In the fruit planting, biogas fertilizer has the characteristics of cultivating trees, green leaves, and obvious reduction of pests and diseases. The fruit tastes pure, which is 30%-50% higher than the application of chemical fertilizers. Spraying biogas slurry on citrus leaves can increase yield, effectively improve the ability of fruit trees to resist cold and freeze, increase the fruit setting rate, prevent pests and diseases, and reduce the amount of pesticides and fertilizers. Shatian pomelo applied biogas fertilizer, the acidity decreased, and the edible rate and sugar content of pulp increased significantly. The application of biogas fertilizer to plant watermelon is compared with the application of chemical fertilizer. The application of biogas fertilizer of 3000 kg can increase the yield by 360 kg. The difference is extremely significant. At the same time, the sweetness of watermelon is improved. The continuous use of biogas fertilizer for 3 years can effectively control watermelon wilt.
Improved soil The long-term use of biogas fertilizer can loosen the soil, is conducive to soil microbial activities and the formation of soil aggregate structure, increase soil organic matter content, enrich soil nitrogen, phosphorus and potassium nutrients, and activate trace elements and microorganisms in soil. Practice has proved that biogas fertilizer is not only a good quality organic fertilizer, but also a good soil amendment.
Prevention and control of pests and diseases Biogas fermentation broth can be sprayed on the foliar surface or soaked to achieve the purpose of controlling pests and diseases. Combined with certain chemical pesticides, it can reduce the amount of pesticides and have better effects than chemical pesticides alone.
