摘要
采用盆栽法,对2个盐碱敏感性不同的水稻品种89-45(耐盐碱)和吉农大10号(不耐盐碱),在吉林省西部地区不同盐碱浓度的盐碱土中的表现进行了研究。盐碱胁迫导致叶面积系数变小,不耐盐碱品种较耐盐碱品种下降的趋势更明显;盐碱胁迫降低了水稻有效分蘖数,最终导致产量下降,胁迫越大,产量越低。
Two rice varieties with different tolerance to salinity and alkalinity were planted in four natural saline-alkali soils from different areas in the west of Jilin Province with pot experiment. Under saline-alkali stress, leaf area index was decreased, and the decreasing rate was larger in Jinongda 10 （susceptible variety） than that in 89-45（tolerant variety）. Salinealkali stress reduced effective tiller number and led to low grain yield of rice.
