马铃薯高淀粉品种I-1085丰产栽培措施研究
Cultivated Technique of I-1085, a Potato Variety with High Starch Content
【摘要】 采用最优回归设计,研究了I-1085块茎产量与种植密度,氮、磷、钾施用量间的关系,建立了4因素与产量关系的数学模型,根据模型拟出该品种产量与密度、氮磷钾施肥水平的最佳方案。
【Abstract】 The mathematics model of the relationship between yield and four factors is established after investigating the relationship between the tuber yield and planting density, applied amounts of nitrogen, phosphorus and potassium by an optimum regression design. The best cultivation scheme including the density and fertilizer levels of nitrogen, phosphorus and potassium is put forward on the basis of the model.
