Application Technology of EM Bacteria in High-Quality Rice Production
In recent years, China's grain output has been greatly increased, but it also faces the contradiction of severe environmental pollution and low quality of agricultural products. Long-term unreasonable application of chemical fertilizers has become one of the important factors that waste resources, pollute the environment, increase production costs, and affect the quality of agricultural products. With the improvement of human environmental protection and health awareness, the demand for pollution-free food is also increasing day by day. Therefore, in agricultural production, it is imperative to develop new biological organic fertilizers to reduce or even eliminate chemical fertilizers and produce high-yield, high-quality, and efficient agricultural products.
