The tomato is an annual or perennial herbaceous plant, the fruit is oblate or nearly spherical, orange or bright red, the fruit is rich in nutrition and has special flavor, and the tomato can be eaten raw, cooked, processed into tomato sauce or canned in whole fruit, and the like. Among them, cherry tomatoes are one of the varieties of tomatoes.
The root systems of greenhouse cherry tomato varieties mostly have the defects of weak disease resistance, poor water absorption and the like, so that the scions of the cherry tomatoes need to be grafted to rootstocks with developed root systems and strong disease resistance. The stem of one tomato is grafted to the stem of another tomato so that the two parts which are connected together grow into a complete plant, which is called the tomato seedling grafting technology.
The grafting method is a prerequisite for survival of tomato seedlings, and the wound healing process after grafting determines the grafting effect and the health condition of the seedling stage. At present, the grafting technology of tomatoes is very common, but the survival rate of grafted tomato seedlings is not high.

Firstly, the scion of the seedling is grafted on the stock, and then the stock is placed under proper humidity and temperature for wound healing, so that the wound can be better healed, and the survival rate of the seedling is improved. The healing of the grafting wound is to control the moisture content in the body, if the moisture of the root is too high, the high root pressure can lead the moisture to be accumulated at the grafting wound, and the healing of the wound is seriously influenced; if the water content of the leaves is too low, the leaves will wilting, and the due physiological function will be lost before the wound is healed, which will affect the health condition of the seedling. The regulator is sprayed to the wound, which is helpful for the wound to heal as soon as possible and can also improve the survival rate of the seedlings. Light intensity also is an important factor of tomato grafting wound healing, and light filling intensity increases gradually, can improve grafting wound's healing effect, if after the light intensity exceeded certain limit, can destroy the activity of grafting healing in-process relevant enzyme, leads to grafting wound tissue browning and necrosis to reduce the healing effect, and then also can influence the survival rate of tomato seedling.

Combining the example 1 and the comparative example 5, it can be seen that the survival rate of the seedlings in the example 1 is 89%, which is better than that in the comparative example 5, and the gradual increase of the light supplement time is more suitable, so that the healing of the grafting wound can be promoted, and the survival rate of the tomato seedlings can be improved.
Combining the example 1 and the comparative example 6, the survival rate of the seedlings in the example 1 is 89%, which is better than that in the comparative example 6, and shows that root irrigation of the seedling scions and the rootstocks is more suitable 48h before grafting, the condition of wound ponding caused by high root pressure is reduced, healing of grafting wounds is facilitated, and meanwhile the survival rate of the seedlings is improved.
Combining example 1 and comparative example 7, it can be seen that the survival rate of the seedlings in example 1 is 89%, which is better than that in comparative example 6, and shows that the irrigation of the seedling scions and the rootstocks before grafting is more suitable, the moisture of the tomato seedlings within 3 days after grafting can be provided, the healing of grafting wounds can be promoted, and the survival rate of the tomato seedlings can be improved.
As can be seen by combining the examples 1 to 8, the survival rate of the seedlings in the example 7 is 98%, which is better than that of the other examples, and the weight proportion of the quaternary ammonium salt compound and the indoleacetic acid in the example 7 is more appropriate, and the mixing amount of the other raw materials is also more appropriate, so that the healing of the grafting wounds can be promoted, and the survival rate of the seedlings can be improved.
The embodiments of the present invention are preferred embodiments of the present application, and the scope of the present application is not limited by the embodiments of the present application, so: equivalent changes in structure, shape and principle of the present application shall be covered by the protection scope of the present application.
