Farmland

"Bacterial fertilizer" is a new type of nitrogen-fixing bacteria collected from nature, which is scientifically formulated and combined to produce a new type of pollution-free Compound biological fertilizer. When applying bacterial fertilizer in farmland, the following points should be noted: It is not appropriate to apply biological fertilizer to soils with high sulfur content and rust fields because sulfur can kill biological bacteria. For the paddy field, generally do not spread bacteria Fertilizer, the effect of the spray method is more obvious. It is not advisable to apply bacterial fertilizer to farmland under high temperature, low temperature and drought conditions. The optimum temperature for applying bacterial fertilizer is 25-37 ° C. When the temperature is lower than 5 ° C or higher than 45 ° C, the application effect is better. difference. When the soil water content is between 60-70%, the fertilizer efficiency of the bacterial fertilizer is better. Mixing should not be mixed with fungicides, insecticides, herbicides and sulfur-containing fertilizers (such as potassium sulfate) and straw ash, because these drugs and fertilizers are very Easy to kill biological bacteria. If you must use the above drugs, fertilizer, you can first apply the fertilizer, after 48 hours, then fight drugs and weeding. When using the bacterial fertilizer for seed dressing, it is forbidden to mix the seeds mixed with the bacterial fertilizer with the seeds mixed with the fungicide. In addition, it should be prevented Mix the bacterial fertilizer with the unfertilized farmyard manure. Due to the quantity system, for the field where fertilizer is applied for many years, the application of biological fertilizer can not reduce the application of chemical fertilizer and organic fertilizer. Because crops are dependent on fertilizers, they are taken with biological bacteria. Nitrogen fertilizer, crops can not adapt at once. The amount of bacterial fertilizer should be replaced by 30%, 40% and 60% of the nitrogen fertilizer in the first, second and third years respectively. Phosphorus and potassium fertilizers can only make up and cannot be reduced. Time-dependent creature The bacterial fertilizer is not a quick-acting fertilizer, and it is applied best in the nutrient critical period of the crop and 7-10 days before the nutrient mass absorption period.
