一枝黄花

If you come across a large field of goldenrod like this, you probably won't be far off to say it's a field of Canada Goldenrod.

如果你跨过一片像这样的黄花地，你不大会不说，这就是加拿大一枝黄花地。

Solidago canadensis in the course of the investigation found that the growth in intensive Solidago canadensis-growing areas, underground almost no other weeds.

在对加拿大一枝黄花的调查过程中发现，在生长密集的加拿大一枝黄花生长区，地下几乎找不到其他杂草。

Any of numerous chiefly North American plants of the genus Solidago, having clusters of small yellow flower heads that bloom in late summer or fall.

一枝黄花许多主要产于北美的一枝黄花属植物，簇生成头状花序的小黄花，在夏末和秋季开花

Our results indicate that there is a significant spatial heterogeneity of Solidago canadensis areal distribution in the study area. Imports and intensity of agricultural activities are major factors in Solidago canadensis occurrence area, while length of highways accounts for the variance in relative area of Solidago canadensis.

结果表明：加拿大一枝黄花在浙江省的分布存在明显的空间异质性；进口货物总额与农业活动强度是解释加拿大一枝黄花发生面积变异的主要因子；境内公路里程是解释加拿大一枝黄花发生面积比例变异的主要因子。

ML^(-1);(2) The allelopathic effects of the leaves and inflorescences of Solidago canadensis on these three crops are strong than those from the stems;(3) Among these three crop species, the seed of Brassica chinensis var. communis is more sensitive to the water extract of Solidago canadensis than those of Capsicum annuum, Lycoperiscum esculetum.

mL^(-1)浓度处理下，甚至使作物种子失去活力；(2)加拿大一枝黄花叶和花序的水浸提液对种子萌发和生长的影响要大于其茎的浸提液；(3)在3种作物中，长梗白菜种子对加拿大一枝黄花水浸提液的敏感性最高。

In this paper, chemistry composition, fiber morphology and pulping property in Solidago canadensis were analyzed and determined preliminarily. The results showed that the content of holocellulose was 81.86%, the content of cellulose was 42.63%, the content of lignin was 18.86%, it is feasible for using Solidago canadensis pulping based on it's chemical composition. The ratio of fiber length to width in Solidago canadensis was 36.67, the average length of fiber was 440 μm, and the length of fiber was too short to pulping. The ratio of wall thickness of fiber cell to lumen diameter was 0.34, and it was smaller than that of other woody fiber. In this experiment, four different methods of pulping were as follows: kraft-AQ pulping Ⅰ, kraft-AQ pulping Ⅱ, alkaline pulping, alkaline sulfite adding AQ pulping, but it was difficult for lignin removal in Solidago canadensis.

通过对一枝黄花的化学组成、纤维形态以及制浆性能进行初步探索，结果表明：(1)加拿大一枝黄花的综纤维素含量为81.86%，硝酸乙醇纤维素含量42.63%，木素含量18.86%，由化学组成看，加拿大一枝黄花是比较适宜制浆造纸的；(2)加拿大一枝黄花纤维的长宽比为36.67，纤维平均长度为44μm，从纤维长度来看，加拿大一枝黄花的纤维较短，不适宜制浆，其纤维壁腔比0.34，和其它速生材相比较小；(3)采用4种碱法制浆方案，硫酸盐蒽醌法Ⅰ，硫酸盐蒽醌法Ⅱ、烧碱法、碱性亚钠＋蒽醌法，结果显示，加拿大一枝黄花的木素非常难脱除。

In three experimented species, the effect of water extract from host plant on Poa annua and Brassia campestris were more significant than Basella rubra.

结果表明：（1）加拿大一枝黄花地上部分的化感作用是存在的；（2）高浓度的加拿大一枝黄花水浸提液对3种植物种子的萌发特性（终萌发率、发芽速率和发芽动态）均有明显的抑制作用，其中Poa annua和Brassia campestris受到的影响比Basella rubra较为明显。

ResultsESC(the extract of Solidago canadensis L.) markedly prolonged the writhing latent period and decreased the times of writhing of mice induced by ip acetic acid, while it had no obvious effect on the pain threshold value in hot plate test. ESC significantly prolonged the tussive latent period of mice, decreased the tussive times and increased phenolsulfonphthalein excretion quantity of trachea of mice. ESC was nontoxic according to the acute toxicity test.

结果首次对国产加拿大一枝黄花进行了体内药理作用研究，发现加拿大一枝黄花提取物能显著延长醋酸致小鼠扭体潜伏期，减少扭体次数；但未明显提高热板法实验小鼠的痛阈值；能显著抑制浓氨水所致小鼠咳嗽潜伏期和咳嗽次数；显著增加小鼠气管的酚红排泌量；急性毒性实验表明加拿大一枝黄花提取物无明显毒性，既不引起小鼠死亡也不影响小鼠体重正常增加。

Results Both of the propellant rates (P＜0.01) of charcoal powder in the small intestines of the mice were raised remarkably and the constriction (P＜0.01) of the ileum smooth muscle of the rat was greatly strengthened by Goldenrod Herb.

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
