摘 要: | 本文系统调查了海南剑麻主要种植区的杂草种类,确定了剑麻园的杂草优势种群,并以此为基础进行了剑麻园除草试验。结果表明,本区剑麻园杂草发生种类共有21科121种,其中优势种杂草主要为红毛草、大黍、白茅、短颖马唐、飞机草、假臭草、羽芒菊和含羞草8种杂草;采用间种豆科植物或多年生藤本植物覆盖控草可在一定程度上控制杂草的发生,其中间种花生、大翼豆处理具有明显的防除效果,且间种豆科植物能提高土壤肥力,可以在该地区进一步推广应用。

Abstract: | A systematical investigation of weeds was taken in sisal plantation in Hainan province, and the dominant weed groups were determined. Then, weed control experiments were conducted. The results showed that there were 121 weed species belonging to 21 families in the plantation. Among them, eight species were considered as dominant weeds, including Melinis repens, Panicum maximum, Imperata cylindrica, Digitaria setigera, Chromolaena odorata, Praxelis clematidea, Tridax procumbens and Mimosa pudica. Leguminous crops as intercrops, perennial vines as covering plants could control the weeds to some extent. Arachis hypogaea and Macroptilium atropurpureum as intercrops could have evident effect on controlling the weeds, and leguminous plants could increase the soil fertility. Therefore, their application could be further extended in this area. |
