摘  要:
通过调查豫北地区不同轮作制度下农田的杂草种类、数量、分布、相对多度和重要值,分析不同轮作方式对田间杂草群落多样性指数和相似性指数的影响。结果表明,各轮作制度中,杂草数量以小麦-水稻最多,其次是小麦-花生、小麦-大豆、小麦-玉米;相对多度和重要值与田间杂草的优势地位有一致性;小麦-水稻轮作和小麦-花生轮作田间杂草的危害性较大;小麦-玉米轮作和小麦-大豆轮作对杂草的种类和数量有一定的控制作用。

摘  要:
Through investigating weeds in different rotation fields of northern Henan province, weed species, quantity, distribution, relative abundance and important value was used to analyze effects of different rotation systems on diversity index and similarity index in farmland weed community. The results showed that the number of weeds in rice-wheat rotation field was the highest, followed by peanut-wheat rotation, soybean-wheat rotation, maize-wheat rotation. Relative abundance and importance value were coincident in the reaction of weed's dominance. The harm of weeds was great in rice-wheat rotation field and peanut-wheat rotation field weed. Maize-wheat rotation and soybean-wheat rotation had certain control ling effects on types and quantity of weeds.
