| 摘 要： | 为探索土壤盐分离子组成对棉花出苗的影响,利用主成分分析方法与经典统计学,在棉花苗期对其出苗与否两种情况下的土壤盐分离子进行化验分析。结果表明,SO42-、Ca2+、K++Na+和总盐含量是影响棉花出苗与否的主要因素;总盐含量主要受SO42-、Ca2+的影响;土壤中SO42-、Ca2+、K++Na+离子含量保持较低标准有利于棉花出苗。 |

| Abstract: | In order to explore influence of the ionic composition of soil salinity on the emergence of cotton,this paper used principal component analysis and classical statistics method to test the soil salt ions under the cotton seedling emergence.The results showed that SO42-,Ca2+,K++Na+ and total salt were main factors affecting cotton seedling emergence;soil total salt was mainly affected by SO42-,Ca2+;SO42-,Ca2+,K++Na+ ion contention which keeps lower level and would benefit the cotton emergence. |
