吉林省盐碱地面积1453万亩，利用双向随机区组与盐碱土种植不同品种大区对比设计，采取定性与定量进行分析评价的试验方法。从农业育种角度对水稻的品种进行筛选，通过分析不同生长阶段不同品种水稻产量构成因素、水稻形态及生长发育进程和经济产量，进而筛选出更适宜盐碱地种植的水稻品种，为科学地开发和利用盐碱地资源提供支撑，不仅可以增加耕地面积，改善灌区农业生产条件，提高粮食产量和农民收入，对保障国家粮食安全、促进地区经济社会可持续发展和改善区域生态环境等具有重要作用。
吉林省鹽堿地麵積1453萬畝，利用雙嚮隨機區組與鹽堿土種植不同品種大區對比設計，採取定性與定量進行分析評價的試驗方法。從農業育種角度對水稻的品種進行篩選，通過分析不同生長階段不同品種水稻產量構成因素、水稻形態及生長髮育進程和經濟產量，進而篩選齣更適宜鹽堿地種植的水稻品種，為科學地開髮和利用鹽堿地資源提供支撐，不僅可以增加耕地麵積，改善灌區農業生產條件，提高糧食產量和農民收入，對保障國傢糧食安全、促進地區經濟社會可持續髮展和改善區域生態環境等具有重要作用。

Saline area of 1453 acres in Jilin Province ,the use of two-way randomized block with saline-alkali soil planting different varieties of large area contrast design ,test methods for qualitative and quantitative anal-ysis and evaluation performed.From the perspective of agricultural breeding rice varieties were screened by an-alyzing the constituent elements of different varieties at different growth stages of rice production ,rice shape and growth process and economic output,and thus more suitable for screening rice varieties grown in saline soil for scientific development and utilization Saline resources to provide support ,not only can increase the cultivated area,irrigated agriculture to improve production conditions,to increase food production and farmers' income,to ensure national food security,promoting sustainable development and improving the economic and social regional ecological environment plays an important role.
