摘要
稻田生态系统是一种需要人工干预的开放系统,其多样性较低,营养结构简单,空白生态位较多,本身具有一定的脆弱性,加之近年来耕作方式的转变,农药化肥的不合理使用等,使其脆弱性增加,更容易受到害虫的攻击。褐飞虱作为水稻主要害虫之一,在对其进行防治时要充分发挥稻田生态系统内各物种间的调节作用,可持续地抑制其暴发危害。本文结合我们以及广东的工作实践,综述了以降低稻田生态系统脆弱性为主旨的褐飞虱综防措施,包括丰产控害栽培防治、高效低毒的化学药剂防治、物理防治、生物防治以及饱和生态位调控防治。
Paddy agriculture ecosystem is an open system with intensive human intervention and low biodiversity index,simple tropic structure and too much blank ecological niches.In passing years,the vulnerability of paddy agriculture ecosystem is enhanced by cultivation mode change,unreasonable use of agricultural chemicals and fertilizers,which make paddy rice more likely to be attacked by agricultural insects.Nilaparvata lugens（Stl）,one of the most destructive rice insect pests,could be sustainably controlled through integrated control including the regulation effects of species.This paper reviews the integrated management of rice brown hopper aimed at reducing vulnerability of paddy agriculture ecosystem,including agricultural cultivation control,high-efficiency and low-toxin agricultural chemicals control,biological control,physical control and ecological niche regulation control.
