BACILLUS CEREUS INTRODUCTION
Basic Overview:
Bacillus cereus has the strongest adaptability to ecological conditions. It is a dominant bacteria in the soil and has the ability to promote crop production, disease prevention, drought resistance, cold prevention and other aspects. Many Bacillus cereus are endophytes of some cereal crops, vegetables and trees. They are planted in living plants but do not cause any harm to host plants. They can promote plant growth, reduce diseases and pests, improve the ability of plants to resist adverse environments and reduce the use of chemical fertilizers, so as to establish a harmonious relationship with the host.
At present, the selected beneficial strains of Bacillus cereus are mostly used for the prevention and control of plant diseases, such as tea shift bacteria,
Cucumber Fusarium oxysporum, Rhizoctonia solani, Tobacco Fusarium oxysporum, Tea Moire Leaf Blight, Take All of Wheat, Wheat Grain, many kinds of pathogens, such as blight, Fusarium oxysporum, Fusarium oxysporum, and Pythium ultimate, have strong antagonistic effects.
Product Features:
1. Growth promotion: Bacillus cereus has the functions of increasing ears, grains, healthy plants, improving seedling quality,promote root growth, increase yield and prevent disease.
2. Competition: research shows that the way and mode of Bacillus cereus entering plants are basically the same as that of pathogenic bacteria similarly, after entering the host, Bacillus cereus has the characteristics of simple nutrition, large size and fast growth and reproduction, It can occupy the invasion site of pathogenic bacteria preferentially, compete with pathogenic bacteria for nutrition, and thus inhibit plant diseases.
3. Antagonism: The antagonistic substances produced by Bacillus cereus mainly include antibiotics, proteins, enzymes and volatility antibacterial substances, which can be transported in plants, have a direct inhibitory effect on pathogens. In 1945, Johnson, it was reported earlier that Bacillus cereus can secrete water-soluble antibacterial substances. Later, researchers found that Bacillus cereus ,the secretion of antibacterial substances is a very common phenomenon. These antagonists are harmless to humans, and most of them are non protein small molecules biotin, these antagonists can produce on the growth and metabolic activities of pathogenic bacteria and other microorganisms at very low concentrations toxic effect.
4. Induce plant resistance. Bacillus cereus can enhance crop damage to pathogens, drought, low temperature and freezing and delay the aging of crops.
Method of application of bacillus cereus 10 billion cfu/g WP:
1. As the raw material of biological fertilizer, it can be mixed with organic fertilizer, organic-inorganic compound fertilizer, organic matter, low content chemical fertilizer and other microbial strains, and its use amount can be implemented according to the standards of the factory.
2. Use method as biological bacterial fertilizer:
(1) Dip in the root: For transplanted crops, add proper amount of water to the product, dip in the root, and then transplant.
(2) Seedling watering: For seedlings that can be used in the future, the product can be mixed with 1000 times water and evenly watered with a pot.
(3) Leaf spray: dilute with water according to the amount of water required per mu, mix evenly, and spray after filtering. The time of leaf spray should be as early as possible. Spraying the seedling crops once before leaving the nursery; The transplanted crops shall be sprayed for the first time after planting and survival, and can be sprayed every 10-15 days when they are used for many times. For crops harvested and picked by stages, spray for the first time after the leaves are unfolded, and then spray for the next time. In principle, no spray will be carried out after flowering. To improve the cold resistance of overwintering crops, spray before winter. Fruit trees can be used for multiple spray from germination to harvest. The time of spray should be selected in the late afternoon as far as possible. If it rains after spraying, it needs to spray again. If it rains for more than 3 hours, it does not need to spray again.
(4) Fertilizer mixing: when used as seed fertilizer or base fertilizer, this product can be mixed with chemical fertilizer or organic fertilizer, and applied together with the fertilizer. It must be mixed and used at the same time, so as not to cause fertilizer melting and affect the quality of fertilizer sowing. Combination of seed mixing and fertilizer mixing: 1/4 seed mixing and 3/4 fertilizer mixing have better effect.
(5) Drip irrigation: add proper amount of nutrient solution to the strain for drip irrigation.
Application rate: 3000 g/ha for field crops, 6000 g/ha for cash crops and 10-20 g/plant for fruit trees.
Precautions:
1. It cannot be used together with antibiotics and fungicides.
2. Use it as soon as possible after unsealing. After use, tighten the bag mouth and pay attention to moisture-proof.
3. Store in a cool and dry place with a shelf life of 18 months.
