Embodiment 1

[0024] Dongying City Guangbei Farm Forage Test Base, the test area is 300m 2 , soil pH value 7.9, available nitrogen 46mg / kg, organic matter 30.6g / kg, soil salt content 0.27%.

[0025] In Example 1, the stem section of Swertia chinensis was collected from the pasture test field of Guangbei Farm in Dongying City, which is adjacent to the natural grassland plot in the east. The wild plants in this plot are mainly roegrass, accompanied by plants such as reeds, imperatas, and tamarisks.

[0026] A method for propagating roe chinensis by stem cuttings, the steps are as follows:

[0027] (1) Level the plot where the cuttings are to be cut, and then plow and rake it finely. The plowing depth is 20cm, and the water is flooded to make the soil moisture content reach 20%.

[0028] (2) On May 10, 2010, select roe chinensis branches with a stem thickness of 1.8-2mm, and cut off a stem section with a length of 6-7cm, and each stem section does not have a stem node with side buds to obtai...

Embodiment 2

[0045] Jinan Shanghe Grass Experiment Base, with an area of ​​300m2 2 , soil pH value 7.5, soil salt content 0.34%, available nitrogen 53.2mg / kg, available phosphorus 62.3mg / kg, organic matter 0.92%.

[0046] In Example 2, the stem section of Swertia chinensis was collected from the natural pasture plot in the Shanghe Pasture Grass Experimental Field. The wild plants in this plot are dominated by Swertia chinensis, accompanied by plants such as Phragmites spp.

[0047] A method for propagating roe chinensis by stem cuttings, the steps are as follows:

[0048] (1) Level the plots where the cuttings are to be cut, and then plow and rake them finely. The plowing depth is 20cm, and the water is flooded to make the soil moisture content reach 15% to 20%.

[0049] (2) On May 20, 2010, select the roewort branches with a stem thickness of 1.2-1.5mm, and cut off the stem segments with a length of 6-7cm. Each stem segment has a stem node with side buds, and the cuttings are prepared ...

Embodiment 3

[0066] Forage Test Base in Licheng District, Jinan City, with a test area of ​​300m 2 , soil organic matter 1.34%, total nitrogen 1.42g / kg, available phosphorus 51.00mg / kg, available potassium 141.00mg / kg.

[0067] In Example 3, the stems of Swertia chinensis were collected from natural pasture plots in the forage test field in Licheng District, Jinan. The wild plants in this plot are dominated by Swertia chinensis, accompanied by plants such as Phragmites spp.

[0068] A method for propagating roe chinensis by stem cuttings, the steps are as follows:

[0069] (1) Level the plots where the cuttings are to be cut, and then plow and rake them finely. The plowing depth is 15cm, and the water is flooded to make the soil moisture content reach 15% to 20%.

[0070] (2) On May 10, 2011, select roe chinensis branches with a stem thickness of about 1.5-1.8 mm, and cut stem segments with a length of 9-10 cm. Each stem segment has a stem node with side buds, and the prepared stem cutt...

Abstract

The invention relates to a method for utilizing stem section cuttage to propagate aeluropus. The method comprises turf-bed preparation, stem section selection, cuttage and field management. Cuttage of cuttage stem sections is carried out with the line spacing no smaller than 20cm and planting distance no smaller than 10cm, each stem section is contacted with the soil and pressed into the soil for 3-5cm, soil moisture is preserved to keep a full stand of seedlings, watering is performed to enable soil moisture content to be 15%-20%, the soil moisture content is maintained, and field management is carried out after 1-2 blades of stem section lateral buds grow out. The method enables cuttage survival rate to be over 80%, is simple and convenient to operate, does not damage wild environment of the aeluropus, is low in cost, enables rapid planting to be achieved, and has wide application prospect.

Description

technical field [0001] The invention relates to a method for propagating roe chinensis by stem cuttings, and belongs to the technical field of wild plant breeding. Background technique [0002] Aeluropus lttoralis var. sinensis is an excellent wild plant resource with strong drought and saline tolerance. It is mainly distributed in saline-alkali tidal flats in Shandong, Liaoning, Hebei, Jiangsu, Heilongjiang, Jilin and other provinces in China, Inner Mongolia , Gansu also has a small amount of distribution. The natural grassland with Swertia chinensis as the building species is an important agricultural and animal husbandry resource, which can be used not only for grazing, but also for natural grassland cutting, and the value of animal husbandry is relatively prominent. In addition, Swertia chinensis is also an excellent herbaceous plant for soil-fixing and slope protection. It has the characteristics of strong resistance, fast creeping growth, short formation time, and goo...
