| 摘 要： | 基质栽培是工厂化无土栽培的一个重要分支。结合牡丹品种胡红牡丹的生产实际,采用多元统计中主成分分析法、聚类分析法,对14种栽培基质配方进行了优劣等级的划分。首先确立胡红牡丹的农艺指标体系,然后用主成分分析法对指标体系进行筛选,接着用聚类分析得出基质配方的优劣等级,最后就各优劣等级进行了概述。

| Abstract: | In this paper,by sampling and analyzing the soil in roadarea of Ji'er railway, the impacts led by railway construction to soil characteristics such as granularity,moisture and organic compounds are analyzed and discussed. The erosiblity of the two kinds of upper soil in railway roadarea is studied, and it is taken for that wind erosion intensities of the soils and the upper wind speed admit a relationship of power function. |
