| 摘 要： | 为了探明密度和氮、磷、钾肥对德新油18产量的影响,采用正交试验研究了油菜新品种德新油18不同种植密度和氮、磷、钾肥的效应。结果表明:施尿素12 kg/667 m2比4 kg/667 m2的处理增产17.4 kg/667 m2,施用高氮肥处理的产量高于低氮肥,磷肥和钾肥对产量的影响不大;主花序长度随密度的增加而缩短,有效分枝高度随密度的增加而升高,一次分枝数、二次分枝数、单株有效角果数、角粒数和单株理论产量均随密度增加而减少,千粒重变化不大;德新油18油菜新品种在试验过程中有一定菌核病发生,但不同处理间的差异不明显。

| Abstract: | Research response of consistency and nitrogen,phosphorus,potassium fertilizer on yield of deixinyou 18 to using of orthogonal experimental design.It was studied under 6667/667 m2、5000/667 m2、4000/667 m2 and 3333/667 m2 four different density levels;set up N,P,K at two levels;The experiment was determined by the randomized blocks design of three replications.The results showed that: Yield per plant was negatively related to the consistency,Yield per unit of area and is positive linear correlation to consistency;Yield increase 322 kg/hm2 by use carbamide 82.8 kg/hm2 than use carbamide 27.6 kg/hm2;It make basically no difference to yield of rape by phosphorus,potassium fertilizer. |
