Core Viewpoint - The introduction of a new water-saving and salt-reduction irrigation technology in Kashgar, Xinjiang, is significantly improving the productivity of saline-alkali land, with cotton yields doubling in one year due to effective management practices [1][2]. Group 1: Technology and Implementation - The new technology, developed by research institutions and universities, focuses on a coordinated approach to water-saving and salt-reduction irrigation, which has been implemented in a 1,000-acre demonstration area in Kizilsu Township [1]. - The key aspect of the technology is the underground drainage system that efficiently removes salt from the soil, allowing for better crop growth [2]. - The underground drainage pipes are installed 1 to 2 meters deep, spaced 20 to 40 meters apart, which helps to quickly remove salt dissolved in water during irrigation [2]. Group 2: Results and Impact - In 2023, cotton yields in the demonstration area reached 440 kilograms per acre, a significant increase from 220 kilograms per acre in 2022, indicating a doubling of productivity [1]. - The soil quality has improved by two grades, showcasing the effectiveness of the new irrigation technology [1]. - Over 270,000 acres of severely saline-alkali land in Xinjiang have adopted this underground drainage technology, benefiting approximately 8,800 farmers through training [3].

Core Viewpoint - The article discusses the innovative techniques being implemented in Xinjiang's Kashgar region to improve the quality of saline-alkali land and enhance agricultural productivity, particularly focusing on cotton cultivation. Group 1: Agricultural Techniques - The new technology developed by research institutions aims to improve saline-alkali land through a method called "water-saving salt suppression irrigation and drainage coordination" [2][3] - The technique involves underground drainage systems that help to quickly remove salt from the soil, significantly benefiting crop growth [3] - The introduction of this technology has led to a doubling of cotton yield per mu (approximately 0.067 hectares), from 220 kg in 2022 to 440 kg in 2023 [2][3] Group 2: Land and Crop Statistics - Approximately 42% of Xinjiang's 1.06 million acres of arable land is affected by salinization, with Kashgar County having over 80% of its farmland classified as saline-alkali [2] - The average salt content in the soil of the demonstration area was reduced from over 100 g/kg to an improved level, showcasing the effectiveness of the new techniques [2][3] - More than 270,000 acres of severely saline-alkali land in Xinjiang have been equipped with the underground drainage system, benefiting around 8,800 farmers through training [4]

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].
