摘要
为探明转基因抗虫棉的耐盐性,筛选出适合盐碱地种植的抗虫棉高产品种,不同盐分含量砂培试验与滨海盐碱地大田试验相结合,研究了不同基因型抗虫棉的耐盐性及其生育特点和产量表现。结果表明,供试抗虫棉品种间的耐盐性存在差异,但耐盐程度皆十分有限。从不同基因型抗虫棉的耐盐性、出苗成苗率、生长情况和产量等分析,以鲁棉研17、鲁棉研21、鲁536、中棉所45和鲁棉研18综合性状较好,适宜于盐碱地种植,可作为当前盐碱地植棉的适宜品种。
In order to explore the salt tolerance of Bt cotton and select high-yielding variety of Bt cotton that planted appropriately in saline soil, the salt tolerance, growth characteristics and yield of Bt cotton with different genotypes were studied through the experiment of sand cultivation with different NaCl content and field cultivation in coastal saline soil. The results showed that the salt tolerance of Bt cotton cultivar was not high though there are differences of salt tolerance among Bt cotton cultivars in this experiment. SCRC 17, SCRC 21, LU536, CRI 45 and SCRC 18 are better than that of the other cultivars by thinking of salt tolerance, forming seeding, growth and yield. These are appropriate cultivars grown very well in coastal saline soil.
