Biological bacterial fertilizer is a kind of pollution-free new compound biological fertilizer developed from the natural world by the scientific formula and combined processing. To achieve its best performance, you should pay attention to five aspects.
First, pay attention to the application of soil. For soils with high sulfur content and rust fields, it is not advisable to apply biological fertilizers because sulfur can kill biological bacteria. For the paddy paddy field, it is generally not applied, and the spray method can be used, and the effect is more obvious.
Second, pay attention to the application temperature. The optimum temperature for applying the bacterial fertilizer is 25 ° C - 37 ° C, below 5 ° C, above 45 ° C, the application effect is poor. It is not suitable for the application of crop fields under high temperature, low temperature and drought conditions. At the same time, it should also be known that the optimum moisture content of the nitrogen-fixing bacteria is 60-70%.
Third, pay attention to mixed application, do not mix with fungicides, insecticides, herbicides and sulfur-containing fertilizers (such as potassium sulfate), straw ash and unfertilized farmyard fertilizer, because these pesticides and fertilizers are easy to kill. Biological bacteria. At the time of application, if the application of bacterial fertilizer is contradictory to prevention of pests and diseases, weeding can be carried out first, and then weeding and weeding after 48 hours.
Fourth, we must pay attention to the amount of application, and replace the chemical fertilizer with biological fertilizer to replace 30%, 40% and 60% in the first, second and third years respectively. Phosphorus and potassium fertilizers can only be supplemented and cannot be reduced. Because crops are dependent on fertilizers, they cannot be adapted at once.
Fifth, attention should be paid to the application time. The biological bacterial fertilizer is not a quick-acting fertilizer. Therefore, it is best to apply the crop in the critical period of nutrition and 7-7 days before the large absorption period.
