云杉

It is the only alpine long-term ecological research site in Taiwan. Bimonthly insect collection was conducted from November 1998 to March 2002 at the three sampling plots, including spruce forest, hemlock forest and meadow at Tatachia LTER site in the Yushan National Park.

本实验从1998年11月至2002年3月，在塔塔加高山地区长期生态研究(Long Term Ecological Rearch； LTER)研究区进行两个月一次的昆虫定期调查，样区选定在云杉林、铁杉林及箭竹草原等三个永久样区内，调查方法包括日间扫网调查和夜间灯光诱集。

The evergreen plants consists of Chinese pine, hemlock, fir and dragon spruce; the red-leaf plants are maple, little tiller, smoke tree and others; the yellow-leaf plants are birchm, golden-rain tree, elm, larch, poplar mix together in harmony, offering a rainbow of natural pictures that easily please to our eyes, It is commonly believe that the colerful plant scenery is one of the main features manifested in Jiuzhaigou.

这些长青植物由中国松树，毒芹属植物，冷杉和龙云杉组成。红叶植物是枫树，烟树以及其他树种。黄叶植物是白桦，金雨树，榆树，落叶松属植物，融合在一起构成了一幅养眼的天然彩虹图画。普遍认为，植被景色是九寨沟的主要特色之一。

By 20 spruces have the long wood, certainly the good sympathetic chord, the stable size and the good agglutination performance, therefore it is often used for to manufacture the high quality musical instrument sounding board.

由于 云杉具有较长的木纤维、绝佳的共鸣、稳定的尺寸和良好的胶合性能，所以它常被用来制作优质乐器共鸣板。

Jack pine had higher rate of gas exchange and water use efficiency than black spruce when seedlings were well watered.

解除干旱胁迫后，黑云杉的气孔敏感性、光合能力及水分利用效率的恢复都要比北美短叶松更快。轻度的干旱胁迫锻炼可以帮助北美短叶松在更严重的干旱胁迫下保持固有而强劲的耐旱能力。

Effects of repeated cycles of dehydration\|rehydration on gas exchange and water use efficiency were studied in one\|year\|old jack pine Pinus banksiana Lamb.

该文研究了多重复干旱循环对1年生北美短叶松和黑云杉苗木的气体交换速率及水分利用效率的影响。结果表明，多重复干旱循环对它们的气体交换有显著影响（P＜0.5），而对其水分利用效率影响不大（P＞0.1）。

Diurnal gas exchange for aspen, jack pine and black spruce indicated afternoon depression. In hazelnut, a second peak in Pn occurred in the afternoon.

欧洲杨、短叶松和黑云杉的日气体交换率均表现午后抑制，榛子在下午出现了第二个Pn高峰。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
