摘要： [目的]通过喷施肥料效应田间试验,检验雌花盛花期喷施硼酸(B)、尿素(N)、糖(S)复合肥料对盛果期新温185号核桃坐果率的影响,为新疆南疆盆地新温185号核桃根外肥料的科学有效施用提供解决方案.[方法]采用“3414”喷施肥料效应田间试验和多元线性逐步回归分析.[结果]新温185号核桃坐果率的常用对数(log10q)与硼酸(B)、尿素(N)的喷施浓度及二者的交互作用(B×N)存在极显著的线性相关关系(P＜0.01),且与硼酸、尿素的喷施浓度呈极显著正相关,与二者的交互作用(B×N)呈极显著负相关,即:log10q=1.641 0 +0.066 9B +0.047 3N-0.012 8B ×N.糖(S)的喷施浓度与新温185号核桃坐果率常用对数的相关性不显著(P＞0.05).新温185号核桃雌花盛花期硼酸(含硼17.49;)的适宜喷施浓度为3.695 3g/L,尿素(含氮46;)的适宜喷施浓度为5.226 6 g/L,理论坐果率期望值可达到77.31;.[结论]雌花盛花期喷施硼酸和尿素的复合肥料,可显著提高新疆南疆盆地盛果期新温185号核桃的坐果率.
