| 摘 要： | 灰灰菜与藜麦形态和生长特性相似,是藜麦田中的顽固杂草,难以防除。为了探究不同栽培密度下藜麦对同科杂草灰灰菜的抑制效果,本研究设置高(67株/m2)、低(10株/m2)2种藜麦栽培密度,比较2种密度下藜麦在3种生长条件(自生组、间生组和替生组)下灰灰菜的农艺性状差异。结果表明:藜麦高密度栽培较低密度栽培在不同生长条件下对于抑制同科杂草灰灰菜均具有显著差异;同一藜麦栽培密度下,灰灰菜居间生长所受到的抑制效应较大。

| Abstract: | With similarities to quinoa in morphology and growth characteristics, Chenopdium album L. is a stubborn weed in quinoa field and difficult to control. In order to study the inhibitive effects of quinoa at different planting densities on the growth of Chenopdium album L., quinoa was planted at the two densities 40 cm×25 cm and 20 cm×7.5 cm. Chenopdium album L. was grown under three growth conditions: free growth, replacing growth, and intercalary growth. The agronomic characteristics of Chenopdium album L. were compared under different quinoa planting densities and different growth conditions. The results indicated that increasing quinoa planting density markedly suppressed the growth of Chenopdium album L. under the different growth conditions. Under the same planting density, intercalary growth had strongest inhibitive effects on the growth of Chenopdium album L.. |
