The newly-built ecological orange groves should adopt a combination of planting and breeding methods to form a material energy cycle chain with fruit as the center, grass as the foundation, livestock and poultry as carriers, biogas as the link, and water as the medium to achieve high-quality, high-efficiency and long-term utilization. The goal is to form a relatively complete ecological chain throughout the production to effectively increase the yield and quality of citrus fruits and increase the economic income of farmers. For example, if there are all empty plots of grass between the rows of the Orangery trees, then the pens, chicken houses, and digesters will be built. Mowing the grass to feed pigs and chickens, dropping the manure into the pond for fermentation, and using biogas residue and biogas slurry as organic fertilizer in the orange grove. Biogas digesters can effectively purify livestock manure and crop straws and litters and convert them into biogas, biogas slurry and biogas residue. Biogas residue is a full-price, fast-acting organic fertilizer, which generally contains 35% to 55% of organic matter, 20% to 30% of humic acid, and also contains about 40% of nitrogen, phosphorus, potassium and various trace elements. Improve fertility has a significant role. Biogas slurry is the product of anaerobic fermentation of organic matter. It contains 19 kinds of amino acids. It also contains antibiotics and other active substances. It has good effect on the prevention and control of orange plant diseases and insect pests. It can also be sprayed on the foliage of orange trees to increase tree vigor. Improve production and quality.
Can be used directly to maintain the integrity of cell morphology Guidelines recommend cell preservation fluids for sample preservation and transport. It can be used for sputum, bronchoscopic alveolar lavage fluid, pleural fluid and other liquid samples.
