Problems solved by technology

[0002] Tomato is the main vegetable crop under protected cultivation, and its cultivation area is expanding year by year. In order to increase production and prevent the occurrence of diseases and insect pests, tomato grafting technology is now widely used. Grafting cultivation can not only effectively control root diseases, but also has strong growth potential and high yield. Most tomato growers are proficient in grafting seedling raising technology, but the seedling rate after grafting is not high, the quality of the seedlings is not good, and it is easy to be infected with viral diseases, which increases the burden on farmers and seriously restricts large-scale tomato production.

Embodiment 1

[0018] A kind of tomato grafting method that can improve survival rate described in the present embodiment comprises the following steps:

[0019] (1) Choose wild tomato species with high resistance to bacterial wilt and root-knot nematode as rootstock, and use conventional varieties as scions. Before sowing, soak the seeds in warm water at 56°C for 4 hours, and then soak them in 40% trisodium sulfate 10 times solution for 15 minutes. , remove and clean germination;

[0020] (2) The rootstock was sown 8 days in advance, the rootstock was sown on-demand in sterile soil, the scion was sown on a flat border, and the scion was artificially planted in a nutrient bowl filled with nutrient solution for plant production 2 days before grafting;

[0021] (3) When the rootstock grows to 6 true leaves, it can be grafted. Use a blade to cut the rootstock stem 1.5cm below the cotyledons of the rootstock, remove the upper part, and cut it into a W shape on the stem plane. It is required that...

Embodiment 2

[0027] A kind of tomato grafting method that can improve survival rate described in the present embodiment comprises the following steps:

[0028] (1) Choose wild tomato species with high resistance to bacterial wilt and root-knot nematode as rootstock, and use conventional varieties as scions. Before sowing, soak the seeds in warm water at 50°C for 3 hours, and then soak them in 40% trisodium sulfate 10 times solution for 12 minutes. , remove and clean germination;

[0029] (2) The rootstocks were sown 9 days in advance, the rootstocks were sown on-demand in sterile soil, the scions were sown in flat furrows, and the scions were falsely planted in a nutrient bowl filled with nutrient solution for plant production 1 day before grafting;

[0030] (3) When the rootstock grows to 5 true leaves, it can be grafted. Use a blade to cut the stem of the rootstock 1cm below the cotyledon, remove the upper part, and cut it into a W shape on the stem plane. The cut surface should be smoot...

Abstract

The invention discloses a tomato grafting method capable of improving the survival rate. The tomato grafting method comprises the steps of variety selecting, strong stock culturing, scion forming, grafting and managing after grafting. High-quality seeds are selected and sterilized, a strong stock and scion are cultured, a W-shaped staggered grafting way is adopted, the contact area is enlarged, the rigorous and scientific later period maintenance is conducted, the resistance of a plant is improved, the cell division is promoted, the wound healing is accelerated, and the grafted young plant can recover and grow quickly. The survival rate of the grafted tomato young plant cultured according to the grafting method reaches more than 98%.
