摘要
以单头切花白菊"神马"为试材,研究了日光温室栽培条件下80、100、120株/m2不同种植密度对白菊生长状况、形态指标和产量的影响。结果表明:在该试验所制定的种植密度范围内,随着种植密度的增加,总产花量增加,单头菊株高和叶片数变化不大,但茎粗、花头直径、花枝鲜重、优花率明显降低。因此存在产量与质量的平衡点,结合此种植茬口效益分析,以100株/m2的综合经济效益最佳,该试验可为实际种植提供参考。
Taking single flower cutting chrysanthemum ‘ White ’(Chrysanthemum morifolium cv.Shenma) as test material,the cultivation density of 80,100,120plants / m 2 greenhouse cultivation conditions on chrysanthemum growth,morphogenesis index and yield were studied.The results showed that within the ranges of test planting density on the greenhouse condition,no effect of the plant height and leaf number was observed,while the stem diameter,flower diameter,fresh mass,and class A product rate decreased significantly as the planting density increasing.Therefore,there was an equilibrium point of productivity and quality.Combined with the benefit analysis,the density 100plants / m 2 had the best economic efficiency.This study could provide a reference for the white cutting chrysanthemum production.
