"Four in one" ecological greenhouse farming mode

I. Overview of the model The "four-in-one" ecological greenhouse planting model and supporting technologies integrate natural regulation with artificial regulation. Through bio-conversion technology, biogas pools, pigs, greenhouses, and vegetables are organically combined on the farmer's land. A new type of ecological greenhouse planting model based on land resources, solar energy as a driving force, straw dung as raw material, biogas as a link, and planting and breeding was formed. In the same land, it achieved simultaneous production of gas and manure, planted and raised aquaculture, and established an energy ecosystem with more biological populations, a sound food chain structure, and energy flow and faster circulation, and it has become an agricultural and rural economic development. , An important technical measure to improve the ecological environment system and improve people's living standards.
Second, the composition of the model and technology assembly
1. The basic structure of this model. 200-600 square meters of greenhouses will be built, 20 square meters of livestock and poultry housing will be built in the greenhouse, and 6-10 cubic meters of biogas digesters will be built in the livestock and poultry housings. Animal manure will enter the digester for anaerobic fermentation. The installation of biogas lamps, biogas produced after fermentation, on the one hand for lighting, cooking; on the other hand, igniting the biogas lamp in the greenhouse, can play a role in increasing the temperature of the greenhouse, adding carbon dioxide gas fertilizer. The generated biogas slurry is used as an alternative to inorganic fertilizer topdressing and foliar spraying, and it can also play an effective role in pest control and disease treatment. Biogas residue is used as a base fertilizer and biogas slurry can also be used as a feed additive for pigs.
2. Main technique. Biogas digester construction and management technology: Biogas slurry as additive for pig technology; Biogas residue, biogas slurry for comprehensive use of alternative chemical fertilizers, pesticide technology; Prevention and control of gas hazard technology; Scientifically regulated pig house and vegetable planting areas to form benign cycling technology .

Silage Cover is a kind of agriculture film with black colour on one side and white colour on the other side, which has been widely used for hydroponics system,horticultural field,basement covering with feature of UV resistance,light and water proof,no-leaking and easy-use.

Advantage of silage cover , that is black and white film:

1: White side facing upwards to reflect sunlight back to plants and prevent insects attacking.

2:Black side is downward to block light,restrain growth of weed,mildew and algae.

3:It keeps the soil moist and warm

4:Reduce soil diseases

5:Protect plant from frog

6:Low Cost
