Technical Field

The invention belongs to the field of organic fertilizers, and particularly relates to a high-yield rice biological fertilizer and a preparation method of the high-yield rice biological fertilizer.

Background

Rice is one of herbaceous rice genera, and is also the most prominent and longest kind of grain in the rice genus. Native to China and is one of the main grain crops in the world.

Biofertilizers are generally biological agents produced by biotechnology and having a specific fertilizer effect (or both fertilizer effect and stimulating effect) on crops, and the active ingredients of the biological agents can be specific living organisms, metabolites of the organisms or transformation products of substrates, and the like, and the organisms can be microorganisms, and can also be animal and plant tissues and cells. Biological fertilizers are important fertilizer sources in agricultural production, like chemical fertilizers and organic fertilizers.

In recent years, due to the unreasonable application of a large amount of chemical fertilizers and chemical pesticides, a large amount of non-renewable resources are consumed, the soil structure is damaged, the quality and the environment of agricultural products are polluted, and the healthy survival of human beings is influenced. Therefore, from the development trend of green agriculture and ecological agriculture advocated in modern agricultural production, the pollution-free biological fertilizer without polluting the environment will play an important role in future agricultural production.
