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 agricultural productivity.
目的
研究黄连不同部位水浸提液的自毒作用。
方法
通过测定对种子萌发、幼苗生长及成株生长的影响，研究根分泌物、根茎提取物、植物残体分解产物及根际土壤水浸提液的自毒作用。
结果
黄连不同部位的水浸提液能够抑制黄连营养生长阶段。
结论
自毒作用是导致连作障碍的因素之一，本研究对黄连在农业生产中的管理与应用具有指导意义。
