| 摘 要： | 为明确减氮配施有机肥对垦鉴稻6号氮肥利用率和产量效益的影响,采取随机区组设计进行试验研究。结果表明,相对常规化肥处理,在施用有机肥300 kg·hm-2基础上,减氮10%、15%时不仅有利于水稻氮素积累的增加,而且氮肥农学利用率、吸收利用率得到显著提高,产量更是高达9.69 t·hm-2、9.44 t·hm-2,较对照分别提高了5.3%、2.6%,其中减氮10%较对照增加的纯效益为256.1元·hm-2,产出效益达到最高。

| Abstract: | Single-factor and randomized block design experiments were employed to confirmed the influences of nitrogen fertilizer utilization rate and yield benefit of Kenjiandao6.The results showed that,on the basis of applying 150 kg/hm^2 organic fertilizer,reducing nitrogen by 10%and 15%is not only beneficial to the increase of nitrogen accumulation in rice,but also to the improvement of agronomic utilization rate and absorption utilization rate.The yield was 9.69 t/hm^2 and 9.44 t/hm^2,which were 5.3%and 2.6%higher than the control respectively.The net benefit of 10%nitrogen reduction was 856.1 yuan/hm^2,and the output benefit was the highest. |
