"Bacterial fertilizer" is a kind of pollution-free new compound biological fertilizer which is processed from the natural bacteria and processed by artificial purification and rejuvenation. Good bacterial fertilizers, such as Jinbao bacterial fertilizer, not only contain a large number of nitrogen-fixing, phosphate-dissolving, potassium-dissolving bacteria, but also organic matter, humic acid and trace elements. Pay attention to the following points during the application process:
1. Validity period At present, the survival time of effective microbial fertilizers in China is less than one year. Therefore, the purchased microbial fertilizer should be used as soon as possible, and the storage time is too long, and the dormant state of the strain may be destroyed. There are also some microbial fertilizers that can be stored for a long time. For example, the Golden Baby Microbial Fertilizer can be stored for 2 years.
2. The optimum temperature for temperature application of bacterial fertilizer is 25 ° C ~ 37 ° C, below 5 ° C, above 45 ° C, the application effect is poor. It is not suitable for the application of crop fields under high temperature, low temperature and drought conditions. The nitrogen content of the nitrogen-fixing bacteria fertilizer is 60% to 70%.
3. Locations for high-sulphur soils and rust fields, it is not advisable to apply biological fertilizers because sulfur can kill biological bacteria. For paddy paddy fields, it is generally not necessary to apply, and the method of spraying will be better.
4. The number of bacteria that can not reach the standard can not be purchased. The state stipulates that the effective viable count of microbial agents is ≥200 million/g (particles 100 million/g), and the effective viable count of compound microbial fertilizers and bio-organic fertilizers is ≥20 million/g. If this standard is not met, the quality of the product will not meet the requirements. Such as the number of viable bacteria in the Golden Baby microbial fertilizer, about 400-600 million / gram.
5. Period bio-fertilizer is not a quick-acting fertilizer, and it is best applied in the nutrient critical period of crops and 7-10 days before the nutrient mass absorption period.
6. Mixing should be careful not to mix the bacterial fertilizer with fungicides, insecticides, herbicides and sulfur-containing fertilizers (such as potassium sulfate) and straw ash, because these drugs and fertilizers can easily kill the bacteria. Or first apply the fertilizer, after 48 hours, then fight the herbicide. If seed dressing, avoid mixing with seeds that have been mixed with fungicide. It should also prevent mixing with unfertilized farmyard manure.
7. Dosage For the field where fertilizer has been applied for many years, the application of biological fertilizer should not reduce the application amount of chemical fertilizer and organic fertilizer, because the crops are dependent on chemical fertilizers, and the replacement of nitrogen fertilizer with biological fertilizer can not be adapted at once. Therefore, the substitution amount should be 30%, 40% and 60% in the first, second and third years respectively. Phosphorus and potassium fertilizers can only be supplemented and cannot be reduced.
