技术改良盐碱地 新疆图木舒克沙漠水稻迎丰收

Core Insights - The desert rice cultivation in Tumushuke City, Xinjiang, is experiencing a successful harvest, with 4,000 acres of late-maturing rice expected to be harvested by December 10 [1][3]. Group 1: Agricultural Practices - The local agricultural team has successfully transformed saline-alkali land by planting drought-resistant and salt-tolerant rice varieties, utilizing a "water-saving + alkali drainage" irrigation method [3]. - The irrigation strategy is flexible, adjusting water volume according to the different growth stages of the rice [3]. - To improve soil quality, techniques such as "water control and sun exposure" for pest control are employed, along with local practices like salt washing and straw returning to the soil [3]. Group 2: Pest Management - The pest management strategy avoids chemical pesticides, instead using water infiltration and sunlight to eliminate pests, which is a crucial aspect of the cultivation process [5]. - The approach also focuses on preventing soil salinization by ensuring water is absorbed locally to wash away salts [5]. Group 3: Soil Improvement - After harvesting, the decomposition of rice straw significantly contributes to soil improvement by adding organic matter [5].
