| 摘 要： | 为实施西兰花的高产高效栽培,以西兰花"绿雄90"为试材,选择定植苗龄、种植密度、氮肥用量3个主要栽培因子布置田间试验,测定有关参数,建立西兰花生产中的主要栽培因子与生育期和产量的数学模型。结果表明:定植苗龄(x1)、种植密度(x2)、氮肥用量(x3)对其生育期(y1)和产量(y2)影响的数学模型为y1=75.1322+1.6361x1-0.0001x2+0.0014x3(r=0.8888**),y2=14 999.1852+404.0006x1-0.1986x2+3.6196x3(r=0.6058**)。利用模型组创西兰花标准化栽培技术,对开展西兰花生产决策和调控具有良好的指导和参考作用。

| Abstract: | In order to strengthen the competitiveness of broccoli industry,a set of mathematical models between the plantation seedling(x 1),the planting density(x 2),the usage of nitrogenous fertilizer(x 3) and the reproductive stage(y1) and yield(y2) by the comprehensive research on these factors were constructed which regulated the reproductive stage and yield.The results showed that y1 =75.1322+1.6361x 1-0.0001x 2 +0.0014x 3(r=0.8888 **),y2 = 14 999.1852+404.0006x 1-0.1986x 2 +3.6196x 3(r=0.6058 **).The rational use of the mathematical models made an improtant direction and referential value on safe allocation of production and standard cultural techniques in broccoli. |
