摘要
吉林省盐碱地面积1 453万亩,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。
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 analysis and evaluation performed.From the perspective of agricultural breeding rice varieties were screened by analyzing 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.
