湘油11号是一个新育成的双低油菜品种,现已在湖南省大面积推广。为了探讨该品种的高产栽培措施,我们运用农业系统工程学原理和方法,研究了该品种播期、密度、氮、磷、钾用量五种主要栽培措施与产量之间的关系及其数学模型,并利用计算机模拟寻找优化方案,力图摸清各主要栽培因子的相互关系,为高产栽培提供科学依据。 Xiang You 11 is a new breed of double-low rapeseed varieties, is now a large area in Hunan Province to promote. In order to explore the high-yielding cultivation methods of this variety, we used the principles and methods of agricultural systems engineering to study the relationship between sowing date, density, nitrogen, phosphorus and potassium dosage and its yield and its mathematic model, And use computer simulation to find optimization programs, trying to find out the relationship between the major cultivation factors, to provide a scientific basis for high-yielding cultivation.
