番茄嫁接防治温室根结线虫病的研究

Study on the grafted tomatoes controlling root-nematode in greenhouse

摘要: 试验研究番茄利用抗性砧木SIS-1嫁接防治温室根结线虫病结果表明，甲基溴（MB）、威百亩（MS）、甲基溴+不透膜（MB+VIF）、威百亩+不透膜（MS+VIF）、太阳能+生仿制剂（SS+BCA）5个处理小区嫁接番茄病情指数均为0；对照区嫁接番茄病情指数也由普通番茄的95.0降为8.4，增产率为102.01%；而甲基溴、威百亩、甲基溴+不透膜、威百亩+不透膜4个处理小区普通番茄产量间无显著差异，比对照区提高40%左右。

Abstract: The grafted tomatoes with resistant rootstock SIS-1 can resist the root-nematode（Meloidogyne spp.）.Disease indices of grafted tomatoes in the 5 plots（methyl bromide，metham-sodium，methyl bromide+VIF，metham-sodium+VIF and solar energy+BCA）are zero.The disease index of grafted tomatoes（8.4）is far lower than that of ungrafted tomatoes（95.0）and its yield has increased by 102.01% in the CK plot.There is no significant difference in disease indices among the four chemical fumigation approaches.The yield of ungrafted tomatoes in chemical fumigation plots is higher than that of CK plot and has increased by 40%.
