Problems solved by technology

However, the seeds of the fragrant fruit tree are small, the germination period is long, and the cotyledon growth period is as long as 2 months. Field seedlings often face fierce competition from vicious weeds and infection by deadly pathogens. The dual threats of weeds and pathogens lead to emergence The low rate and preservation rate have become the main obstacles to conventional seedling cultivation

Embodiment 1

[0031] From February to May 2018, an experimental forest farm in Jiangsu Province carried out a seedling cultivation experiment of fragrant fruit trees, and the provenance came from Wufeng County, Yichang, Hubei. The specific experimental steps are as follows:

[0032] (1) Build a cultivation pool: choose Ximen Nursery, which has a flat terrain and is leeward to the sun, as a nursery site, and build the pool body with red bricks and cement according to the pre-designed size; figure 1 As shown, the building height of the pool wall 10 is 65cm, and the thickness of the pool wall 10 and the pool bottom 8 is 18cm. The pool wall and the pool bottom are built with red bricks, and the exterior is ground with cement; Drainage holes 5 are set with a diameter of 5 cm; the bottom of the pool 8 is provided with a filter cushion 6 made of silica sand permeable bricks, and the size of the silica sand permeable bricks is 200mm×100mm×55mm; the inner wall of the pool wall 10 is equipped with a ...

Embodiment 2

[0041] From February to May 2018, a seedling cultivation test of fragrant fruit trees was simultaneously carried out in an experimental forest farm in Jiangsu Province, and the provenance was the same as in Example 1. And according to the specifications in the implementation step (2) in Example 1, the culture tank was built, and the matrix was spread and sterilized according to the steps (2)~steps (3) in the pool; carried out on March 8 The seedbed was sown, and then the seedbed was artificially sprayed with water, leveled, suppressed, and covered with film. During the seedling cultivation period, the environment of the seedbed was inspected and monitored every day; 28 days after sowing, the seeds began to germinate, and the radicle was exposed, and the germination rate reached 65% in 40 days, and true leaves gradually grew after 50 days; after germination, the number of weeds in the seedbed was not high Many, 16 to 24 plants per square meter, and the infection rate of sprouts...

Abstract

The invention discloses a method for cultivating bud seedlings of emmenopterys henryi. The method includes steps of cultivation pond building, substrate filling and laying, disinfecting and sterilizing, seed sowing and leveling, arch shed erecting, conditional sunshade and later-period management and protection. The method has the advantages that the technical difficult problems of long cultivation periods and disease susceptibility of existing bud seedlings, strict requirements on seedling bed environmental conditions and difficulty in controlling weed breeding in seedling growing productionpractice on emmenopterys henryi at present can be pertinently solved by the aid of the full-protection, precision-management, joint-control and synergistic technical method for cultivating the bud seedlings, the shortcomings of the traditional technologies for growing seedlings can be effectively overcome by the aid of technical means of the method, mildew and rot of seeds can be reduced, bud seedling suffocation can be relieved, viable seeds of the emmenopterys henryi can assuredly germinate as quickly as possible, and the method is favorable for saving the production cost and improving the seedling growing efficiency.

Description

technical field [0001] The invention belongs to the field of forestry seedling cultivation and planting, and in particular relates to a method for cultivating fragrant fruit tree sprouts. Background technique [0002] Emmenopterys henryi belongs to Rubiaceae (Rubiaceae), one of the surviving relict plants of Quaternary glaciers, and a unique single-species plant in China. The materials are national second-level key protected plants and national precious tree species announced by the former Ministry of Forestry. This species is mainly distributed in deciduous broad-leaved forests or evergreen and deciduous broad-leaved mixed forests in the northern subtropical and mid-subtropical regions of my country, and often exists as an associated tree species. The trunk of the fragrant fruit tree is tall, with white flowers welcoming summer and red fruits sending autumn. The flowers are large and colorful, and are extremely rare. They are suitable for garden greening, park decoration, ...
