| Abstract: In order to explore the cultivation method of original tomatoes suitable for autumn and winter in Miyun area, the original tomato 'Yuanwei No.1' was selected as the experimental material to compare the application effects of two grafting methods, which was inarching method and splicing method. Grafting survival rate and efficiency, growth period, stress resistance, commercial property and other indexes were analyzed and measured. The results showed that the original tomato grew vigorously after grafting, the plant height, stem diameter, leaf number and root growth increased significantly compared with the self-root seedlings, the yield increased by more than 10%, and good taste was maintained. By comprehensive comparison, the splicing method was more labor-saving and suitable for planting and spreading in Miyun area. |
