| 为了明确近年来河南省小麦田主要杂草种类及发生情况, 采用倒置“W”9点取样法对河南省小麦主要种植区16地市麦田杂草发生情况进行了调查。结果表明, 河南省小麦田杂草共有25种, 其中阔叶杂草16种, 禾本科杂草9种。优势杂草有拉拉藤Galium spurium L.、牛繁缕Stellaria aquatica (L.) Scop.、播娘蒿Descurainia sophia (L.) Webb ex Prantl、荠Capsella bursa-pastoris (L.) Medik.、阿拉伯婆婆纳Veronica persica Poir.、宝盖草Lamium amplexicaule L.、节节麦Aegilops tauschii Coss.和多花黑麦草Lolium multiflorum Lamk.。其中, 拉拉藤在我省的发生分布范围最广, 频度达44.91%; 而多花黑麦草成为新的麦田优势禾本科杂草, 已在我省7个地市发生危害。我省不同地区小麦田杂草发生种类存在较大差异, 信阳地区以日本看麦娘Alopecurus japonicus Steud.、看麦娘A.aequalis Sobol.为主, 且发生密度最高, 达9.72株/m2; 而南阳地区草相最丰富, 达18种; 安阳地区杂草种类最少, 仅有7种。我省不同地区杂草发生情况差异较大, 建议加强杂草优势种发生分布监测, 建立针对性的区域杂草防除技术体系。 |

| To elucidate the species composition and prevalence of weeds in wheat fields in Henan province in recent years, a survey was undertaken to examine the occurrence of weeds in wheat fields across 16 cities by the inverted “W” nine-point sampling method. The findings reveal that there are 25 distinct species of weeds present in wheat fields, comprising 16 species of broad-leaf weeds and nine species of grass weeds. The predominant weed species identified include Galium spurium L., Stellaria aquatica (L.) Scop., Descurainia sophia (L.) Webb ex Prantl, Capsella bursa-pastoris (L.) Medik., Veronica persica Poir., Lamium amplexicaule L., Aegilops tauschii Coss., and Lolium multiflorum Lamk. The prevalence and distribution of G.spurium is notably extensive, exhibiting a frequentness of 44.91%. Concurrently, L.multiflorum has emerged as a new dominant grass weed in wheat fields, 〖JP3〗inflicting damage across seven cities in Henan. There are variations in weed species composition across different regions. In Xinyang, the predominant weeds are Alopecurus japonicus Steud. and A.aequalis Sobol., with a notably high density of 9.72 plants/m2. In contract, Nanyang has the greatest diversity of grass species, encompassing 18 distinct varieties, while Anyang is characterized by the fewest weed species, totaling only seven. The occurrence of weeds exhibits considerable regional variability, accompanied by a succession of weed communities. It is advisable to enhance the monitoring of dominant weed species distribution and to develop targeted weed management strategies. |
