不同施肥方式及用量对油研5号产量的影响

摘要

[目的]探讨不同施肥方式及用量对油菜产量及效益的影响。[方法]以油研5号为供试品种，设置6个处理，采用随机区组设计，开展田间试验。[结果]以施用有机肥为1500 kg／hm2，N、P2 O5、K2 O分别为180、90、150 kg／hm2的处理油菜产量最高、经济效益最好，油菜实收产量和纯收入分别为2453 kg／hm2和3683元／hm2。[结论]有机肥、无机肥配合施用可提高油菜产量和品质。%Objective] To study the effects of different fertilizer modes and dosages on the yield and benefit of rape .[ Method] With Youyan 5 as the test varieties, 6 treatments were designed.Randomized block design was adopted to carry out field test .[ Result] Rape yield was the maximum under 1 500 kg/hm2 organic fertilizer, 180 kg/hm2 N, 90 kg/hm2 P2 O5 and 150 kg/hm2 K2 O.And the economic benefit was also the maximum.The actual yield and net income of rape were 2 453 kg /hm2 and 3 683 yuan/hm2, respectively.[Conclusion]Combination of organic and inorganic fertilizers enhances the yield and quality of rape.
