冬暖大棚茄子以其亩产量14000kg,亩产值3～4万元的极大优势,使茄子冬季栽培面积迅速增加。由于连年种植,连作障害黄萎病日益严重,使冬暖大棚茄子大面积死亡,甚至绝产。1997年山东省科委下达《大棚茄子嫁接研究开发》课题,经过两年试验,筛选出了优良抗病砧木及亲和力高的接穗品种。1999年4月14日经专家测定,自根苗(CK)黄萎病发病率为80%,嫁接苗黄萎病发病率仅为10%,对黄萎病防治效果达90%,增产90.9%。材料与方法 Winter warm eggplant greenhouse with its yield 14000kg, the output value of 3 to 40,000 yuan a great advantage of the rapid growth of winter eggplant cultivation area. As consecutive years of planting, continuous crop damage Verticillium growing increasingly serious, so that large areas of winter greenhouse eggplant death, or even abortion. 1997 Shandong Provincial Science and Technology Commission issued a “greenhouses eggplant grafting research and development” project, after two years of testing, screened a good resistance stock and high affinity scion varieties. According to the experts’ determination on April 14, 1999, the incidence of Verticillium wilt (CK) was 80%. The incidence of Verticillium wilt was only 10%. The control effect on Verticillium wilt was 90% and the yield was 90.9%. Materials and Methods
