And so tree peony is the main economic support of the product area of tree peony .All of this need a systemic and scientific cognition of the rules of grow and development of tree peony. But as the study on the physiological and biochemical changes during the period of forming strong buds of tree peony is concerned, the level is very low and still use the traditional methods of cultivation and management . So if we want to get the quality flowers ,we should have quality buds and we should use all methods ,if we can , to meet the conditions that tree peony needs. And so it is very important for theory and practice to study the physiological and biochemical changes during the period of forming strong buds of tree peony.
但是,不论是生产商品苗木还是用于反季节催花,都需要对牡丹的生长发育规律有一个系统和科学的认识,然而,目前的牡丹栽培仍然衍用传统的栽培技术,对牡丹生长发育过程中的生理生化变化规律的认识,却还停留在比较肤浅的水平和层次上,因此要得到高质量的牡丹花,就要有高质量的牡丹芽,就必须按照牡丹的生长发育规律,建立科学的栽培技术体系,在牡丹壮芽形成过程中运用一切可以运用的栽培措施、管理技术来满足条件,因此,对牡丹壮芽形成过程中的生理生化变化的研究就具有十分重要的理论和实践意义。

This paper made a systematic research on Lonicerafulvotomentosa Hsu et S.C. Cheng, which grows well inkarst areas, from its biological characteristics, such asmorphology, growth and physiology. The main conclusions asfollows:(1)From the viewpoint of morphological anatomy, it hastypical xerophyte structures such as well-developed epidermisand tissues that transport water effectively, small leaf area,dense floss under the leaf surface, high stoma density, thesmall opening degree, thick cuticle, well-developed xylem andpalisade tissues, etc. The pollen of L. fulvotomentosa isseems to be spherical, and has 3 grooves, much bulge on theepidermis evenly. The shape of pollen is an important featureon taxonomy. The ripe fruit has from 1 to 18 seeds, some fruitbranch has 135 berry, its diameter is up to 0.8 centimeter.(2)From the viewpoint of growth, L.

The basin experienced three basin-forming cycles of Neopaleozoic, Mesozoic and Cenozoic Eras. Mesozoic fault and depression compounding basin composed the northern margin Jurassic petroleum system and the Cenozoic large-scale strike-slip and compressional basins composed the Tertiary petroleum system of the western Qaidam basin and Quaternary petroleum system of Sanhu. The intense tectogenesis of Yanshan and Xishan made the Jurassic petroleum system of the northern Qaidam more complex. The monocycle paleoclimate evolution in Cenozoic Era and multi-tectonic movement made the lake-basin evolution, hydrocarbon source-rock, reservoir development, accumulation condition and petroleum distribution are more exceptive in character and complex in feature.
该盆地经历了晚古生代、中生代和新生代3个成盆旋回,中生代断坳复合盆地形成了柴达木盆地北缘侏罗系油气系统,新生代大型走滑挤压盆地形成了柴达木盆地西部第三系油气系统和三湖第四系天然气系统,燕山和喜山2期强烈构造运动使柴北缘侏罗系油气系统高度复杂化,新生代单旋回古气候演化与多期构造运动使湖盆演化、烃源岩和沉积储层发育特征、成藏条件与油气分布规律变得十分特殊和复杂。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称;三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起,称之为挽歌体诗人或者史诗诗人,他们被称为诗人,似乎只是因为遵守格律写作,而非他们作品的模仿本质。
