网隔栽培法对生姜姜瘟病防治及产量的影响

The Effects of Gridding Cultivation Pattern on Bacterial Wilt Control and Yield of Ginger

姜瘟病是由青枯雷尔氏菌(Ralstoniasolanacearum)引起的一种细菌性病害,被称为生姜种植产业的“癌症”.本试验设计了一种“网隔栽培法”,并探索其对土传姜瘟病发病率和生姜产量的影响.结果表明,经过连续3年的田间验证,相比传统栽培法,“网隔栽培法”种植可显著降低姜瘟病的发病率,平均减少了6.08个百分点,平均防治效果达到了48.33%;同时,生姜产量平均增加了13.21%.这种“短行播种、纵横开沟、深沟隔病”的“网隔栽培法”为姜瘟病的绿色防控提供了新方案,也为其他蔬菜、中药材等植物的土传病害防治提供了新的借鉴思路.

Ginger blast is a soil-borne bacterial disease caused by Ralstonia solanacearum and known as the‘cancer’of ginger.In a study reported in this paper,a“gridding cultivation pattern”was designed and its effect on the incidence rate of bacterial wilt and yield of ginger was investigated.The results of a 3-year verification experiment indicated that compared with the traditional cultivation pattern,gridding cultivation pattern significantly reduced the incidence rate of soil-borne bacterial wilt by 48.33%,the control efficiency being as high as 6.08%,and increasedginger yield by 13.21%.In conclusion,this gridding cultivation pattern with the characteristics of“sowing in short rows,ditching vertically and horizontally,and isolation of pathogens”provides a new and green control strategy,not only for ginger blast,but also for other soil-borne diseases.
