节水型旱地小麦新品种铜麦6号高效施肥技术研究

Study on High Efficient Fertilization Technique of New Water-saving Wheat Variety Tongmai No.6 in Dryland

2012—2014年在铜川市印台区进行铜麦6号施肥技术对产量的效应研究,结果表明:秸秆还田与化肥配施比常规施肥处理有显著的增产效果,增产585 kg/hm^2,增幅12.0%;在传统施肥水平下,同时提高氮磷钾水平可显著提高产量,增产8.7%~17.7%,如果氮肥水平不变,增加磷和钾,产量变化不大,增产-0.5%~2.6%;铜麦6号最佳施肥方案为纯N 150 kg/hm^2,P_2O_5 75 kg/hm^2,K_2O 30.0kg/hm^2,最佳的氮,磷,钾的比例为1∶0.5∶0.2.

The study on the effect of fertilization technology on yield of Tongmai No.6 was conducted at Yintai district of Tongchuan city from 2012-2014.The results showed that straw returning and chemical fertilizer application have obvious effect on increasing yield than that of conventional fertilization treatment,the increase production is 585 kg/hm^2,and the increase is12.0%.Under the traditional fertilization level,the level of nitrogen,phosphorus and potassium will be improved simultaneously,and the yield can be improved significantly,and the yield will be increased by 8.7% ~ 17.7%.If the level of nitrogen fertilizer is constant,increasing phosphorus and potassium,the yield will not change,and the yield will increase by-0.5% ~2.6%.The optimum fertilization scheme of Tongmai No.6 is pure N 150 kg/hm^2,P_2O_5 75 kg/hm^2,K_2O 30 kg/hm^2,and the best ratio of nitrogen,phosphorus and potassium is 1∶ 0.5∶ 0.2.
