Due to the use of a large number of inorganic fertilizers and chemical pesticides, soil residual pesticides are toxic, soil salinization and hardening are serious, and soil fertility tends to decline. Therefore, people of insight strongly advocate the use of organic fertilizers and “biological pesticides”. Photosynthetic bacteria have been proved to be not only a high-quality organic fertilizer, but also enhance the disease resistance of plants. Photosynthetic bacteria can be used as base fertilizer, seed dressing and foliar spraying.
Application of photosynthetic bacteria in planting
1. Increase crop yield: Photosynthetic bacteria can promote the transformation of soil materials, improve soil structure, improve soil fertility and promote crop growth. Most photosynthetic bacteria have nitrogen fixation ability and can improve the level of soil nitrogen. Through their metabolic activities, they can effectively improve some organic components, sulfide and ammonia nitrogen in soil, and promote the transformation of harmful pollutants (such as pesticides and chemical fertilizers). At the same time, it can promote the proliferation of beneficial microorganisms and participate in the material cycle of soil ecology. In addition, the abundant physiologically active substances produced by photosynthetic bacteria, such as proline, uracil, cytosine, vitamins, coenzyme Q and carotenoids, can be directly absorbed by plants, which helps to improve crop nutrition, activate the activity of plant cells, promote root development and improve the ability of photosynthesis and reproductive growth.
2. Improve the quality of agricultural products: Photosynthetic bacteria fermentation broth contains a variety of physiologically active substances. These physiologically active substances and Bacillus produce rich enzyme systems, which can either promote the growth of plant roots, or promote the growth of plant leaves, or promote the accumulation of some specific components in fruits, or increase the yield, so as to improve the quality of agricultural products.
3. Improve the antiviral activity of crops: Photosynthetic bacteria and bacillus can enhance the ability of crop disease resistance and prevention. Bacillus contains anti-bacterial and anti-virus substances, which can passivate the pathogenicity of pathogens and inhibit the growth of pathogens. At the same time, the activities of photosynthetic bacteria can promote the proliferation of beneficial microorganisms such as actinomycetes and inhibit the growth of harmful flora such as filamentous fungi, so as to effectively inhibit the occurrence and spread of some plant diseases.
4. Extend the storage period of fruits: Because photosynthetic bacteria have the function of disease resistance and disease prevention, they can prolong the storage period of fruits, and can also be used as preservatives for melons and fruits.
5. Improve soil microbiota and crop absorption of soil nutrients: Photosynthetic bacteria can increase the chlorophyll content of plants and promote the growth of nitrogen fixing bacteria, Rhizobium, actinomycetes and other bacteria in soil. After spraying photosynthetic bacteria on tobacco, radish, sweet potato, soybean and other crops, it can increase the number of nitrogen fixing bacteria, Rhizobium, actinomycetes and bacteria in soil, while filamentous fungi are reduced.
6. Reduce the toxicity of pesticides to crops and degrade residual pesticides.
