Solidago canadensis Solidago canadensis belongs to the Asteraceae in the classification, SOLIDAGO (solidago l.). This is about 125 kinds worldwide, mainly distributed in North America, a small number of distribution in Europe and Asia; China has 4 species, both north and south; Zhejiang are two kinds, namely, Solidago canadensis (s. canadensis l., English canada goldenrop) and goldenrod (s. decurrens lour., the English common goldenrop). Because they are different species, can not be confused, it will be "Solidago canadensis" as "a flower" is incorrect. Solidago canadensis, also known as oriole, unicorn grass. These flowers are beautiful color, Canada imported flowers, the flower market to be called "happy grass", commonly used in flower arranging in with flowers. Solidago canadensis introduced in 1935 as an ornamental plant in China. Solidago canadensis is alien organisms, introduction of weeds after the Plaza generation, and is weed. Solidago canadensis is grown mainly in flood land, wasteland, roadsides, farmland side, surrounded by rural residential, plant height 1.5 m -3 meters. It is perennial, rhizome developed a very high reproduction, transmission speed, the growth of obvious advantages, vast ecological adaptation, fight the sun and the surrounding plants, fertilizer fight until the death of other plants, thereby posing a serious threat to biodiversity . Can be called off at the yellow grass, it is known as eco-killer, King spent. Solidago for the native plants, place a small amount, not common. The main difference between the two as shown below: Solidago canadensis rhizome was developed from the basic three pulse, positive very rough, conical flower heads arranged in inflorescences, was born in capitulum inflorescence branching side of Heliconia was like, all with a small achene pubescent, planted for ornament (trade name: oriole), malignant weeds, significantly more than the interests of the drawbacks for the elimination of the object. Solidago rhizomes absent or underdeveloped, veins pinnate and positive smooth, flower heads arranged in racemose inflorescence or cone Zhuang, born in capitulum inflorescence branches vain side was Heliconia not like, achenes smooth the top a little sparse sometimes pubescent, the whole plant medicine, general weed control and use of conventional objects. Solidago canadensis control methods are: 1. Burned. Cut off its spikes will pull out the stem above ground and massive, concentrated as soon as possible after the burning of these clean, prevent seeds, rhizomes and pull out some of the spread of proliferation. 2. Chemical control. Solidago canadensis in the flowering season and before and after emergence, the use of pesticides on plants to control, prevention and control of pharmaceutical major is: The "Roundup Ready" and "Fire" mixed spray before flowering; use of Roundup Ready and detergent the ratio of 5:1 were mixed in their seedling stage control; also be used for other Herbicide control. 3. Strengthen the management of green farmland.

Solidago canadensis Solidago canadensis is the classification of Asteraceae, Solidago genus (Solidago L.). This is about 125 kinds worldwide, mainly distributed in North America, a small number of distribution in Europe and Asia; China has 4 species, both north and south; Zhejiang are two kinds, namely, Solidago canadensis (S. canadensis L., in English Canada Goldenrop) and goldenrod (S. decurrens Lour., English Common Goldenrop). Because they are different species, can not be confused, it will be "Solidago canadensis" as "a flower" is incorrect. Are gymnosperms. Solidago canadensis, also known as oriole, unicorn grass. These flowers are beautiful color, Canada imported flowers, the flower market to be called "happy grass", commonly used in flower arranging in with flowers. Solidago canadensis introduced in 1935 as an ornamental plant in China. Solidago canadensis is alien organisms, introduction of weeds after the Plaza generation, and is weed.

Strengthen the management of green farmland. East China Normal University Resource Ecology and Environmental Science students more Zhe Li and his research team, after a year of observation found that the reed and the competition between the Solidago canadensis, and the reed is greater than the relative competitiveness of Solidago canadensis. Also found between the two species overlap greatly suitable living environment, the origin of the two species, regional climate and is very similar, and generally adapt to a variety of environments. In the calculation of niche overlap, the reed of Solidago canadensis in an upward trend of niche overlap, and Solidago canadensis niche overlap in reed decline, suggesting that the reed to the exclusion of Solidago canadensis range in its niche outside. Controlling the use of alternative control Solidago canadensis, compared to manual and mechanical control methods, the treatment cost is much smaller, and the effect of stability control, no damaging effects on the environment. The team plans further research to try to improve the use of alternative control method, so this approach really in the actual production work as expected.
