Problems solved by technology

There are very few research reports on the seedling propagation of syringa in the existing literature, and there is only a brief description of the cutting propagation technology of syringa spp., and the survival rate is not high. To a certain extent, there is an urgent need to propose a simple, cheap and effective asexual reproduction method to meet the production needs

Embodiment 1

[0021] (1) Seedbed preparation: In June 2012, the cutting experiment of A. chinensis was carried out in Jiangsu Academy of Forestry Science, Nanjing, Jiangsu. The soil has been carefully and deeply plowed, and debris such as grass roots, stones, and plastics have been removed.

[0022] (2) Soil disinfection: The soil was strictly disinfected 10 days before the cutting, that is, the soil was disinfected by mixing medium-coarse sand, 70wt% pentachloronitrobenzene wettable powder and loess (mass ratio 1:1:9) The matrix is ​​sterilized. Spread the substrate evenly on the seedbed with a thickness of 2-3cm, moisten it with tap water and set aside for use.

[0023] (3) Selection and pruning of cuttings: Select vigorously growing, semi-lignified 1-year-old branches as cuttings. When cutting, keep the fringe length 5-6cm, with 2-3 buds, the incision is flat, the upper incision is 1cm away from the upper bud, and the lower incision 0.5cm away from the lower bud.

[0024] (4) Root-pro...

Embodiment 2

[0031] In June 2012, the cutting experiment of Yanfu arborina was simultaneously carried out in the Jiangsu Academy of Forestry Sciences. According to the steps (1)-(2) in this example 1, the soil of the seedling field was disinfected; the cuttings were selected and cut according to the above-mentioned step (3); after the cuttings were prepared, they were soaked in tap water for 6-12 hours and then inserted directly On the pre-prepared cutting bed, the depth of burial is 1 / 3-1 / 2 of the length of the cuttings, and the density is 2cm×4cm. Thoroughly spray and sterilize the cuttings with thiophanate-methyl solution, and insist on spraying and sterilizing with thiophanate-methyl solution every 7 days after cutting. The results showed that there were few rotten roots of the cuttings, but the roots of the cuttings began to produce callus 15 days after planting, and roots began to take root after 20 days. After 25 days, the rooting rate was 60.3%, and the average root length was 4.7 ...

Abstract

The invention discloses a cutting seedling method of cornus stolonifera. The key technology steps of the method include seedbed preparation, matrix blending, soil sterilizing, cutting slips selecting and cutting, root promoting, cuttage and sterilization, film mulching temperature control and moisture retention, management after cuttage and seedling transplanting. By means of the method, the vegetative propagation survive rate of the cornus stolonifera is remarkably improved, the cuttage survival rate reaches to above 92%, qualified seedlings are cultivated to the hilt on the premise of limited seedling growing field and seedling quantity through careful cultivation and effective management, the seedling cost is lowered, and the seedling raising efficiency is increased.

Description

technical field [0001] The invention relates to a method for raising seedlings by cuttings of arboria chinensis, and belongs to the technical field of forest tree seedling propagation. Background technique [0002] In botanical taxonomy, the genus Cornus belongs to the genus Cornus (Cornus) of the family Cornaceae, and is a deciduous shrub. Leaves gray-green, branches red, 90-120cm high. Flowers are yellowish white, often open in late spring or early summer. Flowering period from May to June, drupe, white. Native to the Sierra Nevada in the United States to Siskiyou, Trinity, New Mexico and Alaska, and Newfoundland in Canada. Domestic and foreign literature shows that this species has beautiful shape, luxuriant branches and leaves, flowers in summer and fruits in autumn, and has strong adaptability. It is an excellent tree species for landscaping and soil and water conservation, and is also an excellent material for weaving industry. Northeast my country had a small amou...
