Embodiment Construction

[0025] The following is a further detailed description of the present invention in conjunction with the embodiments, so that those skilled in the art can implement it with reference to the description.

[0026] It should be understood that terms such as "having", "comprising" and "including" as used herein do not entail the presence or addition of one or more other elements or combinations thereof.

[0027] The present invention provides a kind of open arrow cutting propagation method, comprising:

[0028] Step 1. Cut the open arrow stalk into 2cm cutting segments, each cutting segment contains at least one internode;

[0029] Step 2. Soak the base of the cutting section in the rooting agent for 5-10 seconds, then take it out and dry it in the shade;

[0030] Step 3. Water the cutting substrate one day before cutting to make the cutting substrate fully moist, insert the base of the cutting section into the cutting substrate, so that 1 / 3 of the cutting section is exposed outsi...

Abstract

The invention discloses a Tupistra chinensis Baker cutting propagation method including the following steps of: cutting Tupistra chinensis Baker stems into small cutting sections 2cm long; soaking bases of the small cutting sections in a rooting agent; inserting the bases of the small cutting sections in a cutting medium; for the first day to the 30th day, keeping the day temperature of 20-30 DEG C, the night temperature of 15-20 DEG C and the air humidity of 80-90%, covering the small cutting sections by using a sunshade net with a sunshade rate of 85%-90%, and watering the medium at regular intervals; for the 31th day to the 60th day, keeping the air humidity of 70-80%; for the 61th day to the 90th day, covering the small cutting sections by using a sunshade net with a sunshade rate of 70-80%; and when the root strip length of the small cutting sections is 4-6cm and the leaf length is 5-10cm, transplanting cutting seedlings into large farmland. The Tupistra chinensis Baker cutting propagation method ensures that bred plants can stably keep mother plant characters. The cutting survival rate is high and the survival rate can reach more than 95%. The breeding time is shortened.

Description

technical field [0001] The invention relates to a cuttage propagation method of an open arrow. Background technique [0002] The breeding method of open arrow is generally sowing propagation. But sowing and breeding also has its limitations, the cycle is long, and the source of provenance is required. Cutting breeding has the advantages of short time, easy access to breeding materials, and stable retention of the traits of the mother plant. Open arrow cutting propagation has not been reported in the literature. Contents of the invention [0003] It is an object of the present invention to solve at least the above-mentioned problems and to provide at least the advantages which will be described later. [0004] Another object of the present invention is to provide a cutting propagation method of open arrow, which not only improves the survival rate of cuttings, but also has a short cycle. [0005] In order to realize these purposes and other advantages according to the p...
