【摘要】 野花组合是符合"生态园林、低碳发展"理念的城市园林造景手法。以花卉为主,设计3因素、3水平正交试验L9(34),探究植物种类组成(A)、生活型比例(B)、播种量(C)3种处理因素对野生花卉组合建植初期花卉密度及杂草密度的影响。结果表明:各因子对花卉密度的重要性依次为C、A、B,其中因素A、C在发芽后的第21天对组合花卉密度的影响差异显著(α=0.05);发芽期各因子对杂草密度控制效果的重要值R依次为7 025(B)、5 425(A)、1 775(C),其中因素B对发芽后14d杂草密度的影响差异显著(α=0.05)。更多还原

【Abstract】 Wildflower meadow is a method with philosophy of ecological-based gardening,low-carbon development in establishing urban landscape.The effect of plant species combination(factor A),growth form percentage(factor B),sowing quantity(factor C)on flower and weed density were studied by orthogonal experiment design included 3factors and 3levels.The results showed that the importance of 3factors to average flower density was factor C,factor A,and factor B from high to low,successively,of which the average flower density was affectedsignificantly by factor A and C atα=0.05level on the 21st day after germination.The importance value of 3factors to weed density control was 7 025(factor B),5 425(factor A),and 1 775(factor C)from high to low,successively,of which the effect of factor B on weed density atα=0.05level on 14th day after germination.更多还原
