摘要
在互助县高位水地春油菜采用3414平衡施肥试验设计,分析N、P、K营养元素之间的肥料效应,得出肥料效应方程和最佳施肥量。推荐该地区油菜施肥量分别为N:114kg.hm-2,P2O5:60.6kg.hm-2,K2O:18kg.hm-2。此时的最高产量为4185kg.hm-2。
The fertilizer effect on rape was investigated by using the"3414"balance application design to build the mathematical model for the relationship among N, P and K. The optimum fertilization scheme obtained from the model is N: 114kg·hm^-2 ,P2O5:60.6 ·hm^-2, K2O: 18kg ·hm^-2 the yield could reach 4185kg ·hm^-2.
