迈向“十五五”的发展图景｜白花花盐碱地产出白茸茸棉

Core Viewpoint - The article highlights the implementation of advanced irrigation techniques in Xinjiang's Kashgar region to improve the quality of saline-alkali land and enhance agricultural productivity [1][3]. Group 1: Agricultural Techniques - The new irrigation technology, developed by research institutions and universities, focuses on water-saving and salt suppression to improve crop yields on saline-alkali land [3][4]. - A demonstration area of 1,000 acres was established in Kizilsu Township to explore efficient methods for managing saline-alkali soil [3][4]. - The average salt content in the soil of the demonstration area was initially 28.8 grams per kilogram, with some areas exceeding 100 grams per kilogram [3]. Group 2: Crop Yield Improvement - The cotton yield in the region has significantly increased, with an average yield of 440 kilograms per acre in 2023, doubling from 2022 [3]. - The quality of the farmland has improved by two grades due to the implementation of the new irrigation techniques [3]. Group 3: Technical Innovations - The key innovation involves the use of underground drainage pipes to quickly remove salt from the soil, which is crucial for crop growth [4]. - The underground drainage system is designed to intercept rising saline water, preventing salt accumulation in the topsoil [4]. - Compared to traditional methods, the new technique reduces the remediation period for severely saline-alkali land from 5-6 years to just 2 years, while also cutting water usage by nearly half [4]. Group 4: Training and Adoption - Over 270,000 acres of severely saline-alkali land in Xinjiang have been equipped with the underground drainage system, and training has been provided to 8,800 farmers on the new techniques [5].
