"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: Linyi Fertilizer Network Copyright
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. Linyi Fertilizer Network Copyright
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. Linyi Fertilizer Network Copyright
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. Linyi Fertilizer Network Copyright
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. Linyi Fertilizer Network Copyright
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.

Smart Lights
Our Smart Light has a longer lifespan and more complete functions. The life of the smart light is determined by the light decay, and there are four main reasons that affect the luminous decay. 1. The raw materials of the product. The less the impurities, the less the heat dissipation. All our products are made of original brass, and the quality of the products is strictly controlled from the raw materials. Second, the heat dissipation structure of the product. We have more than ten years of work experience in structure research and development personnel. Each product has undergone heat dissipation design, heat dissipation simulation, and heat dissipation experiment to ensure the best heat conduction and heat dissipation of the product. Third, the design of the power supply, the higher the efficiency of the power supply, the better the heat dissipation. Our electronic engineers with more than 15 years of work experience adopt imported chip solutions and use the smallest space to make the power supply with the highest efficiency and the lowest temperature rise. Fourth, for LEDs, we purchase light sources from American CREE or Japan's Citizen to minimize light decay.
Smart lights is available in wattage dimming, romotely controll, module replaceable. More importantly, we are professional in OEM and ODM. We are a brass landscape lights factory integrating R&D, design and manufacturing. Please click on the product to learn more about our products.
