Recently, in the 10,000-mu facility agricultural base in Hotan County, Xinjiang's Hotan area, rows of tomatoes are growing gratifyingly.
Why can vegetables be grown in deserts?
The answer lies in the "soil" of the earth.
According to Song Zongke, technician of Xinjiang Shengshi Huaqiang Agricultural Technology Co., Ltd., the base adopts soilless cultivation technology, that is, instead of using traditional soil, slag, yellow sand, perlite, vermiculite, etc. are used as substrates. Seepage membrane to isolate the substrate from the original sandy soil.
Using his analogy, planting vegetables in this way is like planting flowers in flower pots, except that the flower pots are round, and in the greenhouse, they are changed into long strips.
The sand in the matrix can fix the roots of the plants, allowing the plants to take root quickly, while materials such as slag and perlite can retain water and fertilizer.
With the cooperation of these substrates, various fruits and vegetables can be grown in desert greenhouses, and high-quality and high-yield can be achieved through scientific management.
