在江苏沿海地区盐土农业示范基地(盐城点)盐碱地土壤上,于2012年对390份半野生棉材料进行耐盐性鉴定,结果表明:在土壤含盐浓度为中度(0.3%-0.5%)的情况下,试验总计1174个小区有549个小区出苗,三个重复间出苗一致性好的有50份材料,其中出苗一致性好且达到耐盐级别以上的有7份材料。
The paper takes 390 wild cotton materials to study the salt tolerance in Jiangsu coastal solonchak agriculture demonstration base (Yancheng) saline soil in 2012, the results show that: in the soil salt concentration is moderate (0.3% ~ 0.5% ) case, 549 of 1174 materials seedling, 50 materials have good seedling under three repeats, 7 materials have the con- sistent seedling and reach over salt tolerance level.
