摘要
目的:研究黄连不同部位水浸液对黄连生长的自毒作用。方法:采用生物测定方法,研究不同浓度的黄连根系分泌物、根茎浸提液、植株残体分解产物、根际土浸提液对黄连种子萌发、幼苗及成株生长的影响。结果:黄连不同部位水浸液对黄连生长有较强的抑制作用。结论:自毒作用是造成黄连连作障碍的重要原因之一,本研究对黄连的生产与管理具有重要意义。
Objective : To study the autointoxication of aquatic extracts from different parts of Coptis chinensis. Methods : By measuring the effects on seed germination, seedling growth and adult-plants' growth, the autointoxications of root exudates, rhizome extracts, plant residue decomposition products and aqueous extracts from rhizosphere soil were studied. Results: The aquatic extracts from different parts of C. chinensis could inhibit the nutritional growth stage of C. chinensis. Conclusions : Autointoxication is one of the factors leading to continuous cropping obstacle, and this study is instructive to the management and application of C. chinensis in agri- cultural productivity.
