摘  要:
通过对散枝猪毛菜(Salsola brachiata)、紫翅猪毛菜(S.affinis)、角果藜(Ceratocarpus arenarius)和叉毛蓬(Petrosimonia sibirica)这4种一年生藜科植物幼苗阶段的地上、地下生物量及株高与根长的动态变化进行研究,分析了荒漠植物的生态适应策略。结果表明,4种植物幼苗阶段的植株高度与根均生长缓慢,且根的增长量高于株高的增长量;地上生物量的积累大于地下生物量。4种藜科植物在幼苗阶段所表现出的地上、地下生长策略保证了其幼苗能够在荒漠环境中顺利生长,是植物长期适应荒漠环境所形成的生长策略。

摘  要:
This research was carried out to analyze the ecological adaptability of desolated plants,based on studying dynamic changes of growth quantity,plant height,root length of aboveground and underground of 4 annual chenopodiaceae plants:Salsola brachiata,S.affinis,Ceratocarpus arenarius and Petrosimonia sibirica during the seedling period.The result indicated that the plant height and length of the four plants during seedling period grew slowly and growth rate of root was higher than that of plant height.The strategies performed by seedlings of 4 annual chenopodiaceae plants growing on the aboveground and in underground ensured successful growth of the seedlings in desert environment,whose characteristics were developed in desert environment during long period growth.
