"Bacterial fertilizer" is a pollution-free new-type composite biological fertilizer that is obtained through the artificial purification and rejuvenation of active bacteria collected from nature. Good fungus fertilizers, such as goldfish bacteria fertilizer, not only contain a large number of nitrogen-fixing, phosphate-solubilizing and potassium-releasing active bacteria, but also organic matter, humic acid and trace elements. In the application process should pay attention to the following points:
1, valid period. Do not use microbial fertilizers that have been stored for more than the expiration date. At present, there are not many microorganism microbial fertilizers that have survived for more than one year. Therefore, the microbial fertilizers to be used should be used as soon as possible, and the effect of expired microbial fertilizers is definitely not good. There are also some microbial fertilizers that can be stored for a relatively long period of time. For example, when you use the golden manure microbial fertilizer, it is generally safe to store 2 years of the microbial fertilizer, and if it exceeds 4 years, the dormant state of the bacteria may be destroyed.
2, temperature. The optimum temperature for applying the fungus fertilizer is 25-37 degrees Celsius, less than 5 degrees Celsius, and higher than 45 degrees Celsius, and the application effect is poor. It is not suitable for crop fields under high temperature, low temperature and drought conditions. At the same time, it is also necessary to know that the moisture content of the soil with the optimum temperature of nitrogen-fixing bacteria is 60%-70%.
3, location. For high-sulfur soils and rusted paddy fields, it is not appropriate to apply biological bacterial fertilizers because sulfur can kill biological bacteria. For flooded paddy fields, it is generally not applied. Spraying will be better.
4, the number of bacteria. Microbiological fertilizers that do not meet the standard number of viable organisms cannot be purchased. The national regulations require that the number of viable microbial cells in the microbial agent be ≥200 million/g (100 million granules per gram), and the effective microbial count of composite microbial fertilizers and bio-organic fertilizers should be ≥20 million. /g. If this standard is not met, it means that the product quality does not meet the requirements. The number of viable bacteria in the golden baby microbial fertilizer is about 4 to 600 million/g.
5, period. Biological bacterial fertilizer is not a fast-acting fertilizer, and it is best applied at the critical period of nutrient nutrition and the period of 7-10 days before the large amount of nutrient absorption.
6, mixed. It should be noted that bacterial fertilizer should not be used in combination with fungicides, insecticides, herbicides, and sulfur-containing fertilizers (such as potassium sulfate, etc.) and straw ash, because these medicines and fertilizers can easily kill biological bacteria. Or apply the Fungicide first, after 48 hours, then weeding and weeding. If seed dressing, do not mix with seeds that have been mixed with fungicide. It should also prevent the mixing of manure with uncooked farmyard fertilizers.
7, the amount. For fields that have been applied with chemical fertilizers for many years, the amount of chemical fertilizers and organic fertilizers cannot be greatly reduced when biological fertilizers are applied. Because crops have a dependence on chemical fertilizers, the replacement of nitrogen fertilizers with biological bacterial fertilizers cannot be applied at once. Therefore, the amount of substitution should be replaced by 30%, 40%, and 60% in the first, second, and third years, respectively. Phosphorus and potash can only make up for it and cannot be reduced.
