Embodiment 1

[0029]The time for cutting seedlings is early October. The height of the seedling sand bed is set to be 60cm from the ground, the width of the sand bed is 120cm, the depth is 50cm, and the length is 7m. Equilateral triangle, the mesh diameter of the mesh is 0.4cm; the surface of the mesh is paved with 10cm of pebbles, and then 20cm of river sand; 4 drip irrigation pipes are installed for each furrow, and 1 dripper is installed at an interval of 35cm. In the first ten days of November of the previous year, select camphor seedlings with seedling height ≥ 15cm, ground stem ≥ 0.26cm, strong growth, no pests and diseases, and plant them at a row spacing of 15×20cm. When it is lignified or lignified and the axillary buds on the branches are full and strong, they can be collected for cuttings. Firstly, the thick branches at the upper part are collected, and the branches at the base are collected after the lignification of the branches is strengthened by sunlight. Select strong bran...

Embodiment 2

[0031] The time for cutting seedlings is early November. Establish and set up a seedling sand bed that is 40cm high from the ground, 120cm wide, 50cm deep, and 5m long; the height difference between the two sides of the elevated sand bed is 1cm; set 8 mesh drains at the bottom of the lower side of the elevated sand bed, and the drains are star-shaped , the mesh diameter of the mesh is 0.5cm; the surface of the mesh is paved with 10cm of pebbles, and then 20cm of river sand; 3 drip irrigation pipes are installed for each furrow, and 1 dripper is installed at an interval of 35cm. In the first ten days of October of the previous year, select camphor seedlings with seedling height ≥ 15cm, ground stem ≥ 0.26cm, strong growth, no pests and diseases, and plant them at a row spacing of 15×20cm. When the axillary buds on the branches are full and strong, they can be collected for cuttings. Firstly, the thick branches at the upper part are collected, and the branches at the base are co...

Abstract

The invention discloses a cuttage rapid-propagation seedling culture method for elevated sand bed camphora wood cutting orchard tissue culture seedling twigs. The method comprises the following steps: taking semi-lignified twigs formed by camphora wood cutting orchard tissue culture seedling planted on the elevated sand bed as a cutting wood; treating the cutting wood by greenplant growth regulator-ABT6 rooting solution; inserting the treated cutting wood into a mixed medium which contains peat soil and coconut bran in a weight ratio of 3:(1-1.5); culturing on a pressure lifting seedling culture bed capable of automatically controlling temperature, controlling moisture and controlling light; controlling parameters of air humidity to 85%, medium moisture content to 50% and illumination intensity to 1500lux; and after one month, causing the cutting wood to form an integral plant, wherein the cuttage survival rate is 80-85%. The method has the advantages of scientific seedling culture facility, high propagation speed, large seedling culture amount, short seedling culture time, high afforestation survival rate, low wood culture cost, good economic benefit and social benefit and the like, offspring can keep the excellent hereditary character of a stock plant, and the asexual seedling culture of camphora fine variety is achieved.

Description

Technical field: [0001] The invention belongs to the technical field of asexual rapid propagation of plants, and relates to a method for rapidly propagating seedlings of tissue-cultured seedlings in an elevated sand bed camphor panicle nursery by cutting twigs. Background technique: [0002] Cinnamomum camphora (Cinnamomum camphora), also known as camphor and small-leaf camphora, is the main tree species for the production of natural aromatic oils in my country. It is a representative tree species of tropical and subtropical evergreen broad-leaved forests. Its distribution area is wide, at 10° to 34° north latitude , east longitude 88°~120°, mainly produced in Hainan, Taiwan, Fujian, Jiangxi, Guangdong, Guangxi, Hubei, Hunan, Sichuan, Chongqing, Yunnan, Guizhou, Zhejiang and other provinces and regions, with Fujian and Taiwan as the most. Camphor tree has a wide range of uses. Camphor and camphor oil can be extracted from roots, branches, leaves and seeds. Camphor wood is an ...
