宁夏引黄灌区,素称“塞上江南,鱼米之乡”,种稻历史悠久。解放后,水稻产量不断提高,特别是文化大革命以来,在毛主席革命路线的指引下,广大贫下中农,以批林整风为纲,深入开展农业学大寨的群众运动,全面贯彻农业“八字宪法”,实行科学种田,使水稻生产有了进一步的发展。全区平均单产较解放初期翻了一番,涌现出一批一季超千斤的大队和生产队,显示了我区水稻生产有巨大的潜力。引黄灌区水利资源丰富,地势平坦,土质肥沃,日照充足,昼夜温差大,病虫灾害较少,这些对水稻的生育是很有利的。但是,也应看到,本区无霜期较短,有效积温偏低;有的地方盐碱涝洼,加之肥料不足,耕作粗放,发展
Ningxia Yellow River Irrigation District, known as “plug Jiangnan, Yumizhixiang”, rice has a long history. Since the liberation, the output of rice has been continuously increasing. Especially since the Cultural Revolution, under the guidance of Chairman Mao’s revolutionary line, the majority of poor and middle-level peasants have adopted the principle of “rectifying forests and rectifying forests” as their key link, carrying out mass movements in agriculture and learning Dazhai’s constitution, ", The implementation of scientific farming, so that rice production has been further developed. The average yield of the entire district doubled that of the early days of the liberation, and a batch of brigades and production teams with a super-kilogram in one season emerged. This shows that rice production in our region has great potential. Yellow River Irrigation District is rich in water resources, flat terrain, fertile soil, adequate sunshine, large temperature difference between day and night, fewer pests and diseases, these are very beneficial to the growth of rice. However, we should also see that the frost-free period in this area is short and the effective accumulated temperature is low. In some places, saline-waterlogged depressions, coupled with inadequate fertilizers and intensive cultivation, develop
