侧柏

The species that blooms in lent is "Helleborus Orientalis."

这种&铁筷子侧柏&在四旬斋期开花。

The characteristics of the resaturated absorbing water of Platycladus orientalis, Juniperus rigida, Hippophae rhamnoides, Populus adenopoda under the different deficit in Huhhot were studied.

以生长在呼和浩特地区的侧柏、杜松、沙棘、新疆杨为对象，研究其小枝在不同水分亏缺状态下恢复吸水能力，结果表明：(1)小枝重饱和初始水分亏缺程度越大，重饱和相对饱和含水量越小，失水后水分恢复能力也越低，树木组织受到的伤害越严重。

Compared with the control,the relative contents of 3-Carene and thujopsene increased significantly and that ofα-Pinene、β-phellandrene、β-Pinene and Limonene decreased in weak trees.

但是衰弱侧柏中3-蒈烯和罗汉柏烯含量明显升高，α-蒎烯、β-蒎烯、β-水芹烯和柠檬烯含量减低。

Parviflora in shrub communities had the xeromorphic traits in the aspects of ① their secondary xylem had shorter vessel elements, higher vessel frequency, less single porous percentage, lower rays, higher relative conductivity and lower vulnerability index, and ② their leaf had lower water potential, lower water content and free water content, higher bound water content, high ratio of bound to free water content, and less specific leaf area.

扁担木叶片、次生木质部的解剖和水分生理特征均表现出一定的可塑性，其可塑性指数高低顺序为次生木质部解剖特征（0、24）〉水分生理特征（0.19）〉叶片解剖特征（0.18）、与侧柏林和混交林相比，灌丛中扁担木个体对干旱生境有一定的适应能力，表现在次生木质部导管分子短，导管频率高，单孔率低，木纤维短，射线矮小，具有较大的相对输导率和较小的脆性指数；叶片水势、组织含水量、自由水含量较低，叶面积、比叶面积较小，而束缚水含量、束缚水自由水比值较高。

Cacumen Platycladi: its broken up, plus the same amount of water rub, squeeze liquid, plus 2 times the water spray can control cotton aphid and stem borers.

侧柏叶：将其捣碎，加等量的水揉搓，榨出原液，再加水2倍喷洒，可防治棉蚜和螟虫。

In inche overlaps, the niche overlop of B. platyphylla and P. davidiana, B. platyphylla and A. mono, B. platyphylla and J. mandshurica were big. Otherwise, P. orientalis, Q. aliena, Ailanthus altissima, U. macrocarpa with other species were small.

3在生态位重叠指数中，白桦和山杨、色木槭和白桦、白蜡和胡桃楸、色木槭和山杨生态位重叠较大，而侧柏、槲栎、臭椿和大果榆与其他的多个主要树种的生态重叠指数较小。

In the aspect of niche, the niche breath of B. platyphylla, Quercus aliena, Fraxinus spp., B. dahurica were big, but A. mono, Ulmus macrocarpa, Armeniaca sibirica, Platycladus orientalis were small.

2在生态位方面，白桦、槲栎、白蜡、黑桦的生态位宽度较大，而色木槭、大果榆、山杏、侧柏的生态位宽度较小。

Photosynthetic rate P(subscript n, transpiration rate, stomata conductance G(subscript s, active photosynthetic radiation, relative air humidity, air temperature and water use efficiency of three tree species Platycladus orientalis, Pinus tabulae formis, Tamarix chinensis were measured with a portable LI-6200 gas analysis system under natural conditions in the mountains adjacent to Lanzhou City.

利用LI-6200便携式光合测定仪对兰州市南北两山侧柏、油松、柽柳等3种绿化树种在自然条件下的光合速率P(下标 n、蒸腾速率、气孔导度G(下标 s、光合有效辐射、空气相对湿度、大气温度和水分利用效率进行了测定。

The correlation analysis and stepwise regression between physiological characteristics of three species and environmental factors showed that the regression equation of Platycladus orientalis between photosynthetic rate, transpiration rate and the environment factor was P(subscript n=0.006PAR+1.176RH, E=1.120T; the regression equation of Pinus tabulae formis was P(subscript n=0.010PAR, E=1.004T+0.482RH; the regression equation of Tamarix chinensis was P(subscript n=0.015PAR, E=0.757T+0.566RH-8.397G.

对3种树的光合速率和蒸腾速率与影响因子进行相关分析及逐步回归分析表明，各树种光合速率和蒸腾速率的回归方程分别为，侧柏：P=0.006PAR+1.176RH，E=1.120T；油松：P=0.010PAR，E=1.004T+0.482RH；柽柳：P=0.015PAR，E=0.757T+0.566RH-8.397G。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
