作物干扰控制杂草的前景

Prospects for weed control through crop interference.

杂草作为农田生态系统中的负效应组分,长期困扰农业生产活动。作物干扰,即作物对邻近杂草生长和繁殖的抑制作用,是基本的非化学除草方法之一。作物干扰可通过育种和栽培途径来增强,作物干扰能力的增强将伴随着一定的产量代价,但在某些条件下干扰能力强的作物品种有一定的产量优势。

Weed, as a component with negative effects in agroecosystem, has been disturbing human's agricultural production for a long time. Crop interference, defined as the control effects exerted by crop plants to the growth and reproduction of neighbouring weeds, is a fundamental method of nonchemical weed control. The ability of crop interference to weeds could be enhanced by crop breeding and management. The enhancement of crop interference would pay a price in the crop yield. However, in some particular conditions, varieties with strong crop interference have a yield advantage.
