Tomato grafting method

Abstract

The invention relates to a tomato grafting method, which comprises the following steps of: sowing stock seeds; sowing cions and tomato seeds when the height of stock seedling is 4-6 cm; transversely cutting off top interior leaf at a position 4-5 cm above the lignification position of the root of the stock seedling, vertically cutting downwards from the middle position of the stock stem to a depth of 0.4-0.5 cm, transversely cutting at the depth of 0.5 cm to remove half of the stock stem with an incision angle of 90 degrees; removing root at a position 1.4-1.6 cm below the stem leaf of the cion seedling, vertically cutting upwards from the middle position of the cion stem to a depth of 0.5 cm, transversely cutting at the depth of 0.5 cm to remove half of the cion stem with an incision angle of 90 degrees; butting the incision of the stock and the incision of the cion and fixing with a fixture. Since the incisions of the stock and the cion are right angles, the contact area of the joint is large, the joint can be healed up completely, the incisions of the stock and the cion have strong affinity, and the survival rate reaches more than 93 percent. After grafting, a produced tomato variety has remarkably enhanced root-knot nematode disease resisting capability and TY virus resisting capability, and the yield of tomatoes is obviously improved.

Description

technical field [0001] The invention relates to a tomato grafting method, which belongs to the technical field of agriculture. Background technique [0002] Tomatoes are one of the main vegetables in my country. Due to successive years of planting, various diseases such as root-knot nematode and soil-borne diseases have become more and more serious, resulting in the decline of tomato resistance to drought, cold, low temperature, disease and insects. The fruit set rate of tomatoes is low and the yield is low. At present, tomato cultivation mostly adopts seedling cultivation, transplanting and planting seedlings. Grafted seedlings have not been widely promoted in production, and grafting technology is immature. Rootstocks suitable for tomato cultivation are relatively scarce, and grafting technology is lacking. Contents of the invention [0003] The problem to be solved by the present invention is to provide a tomato grafting method aimed at the deficiencies of the prior art...
