优化水肥与滴头间距组合对日光温室黄瓜生长及产量的影响
S626%S27; 为探究水肥耦合+滴头间距对宁夏旱区日光温室春夏茬黄瓜生长、产量、品质和水肥利用率的影响.通过3因素3水平正交试验,利用Logistic方程模拟黄瓜株高变化规律,分析了各时期生长特点;利用极差分析和方差分析,研究了水肥耦合+滴头间距影响主次顺序、显著性及变化趋势,同时结合模糊数学隶属函数法对产量和品质指标进行综合评价,筛选最优组合.结果表明:①不同处理下黄瓜株高"S"形生长过程可分为渐增期、速生期、缓增期3个阶段,可用Logistic方程拟合,且相关系数均高达0.97;②春夏茬日光温室黄瓜在采摘期前3个月产量稳定,分别占总产30.19％、29.22％、28...
