Description
Technical Field
The invention relates to the technical field of planting greenhouses, in particular to a double-layer film coverage type southern grape cultivation greenhouse.
Background
The rain sheltering cultivation is gradually expanded from a planting area in the south, the rainfall is concentrated in the fruit bearing period of the grapes, the grape diseases are serious, the disease threat caused by high temperature and high humidity can be effectively solved by building the rain sheltering shed, and the using amount of pesticides is obviously reduced through the rain sheltering cultivation. The double-film covering means that besides the greenhouse film, a plastic film is laid in practice, the operation is simple, and the cost is low. The tectorial membrane has very obvious influence on the early surface temperature rise, and can make the surface temperature rise by 3-5 degrees. The main contradiction of greenhouse production, especially early production, is that the temperature is not matched mildly, the temperature rises quickly, the ground temperature does not come, the requirements for nutrients and water are greatly increased after the trees sprout, and if the low temperature causes the phenomenon that the growth of the tree root system cannot follow up, the tree root system can fail, so that the mulching film plays an active role in the early winter production.
However, current big-arch shelter of planting adopts the mode of the direct bottom rolling that makes progress of plastic film to ventilate when using usually, needs the manual work to roll the great plastic film of length in proper order like this, and the plastic film position department of rolling ponds easily, leads to sewage to spatter easily when releasing the plastic film once more, and the operation is inconvenient, and when the rolling ventilation in summer, external fly worm gets into the inboard of planting the big-arch shelter easily, and depend on the grape tree, cause the grape disease easily, reduce the speed that the grape grows.
