example 1

[0037] The cuttings were carried out in May 2012, and the cuttings were collected from the branches of the 3-year-old black wattle saplings. Both coconut bran and tung bran substrate materials were fermented in the previous year and fully decomposed. The proportion of the light substrate is 50% fully decomposed coconut peat, 20% carbonized sawdust, 20% fermented tung bran, and 10% perlite. Cut the cuttings into 10cm-12cm cuttings, soak them in clean water for 2 hours after cutting them, take them out and put them in 1:1500 times carbendazim aqueous solution and soak them for 8 minutes, rinse off the residual medicinal liquid with clean water; before cutting Immerse the 1cm-1.5cm base part of the cuttings in 2000ppm indole butyric acid solution for 20s, keep stirring, and then cut the cuttings. After the cuttings, build an arch shed with a height of 45 cm on the seedbed, seal the seedbed with plastic film, and cover it with a sunshade net with a shading rate of 75%. Open the ...

[0040]Cuttings were carried out in May 2012, and the cuttings were collected from the branches of the 2-year-old black wattle seedlings in the same year. Both coconut bran and tung bran substrate materials were fermented in the previous year and fully decomposed. The proportion of light substrate is fully decomposed coconut peat: 45%, carbonized sawdust 18%, fermented tung bran 30%, perlite 7%. Cut the cuttings into 10cm-12cm cuttings, soak them in clean water for 3 hours after cutting them, take them out and put them in 1:1500 times carbendazim aqueous solution and soak them for 10 minutes, rinse off the residual medicinal liquid with clean water; before cutting Immerse the 1cm-1.5cm base part of the cuttings in 2000ppm indole butyric acid solution for 30s, keep stirring, and then cut the cuttings. After the cuttings, build an arch shed with a height of 55cm on the seedbed, seal the seedbed with plastic film, and cover it with a sunshade net with a shading rate of 75%, keep ...

[0043] Cuttings were carried out in June 2012, and the cuttings were collected from the branches of the 2-year-old black wattle seedlings in the same year. Both coconut bran and tung bran substrate materials were fermented in the previous year and fully decomposed. The light substrate is 55% fully decomposed coconut peat, 15% carbonized sawdust, 25% fermented tung bran, and 5% perlite. Cut the cuttings into 11cm cuttings, soak them in water for 4 hours after cutting them, take them out and put them in 1:1500 times carbendazim aqueous solution and soak them for 9 minutes, rinse off the remaining medicinal liquid with water; The 1cm to 1.5cm long part of the base of the strip is immersed in 2000ppm indole butyric acid solution for 20s to 30s, without constant stirring, and then cuts. After the cuttings, build an arch shed with a height of 50 cm on the seedbed, seal the seedbed with plastic film, and cover it with a sunshade net with a shading rate of 75%. Keep the temperature i...

Abstract

The invention discloses a black wattle light medium container cutting seedling method which comprises four steps of cutting medium preparation, scion wood collection and processing, cutting and management after cutting, wherein the medium is prepared by the following raw materials in volume percent: 45 to 55 percent of coco coir, 10 to 20 percent of carbonize saw dust, 15 to 30 percent of fermented tung bran, and 5 to 10 percent of perlite; the light medium is sterilized through 40 percent of methyl aldehyde before cutting; the cutting scion is processed by sterilizing agent and rooting agent after being soaked by clean water for 2 to 4 hours; the seedling is cultivated under the environmental condition that the water content of the medium is 50 to 70 percent, the temperature is 20 DEG C to 28 DEG C, and the relative humidity is above 85 percent. The method provided by the invention has the advantages that the physical behavior of the light medium is better, and is more suitable for the growth and development of plant root system; the light medium of the un-survived plant can be recycled, and the medium is light in weight, so that seedling cultivation cost, transportation cost and forestation cost are reduced; according to the cutting seedling method provided by the invention, survival rate is improved, and healthy plantlets with high quality are cultivated.

Description

technical field [0001] The invention relates to a method for asexual propagation of black wattle, in particular to a method for rapid propagation of black wattle light-substrate container cutting seedlings. Background technique [0002] Black wattle (Acacia mearnsii De Wilde), also known as Australian Acacia, is native to Australia and South Africa. It was introduced in my country in the 1950s and is currently mainly distributed in Fujian, Zhejiang, Jiangxi, Guangdong, Guangxi, Yunnan, Guizhou and other places. Black wattle is a world-renowned fast-growing, high-yielding, high-quality tannin tree species. It has the reputation of "forestry black gold". Cancer cells, etc. have obvious inhibitory effect. [0003] At present, black wattle mainly cultivates seedlings for afforestation through seed propagation, and there are also a small number of reports on cutting seedlings with yellow heart soil as the substrate. However, there are many black wattle families, and the tannin ...
