Abstract
For seeking the cultivating technique with high-yield of rape hybrid Qingza 5 quadratic regression combination design was used to study quantity relation between yield and main cultivating technique (the density and the appolication rate of N, P) also mathematical model of the main factors and yield was established. And then the model made clear that the suitable cultivating technique norm of the excellent combination for the high-yield(more than 5 000 kg/hm2)were density 1.95×105~2.25×105 plants/hm2, the appolication rate of N 146.3~202.5 kg/hm2, P 281.3~337.5 kg/hm2.关键词
