| 摘 要： | 以花椰菜“厦雪100天”品种为试材,采用通用旋转组合设计,通过田间试验,对氮、磷、钾肥用量与花椰菜产量间的关系进行研究,建立了花椰菜产量函数模型;结果表明:氮、磷、钾肥均能显著地影响花椰菜产量,其作用大小依次为氮肥>钾肥>磷肥;在此项试验条件下,施肥量为N:319.58-371.48kg/hm2,P2O5:202.20-261.45kg/hm2,K2O:288.15-339.15kg/hm2时,花椰菜产量可达57000kg/hm2以上。

| Abstract: | The effects of nitrogen, phosphoric and potassium fertilizer on yield of cauliflower were studied with the design of general rotary combination regression. According to the data obtained, mathematic model was established. The results indicated that the yield of cauliflower was influenced significantly by nitrogen, phosphoric and potassium, the decreasing order of effects was: N>K2O>P2O5. Under the experimental condition, the suitable amounts of fertilizers for over 57000 kg/hm2 were N: 319.58-371.48 kg/hm2, P2P5: 202.20-261.45 kg/hm2, K2O: 288.15-339.15 kg/hm2. |
