長葉季節
英文
leaf season-
Thus passed the leafy time when arborescence seems to be the one thing aimed at out of doors
當樹木似乎變成戶外最集中的事物時，樹葉生長的季節就這樣過去了。Accordingly avoided the competition among ramets effectively. their rhizomes developed root system at first. it was easier for roots to live through the winter in the alpine region with short growth season and was propitious to individual plant to survive
黃帚橐吾和箭葉橐吾的分枝角度多呈0 、 180放射狀格局，有效避免了分株間的競爭；同時在生長季節短高寒地區，分株先形成根系，以根系過冬更有利於分株的成活，是適應對策之一。The research object of this paper is the broad - leaved wood of red pine in north slope of changbai mountain. by analyzing the composition, construction, biodiversity and season diversity of forest community, we probed the rule of the forest community changing with the season and the ecological effect of forest insect community affected by forest plant community, appraised firstly regulating ability of forest ecosystem on forest pest and estimated finally effect of forest insect on ecosystem health
本文研究對象為長白山北坡紅松闊葉林帶，通過對森林群落的組成、結構、生物多樣性及其季節變化，探索了森林群落生物多樣性隨季節變化規律，森林昆蟲群落在森林植物群落的影響下的生態效應，對森林生態系統對森林害蟲控制力作初步評價，最後對森林昆蟲對生態系統健康影響作出評價。Branches and leaves dry weights / roots dry weights is higher in cyclobalanopsis multinervis and michelia foveolta under shading, which revealed that growth of roots were restrained by shading. from june to october, special leaf weights, . chla / chlb and soluble sugar contents were decreased in cyclobalanopsis multinervis and michelia foveolta under shading, but leaf w
在6月至10月的整個生長季節，遮蔭處理使多脈青岡和金葉含笑的比葉重下降，葉片含水量上升，葉綠素含量上升， chla / chlb下降，類胡蘿卜素含量上升，可溶性蛋白含量上升，可溶性糖含量下降3. growth and seasonal variation of physiological characteristics of cyclobalanopsis multinervis and michelia foveolta under different shadings. plant height and perimeter of cyclobalanopsis multinervis were decreased in level of extreme significance, which resulted in decreacing branches and leaves dry weights, roots dry weights, the whole dry weighys of plant under shading
3 、不同遮蔭處理下多脈青岡和金葉含笑的生長和生理特性的季節變化遮蔭處理極顯著地降低了多脈青岡的株高和徑粗的增長，因此導致了枝葉干重、根干重及整株干重在遮蔭處理下的極顯著下降。So far new variety is deficient and difficult to popularize because it is hard to know the eclolgical adaptability of plants, so we ca n ' t adjust measures to local conditions. in this paper, we systematically studied photosynthetic characteristics, light response characteristics, photosynthetic diurnal variation, growth, biomass, seasonal variation of physiological characteristics and leaf anatomy of cydobalanopsis multinervis and michelia foveolta under different shadings ( full light, one layer shading, two layers shading ) by ecophysiologi cal methods
本研究運用生理生態學的研究方法，選取目前在園林上應用較少的多脈青岡和金葉含笑的幼苗為研究材料，對其在不同遮蔭處理下（全光照、一層遮蔭、兩層遮蔭）的光合特性、光響應特性、光合日變化、生長情況、生物量、生理特性的季節變化及葉片形態解剖結構等方面進行了較為全面系統的研究。Now the construction work is complete ; the flame tree continues to flourish unaffected. a deciduous tree, the flame tree is affected by the changing seasons and remains dormant when the temperature drops below its ideal growing temperature range of 23 - 30 c
由於鳳凰木為落葉喬木，會受季節周期影響，其生長的最理想溫度為攝氏23 - 30度，現時香港氣溫一般低於攝氏20度，正是鳳凰木的休眠期。分享友人
