茄子砧木引种试验

筛选和引进更多优质砧木资源是解决茄子连作障碍的关键技术,研究以早青茄(对照)为接穗,分别嫁接茄砧一号、托鲁巴姆、托托斯加3个茄子砧木品种,并分析了其嫁接效果。结果表明:3个嫁接处理成活率高;与对照相比,始收期延迟,早期产量极显著降低,但抗病性明显提高,总产量极显著高于对照,嫁接对接穗品质影响小,可作为优良砧木品种在岳阳地区交替应用与推广。

Introduction Test of Eggplant Rootstocks

The screening and introduction of more high-quality rootstock is the key technology to solve the con-tinuous cropping obstacle ,taking Zaoqingqie（CK）as the scion which was grafted on three varieties of eggplant rootstocks respectively including Qiezhen 1 ,Tuolubam and Tuotuosijia ,and the effect of grafting were ana-lyzed .The results showed that the survival rate of three grafting were high .Compared with the control ,the grafted plants exhibited delay of first harvesting time ,early yield was significantly reduced and showed signifi-cant higher of disease-resistance and output .Grafting had less impact on quality of scion .All of above ,Tuotu-osijia ,Qiezhen 1 and Tuolubam could be used interchangeably in local agricultural production as excellent root-stocks .
