摘要

由於農業政策的推廣及農企業的推動，小麥栽培面積在近年來逐漸地增加，為期促進小麥生產量的提升，包括雜草管理在內的相關研究殊有必要加強。臺灣現行小麥的栽植方式，多在水稻收穫後播種，一如南亞地區的稻麥輪作系統。此系統同時存在稻田及麥田的雜草，需要搭配不同的雜草管理方式。本文將介紹稻麥輪作系統下的雜草種類消長與密度分布，並以南亞地區稻麥輪作系統造成雜草相的改變及其控制做法為例，提供臺灣發展在地雜草管理之參考。

Because of the promotion of current agricultural policy and farm enterprises, the culture of wheat has increased steadily in Taiwan in the past years. To further help local wheat production, more research on this grain crop is necessary including weed management. Normally wheat is grown after the harvest of rice, similar to the rice-wheat cropping system in South Asia. The common and dominant weeds occur in rice paddy and wheat field are quite different and therefore, it needs to develop a customized strategy for weed management. We will introduce changes in weed population and density in the rotation of rice and wheat and the practices used to control weeds in the rice-wheat cropping system of South Asia. Such information is required for establishing domestic weed management in rice-wheat based rotation system.
