印度旁遮普邦种植的各种大田作物中,杂草危害已成为大问题。密植系统使所需的农业投入包括肥料、灌溉等更多,杂草引起的损失也逐渐增加。根据作物的种类和杂草的性质不同,谷物产量损失的幅度一般为15～25%,但在草害严重的情况下,谷物甚至会颗粒无收。鉴于杂草引起的损失的程度,采用某些适当的杂草防除技术是非常必要的。采用机械方法或化学方法都可有效地防除这些杂草。
The hazards of weeds have become a big problem among the various field crops grown in Punjab, India. Close planting systems make the required agricultural inputs, including fertilizers, irrigation and more, and the weed-related losses also increase. Depending on the type of crop and the nature of the weeds, cereal yields generally fall between 15% and 25%, but even in the case of serious grazing, the grains are not even collected. Given the extent of the damage caused by weeds, it is imperative to employ some appropriate weed control techniques. These weeds can be effectively controlled by both mechanical and chemical methods.
