China's eighth largest desert test species 5200 mu of dry rice

Xinhua News Agency, Hohhot, June 9 (Reporter Li Yunping) At present, as China's eighth largest desert in Inner Mongolia Ulanbu and desert is trying to plant 5,200 acres of dry rice, in the sand and sand at the same time can harvest high-quality rice, will achieve ecological, economic and social benefits "three wins."
total area of 15 million mu of Ulaanbu and desert, of which nearly 4.3 million mu are distributed in Bayangar City, Lukou County. There is plenty of sunshine, day and night temperature difference, no pollution, for the cultivation of dry rice to provide favorable conditions.
days, more than 10 large-scale seeding machines continued to work in the sand of Shajin set Haisumuba Yin Baoligacha in Lukou County, completing the process of burying drip irrigation pipes, sowing seeds, covering up soil and so on.
According to Wei Zhiheng, head of the dry rice planting project, they will try to plant 5,200 mu of dry rice, using precision farming technology to sow seeds, using water fertilizer drip irrigation method, in accordance with organic rice standards for management. "We started on May 26th with more than 10 seeders a day to sow seeds, and we expect to complete the sowing by mid-June to mechanize and intensive operations." Wei Zhiheng said.
arid rice, also known as land rice, is an ecological crop formed by the long-term domestication and evolution of rice in the drylands without water layers, both in drylands and in water fields or depressions.
Wei Zhiheng said that the varieties tested are dry incense one, dry incense two, is expected to use 280 cubic meters of water per acre of irrigation water, than ordinary rice irrigation water consumption reduced by 600 to 800 cubic meters, greatly saving water resources. At the same time, the length of the dry rice root system is about 50 cm, which has a good anti-sand solidification effect.
Wei Zhiheng told reporters that the preliminary estimate, the cost of growing arid rice per acre is more than 2000 yuan, including land, water, fertilizer, drip irrigation pipe, labor, machinery and other costs;
according to the plan, Ulaanbu and the desert will focus on the development of multi-use heat, less water-intensive eco-agriculture, resource-protected industries, to achieve ecological, economic and social benefits of the overall promotion.
