Method for grafting tomato casing with stem segments

Abstract

The invention discloses a method for grafting a tomato casing with stem segments. The method is characterized in that in grafting, apical buds and the stem segments are respectively selected to be used as scions directly according to the height of the scion seedlings and the number of leaves, 1-2 true leaves can be reserved for each stem segment, and 2-3 scions can be taken for each plant; a cutting blade is firstly used to cut the position obliquely upward at an angle of 35-45 degrees at the distance of 6-7cm from the base of hypocotyl of selected rootstock, the cut surface is flat and smooth, and a soft casing is inserted in the top of the cut surface of the rootstock so that the lower portion of the cut surface of the rootstock is at the middle height of the soft casing; scion seedlingswith the same diameter as the rootstock are selected from the scions and are cut obliquely downward in the position of the hypocotyl at the angle of 35-45 degrees, and the cut surfaces of the selected scion seedlings are inserted in the soft casing to make the two oblique sections of the rootstock and the scions meet closely to obtain the tomato grafting seedlings. The method has the advantages that the apical buds of the tomatoes and the cut stem segments are used for casting grafting, 1 seed can form 2-3 scions, breeding cost is low, grafting is fast and the survival rate is high.

Description

technical field [0001] The invention belongs to the vegetable grafting technology, in particular to a method for grafting tomato casings by using stem segments. Background technique [0002] Tomato is one of the main overwintering vegetable varieties in southern Zhejiang. The area has exceeded 50,000 mu, and the industrial foundation is strong. Due to factors such as continuous cropping obstacles, soil-borne diseases are very serious and have become the main limiting factor affecting tomato cultivation in facilities. Grafting is an effective method to alleviate continuous cropping obstacles. It has been widely used in production. At present, the price of tomato seeds is very high. The high seed cost of scion grafting technology of tomato one seedling and one bud is not conducive to the development of the industry. Based on the practical experience in recent years, the author has explored a set of grafting seedling cultivation technology using tomato stem segments, which can ...

[0002] Tomato is one of the main overwintering vegetable varieties in southern Zhejiang. The area has exceeded 50,000 mu, and the industrial foundation is strong. Due to factors such as continuous cropping obstacles, soil-borne diseases are very serious and have become the main limiting factor affecting tomato cultivation in facilities. Grafting is an effective method to alleviate continuous cropping obstacles. It has been widely used in production. At present, the price of tomato seeds is very high. The seed cost is too high due to the scion grafting technology of one tomato seedling and one bud, which is not conducive to the development of the industry.
