近年来茄子的栽培面积不断增加，病、虫害的发生也不断增多，影响到茄子的产量和品质，而嫁接茄子从产量、品质、抗病虫害等方面均优于普通茄子。为了筛选茄子嫁接的优良砧木，以大龙长茄做接穗，选用托鲁巴姆、圆茄、线茄3个品种做砧木，从嫁接成活率、根颈粗、根系面积、茎粗、叶面积、抗虫性等方面进行了试验研究。结果表明，以托鲁巴姆为砧木，嫁接成活率最高，为100%，根颈较粗，根系面积较大，叶面积最大，叶数最多，株高最高，单株最重，最抗白粉虱，死苗率最低，建议在茄子栽培生产中推广应用。

In recent years, the production of eggplant in vegetables has been increasing, the occurrence of diseases and pests is also increasing. The grafted eggplant is better than ordinary eggplant in terms of yield, quality, disease resistance and pest resistance. In order to screen the excellent rootstock for eggplant grafting, three varieties such as Solanum torvum Sw., round eggplant and line eggplant were selected as rootstocks, and long eggplant was used as scion. The grafting survival rate, root neck size, root area, stem diameter, leaf area and insect resistance were measured. The results showed that the grafting survival rate of Solanum torvum Sw. was the highest (100%), the root neck size was thicker, the root area was larger, the leaf area was the largest, the number of leaves was the largest, the plant height was the highest, the weight was the highest, the resistance to whitefly was the strongest, and the death rate was the lowest. All things considered, Solanum torvum Sw. is the better rootstock for eggplant grafting.
