连作对菊花生长及其根际土壤养分的影响OACSTPCD
Response of Chrysanthemum Growth and Rhizosphere Soil Nutrients to Long-Term Continuous Cropping
为探明连作对菊花生长及其根际土壤养分的影响.以无连作(CK)、连作 2 年(CM2)、9 年(CM9)的菊花及其根际土壤为研究对象,测定菊花的农艺性状及其根际土壤养分含量,分析不同连作年限下菊花生长指标及根际土壤养分含量的变化特点.连作导致土壤养分失调、菊花生长不良、品质降低.长期(9 年)连作,使土壤有机碳、全钾含量较对照分别降低了 39%、5%,全氮、全磷含量分别增加了 60%、71%;菊花根系长度、根粗、表面积分别较对照降低 31%、22%…查看全部>>
In order to explore the effects of continuous cropping on the growth of chrysanthemums and the nu-trient status of rhizosphere soil.The study took chrysanthemums and their rhizosphere soil under no continuous cropping(CK),2 years of continuous cropping(CM2),and 9 years of continuous cropping(CM9)as re-search objects.Agronomic traits of chrysanthemums and the nutrient content of soil were determined,and the changes in growth indicators of chrysanthemums and n…查看全部>>
