松嫩平原盐碱地区发展水稻问题

【摘要】 盐碱地水稻开发对区域农业和农村发展具有重要意义。东北松嫩平原盐碱地区具有发展水稻的自然条件、但也存在许多障碍因素。土壤盐碱对水稻生长发育有明显的抑制作用。土壤次生盐渍化限制着水稻生产的持续发展。水稻不同品种耐盐性有差别。完善水田工程、改良土壤、建立适宜的耕作栽培体系可以有效地减轻盐碱对水稻的抑制作用．促进盐碱地区水稻开发的持续发展。更多还原

【Abstract】 Rice had great significance to regional agriculture and rural development in salinealkali area. Northeast China. There were some favourite natural conditions for rice here. but many obstacles existed. Soil salinity and alkalinity restrained rice growth obviously. and rice sustainable production was restricted by soil secondary salinization. Rice salt tolerance varied from one to another. The restriction of salinity and alkalinity to rice could be reduced by agricultural engineering, soil reclamation and proper cultivation. Rice sustainable development in salinealkali area would be promoted thereby.更多还原
