In winter, when the temperature is low, the application of biological bacterial fertilizer can not only activate nutrients fixed in the soil, but also facilitate the growth of the root system, but it should not be applied blindly. It should be determined according to the soil environment of different greenhouses, otherwise it is likely to be spent. Money does not see results. One is the soil moisture After the application of biological bacterial fertilizer must pay attention to reasonable watering, the best choice for sunny morning watering, so not only can increase the temperature, but also through the release of humidity. Pay attention to the best scratching after watering, in order to increase soil permeability, conducive to the effectiveness of biological bacteria. The second is the soil temperature It is known that biological bacteria in biological bacterial fertilizers generally have the most active life activities in the soil at 18°C ​​to 25°C, and their life activities begin to decrease when they are below 15°C, and their activity ability is very weak or even dormant when they are less than 10°C. This requires first controlling the temperature in the shed to promote temperature rise with the temperature. In general, the temperature in the shed should be maintained at 25°C to 30°C during the day, and the temperature in the shed at night should be low. To prevent the ground temperature from dissipating, and to maintain the ground temperature constant, in addition to the mulching, the straw can be covered in the operation line. The third is the soil pH The data show that: when the soil pH is between 6.5 and 7.5, it is most suitable for the propagation of the biological bacteria. The vegetable farmer can carry out the transformation according to the conditions of his own soil, so that the pH value of the soil reaches 6.5-7.5, so as to ensure that the biological bacteria multiply. In addition, the role of biological bacterial fertilizer is achieved by the decomposition of organic matter in the soil by the organism. If the organic fertilizer in the soil is insufficient, it cannot be decomposed. Therefore, before planting vegetables, we must pay attention to the application of organic fertilizer, usually about 5000 kg per mu.
