The ecological cultivation pattern of plastic greenhouses refers to a circular economy model in which greenhouses are taken as the center and plants, animals, and microorganisms are organically combined to form mutually dependent, complementary, and mutually reinforcing biological chains, thereby producing harmless foods. The ecological cultivation mode of plastic greenhouses consists of plastic greenhouses, pig houses, biogas digesters, straw feed fermentation tanks, melons, fruit and vegetable fields, etc. The greenhouse effect can be increased by more than 30%, and the resources can be reused for many times to reach the festival. Grain, fertilizer, energy conservation and pollution reduction purposes. Technology for each component
Plastic greenhouses. The area of ​​the plastic greenhouse is 8-9 meters wide from north to south and 40-60 meters from east to west.
Pig house. The pig house should be built on the entrance side of the plastic greenhouse, 3-4 meters east-west, 5 meters north-south, circle pit in the south, pig house in the north, and pigs with 6-10 pigs should be suitable; it is built around the wall and connected with the plastic film of the shed roof. Closed, separating the melons and fruits from the vegetable field, placing a pig and vegetable exchange carbon dioxide and oxygen in the middle partition wall and the vegetable, the size is 24cm 24cm.
Biogas digesters. The digester volume is 8-10 cubic meters and it is burned with four lights.
Straw feed fermentation tank. Straw feed fermentation tanks are built in the north of the pig house wall and are double-pooled with a capacity of 1.5 cubic meters. Each tank is fermented with dry straw powder of about 125 kilograms. The two pools are alternately fed at intervals of 1 week.
Fruit and vegetable field. The development area of ​​melons and fruits is more than 333 square meters and all kinds of fruits and vegetables are planted throughout the year. The 10 tons of biogas residue and biogas slurry produced each year can basically meet the needs of field base fertilizers and fertilizers.
Straw feed treatment. Straw feed first crushed (pig, poultry chopped some, cattle, sheep can be a little rough), with alkali treatment, adjust the pH value, add nutrients and fermentation of microbial agents, mix well, install the pool, seal the pool, anaerobic fermentation 2 weeks. The two pools are fed alternately, fermented and fed, used immediately, kept tightly to prevent mildew. Straw feed can also be mixed with cornmeal, cake flour, fish bone powder, auxin and so on. When the pigs are first fed, they should be adjusted to make them gradually adaptable. On the 1st, 0.5 kg of feed can be saved. At the same time, attention should be paid to adjusting the amount of drinking water of the pigs, and then drinking water after feeding.
The manure in the pen should be flushed into the biogas tank in time to avoid volatile ammonia and other poisonous vegetables. At the same time adjust the temperature and humidity of the piggery. The temperature should be more than 30°C. When the humidity is higher than 70%, open the skylight for ventilation. In order to supplement the carbon dioxide needed for the photosynthesis of melons and fruits, the partition wall and the ventilation window should be opened after sunrise in the morning and closed after sunset. The overheating or cloudy snow weather at midday should not be carried out.
The biogas digester can produce 1-2 cubic meters of biogas, which can be used for lighting and heating at night greenhouses, and can also be used to increase the carbon dioxide concentration in greenhouses. Biogas slurry can be fed to pigs, but also can be used as melon vegetable foliar fertilizer, watering fertilizer. Foliar sprayed with biogas dilute solution, 1 part of biogas slurry against 1-3 parts of fresh water, was sprayed on the back of the leaf in the afternoon, which is favorable for crop absorption and absorption. Biogas digesters can be taken after uncovering the shed in the hot season.
