Embodiment Construction

[0027] One, below in conjunction with specific embodiment, further set forth the present invention:

[0028] 1. Picking time

[0029] The cutting time is chosen in October, mainly because there are more nutrients stored in the branches during this period, and as the temperature decreases, the evaporation is reduced, which is conducive to the survival of cutting branches.

[0030] 2. Slotting bed preparation and cutting environment

[0031] Spread the cutting substrate (river sand) on the concrete floor and expose to the sun for 2-3 days to kill the pathogenic bacteria in the substrate. After two layers of sunshade nets are placed in the plastic basket, the treated river sand is filled to two-thirds (the thickness of the substrate is about 30cm), placed in the sunshade shed, and watered thoroughly for later use. The use of river sand matrix can avoid the rot of the spikes caused by stagnant water, and the air permeability is also better.

[0032] 3. Selection of cuttings and...

Abstract

The invention discloses a method for carrying out asexual cuttage propagation on vernicia fordii, belonging to the technical field of asexual propagation of plants. The method comprises the following steps of: (1) branch collecting time; (2) seedbed preparation and cuttage environment; (3) selection of cuttings and treatment of cutting branches; (4) pretreatment of a growth regulator; (5) cuttage; and (6) management after cuttage. The method provided by the invention is simple and feasible, has the advantages of low cost and short cycle and can conduce to realization of effective and rapid asexual propagation of the vernicia fordii. The method has the beneficial effect of solving the problem that the vernicia fordii can not root during cuttage, and has very important effects on and significance for accelerating popularization of excellent clone of the vernicia fordii and promoting construction of biodiesel raw material forests.

Description

technical field [0001] The invention belongs to the technical field of plant vegetative propagation, and in particular relates to a tung tree vegetative cutting propagation method. Background technique [0002] Tung ( Vernicia Fordii ) belongs to Euphorbiaceae ( Euphorbiaceae ) Tung (Vernicia ), deciduous trees. Tung tree grows fast, results early, and has high yield. The full fruit period can reach 20 to 30 years, and the small-area fresh fruit yield per mu can reach 1000 to 2000Kg during the full fruit period. The oil content of the seed kernel can be as high as 70%. Tung oil contains stearic acid, oleic acid, linoleic acid, linolenic acid and tung acid. It has great potential to develop second-generation biodiesel with tung oil. [0003] At present, the tung tree propagation method is to obtain seeds through sexual reproduction, and then sow and raise seedlings. But tung oil is a typical cross-pollinated plant, the genotype of the plant is highly heterozygous, the ...
