Tomato sleeve grafting technology introduction, tomato artificial grafting method and mechanical grafting method difference method

Tomato is a kind of vegetable that we all like to eat. We also have many ways to grow tomato. Do you know the grafting technology of tomato? do you want to know about it?

Sleeve grafting technique

The grafting method of tomato is commonly used for oblique cutting, and external objects are needed to subsidize and fix it, such as various grafting clips, rubber sleeves, bone needles and plastic needles, etc., in order to increase the close combination of rootstocks, among which rubber casing (bicycle inner tube wind hose, sub-vegetable center development method) is widely used by ordinary farmers because of its cheap consumable materials, convenient operation, good moisture retention and high survival rate.

At present, the sleeve grafting technology widely used in China mainly uses eggplant as rootstock and tomato as spike wood, which can be divided into artificial grafting and mechanical grafting.

Artificial grafting method

First, eggplant and tomato seedlings with a stem of about 1.8~2.8mm were selected with an ultra-thin blade above the cotyledons between the cotyledons and the first leaf, and cut off at an angle of 30 degrees; the left hand gently grasped the lower half of the rootstock; the right hand took a rubber hose with an inner diameter of about 2mm and a length of about 8mm; cut into the stem to half the depth of the hose. The scion seedlings are selected above the first leaf; where the inner stem is commensurate with the rootstock, cut off at an oblique angle of 30 degrees, right hand straighten the rootstock plant, and gently pinch the hose; hold the panicle lightly with the left hand; align the cuttings with the slant of the rootstock; insert the rubber casing down; gently push straight to ensure that the slant of the rootstock is fully connected.

Mechanical grafting

Mechanical grafting is different from artificial grafting, except that the action of taking seedlings, hanging seedlings and moving grafted seedlings into the hole plate is done manually, the other grafting processes are all completed by machinery. first of all, eggplant and tomato seedlings with a stem of about 2.2~3mm are used, eggplant seedlings are taken by the left hand, the stem is placed in the clamping clip of the left rootstock of the grafting machine, the left foot is pressed on the left pedal switch, and the tomato seedlings are taken by the right hand. Place the stem above the first leaf in the right ear wood clamping clip of the grafting machine, and press the right foot pedal switch to complete the ear wood clamping (if the action is skillful, the seedlings can be taken and hung by both hands at the same time), the grafting machine will automatically complete the grafting action, and the grafting seedlings will be sent out automatically, and the seedlings will be taken back and placed into the burrow plate manually.

The grafted seedlings should be placed in the health care room for about 2-3 days to heal, and then moved to the facility for about a week before they can be planted in the field. After planting, the grafting hose of the seedling falls off naturally due to the growth of the stem in the plant and the aging effect of sun exposure. there is no need to worry about artificial loosening, so it is more labor-saving than other grafting methods.
