动物对植物的取食,即植食过程,是自然界最为常见的生物间相互作用之一。这一过程对植物的生长、繁殖、生存以及生物多样性维持有着深远影响。然而,自然界中的植食程度在不同物种之间差异巨大,如何解释这种差异,已成为当前群落生态学领域数十年来关注的基本科学问题之一。

Weed Ecology and Nonchemical Management under Strip-Tillage: Implications for Northern U.S. Vegetable Cropping Systems
Tillage vegetable crops weed control
2015/12/23
In northern U.S. vegetable cropping systems, attempts at no-till (NT) production have generally failed because of poor crop
establishment and delayed crop maturity. Strip tillage (ST) minimizes these...
