摘要
采用播期(A)、穴粒数(B)、穴距(C)、纯氮量(D)四因素三水平的正交试验设计,研究抗黄1号的高产配套栽培技术,试验结果表明,各因素的产量效应排序为C>A>B>D,穴距和播期是影响抗黄1号产量的关键因子,其次是穴粒数,影响最小的是纯氮量。最优处理组合为A3B3C1D1,同时,还就各因素对产量结构、植株性状、生育进程等生理特性的影响作了简要分析。
In order to research high yield cultivation for the new peanut variety Kanghuang 1, in this experiment, four factors： sowing date （A）, seed number per hole （B）, hole distance （C）, nitrogen fertilized （D） were selected for orthogonal yield experiment. The result showed that the importance sequence of factors was： C〉A〉B〉D, hole distance and sowing date were the key factors. And we found the best planting treatment was A3B3C2D1, with average plot yield of 4. 923 kg, Furthermore, based on the K value and its analysis, we draw out the best treatment was A3B3C1D1. At the same time, yield composition, agronomic characters, growth and development, were analysised in this paper.
