Carefully observe and inspect the purchased products, and pay attention to the following items: whether the liquid fertilizer is precipitated or not, the degree of turbidity; whether the carrier particles of the solid fertilizer are uniform, whether it is agglomerated; whether the production unit is formal, whether it has a certificate of conformity, etc. It is better to know and consult with the relevant professionals.
Second, pay attention to the storage environment.
Generally, the biological fertilizer has strong low temperature resistance, but the high temperature resistance is weak. In addition to observing the environmental conditions of the merchant's storage place, the purchased fertilizer also has a short-term storage problem, such as no direct sunlight, avoiding moisture, drying and ventilation.
Third, pay attention to timely use.
The bio-fertilizer has a short effective period. Even a composite solid fertilizer should not be stored for a long time. Generally, it can be purchased within 2 months before use. If available, it can be used as purchased.
Fourth, pay attention to reasonable application.
According to the characteristics of biological fertilizers and in strict accordance with the requirements of the instructions, especially when it comes to spraying concentration, working equipment, application time and other issues, strict operating procedures must be carried out.
5. Pay attention to other medicines and fertilizers.
Biological fertilizers are generally acidic, and the population is weak and easy to be killed or killed before the microorganisms are multiplied. Especially when applying bactericidal drugs and chemical fertilizers, such as simultaneous application, the two lose the same, without clarifying other drugs and fertilizers. Prior to nature, it is preferred to apply the biofertilizer separately.
6. Pay attention to the continuity of application.
In addition to the base fertilizer, when spraying biological fertilizer, the effect is more obvious within a few days, and can last for more than ten to several tens of days. With the long-term exposure of microorganisms, especially the discomfort of high temperature conditions, the microbial population declines rapidly. Therefore, it should be replenished in time to ensure the continuity and effectiveness of its effects. For example, during the growing period of vegetables, spraying once every 20 days, the fruit trees can be sprayed 3 times to 5 times from the start of fruit setting to the time before harvest, and the general field crops can be sprayed 3 times or so, so that more obvious increase in yield can be obtained. Quality effect.
