土壤盐分离子组成对棉花出苗影响的建模分析——以新疆巴音郭楞蒙古自治州为例

Modeling Analysis on Effects of Ion Composition of Soil Salinity on Cotton Emergence——Taking Mongolian Autonomous Prefecture of Bayingolin as An Example

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。

In order to explore influence of the ionic composition of soil salinity on the emergence of cot- ton, this paper used principal component analysis and classical statistics method to test the soil salt ions un- der the cotton seedling emergence. The results showed that SO24- ,Ca2＋ ,K＋ ＋Na＋ and total salt were main factors affecting cotton seedling emergence; soil total salt was mainly affected by SO24-, Ca2＋; SO24-, Ca2＋ ,K＋ ＋Na＋ ion contention which keeps lower level and would benefit the cotton emergence.
