China only needs one-fifth of the world's arable land to feed one-fifth of the world's population. Increasing the output per unit area and meeting the demand for increasing food is the need for sustainable agricultural development. Fertilizer is the "food" of plants. Microbial fertilizers, organic fertilizers and inorganic fertilizers constitute the whole of fertilizers and have different effects on crop growth. The application of organic fertilizer is an essential part of agricultural production. It is a traditional fertilization method in China for thousands of years. It can not only provide comprehensive nutrition for crops, promote crop growth, but also improve soil physical, chemical and biological properties, and mature soil. Fertilize the soil. The use of organic fertilizer alone can maintain soil fertility and a certain production capacity, but it is difficult to increase production per unit area and meet the needs of a growing population. Chemical fertilizers are rich in quick-acting nutrients and energy. Rational application of chemical fertilizers can greatly increase crop yields. It is essential to apply fertilizers at the current stage of sustainable agricultural development.
The new version of microbial fertilizer is defined as: “Is a product of a specific microbial organism, applied to agricultural production, through the life activities of the microbes contained therein, increasing the supply of plant nutrients or promoting plant growth, improving the quality of agricultural products and the agro-ecological environment.†A definition clearly states that microbial fertilizer is an organic biological organism, a new type of fertilizer. It not only provides crops with all kinds of nutrients necessary for growth, but also increases the activity of beneficial microorganisms in the soil, while overcoming the drawbacks caused by excessive application of fertilizers and unbalanced fertilization. Excessive application of chemical fertilizers will cause damage to natural ecology, such as increased nitrate content in the environment, secondary salinization of protected areas, destruction of certain soil structures, effects on the quality of vegetables and fruits, and finally the rate of return of fertilizers. Reduce and soil degradation.
Microbial fertilizers are also responsible for the transformation of soil organic matter into humus, increasing soil aggregate structure, improving water retention and fertilizer retention capacity, activating soil-solidified nutrients, and improving fertilizer utilization. At the same time, the beneficial microorganisms in the microbial fertilizer secrete various beneficial substances to the soil, such as growth stimulating hormone, indole acetic acid, gibberellin and various enzymes, thereby effectively promoting the transformation of nutrients, alleviating the occurrence of soil-borne diseases, and repairing the pollution. soil. Therefore, microbial fertilizer can be said to be an ideal fertilizer for green agriculture and organic agriculture, and has broad prospects for sustainable agricultural development.
