Biofertilizers rely on the role of microorganisms to increase production, and their effectiveness depends on good strains, high-quality microbial agents and effective application methods. Therefore, the principle of rational application of biological fertilizers is: First, to ensure that the bacteria have a sufficient number of effective microorganisms; second, to create environmental conditions suitable for the growth of beneficial microorganisms.
1. Bio-fertilizer must be of qualified quality, poor quality, and expired cannot be used. Fertilizer must be stored at low temperature (optimal temperature 4 ~ 10 °C), cool, ventilated, dark place, so as to avoid failure.
2. To minimize microbial death, direct sunlight should be avoided during application; Seed sowing, soiling after dressing, and can not be mixed with pesticides and fertilizers.
3. In general, the effect of direct application of bacterial fertilizers in acidic soils is poor. It is necessary to cooperate with the use of lime, ash, etc. in order to enhance the activity of microorganisms.
4. Microorganisms need enough water to grow, but too much water can cause poor ventilation and affect the activity of aerobic microorganisms. Therefore, we must pay attention to timely irrigation and drainage in order to maintain the right amount of moisture in the soil.
5. Microorganisms in biological fertilizers are mostly aerobic, such as rhizobia, autogenous nitrogen-fixing bacteria, and phosphorus bacteria. Therefore, the application of bacterial fertilizer must be combined with improved soil and reasonable farming to keep the soil loose and have good ventilation.
6. Microbiological activities require energy consumption. Organic matter is the main source of energy for microorganisms, and organic matter decomposition can also supply microbial nutrients. Therefore, the application of biological fertilizers must be combined with the application of organic fertilizers.
7. Microbial growth requires multiple nutrients. Therefore, sufficient NPK and trace elements must be supplied. For example, in the early stage of the growth of legumes, an appropriate amount of nitrogen must be supplied to promote crop growth and root nodule development, and to increase nitrogen fixation. Phosphate fertilizers can play a role in increasing nitrogen by phosphorus; moderate amounts of potassium and calcium nutrition are beneficial to the proliferation of microorganisms. Molybdenum is an indispensable element in the synthesis of nitrogenase by Rhizobium, and the combination of molybdenum fertilizer and rhizobia can significantly increase nitrogen fixation efficiency.
Flower shape design origin from the principle of aerodynamics, it reduces the surface area that impedes the flow of air from the air supply ceilings, resulting in a less turbulent flow underneath the light; the flower shape also can suit to mobile type, can choose straight arm or tube arm; the battery inside of the lamp base can last long for 8 hours, the flower lamp spot diameter is adjusted by electric, the brightness of different LEDs is adjusted automatically to change the spot size, which will avoid the possible occurance of mechanical malfunctions;
