甘薯根腐病是我国新发生的一种毁灭性病害。由于它属于一种土传病害,因此有人提出了轮作防病的措施。在所提出的参与轮作的作物中,棉花被列为其中的一种。鉴于甘薯根薯病菌的寄主范围,迄今研究报道甚少,棉花参与轮作能否取得积极的防病效果?此外,还考虑到甘薯[Ipomoea batatas(L.)Poir]为旋花科植物,与它同科的蕹菜(I.aquatica Forsk.)是否也有受到根腐病菌感染的可能?据此,我们于1980—1982年进行了以下试验。
Sweet potato root rot is a new devastating disease in our country. Because it belonged to a soil-borne disease, some people suggested measures for rotation prevention. Among the proposed crops involved in crop rotation, cotton is listed as one of them. In view of the host range of sweetpotato potato pathogens, few reports have been reported so far, and whether cotton is able to achieve a positive disease-prevention effect in rotation. In addition, it is also considered that sweet potato [Ipomoea batatas (L.) Poir] Is it possible for I. aquatica Forsk. To be infected with R. solani? The following tests were carried out in 1980-1982.
