利用因子分析法分析影响欧洲菊苣产量的因素
|
摘要
在春播、秋播两个播期下,以穴播、条播、撒播3种方式种植欧洲菊苣(Cichorium intybus cv.Europe)测定其鲜草产量。结果表明:欧洲菊苣产量最佳组合A3B3C3,即采用撒播种植方式、密度在55株/m2、盖度为95%以上时产量最高。对影响产量较多的因素进行分析,无法确定影响产量的主要因素时,通过降维采用因子分析,利用公共因子进行分析。这样既减少了干扰因素,又抓住了影响产量的主要因素。
During two sowing periods of spring and autumn,planting Cichorium intybus CV.Europe in three ways of hole sowing,drill sowing and sowing,the fresh grass production was determined.The results showed that the best chicory production combination was A3B3C3,that is using the form of seeding planting,the yield was highest when density was in 55plants/㎡and coverage was more than 95%.For analysis of many factors influencing yield,when main factors cannot be determined,common factors analysis were used by dimensions' reduction.This reduces the interference factors and captures the main factors affecting its yield
