Quick grafting propagation method for syzygium samarangense

Abstract

The invention belongs to the technical field of grafting propagation of woody plants, and particularly relates to a quick grafting propagation method for syzygium samarangense. The quick grafting propagation method includes, in the early spring, before sprouting, selecting strong branches on the middle and upper portion of the crown of the stock plant of syzygium samarangense, selecting 2-3 years old syzygium samarangense seedlings, which are not germinated, with ground diameter equal to or greater than 2cm, as rootstocks, cutting off the rootstocks at the position 5cm away from the ground, and then perpendicularly ripping along the cross sections of the rootstocks, wherein the cutting depth is nearly equal to or slightly shorter than the long sections of scions, the cut width is nearly equal to that of the scions, and the cut length is equal to 4cm; making a big section with the length equal to 4cm under the 2-3 buds of the remained branches, and then making a small section with the length equal to 1-2cm; inserting the cut scions into the cuts of the rootstocks immediately while exposing the edge of 0.5cm, applying hormone, and finally binding the grafted positions and the cuts of the scions by plastic strips tightly, with only 1-2 buds exposed. The quick grafting propagation method for syzygium samarangense has the advantages of high grafting survival rate and short culture cycle of grafted seedlings, and further, is convenient to operate, easy to learn and suitable to popularize.

Description

technical field [0001] The invention belongs to the technical field of grafting and propagation of woody plants, and in particular relates to a rapid grafting and propagation method of lotus mist. Background technique [0002] Lotus mist (Syzygium samarangense Merr. & Perry), also known as foreign apples, Jinshan apples, Myrtaceae rose apples, tropical evergreen trees, native to Malaysia and India. Lianwu tree has beautiful posture, luxuriant branches and leaves, beautiful flower shape, bright fruit color, long flowering and fruit-hanging period, and high ornamental value. It is an excellent tree species for garden greening and community greening. The excellent variety of Lianwu has fast growth speed, early results, high yield, good fruit quality and rich nutrition. It is also a famous tropical fruit. my country's Taiwan, Guangdong, Guangxi, Hainan, Fujian and other provinces and regions have cultivation, among which the cultivation area in Taiwan is the largest.
