"this vegetable doesn't have to wash, and it tastes good!" this morning, at the hainan green water and vegetables production base in the town of sanjiang, in the district of haeguchi, representatives of the seagum conference on modern agricultural cultivation and socialized production sites welcomed. It is known that hydroponic vegetables produced at this base are expected to produce 50,000-80,000 pounds of acre per year, more than five times the normal shed. This is a microcosm of modern agricultural intensification and socialization of production, which is being vigorously promoted at the sea mouth。
“our vegetables grow up in a plastic pipe with a fixed poaching hole at the height of the earth, and they grow up from `nutrient fluids' flowing through the pipe, avoiding contamination of the living environment by pesticides and fertilizers.” at the village hydroponics base, the head of the base, zhang xian jun, explained that it took about 15 to 20 days for a leaf to grow and harvest. Since the production cycle is shorter than that of the normal shed vegetables, and production is stable and can be produced uninterruptedly over the years, the annual acre production can reach 50,000 pounds, with a maximum yield of 80,000 pounds。
Participants found this new hydroponic vegetable growing in a sawn-pattern plastic shed. The platform of the hydroponic system at the top of the ground is about 1 metre above the ground, a row of plastic pipes have fixed implants, nutrients flow through the pipeline and feed vegetables with moisture and nutrients. According to zhang xijun, the base occupies approximately 200 acres, with a first phase of building a demonstration base of 50 acres。
An acre can grow 13,000 dens of vegetables, and more vegetables can be grown using a 3d v-type frame. It takes about 15 to 20 days for each leaf to grow to harvest, 50,000 pounds per acre per year for incubation and 80,000 pounds for empty cabbage. Vegetables grown in pipelines not only grow fast and produce high yields, but also accumulate less fibre in vegetables and have a rich nutritional value. High-level production of hydroponic systems has resulted in the elimination of soil infestation and contamination of soil with heavy metals and other pollutants。
In the view of the director-general of agriculture of haikou city, this new hydroponic technology is characterized by high yields, good quality, non-destructive soil structures, non-pesticides, no harmful product, and the recycling of nutrients, which is conducive to ensuring the safety of vegetable production. The city's agricultural department will work with the provincial agricultural sector and experts to develop a fully validated plan for the roll-out of this new hydroponic technology throughout the city。
At another location at the site, the west gang village of yongquan village, a field-sale plant hospital, where the farmer chen is constantly nodding his head while listening to the diagnosis of the “earth doctor” wang xiaoping. His bean horns grow bugs, and wang xiaoping, a farmer, is “treating” his bean horns。
Wang xiaoping, after testing with a professional tool, told him that it was not a pest, that it was a disease and that it was caused by constant cold temperatures. He then gave the old cure。
According to zhang zhang, the director of the yuichita agricultural science and technology service of the longhua district distribution agency, the city's marketing agency and longhua district jointly set up the longhua agricultural science and technology service centre to provide farmers with a child-sitter service. On the basis of a total area of 13,000 acres, 300,000 acres of irradiated in the river and river basin, benefiting 100,000 farmers。
It is understood that the service centres provide the nearby farmers with a full range of babysitting services, such as agricultural skills training, agricultural credit security, scientific production and marketing of cabbage, and have now trained more than 800 farmers。
