| 摘 要： | 选用生产上广泛应用的尿素、磷酸二铵为试材,探讨肥料对黑土区甜菜株高、出叶速度、叶面积、根重、含糖率、净光合生产率的影响,为指导合理施肥提供理论依据。试验结果表明,尿素对甜菜株高、叶片数、叶面积、根重等影响较大,磷酸二铵对其影响较小;尿素对根产量的增产作用约是磷酸二铵的2 倍;尿素、磷酸二铵配合施用效果最好。

| Abstract: | In this study,nitrogen fertilizer(urea)and phosphate fertilizer(ammonium hydrogen phosphate) used widely in agricultural production ,these were selected as basic material to determine the influence of fertilizers on sugarbeet plant height,leaf growth rate,leaf area,root weight,sugar content and net photosynthes's productivity in black soil region.Thus,it provide theory basis for reasonable application of fertilizer.Results showed that urea has much effect on sugarbeet plant height,leaf number,leaf area,root weight,etc.but ammonium hydrogen phosphate has less effect on those positive effect of urea on root yield is about two times as that of ammonium hydrogen phosphate.The mixed fertilizer of urea and ammonium hydrogen phosphate is the best. |
