由中国农科院农业资源与农业区划研究所主持研发的西北沿黄灌区盐碱地改良关键技术近日研发成功。该技术在西北沿黄灌区累计推广76.9万hm2,使中度盐碱地作物增产9.8%~14.6%,重度盐碱地作物增产26.3%~35.3%。西北沿黄灌区是我国西北地区重要的粮油主产区和生态脆弱带,传统大水漫灌方式造成农田在灌溉时段“盐随水走”和在非灌溉时段“水走盐留”现象循环发
The key technologies for improving saline-alkali land in the Yellow River Irrigation Area along the Yellow River, which is under the auspices of the Institute of Agricultural Resources and Regional Planning, Chinese Academy of Agricultural Sciences, have been successfully developed recently. This technology promoted a total of 769,000 hm2 in the Yellow River Irrigation District in northwestern China, boosting moderate saline-alkali crop by 9.8% -14.6% and heavy saline-alkali crop by 26.3% -35.3%. The Yellow River Irrigation District in Northwest China is an important grain-oil-producing area and ecological fragile zone in the northwestern region of China. The traditional method of flood irrigation resulted in farmland irrigation during “irrigation period” and irrigation during “non-irrigation period” Phenomenon cycle hair
