一“疏”一“堵”排水降盐，新疆超27万亩白花花盐碱地产出白茸茸棉

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]
