In the cold winter and spring seasons, the use of biological bacterial fertilizer can not only activate nutrient elements that are fixed in the soil, but also contribute to the growth of the root system, but it should not be used blindly. It should be determined according to the soil environment of different greenhouses, otherwise it is likely to Spending money did not achieve results. The following will introduce to you the application of biofertilizer in winter and spring. I. Soil moisture Excessive or insufficient soil moisture will affect the application effect of biological bacterial fertilizer. Because most of the biological bacteria in biological bacterial fertilizers are aerobic bacteria, they are active when the soil is dry and wet. Therefore, after the application of biological bacterial fertilizer must pay attention to reasonable watering, the best choice for sunny morning watering, so not only can increase the temperature, but also through the release of moisture. Pay attention to the best scratching after watering, in order to increase the soil permeability, which will help the bacteria to exert their effects. Second, the soil temperature The biological bacteria in biological bacterial fertilizers generally have the most active life activity in the soil at 18°C-25°C, and the life activities begin to decrease when the temperature is below 15°C, and the activity ability is already weak at or below 10°C, even in the dormant state. Therefore, in the winter and spring season, when greenhouse vegetables are applied to the bacterial fertilizer, it is necessary to pay attention to the regulation of the ground temperature. First, the temperature in the shed is controlled, and the temperature rises to warm the ground. General indoor temperature should be maintained at 25 °C -30 °C during the day is appropriate, the night temperature in the shed is low, in order to avoid ground temperature loss, to maintain a constant ground temperature, in addition to mulching, can be covered in the operation of crop stalks. Third, the soil pH Soil acidity or partial alkali is not conducive to the growth and reproduction of biological bacteria. Soil pH value of 6.5-7.5 is most suitable for the propagation of biological bacteria, vegetable farmers can be modified according to the soil conditions, so that the soil pH value of 6.5-7.5, to ensure the proliferation of biological bacteria. Fourth, increase organic fertilizer After the application of biological fertilizer, we must pay attention to increase organic fertilizer. Because biological bacteria can exert their effects on the premise of rich soil organic matter. Therefore, we must pay attention to the application of organic fertilizer before planting, generally 5000 kg per mu. Disclaimer: Some articles in this website have been transferred from the Internet.

Coenzyme Q10, also known as ubiquinone 10, is a fat-soluble quinone whose structure is similar to that of Vitamin K. It is named after the side chain on the six-position of the parent nucleus, the polyprenyl group, which has a degree of polymerization of 10. A quinone ring compound.
