With the growth of the development of biogas tanks in recent years, the application of biogas fertilizer is also increasingly important. At present, in the production of vegetables, due to a large number of chemical fertilizers, pesticides, and urban “three wastes†as production fertilizers for many years, various types of vegetables with poor quality of vegetables and harmful human health have entered various families, seriously affecting people’s health. With the adjustment of new agricultural industrialization, in order to adapt to the new situation, the “four in one†model can be adopted to vigorously develop pollution-free vegetable production. The “four-in-one†pollution-free vegetable production model is a combination of solar greenhouses, self-flowing biogas digesters, pig houses, and toilets. It implements energy, farming, planting, and three-dimensional production of virtuous cycle, comprehensive utilization of rural ecological agricultural production model The advantages are as follows: Biogas digester after anaerobic fermentation in biogas digesters can provide quick and efficient organic fertilizer for greenhouse cultivation all year round, which is conducive to the production and development of pollution-free products. The use of fermented biogas residue as a base fertilizer for vegetable production, and biogas slurry for various vegetable foliar top dressings not only enables all kinds of vegetables to grow vigorously, has a faster growing speed, and has increased disease resistance, and can prevent the occurrence of diseases and insect pests and improve vegetables. Yield and quality. After follow-up tests, fruits and vegetables grown with biogas fertilizer can increase production by 20%, leaf vegetables can increase production by about 30%, and can increase 3000-4000 yuan per mu. The use of biogas residue and biogas slurry as fertilizer for production in greenhouses not only sterilizes, eliminates poisons, eliminates disease, and exterminates insects. What's more important is that it can increase soil organic matter and increase soil fertility for years, providing enough for the production of pollution-free vegetables. stamina. Biogas slag and biogas slurry are used in the production of pollution-free vegetables as follows: Biogas residue is used for top dressing. The well-fermented biogas residue is an efficient and quick-improving organic fertilizer that can be used as a top-dressing fertilizer for various vegetables. The dressing is generally done with a planer hole and chasing the nest after chasing it. Fruits and vegetables such as tomatoes, cucumbers, eggplants, melons and the like, the average amount of topdressing fertilizer per acre is between 1,000 and 1,500 kilograms, and the average fruit and vegetable yield per acre can be increased by 15% to 20%. Biogas slurry is used for top dressing. When biogas slurry is used for vegetable topdressing, the mixed biogas slurry proposed from the discharge chamber is generally used with a ratio of 1:2 water slurry liquid to furrow irrigation. After the chase, the biogas fertilizer sinks into the soil and is then filled with water. Generally, the amount of topdressing fertilizer per acre is about 2000 kg. This method can generally increase the leaf menu output by more than 30%. Biogas slurry is used for vegetable top dressing. When the biogas slurry is applied to the foliage, the extracted biogas slurry must be filtered and the digested water must be 1:1. It can be sprayed directly on the leaves of various vegetables with an atomizer. The average spraying amount per mu is 150. - 200 kg, this approach will not only play a role in the sterilization of various types of vegetables, eliminate poison, eliminate disease, disinfestation, etc., and will make vegetables grow more vigorous, more vivid color. Spray water again about 20 hours after spraying and foliar fertilizer spraying once every 10 days. This practice can not only produce high-quality pollution-free vegetables, but also increase vegetable production by about 30%. With the continuous improvement of people’s living standards and the continuous improvement of people’s health awareness, traditional agricultural production methods and poor agricultural products will soon be eliminated by people. Green food and pollution-free vegetables will become more and more popular with people. The farmers’ friends used the “four in one†model early, cultivated in parallel, three-dimensional production, virtuous cycle, comprehensive utilization, savings and income generation, produced a variety of pollution-free products, improved the living standards of farmers, and made them move toward becoming wealthy as soon as possible. road.
