[Central Media watch Gansu] Gansu Yuzhong: Highland Summer Cai Listing Ji Technology helps grow up

Gansu Yuzhong has a unique plateau climate and high selenium -rich loess. Although it is located in the northwest of water shortage areas, through the development of water -saving technology, the plateau summer vegetables become local characteristic industries.

Right now is the season when the plateau is listed. In a smart vegetable greenhouse in Yuzhong, about 100,000 lettuce is strong.

Advanced hydroponic planting technology Drought water to make full water articles

The northwest is dehydrated, and the elm is no exception. The annual precipitation here is about 400 mm, but the annual evaporation is as high as 1400 mm. A large -scale vegetable planting is relying on advanced hydroponic planting techniques in a lack of water.

Every half an hour, nutritional water infiltrates the plant root system through the pipeline and recycles. A stubble of vegetables consume only 15 cubic meters per mu, compared with the original greenhouse planting, it can save about 85%of water.

The top of the intelligent greenhouse is both a "parasol" and a "quilt", and the fans around them are transported into fresh air.

There are more than 20,000 such greenhouses in Yuzhong, which has extended the listing time of the plateau Xiacai from the original 3 months to 8 months. It can be said that science and technology have made the original plateau summer cuisine a "plateau summer autumn cuisine".

New Vegetables Promotion of Elm Tests in the province planting in the province

In the elm, there are more than 140 tomatoes, 122 species of peppers, and more than a thousand new vegetables are introduced into the test screening. The preferably suitable variety will be promoted to more than 9 million acres of vegetable planting areas in Gansu.
