Core Viewpoint - The agricultural practices in Qianhai Town are successfully transforming saline-alkali land into productive rice fields through innovative irrigation and pest control methods, leading to a promising harvest of drought-resistant rice varieties by December 10. Group 1: Agricultural Practices - Qianhai Town's rice farmers are currently engaged in a busy harvest, with a single vehicle capable of processing approximately 200 acres per day, allowing for the completion of 4,000 acres in about 10 to 15 days [2] - The local agricultural team has implemented a "water-saving + alkali drainage" intermittent irrigation method, adjusting water levels according to the rice growth stages [4] - Techniques such as "water control and sun exposure" for pest management are being utilized to minimize chemical pesticide use, while local sunlight is leveraged to enhance pest control [5] Group 2: Soil Improvement Techniques - The agricultural team is focusing on improving desert soil by using local sunlight and water to eliminate pests without chemicals, which is a critical aspect of their strategy [5] - Methods such as local drainage of alkali and salt, along with straw return to the soil, are being employed to create a sustainable cycle of "using water to nourish rice, using rice to improve soil, and using soil to conserve water" [5] - The decomposition of straw after harvest significantly contributes to soil improvement by increasing organic matter [5]
