| 摘 要： | 试验采用二次回归饱和设计方法,研究了氮、钾、锰、硼肥和芸薹素内酯、乙烯利对甜菜根产量和含糖率的影响,建立了以根产量和含糖率为目标的回归方程。研究结果表明:氮、钾、锰、硼肥和芸薹素内酯、乙烯利的合理配合施用能使甜菜产量明显提高,品质得到显著改善。通过模拟寻优,决选出了根产量67704.46kg/hm2,含糖率22.3%以上的调控措施为:在施用P2O5150kg/hm2基础上,施纯N 119.85kg/hm2,K2O 144.79 kg/hm2,纯Mn 5.26 kg/hm2,纯B 1.16 kg/hm2;叶面喷施BR和ETH,浓度分别为10.42mg/L和225.58mg/L。

| Abstract: | The experiment was undertaken to determine the effect of six elements nitrogen,potassium,manganese,boron,brassinolide(BR) and ethephon(ETH)] on root yield and sugar content of sugarbeet by the second regression saturating optimal design,and to establish two regression equations on root yield and sugar content of sugarbeet.The results showed that combined application of the six elements could increase yield and improve the quality of sugarbeet.Through simulation by these equations,the decision-making project for producing 67704.46k g/ha of root yield and 22.3% of sugar content was pure nitrogen 119.85 kg/ha,P2O5 150 kg/ ha,K2O 144.79 kg/ha,pure manganese 5.26 kg/ha,pure boron 1.16 kg/ha.In different growth period,10.42 mg/L BR and 225.58 mg/L ETH solution would be sprayed on the leaf surface of sugarbeet. |
