以工业发展为背景,对室内绿色植物陈设艺术的发展进行初步探索。在盆栽出现以前室内绿色植物就已经出现,室内绿色植物陈设的起源与盆栽相关。室内绿色植物陈设艺术在4000年前萌芽,其现代意义上的发展取决于工业革命带来的材料与结构的发展,尤以钢和玻璃最为重要。英帝国海外殖民时期,大量海外植物的引进将室内绿色植物陈设艺术推向高潮。20世纪60年代,共享中庭的兴起带动了景观主题室内大空间发展,20世纪80年代,绿色建筑实践给室内绿色植物陈设带来了新的思路。 相似文献

在我国,城镇居民的生存环境中绿色植物的种植区域非常有限而且可以种植的土地质量太差,当今社会对绿色景观的文化要求越来越高,对于绿色植物的功能、感官、实惠、生活要求愈来愈有品位,对种植何种花草和各种植物的搭配非常关键。这篇文章就是对各种果木类的景观进行了较为详细的研究。 相似文献

自然界中的颜色通常都是和进化过程有关系的.我们能看到的绿色植物颜色的色素沉淀也不例外,一定是进化过程的产物. 相似文献

制浆造纸厂固废绿泥,目前尚无很好的综合利用方法,普遍都是填埋、焚烧。各厂因制浆工艺、原料以及碱炉工况的差异,造成绿液固体悬浮物差异很大,故绿泥产生量相差几倍甚至几十倍。本文简要分析了国内化机浆黑液碱回收绿泥产生的原因、绿泥资源化处理方法及绿泥减量化的工艺措施。 相似文献

减施肥料对不同前茬烤烟生长和产质量的影响 总被引:1,自引:0,他引:1
为提高养分资源利用效率、保护生态环境和增加经济效益,通过田间试验研究了油菜、冬闲、绿肥、大麦、小麦5种前茬烤烟在当地常规施肥基础上分别减施氮肥(对绿肥茬、冬闲茬和油菜茬烤烟)和钾肥(对小麦茬和大麦茬烤烟)对烟株生长、烟叶产量和质量的影响。结果表明,油菜茬、绿肥茬、大麦茬和小麦茬烤烟减施肥料处理不仅不影响烤烟正常生长发育和落黄成熟,而且移栽后不同生育期生物量均有所增加,烤后烟叶产质量、烟叶化学成分协调性也皆以减施肥料处理较好。而冬闲茬烤烟减施肥料处理烟株前期营养生长较弱,后期营养生长较强,烤后烟叶产质量降低,烟叶化学成分协调性和烟叶品质也较差。综合而言,在当地常规施肥的基础上,绿肥茬和油菜茬烤烟可以分别减施氮肥25%和9%,大麦茬和小麦茬烤烟均可以减施钾肥10%,但冬闲茬烤烟不宜减施17%的氮肥用量,适宜施肥量有待于进一步研究。 相似文献

The quantities of protein which can be extracted from green plants depend on a number of factors such as the botanical composition of the plant, its growth stage, topdressing and system of extraction. Leaf protein concentrates have been incorporated into food for human consumption, but their green color has limited its application. Thermal precipitation of chloroplastic material is not specific, causes denaturation and requires high energy input. A selective recovery of the green fraction is possible by centrifugation at high centrifugal forces or by the combination of this method with an addition of calcium salt to a green juice. Application of high molecular polyelectrolytes in green juice precipitation allows the separation of pigmented material at room temperature. The objective of this work was to determine the effect of cationic and anionic flocculants on fractionation of alfalfa green juice into two fractions: chloroplastic (green LPC) and cytoplasmatic (white LPC). 相似文献

The quantities of protein which can be extracted from green plants depend on a number of factors such as the botanical composition of the plant, its growth stage, topdressing and system of extraction [1, 7, 8]. Leaf protein concentrates have been incorporated into food for human consumption, but their green color has limited its application [6, 9]. Thermal precipitation of chloroplastic material is not specific, causes denaturation and requires high energy input [9]. A selective recovery of the green fraction is possible by centrifugation at high centrifugal forces or by the combination of this method with an addition of calcium salt to a green juice [3, 4]. Application of high molecular polyelectrolytes in green juice precipitation allows the separation of pigmented material at room temperature [2, 5]. The objective of this work was to determine the effect of cationic and anionic flocculants on fractionation of alfalfa green juice into two fractions: chloroplastic (green LPC) and cytoplasmatic (white LPC). 相似文献
