressing, with water leaf spray, drip irrigation, root irrigation, etc., the use and non-use of crops comparison, the effect is obviously good, Tencent, Youku, etc. **Tens of thousands of different crops yield increase effect**You can refer to it.

The microbial species that degrade pesticides in the environment, the mechanism of microbial degradation of pesticides, the factors affecting microbial degradation of pesticides under natural conditions, and the new technologies and methods for the study of microbial degradation of pesticides are reviewed. This paper argues that in the study of microbial degradation of pesticides, attention should be paid to the degradation process of pesticides by microorganisms in the natural state, and the separation and construction of a composite system composed of natural microorganisms should be constructed, and the use of microbial composite systems for composting or applying compost to the polluted environment is an effective method to eliminate pesticide pollution.

Microbial biodegradation of pesticides degrading pesticides The first "green revolution" that appeared in the 60s of the 20th century has made significant contributions to human food security, among which pesticides, as one of the main technologies, have played an important role in ensuring the increase of food production. Because pesticides have the advantages of low cost, quick effect, time and labor saving, they are widely used in agricultural production in countries around the world, but the excessive use of pesticides has a serious negative impact. In 1985 alone, the world's pesticide production was more than 2 million tons [1]; In China, the output of pesticides in 1990 alone was 10,000 tons [2], of which the amount of methamidophos was 60,000 tons [3].
Chemical pesticides are mainly synthetic biological exogenous substances, many pesticides themselves are toxic to humans and other organisms, and many types are stubborn compounds that are not easy to biodegrade. Pesticide residues are difficult to degrade, people use pesticides to prevent diseases, insects and weeds at the same time, but also make food, vegetables, melons and fruits and other pesticide residues exceed the standard, serious pollution, and at the same time bring harm to non-target organisms, pesticide poisoning incidents and occupations caused every year.

No matter which manufacturer produces microbial agents, they cannot be mixed with pesticides and fungicides!
The reasons are as follows: 1. The most important thing for microbial agents is bacteria, and insecticides and fungicides can completely kill the bacteria in the microbial agents, resulting in no effect on microbial agents!
2. It cannot be used together with large chemical fertilizers or chemical fertilizers with excessive salinization, which will also cause the bacteria in the microbial agent to survive!
How to use biological fertilizer with the best effect, how to fertilize biological fertilizer, biological fertilizer manufacturers.
Because biological fertilizer contains a large number of biological agents, with the help of biological bacterial activities, it can not only improve the structure of the soil and increase the content of various elements in it, but also bring the effects of potassium dissolving, phosphorus release and nitrogen fixation. After the biological bacteria fertilizer is applied to the soil, the biological bacteria proliferate quickly, forming a group advantage to decompose the nitrogen, phosphorus and potassium that are fixed in the soil and cannot be absorbed and utilized by plants, and fix the free nitrogen in the air for plants to absorb and utilize. Biological fertilizer can also help crops to take root, emerge and mature earlier, and will make crops resistant to stress, which can effectively resist disease, drought and lodging.
Answer: (1) Improve soil fertility. This is the main effect of biofertilizers, such as various autogenous, combined or symbiotic nitrogen-fixing biofertilizers, which can fix nitrogen in the air and increase nitrogen content in the soil; A variety of microorganisms that decompose phosphorus and potassium minerals, such as silicate bacteria, can decompose potassium feldspar, mica and phosphate rock in the soil, so that the insoluble phosphorus and potassium in them are effective. >>>More
Plot Selection:
The soil is moist, acidic soil, mixed with well-decomposed and fermented poultry manure, applied on cloudy days or in the evening, and ploughed as soon as possible after application. >>>More
Microbial fertilizer is developed according to the principles of soil microecology, plant nutrition, and the basic concepts of modern "organic agriculture". Microbial fertilizer is a product that causes crops to obtain specific fertilizer effects due to the life activities of microorganisms, and is a kind of fertilizer used in agricultural production. It has a history of nearly 50 years in China, from rhizobia agent - bacterial fertilizer - microbial fertilizer, from the name of the evolution has explained the gradual development process of microbial fertilizer in China.
