华重楼根茎腐烂病发病情况调查与病因分析

Investigation on the Incidence of Rhizome Rot of Paris Polyphylla and Its Etiological Analysis

华重楼根茎腐烂病严重威胁重楼生产,为了解华重楼根茎腐烂病的发病情况,为病害防控提供实践依据。项目组分别于2018年和2019年对福建省南平市光泽县和三明市沙县的3个华重楼种植基地的发病情况进行了调查,结果发现采用限耕容器栽培的华重楼未发生根茎腐烂病,采用仿生态栽培的华重楼根茎腐烂病发病率显著低于采用起垄栽培的华重楼。起垄栽培和仿生态栽培的华重楼2019年度根茎腐烂病的发病情况比2018年严重。调查结果表明,在发病严重的地块,采用限耕容器栽植华重楼是一种较好的选择。

The rhizome rot of Paris polyphylla is a serious threat to the production of P.polyphylla.In order to understand the incidence of rhizome rot of P.polyphylla and provide practical basis for the disease prevention and control,our project team investigated the incidence of rhizome rot in the three planting bases of P.polyphylla in Guangze County of Nanping City and Shaxian County of Sanming City in Fujian Province in 2018 and 2019,respectively.The results showed that no rhizome rot occurred in P.polyphylla cultivated with the limited tillage container,and the incidence of rhizome rot of P.polyphylla with bionic cultivation was significantly lower than that of P.polyphylla cultivated with ridging.The incidence of rhizome rot of P.polyphylla cultivated with ridging and bionic cultivation in 2019 was more serious than that in 2018.The results showed that it was a better choice to plant P.polyphylla with limited tillage containers in the seriously infected plots.
