随着旱田作物栽培的不断发展,大豆的栽培面积也不断增大。在2002年,世界大豆的耕种面积为 8120万hm2,到2003年则为8520万hm2,增加了 4．7％。产量的增长,无疑也加剧了市场竞争,故而在大豆栽培中更加强调省力、低成本及高品质,以能在剧烈的市场中立于不败之地。要提高大豆品质, 对大豆田的杂草管理也是至关重要的一个环节。本文就国外大豆田的主要杂草及其防除对策作一概述。
With the continuous development of dryland crop cultivation, soybean cultivation area is also increasing. In 2002, the world soybean cultivated area was 81.2 million hm2, while in 2003 it was 85.2 million hm2, an increase of 4.7%. The increase in output undoubtedly exacerbated the market competition. Therefore, more emphasis on labor-saving, low-cost and high-quality soybeans was cultivated so that they could be invincible in the fierce market. To improve the quality of soybeans, weed management in soybean fields is also a crucial link. This article gives an overview of the main weeds in foreign soybean fields and their control measures.
