摘要
通过在分析不同植被恢复区里施用不同聚丙烯酰胺剂量下土壤含水量变化的基础上,应用方差分析及LSD多重比较法进行了研究,研究结果表明:各种不同剂量的聚丙烯酰胺处理在水平度为0.05上和0.01上分别呈显著水平和极显著水平。而且,不同植被恢复区随聚丙烯酰胺剂量的加大土壤含水量规律性变化较强。
This paper studied and compared that soil moisture content change under different polyacrylamide dosage in the different vegetation areas, and variance analysis and LSD multiple comparison tests also have conducted the research. The results showed that they are remarkable in 0.05 level and extremely remarkable in 0. 01 level when treat with different dosage polyacrylamide. In addition, the regularity change between soil moisture content and polyaerylamide dosage were remarkable.
