Description

Watermelon seedling grafting device

Technical Field

The utility model relates to the technical field of watermelon seedling grafting, in particular to a watermelon seedling grafting device.

Background

Watermelon is a dicotyledonous flowering plant, and is shaped like a vine, and leaves are in a feather shape. The fruit it yields is a false fruit and belongs to the class of botanicals known as false berries. The outer skin of the fruit is smooth, green or yellow, and has patterns, and the pulp juice is red or yellow (rare white). Is one of the favorite fruits in summer. Grafting is one of the artificial propagation methods of plants. That is, the branches or buds of one plant are grafted onto the stems or roots of another plant, so that the two parts grafted together grow into a complete plant. At present, three methods of grafting watermelons are mainly used, namely grafting, split grafting and abutting grafting, and grafting is also called top beating grafting. The method is simple, has high work efficiency, does not need to bind up interfaces, and saves labor and materials. When in grafting, bamboo sticks (the thickness of which is similar to that of the hypocotyls of the scions and cut into a wedge shape) are used for vertical grafting downwards along the growth points to form a socket, and then watermelon seedlings are inserted into the socket to realize scion work.

The bamboo sticks are adopted for inserting, the size of the lower port diameter of the bamboo sticks is limited, the adjustment cannot be carried out, the insertion holes with the needed caliber cannot be inserted into the top of the stem, and certain influence is caused on grafting work.
