The newly constructed ecological orange orchard should implement a combination of planting and raising methods to form a fruit-centered, grass-based, livestock-based carrier, biogas-based link, and water-based material and energy circulation chain to achieve high-quality, efficient, and long-term use. The goal is to form a relatively complete ecological chain throughout the production to effectively increase the yield and quality of citrus and increase the economic income of fruit farmers. For example, all the open spaces between the trees in the orangery are planted with grass, and then pig pens, chicken coops and biogas digesters are built. Weeds are fed to pigs and chickens, and the manure is fermented in the pond. Biogas residues and biogas slurry are used as organic fertilizer in the orangery. The biogas digester can effectively ferment and purify livestock manure, crop stalks, and litter, and convert it into biogas, biogas slurry and biogas residue. Biogas residue is a full-value fast-acting organic fertilizer. It generally contains organic matter 35% -55%, humic acid 20% -30%, and also contains about 40% nitrogen, phosphorus, potassium and various trace elements. Improving fertility has a significant effect. Biogas slurry is the product of organic matter after anaerobic fermentation. It contains 19 kinds of amino acids, and also contains antibiotics and other active substances. It has a good effect on the prevention and treatment of orange tree diseases and insect pests. Improve yield and quality. Disclaimer: Some articles on this website are transferred from the Internet.
