Problems solved by technology

Traditional propagation methods are difficult to meet the demand for Sanbai grass seedlings in different seasons in the market, which limits the application of Sanbai grass in urban gardens and other landscape projects to a certain extent.
[0005] This study found that under natural conditions, the aboveground part of Sanbai grass begins to wither 1-2 months after flowering, the leaves wither, the aboveground stems gradually become hollow and black, and finally dry and rot, waiting for the next spring to continue to germinate. This characteristic has not yet been specifically recorded.

Embodiment 1

[0037] On May 1, 2018, Sanbai grass was collected on the bank of the river in Nantang Village, Sihui City, Zhaoqing City, Guangdong Province. At this time, it is in the flowering stage and the growth is vigorous. Pull out the Sanbai grass seedlings with relatively consistent growth. The thickness of the main stem is about 1.5cm. ), remove all the leaves, and keep the dense section at the bottom, and use this as cuttings for hydroponic experiments. The water used for the test was pig farm breeding wastewater, which was filled in blue water tanks, with 60L of water per tank, and 15 cuttings of Sanbai grass, which were placed horizontally on the water surface to allow them to float and grow freely. The test period was from May 2 to June 5, 2018, for a total of 5 weeks. The growth of Sanbai grass was regularly observed every week, including the germination rate (number of germinated branches / total number of branches) and seedling height. The site is a simple greenhouse with light...

Embodiment 2

[0041] On August 1, 2018, Sanbai grass was collected on the bank of Nantang Village, Sihui City, Zhaoqing City, Guangdong Province. At this time, the flowers of Sanbai Grass have faded for about one month, and the top leaves appear slightly withered and yellow. Pull out the Sanbai Grass with a relatively consistent growth. About 30cm above the stem section), remove all the leaves, keep the dense section of the bottom node, and transplant it into the experimental field as a cutting in the evening (horizontally placed on the water surface in the paddy field). The test site is Nantang Village, Sihui City. The test field is a paddy field with a width of 1.5m. The ditch between the boxes is 30cm wide and 20cm deep. The row spacing is 40cm×30cm. There are 25 rows of compartments, a total of 2 compartments, and the depth of covering soil is 8-10cm. Half a day before transplanting, go to the test field to inject water in advance to make the soil moist and facilitate the insertion of ...

Embodiment 3

[0045] On August 15, 2018, the aboveground stems of Sanbai grass were collected on the bank of the river in Nantang Village, Sihui City, Zhaoqing City, Guangdong Province. At this time, the Sanbai grass has withered for about one and a half months, and the leaves at the top of the stem are slightly withered and yellow. Select a relatively delicate aboveground stem with a thickness of about 1cm, and cut off the stem section with a length of about 25cm at the base (that is, the stem from the base of the aboveground stem to about 25cm above the base. section), remove all the leaves, and keep the denser stem section at the base, and use it as cuttings to carry out cultivation experiments in the greenhouse of South China Botanical Garden, Chinese Academy of Sciences. The test period was from August 15th to September 12th, 2018, for a total of 4 weeks, and the growth of Sanbai grass was regularly observed every week, including the germination rate (number of germinated branches / total...

Abstract

The invention discloses a method for using aerial stems of saururus chinensis for rapid propagation. The method includes the steps of 1), taking the aerial stems of the saururus chinensis, retaining the densest stem segments where the surface of the soil meets the air, cutting main stems from 25-30cm near bases and removing most or all the leaves to obtain cuttings; 2), placing the cuttings horizontally in fertile water or a hoagland nutrient solution for floating water culture for 2-3 weeks to obtain new shoots; 3), transplanting the obtained new shoots horizontally into nutritive soil pre-sterilized for cultivation to obtain seedlings; 4), subjecting the obtained seedlings to individual propagation and transplanting the same in the field or planting bags for cultivation and planting. Themethod is at least three times more efficient than conventional vertical cutting, which is conductive to improving the propagation efficiency of the saururus chinensis and reducing the cost of cultivation and maintenance.

Description

technical field [0001] The invention belongs to the technical field of plant propagation, and in particular relates to a method for rapid propagation by utilizing the aboveground stems of Tribasmus chinensis. Background technique [0002] Saururus chinensis (Lour.) Baill.) is a perennial wet-growing herb of the family Salicaceae. About 1 meter high; the stem is strong, with long and thick ribs and grooves, the lower part is lying on the ground, often whitish, the upper part is erect and green. The leaves are papery, broadly ovate to ovate-lanceolate, 10-20 cm long, 5-10 cm wide, and the 2-3 pieces at the top of the stem are often white in flowering stage, in the shape of petals, very beautiful. The flowering period is from April to June, and the inflorescence is white, 12-20 cm long. The fruit period is July-August, the fruit is nearly spherical, about 3 mm in diameter, and has many verrucous protrusions on the surface. Produced in Hebei, Shandong, Henan and the Yangtze R...
