In accordance with local conditions, high-sulphur soil and rust paddy fields should not be used for biological bacterial fertilizers, because sulfur can kill biological bacteria. For flooded paddy fields, spraying is generally not used, and spraying methods are more effective. The optimum temperature for the application of the bacterial fertilizer due to temperature is 25°C-37°C, which is lower than 5°C or higher than 45°C, and the application effect is poor. It is not suitable for crop fields under high temperature, low temperature and drought conditions. Due to the mixing, it is advisable not to mix the fungus with fungicides, insecticides, herbicides, and sulfur-containing fertilizers (such as potassium sulfate, etc.) and straw ash, because these drugs and fertilizers are easy to kill the bacteria. Fertilizer can be applied 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 mixing with uncontaminated farmyard fertilizers. Due to quantity adjustments, fertilizers and organic fertilizers cannot be significantly reduced when biofertilizers are applied to fields where fertilizers have been applied for many years. 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. The time-adjustable biological bacterial fertilizer is not a fast-acting fertilizer, and it is best applied in the critical period of nutrition of the crop and the 7-10 days before the large amount of nutrient absorption period.
