摘要:

为探讨土壤消毒对北京山区茶菊连作障碍防治效果,母株栽培前设常规对照(CK)和氯化苦熏蒸土壤消毒(Pic)2个处理,比较2种处理对温室土传病害和茶菊生长的影响。结果表明:与CK相比,土壤消毒处理母株移栽前和采穗期疫霉菌属和线虫的抑制率均达85%以上,插穗采收量显著提高31.47%,茶菊产量、总黄酮含量和绿原酸含量分别提高20.43%、10.14%和18.02%。土壤消毒可显著降低温室土传病害发生,提高插穗采收量,促进茶菊生长,提高茶菊产量,改善茶菊品质,可为北京山区茶菊产业发展提供参考。

Abstract:

We conducted a field experiment to evaluate the effects of soil disinfection on greenhouse soil-borne diseases and the growth of tea chrysanthemum under continuous cropping cultivation system. Taking Beijing tea chrysanthemum as experimental plant, treatments under conventional control (CK) and chlorinated bitter fumigation (Pic) were designed before mother plant cultivation. The results showed that compared with CK, the inhibition rates of Phytophthora spp. and nematodes were more than 85%, the cutting harvest was significantly increased by 31.47%, and the yield, total flavonoid and chlorogenic acid content of tea chrysanthemum were significantly increased by 20.43%, 10.14% and 18.02%, respectively. We concluded that soil disinfection could significantly reduce the occurrence of greenhouse soil-borne diseases, improve the harvest amount of cuttings, promote the growth, increase the yield, and improve the quality of tea chrysanthemum under the experimental conditions. Our results can provide reference for the development of tea chrysanthemum industry in the mountainous area of Beijing.
