specific Embodiment 1

[0031] A cutting propagation method of Fructus hainanensis, comprising the following steps:

[0032] Selecting good growing and natural distribution community adult False Shaozi as the cuttings for testing mainly includes the following steps:

[0033] (1) Experimental site conditions: The nursery where the cuttings of Hainan Fructus Shaozi are located needs a shade shed, and the light transmittance of the shade shed is adjusted to 50% to 60% through the sunshade net; the temperature of the greenhouse is adjusted to 25°C to 25°C through the greenhouse air conditioner and sprinkler irrigation system 35°C;

[0034] (2) Cutting of cuttings: the cuttings are processed to make the cuttings 14cm-16cm long and 0.1cm-0.3cm in diameter. Soak the cuttings for 15 minutes to achieve the effect of sterilization;

[0035] (3) Soil matrix treatment: The soil matrix of the cutting site is made by mixing humus peat matrix and perlite at a ratio of 1:1, and disinfected with 3‰ potassium perman...

specific Embodiment 2

[0039] A cutting propagation method of Fructus hainanensis, comprising the following steps:

[0040] Selecting good growing and natural distribution community adult False Shaozi as the cuttings for testing mainly includes the following steps:

[0041] (1) Experimental site conditions: the nursery where the cuttings of F. hainanensis is located needs a shade shed, and the light transmittance of the shade shed is adjusted to 55% through the sunshade net; the temperature of the greenhouse is adjusted to 30°C through the greenhouse air conditioner and sprinkler irrigation system;

[0042] (2) Cutting of cuttings: treat the cuttings so that the cuttings are 15cm long and 0.2cm in diameter, cut the cuttings at the top and obliquely at the bottom, and then soak the cuttings with 1% carbendazim for 15 minutes , to achieve the effect of sterilization;

[0043] (3) Soil matrix treatment: The soil matrix of the cutting site is made by mixing humus peat matrix and perlite at a ratio of 1...

Embodiment 1

[0047] The experiment was carried out in the greenhouse of Sanya Academy of Forestry Sciences, Hainan Province, and two kinds of cutting seedling substrates were used for cutting seedling raising:

[0048] (1) V coconut peat matrix: V perlite = 1: 1 mixed, denoted as S1;

[0049] (2) V pastoral soil: V river sand = 2:1 mixed, denoted as S2,

[0050] The above two soil substrates were sterilized by 3‰ potassium permanganate solution, and 10 cuttings were cut in each nutrient cup.

[0051] (1) Experimental design: After soaking 1% carbendazim for 15min in the cuttings of Fructus hainanensis, ABT rooting powder and digil- Two kinds of hormones such as GGR were treated for 4 hours, and then the cutting test was carried out. Treated with deionized water as the control group. Three repetitions were set up for each treatment group, each repetition had 90 cuttings, and the observation time was 30 days after cuttings.

[0052] (2) Results: as shown in Table 1 below:

Abstract

The invention discloses a cuttage propagation method for Paranephelium hainanensis. The cuttage propagation method comprises a series of management steps such as test plot condition selecting, cuttingshearing, soil matrix treatment, hormone treatment, cuttage and later stage management. The cuttage propagation method is simple in operation and obvious in effect, a scientific basis is provided forprotection and sustainable utilization of the Paranephelium hainanensis, the population quantity of the Paranephelium hainanensis is enlarged, and the difficulty of the Paranephelium hainanensis thatthe seed quantity is small, the percentage of germination is low, and the like is solved.

Description

technical field [0001] The invention relates to the technical field of cutting seedling breeding, in particular to a cutting breeding method of Fructus hainanensis. Background technique [0002] Hainan false Shaozi (Paranephelium hainanensis) is an evergreen tree species of Sapindaceae, which is endemic to my country and is distributed in Ya County, Hainan Island. Due to the extremely rare number of plants and narrow distribution area, it is listed as my country's second-class rare and endangered plants and national key protected wild plants (the first batch), and is also listed as a critically endangered species by IUCN. Hainan False Shaozi is naturally regenerated and hard, so it is difficult to regenerate. Its big trees and old trees are decreasing day by day, and are already on the verge of extinction. The research on F. hainanensis focused on the chemical composition of the fat-soluble volatile part of leaves, community ecology and soil characteristics, but the resear...
