<正>随着生态园林的发展,利用植物造景既是园林造景的一个重要方面,又是一个比较复杂的课题。由于季节的变化,植物在树形、色彩、叶丛疏密和颜色等方面也会发生变化,这些变化在园林中可形成丰富的景观效果,给游人在视觉、观赏特性等方面增添游兴。彩叶植物具有色彩鲜艳、成景快、栽培容易、观赏期长的特点,能补充常绿植物的不足,丰富环境色彩,因此成为园林造景植物配置中的重要组成部分。     

Evaluation of nutrient value of seabuckthorn in north China

Five minerals or elements, crude protein, lysine, methionine cystine, calcium and phosphorus, were selected for evaluation of the food value of seabuckthorn (Hippophae rhamnoides ssp. sinensis) using the method of "food analysis". The decision values (δi) of seabuckthorn seeds, leaves and fruit residues rank in the fifth, sixth and ninth position among the 16 types of fodder. Seeds, leaves and fruit residues of seabuckthorn are suitable for livestock and poultry fodder. The weights of livestock and poultry are considerably increased after feeding with seabuckthorn. The development of seabuckthorn should have great potentials as food, pre-food and food additives for livestock and poultry in north China. Processing facilities should pay more attention to seabuckthorn food development methods and strategies and the seabuckthorn fodder industry should be promoted.     

三种园林植物叶形态生理指标及其环境指示作用

The comparative value of wild and domestic plants in home gardens of a South African rural village

Rural inhabitants make considerable use of wild resources from communal areas around their settlements, as well as from arable and residential plots. These wild resources compete with the main crops planted in arable plots and home gardens, but play a significant economic and nutritional role in rural livelihoods. This paper reports upon a conservative financial evaluation of the wild plant resources harvested from home gardens and arable plots by inhabitants of rural village in the Bushbuckridge lowveld (South Africa), and examines their importance relative to other domesticated crops. On average, each household made use of four to five species of wild plants growing on their residential plot, whereas the mean number of crop plants was 3.4. The total value of all plants was R1694 (US$ 269) per household per year, or approximately R4200 (US$ 667) per hectare of home garden per year. Wild plants represented 31% of the value of all plants grown on residential plots, relative to the 69% for domesticated crops (including fruit trees). Approximately 72% of the total value of all plant products was consumed by the household, and the remaining 28% was sold.This revised version was published online in November 2005 with corrections to the Cover Date.     

The structure of four home gardens in the Petén,Guatemala

Forest-covered home gardens around the tropical world vary in their structure, but serve to supply food and other products for direct family consumption or marketing. Little quantitative data exist defining home garden structure. Thus, this study was undertaken to examine the variation in home garden structures in response to market or household needs and the subsequent variation in light interception and productivity.Four home gardens were studied in the Department of the Petén, in northern Guatemala. Areal extent and height of canopies were mapped in transects through four gardens representing a range of site water regimes and market orientation. Light intensities incident on the ground were measured along each transect to assess light use. Results showed structural complexity, with full canopy closure in the one or more layers within the canopy for most gardens. The garden architectures made efficient use of light and space, with intersive management for food and fuel production. Farmers grew the crops for both cash and family subsistence. One home garden on a comparatively dry site with shallow soil seemed less structured, with only a single broken canopy layer, but with diverse species of plants.The results indicate that development of gardens in this area utilized existing trees, thinning them to leave the most useful, and inserting other desirable trees and shrubs in the understory and in open spaces. This strategy seemed to maximize light use, regardless of market orientation.This look at the structure and composition of four home gardens, in a forested area of current immigration, demonstrated (1) variety of organization and plant components, (2) different architecture for different soil/site conditions and market orientations, and (3) efficient use of available light through the arrangement of plants.
