查询词典 Solidago

A few epidermal hairs distributed on the Costa of Lonicera Japonica Thumb. The upper epidermis of Solidago decurrens Lour were covered with sparse stellate hairs. The stomas distributed on the upper epidermis hairs of Lonicera Japonica Thunb, Lonicera confuse and Solidago decurrens Lour, which could reflect the sunlight and decrease the transpiration to adapt the highlight and drought environment;(2) The leaf blades of Polygala japonica butt were fleshy, and the sunk stomas distributed on both the sunk place of the upper epidermis and lower epidermis, which help to water conservation.

结果：(1)忍冬、华南忍冬、黄花草下表皮均分布浓密的表皮毛，忍冬上表面中脉有少量表皮毛，黄花草上表皮分布有稀疏的星状表皮毛，忍冬、华南忍冬和黄花草的气孔位于下表皮毛间隙，这种结构可反射阳光和阻止水分蒸发，从而适应强光和水分不足的环境；(2)瓜子金叶片为肉质叶，上下表面均有气孔分布，并出现明显的下陷。

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。

Solidago Canadensis L.1. The risk analysis was abided by the pest risk analysis criterion which was formulated by FAO and IPPC in order to establish the judgement index system of risk quantitative analysis on Solidago Canadensis L.

本文遵照联合国粮农组织国际植物保护公约的有害生物风险分析准则，构建了加拿大一枝黄花风险分析评估量化分析评判指标体系，并确定了各指标的评判标准和等级。

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.
