随着蔬菜生产集约化和规模化的快速发展,生产基地因连作引起的连作障碍和土传性病害越来越严重。茄子青枯病、枯萎病、黄萎病、根结线虫等病虫害因连作常常造成大幅减产甚至绝收,给菜农带了巨大的经济损失。在茄子生产上,嫁接栽培是克服土壤连作障碍和防控土传性病虫害最有效的栽培措施之一,近年在生产中得到快速、大面积的推广应用,防病增产效果显著。由于茄子亩定植株数较多,对嫁接苗需求量
With the intensive production of vegetables and the rapid development of scale, continuous cropping obstacles and soil-borne diseases caused by continuous cropping are becoming more and more serious. Eggplant bacterial wilt disease, blight, Verticillium wilt, root knot nematodes and other pests and diseases often result in continuous crop production or even cut-off, to vegetable farmers with a huge economic losses. In eggplant production, grafting cultivation is one of the most effective cultivation measures to overcome continuous cropping obstacles and control soil-borne diseases and pests. In recent years, it has been popularized and applied in production in a large scale in a large scale, and the effect of disease prevention and yield increase is remarkable. As eggplant acres planted more plants, the amount of grafted seedlings
