| 摘 要： | 2008-2009年通过利用当地常见的10种杂草种植于不同处理的农田,研究半干早区农田杂草群落结构以及10种杂草群落组分种对环境因子的响应,结果表明,1)同一物种在不同的气候环境下,可以表现出不同的生活史策略.蝇虫实、田旋花和金荞麦2008年生活史策略分别具有竟争型(C)对策属性、胁迫忍耐型(S)对策属性和中间型(C-...

| Abstract: | From 2008 to 2009,the response to environmental factors of the weed community structure in semiarid cropland was researched by selecting 10 native weeds and planting them in differentially treated cropland.1) The same species in different climates showed different life-history strategies: Corispermum,Convolvulus arvensis,and Fagopyrum dibotrys tended towards the competitor(C) strategy,stress tolerant(S) strategy,and mixed competitor-stress tolerant(C-S) strategy in 2008,but towards the stress tolerant(S) st... |
