Embodiment 1

[0021] On May 5, 2010, on the five-year-old fruiting mother plant, cut the semi-lignified branches of Lianwu, cut them into 20-25cm long cuttings with 3 buds, and leave a complete leaf at the top. The lower end of the cuttings is about 2cm long Dip it into GGR-6 rooting powder paste, insert it into a 8×20cm plastic nutrition bag, the cutting depth is 1 / 3 of the cutting length, the substrate is prepared by mixing 90% yellow heart soil and 10% river sand, and manage normally, cutting 100 plants , 77 plants took root and survived, with a survival rate of 77%. On March 12, 2011, the young rose apple seedlings with a height of 80-100cm and a ground diameter of 0.6-1cm were transplanted from the nursery with a soil mass, and moved into a 15×20cm plastic nutrition bag. The transplanting medium was mixed with 80% fertile topsoil and 20% plant ash. preparation. On the afternoon of July 13, 2011, the cutting seedlings of lotus mist were grafted with rootstocks of rose apples, and 77 pl...

[0023] On June 3, 2012, on the five-year-old fruiting mother plant, cut the semi-lignified branches of Lianwu, cut them into 20-25cm long cuttings with 3 buds, and leave a complete leaf at the top. The lower end of the cuttings is about 2cm long Dip it into GGR-6 rooting powder paste, insert it into a 8×20cm plastic nutrition bag, the cutting depth is 1 / 3 of the cutting length, the substrate is prepared by mixing 90% yellow heart soil and 10% river sand, and manage normally, cutting 100 plants , 70 plants took root and survived, with a survival rate of 70%. On April 28, 2013, the young rose apple seedlings with a height of 80-100cm and a ground diameter of 0.8-1cm were transplanted from the nursery with a soil mass, and moved into a 15×20cm plastic nutrition bag. The transplanting medium was mixed with 80% fertile topsoil and 20% plant ash preparation. On August 18, 2011, the cutting seedlings of lotus mist were grafted with rootstocks of rose apples, and 70 plants were graft...

Abstract

The invention discloses a cuttage grafting propagation method of Syzygium samarangense. According to the method, on the basis of Syzygium samarangense cutting seedling raising, inarching is carried out with Syzygium jambos Alston seedlings serving as grafting stocks with combination of interspecific grafting, and efficient Syzygium samarangense nursery stock propagation is achieved through steps like Syzygium samarangense cutting seedling raising, Syzygium jambos Alston stock cultivation, interspecific inarching and follow-up management. According to the inarching step, Syzygium samarangense cutting seedlings are in one-to-one correspondence to the Syzygium jambos Alston stock seedlings, and the Syzygium samarangense cutting seedlings and grafting seedlings are cultivated at the same time; two types of Syzygium samarangense container seedlings can be obtained after the inarching process, wherein one type of container seedlings are biennial cutting seedlings with the height ranging from 40cm to 50cm, and the other type of container seedlings are annual grafting seedlings with the height ranging from 30cm to 45cm. Compared with a method where only cutting seedling raising is adopted or a traditional grafting seedling raising method, seedling propagation efficiency can be improved by more than one time by adopting the cuttage grafting propagation method, and the cuttage grafting propagation method has the advantages that the grafting survival rate is high and can reach 100%, nursery stock quality is high, and remarkable economical benefits are achieved.

Description

technical field [0001] The invention belongs to the technical field of grafting and propagation of woody plants, and in particular relates to a cutting 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.
