为探讨秦油2号高产低耗栽培技术,应用5元2次正交回归旋转组合设计方法,对秦油2号的播期、移栽叶龄、密度、施肥、病害防治等5项主要栽培措施综合研究,试验结果如下。材料与方法本试验于1990～1991年在天柱县城关坝区进行,试验选用秦油2号的播期,移栽叶龄、密度、施肥及病害防治等5项农艺措施为因 In order to explore the high-yielding and low-consumption cultivation techniques of Qinyou No.2, 5 major and 2-times quadratic regressive rotation combination design method was used to analyze five main cultivars of QinYu No.2 such as sowing date, transplanting leaf age, density, fertilization and disease prevention and control Comprehensive measures, the test results are as follows. MATERIALS AND METHODS The experiment was conducted in Chengguanba District, Tianzhu County from 1990 to 1991. Five agronomic measures such as sowing date of Qin Yu No.2, transplanting leaf age, density, fertilization and disease control were selected as the reason
