With the growth of biogas digesters in recent years, the application of biogas is becoming more and more important. At present, in the production of vegetables, due to the large amount of fertilizers, pesticides and urban “three wastes†as production fertilizers over the years, the quality of vegetables is inferior, and various types of vegetables that are harmful to human health enter various families, seriously affecting people's health. With the adjustment of new agricultural industrialization, in order to adapt to the new situation, we can vigorously develop the production of pollution-free vegetables in a “four-in-one†model.
The “four-in-one†pollution-free vegetable production model is a rural eco-agricultural production model that combines solar greenhouses, self-flowing biogas digesters, pig houses and toilets to implement a benign cycle of energy, aquaculture, planting, and three-dimensional production. The advantages are as follows:
The biogas fertilizer after anaerobic fermentation in the biogas tank can provide quick-acting and high-efficiency organic fertilizer for greenhouse cultivation throughout the year, which is conducive to the production and development of pollution-free products.
Using fermented biogas residue as vegetable base fertilizer, using biogas slurry as various vegetable leaf top dressing can not only make various vegetable seedlings grow, grow faster, increase disease resistance, and prevent disease and insect pests, and improve vegetables. Yield and quality. After tracking and testing, the fruit and vegetables planted with biogas fertilizer can increase the yield by 20%, the leafy vegetables can increase the yield by about 30%, and the per mu can increase the income by 3000-4000 yuan.
Using biogas residue and biogas slurry as the production fertilizer in the greenhouse, it can not only sterilize, eliminate poison, eliminate disease, and eliminate pests. More importantly, it can increase the organic matter of the soil and increase the soil strength, providing sufficient production for pollution-free vegetables. stamina.
The biogas residue and biogas slurry have the following operation methods in the production and use of pollution-free vegetables:
Biogas residue is used for top dressing. The fermented biogas residue is a highly efficient and quick-acting decomposed organic fertilizer, which can be used as a top dressing for various vegetables at any time. The top dressing is generally chased by a pit, and after the chase is finished, the soil is sealed. Tomatoes, cucumbers, eggplants, melons and other fruits and vegetables, the average amount of topdressing per mu is 1000-1500 kg, and the average yield of fruits and vegetables can increase by 15%-20% per mu.
Biogas slurry is used for top dressing. When the biogas slurry is used for vegetable topdressing, the mixed biogas slurry proposed from the discharge material is generally mixed with the water and biogas slurry ratio 1:2, and after the pursuit, the biogas fertilizer is submerged into the soil, and then the water is poured again. Generally, the amount of topdressing per mu is about 2,000 kg, which generally increases the leaf menu yield by more than 30%.
Biogas slurry is used for vegetable leaf top dressing. When the biogas slurry is topdressed on the foliar surface, the extracted biogas slurry must be filtered through the slag. The water content of the biogas slurry is 1:1. It can be directly sprayed on the leaf surface of various vegetables with a sprayer. The average spraying amount per mu is 150. - 200 kilograms, this practice not only plays a role in sterilization, poisoning, disease elimination, pest control, but also makes vegetables grow stronger and brighter. Spraying water again about 20 hours after spraying, foliar application of fertilizer every 10 days, this method can not only produce high-quality pollution-free vegetables, but also increase vegetable yield by about 30%.
With the continuous improvement of people's living standards and the growing awareness of people's health, traditional agricultural production methods and inferior agricultural products will soon be eliminated by people. Green food and pollution-free vegetables will become more and more popular among people. Farmers' friends use the "four in one" model early, breed and raise, three-dimensional production, benign circulation, comprehensive utilization, and increase income, produce a variety of pollution-free products, improve the living standards of farmers, and make them become rich as soon as possible. road.
