Facility agriculture is a very modern agriculture, but now there are some problems in the actual development. Applying biogas ecological agriculture technology to facility agriculture can not only solve the problem effectively, but also improve agricultural output and optimize the quality of agricultural products. The continued development of facility agriculture.
1 Basic introduction of biogas ecological agriculture technology
The technology is based on the ecological principle, and the utilization of agricultural resources is improved by biogas construction, and the recycling of agricultural resources is promoted to improve agricultural production and work efficiency. This technology has a large space for development in the agricultural field.
The indoor area of ​​the production unit is 210~580m. The indoor sunshine is sufficient. The livestock house and the measurement are built inside. The building area is about 18m and 3m respectively. The building location is selected on the east or west side of the room. The biogas tank is built in the livestock house. At the bottom, the pool area is 9m. The solar energy is concentrated by the plastic film to realize the effective conversion of heat energy. At the same time, it can also play a good role in moisture retention and heat preservation. Even in winter, the indoor temperature can reach above 11 °C, which can effectively solve The problem of planting fruits and vegetables in the off-season ensures that the biogas digesters are effective against the cold. In addition, biogas lamps can also play a good role in indoor warming and gas fertilizer supply; biogas slurry can also play a role in promoting high quality fruits and vegetables, environmental improvement, efficiency improvement, cost reduction and resource conservation. The application of this model in facility agriculture is conducive to promoting sustainable progress in ecological agriculture.
2 Application of biogas ecological agriculture technology in facility agriculture
2.1 Principles of application
Applying a body of nitrogen dioxide fertilizer during the growth of the crop. There is 43% carbon on the vegetable soil cover, which is formed by photosynthesis. Among them, the suitable carbon dioxide concentration for crop growth is 0.15%, but only 0.02% in air. The concentration under photosynthesis is only 0.025%, which does not meet the development needs of plants in time. Therefore, sufficient supply of carbon dioxide concentration should be achieved through biogas combustion to promote the smooth growth of crops. Biogas fermentation. In this process, a large amount of biogas slurry and biogas residue are produced, and the inside thereof contains proteins, nitrogen, humic acid, vitamins, phosphorus, organic matter, amino acids, potassium and the like. The proper amount of biogas slurry sprayed by vegetables can be quickly absorbed by plants. At the same time, it can enhance photosynthesis, improve the absorption capacity of vegetables, promote chlorophyll synthesis, complete energy metabolism of vegetables, enrich the amount of dry matter, and improve the resistance to pests and diseases.
2.2 Application effect
It can promote the growth of plant growth in biogas slurry and biogas residue. It can be seen from the experimental analysis that the carbon dioxide concentration increases appropriately during the growth of the crop, and the leaf area, plant weight, photosynthetic efficiency and dry leaf ratio of the vegetable crops increase correspondingly. The specific gravity of the dried cucumber leaves increases by about 28%, and the leaves are obviously thickened; The amount of biogas residue, carbon dioxide and biogas slurry in fruit and vegetable crops. For example, in the experiment, cucumber not only increased the number of female flowers, but also increased the nutritional value of the experimental cucumber, and the result rate increased by about 21%; it was beneficial to increase crop yield. Increasing the amount of carbon dioxide in the growth process of vegetables can significantly increase the yield of vegetables, especially in early production. The output increases by about 35%, the output value increases by 45%, and the total output increases by 30%. After the tomato test, the average yield increased by 21%. After the green pepper test, the average yield increased by 29%; it is conducive to the optimization of crop product quality. Appropriate increase of biogas residue or carbon dioxide during the crop growth stage can improve crop sales and agricultural economic benefits on the basis of optimizing crop quality. The above-mentioned fruits and vegetables were also selected for experimental experiments. The market demand for participating fruits and vegetables was high, and it was highly recognized by consumers. The soluble sugar ratio of fruits and vegetables increased by 14% compared with that before the experiment, and the amount of Vc increased accordingly.
3 Benefit Analysis
Social benefits. Based on rural biogas to achieve innovation in agricultural production methods, at the same time, this is also an effective dissemination of civilized production methods, excellent production methods, and cleaner production methods, which can improve agricultural production efficiency to a certain extent, improve farmers' economic income; and ecological benefits. Biogas raw materials are mainly derived from human livestock manure. The fuel produced is clean and non-polluting, and can effectively replace liquefied gas. Biogas can also play a role in the supply of nutrient fertilizers in the production of fruits and vegetables. After the treatment of biogas slurry, it can provide edible materials for water production. Biogas ecological agriculture is embodied in three modes: ecological orchard, ecological greenhouse and ecological farm. Among them, ecological orchards are mainly composed of orchards, biogas digesters and livestock houses; ecological greenhouses are mainly composed of toilets, biogas digesters, livestock houses and solar greenhouses; ecological farms are based on large-scale aquaculture, mainly from farms and Type biogas engineering composition; economic benefits. Livestock houses and biogas digesters (9m) have a construction fund of about 4,500. Each biogas tank can provide 5t of biogas residue and 4.5t of biogas slurry per year. The application of biogas fertilizer can save 450 yuan of fertilizer per year; the economic benefit of greenhouse can be increased by 21% or more. The economic income of biogas greenhouses exceeds 280,000 yuan/hm. Biogas can directly bring economic benefits. At the same time, it will promote high-yield crop production and plant optimization, thereby improving agricultural economic benefits, expanding farmers' income, and promoting the sustainable development and ecological development of facility agriculture.
4 Conclusion
Biogas ecological agriculture technology is applied to facility agriculture, that is, on the basis of innovative facility agriculture model, improving agricultural production efficiency, optimizing agricultural product quality, and deepening agricultural reform. Targeted biogas eco-agricultural technological innovation, improve the application rate of the technology in facility agriculture, in order to achieve sustainable progress in facility agriculture and optimize the development of facility agriculture.
