| 摘 要： | 甜菜叶丛繁茂期是前期生长中心.繁茂期叶面积与块根产量、含糖率呈强正相关(r=0.9616**、0.9588**);生长期积温与块根产量亦呈强正相关(r=0.7242**).优化模型指出,3月底前是甜菜适宜播期;氮、磷、钾分别总投入484.5、169.05、75kg/hm2,产量达75t/hm2.

| Abstract: | The stage of leaf luxuriancy was the growth center of sugar beet in the earlier stage.1n this stage, leaf areas and yields of root tuber,sugar content showed extremely positive relationships (r=0.9616**,0.9588**).Accumulative temperature during growing period and yeilds of root tuber also showed an extremely positive relationship (r=0.7242**).The optimum model indicated that when applications of N,P,K were 484.5,169.05 and 75 kg/hm2 respectively,the output of beet would be 75 t/hm2. |
