Excessive or insufficient soil water content will affect the application effect of biological bacterial fertilizer. Because most of the biological bacteria in the biological fertilizer are aerobic bacteria, it is only active when the soil is dry and wet. Therefore, after applying biological bacterial fertilizer, we must pay attention to reasonable watering, it is best to choose small watering in the morning on a sunny day, so that not only can increase the ground temperature, but also through the wind and humidity. Note that it is best to hoe after watering to increase the permeability of the soil and help the biological bacteria to exert their effects. After applying the bacterial fertilizer to the vegetables in the greenhouse in winter, we must pay attention to regulating the ground temperature. This requires that the temperature in the shed be controlled first, and the temperature rises rapidly. Generally, the temperature in the shed should be kept at 25 ℃ ~ 30 ℃ during the day, and the temperature in the shed at night should be kept between 15 ℃ and 18 ℃.
