不同水热调控方式对苹果—大豆间作系统土壤温度和根系分布的影响
Shuitu Baochi Xuebao, 2023 为探究适于黄土区果农间作系统的水热调控方式,选取该区典型的苹果—大豆间作系统为对象,分析不同水热调控方式对间作系统耗水量、土壤温度及根系分布的影响。试验设置3个灌水量上限:田间持水量的50%(W1),65%(W2)和80%(W3);2个覆膜时间:大豆播种至结荚期(M1)和全生育期覆膜(M2)。结果表明:灌水处理的耗水量与灌水量呈正相关,其耗水量较对照提高1.02%~79.11%。土壤温度在分枝和结荚期随土层深度的增加先增后减,最大值出现在15 cm,而在鼓粒期却呈减小趋势。覆膜在生长前期可增温1.13 ...

Exploring the importance of aromatic plants' extrafloral volatiles for pollinator attraction
New Phytologist, Volume 248, Issue 2, Page 517-528, October 2025.Summary Aromatic plants occur in many plant lineages and have widespread ethnobiological significance. Yet, the ecological significance and evolutionary origins of aromatic volatile emissions remain uncertain. Aromatic emissions have been implicated in defensive interactions but may also have other important functions.
