Description

Technical Field

[0001] The invention relates to the technical field of agricultural greenhouses and carbon emission reduction, and in particular to a rainwater collection and nitrogen saving device on the roof of a vineyard multi-span greenhouse. Background Art

[0002] Grapes are a fruit that is deeply loved by consumers. In my country, the cultivation of fresh grapes is mostly carried out using greenhouses or rain shelters and other facility cultivation technologies to reduce diseases and insect pests, promote early cultivation and maturity, and put the grapes on the market earlier, so as to obtain higher grape quality and increase the content of soluble solids and aroma substances in the fruit.

[0003] There are two types of commonly used grape cultivation facilities. One is a simple rain shelter, which has a low cost and a short service life. It is mainly used in areas in the south where pests and diseases are serious. The other is a multi-span greenhouse for grapes, which is expensive but has a long service life. It can promote early or delayed cultivation of grapes, has better grape quality, high grape sales price, and good economic benefits for grape growers. It is generally suitable for large-scale cultivation of grapes.

[0004] However, the existing vineyard multi-span greenhouses are relatively simple in structure. There is a certain rainwater collection structure on the greenhouse, but due to the flat bottom design, it is easily blocked by solid materials such as bird droppings, resulting in poor rainwater collection and utilization. In addition, due to the lack of corresponding rainwater discharge and rainwater collection and storage, nitrogen content monitoring and rainwater utilization facilities, rainwater cannot be effectively utilized, thus affecting the overall use effect and efficiency of the multi-span greenhouse. In addition, rainwater contains a lot of nitrogen, and arbitrary discharge not only wastes water resources, but also pollutes the agricultural environment and increases carbon emissions. Summary of the invention
