摘要
采用5因素5水平正交施转回归设计,对陕西水地棉花高产栽培技术中的密度、肥料、缩节胺等5项主要农艺措施进行了深入研究。结果表明:各因素作用大小依次为密度>缩节胺>尿素>硫酸钾>二铵。研究了各项农艺措施间的交互作用对产量的效应,获得了≥1875kg/hm2最佳农艺措施组合方案,通过反馈示范,提高了棉花产量。
The main agronomic measures, density, fertilizer and DPC, etc and their interactions were researched by the methods of the orthogonal rotary experiment and the regression equations. The result of experiment showed that the effect of five factors on output was in turn density>DPC>CO(N-H2)2>K2SO4>(NH4)2 HPO4, and that the Optimum combination of comprehensive, agronomic measure was obtained, for that yield per hm2 could get to above 1875kg.
