Method for cultivating high-yield potato tomatoes through vegetative propagation

The invention discloses a method for cultivating high-yield potato tomatoes through vegetative propagation, and relates to a breeding technique in the field of crops. Potatoes are adopted as stock, tomatoes are adopted as scions, distant related vegetative propagation is carried out, and therefore the high-yield character of the potatoes is transferred to the tomatoes. The problem of plant grafting between different genera is solved, and the result shows that potato tomato grafted seedlings grow vigorously, the height of mature plants is 2 m or above, tomato fruits do not crack, the yield is obviously increased, and potato tubers on root systems are mature at the same time. According to the cultivated potato tomato plants, the tomatoes are borne on the upper portions, potatoes grow on roots, two kinds of fruits are borne overground and underground on the same plants, and the method has the advantages of saving land and fertilizer, improving quality and increasing the yield and being very obvious in economic b
