不同施氮量对玉米新品种陕科10号产量及氮素利用率的影响

Effects of Different Nitrogen Application Rates on Yield and Nitrogen Utilization Efficiency of Maize Variety Shanke 10

陕科10号(陕审玉2014001号)是宝鸡迪兴农业科技有限公司选育的玉米新品种,由安徽丰大种业股份有限公司独家开发经营。近年推广实践证明,该品种具有高产优质、综合抗性较好等优点,适合在湖北省钟祥市大面积推广种植。该试验通过设置不同施氮量处理,研究陕科10号的氮素积累量、籽粒产量及氮肥利用效率对施氮量的响应,旨在为该品种在钟祥地区高产增效栽培中氮肥管理提供理论依据和实践参考。

Shanke No. 10 was a maize variety selected by- Baoji Dixing Agricultural Technology- Co., Ltd.The promo- tion practice in recent years has proved that this variety has the advantages of high yield, good quality and good com- prehensive resistance.It is suitable for large-scale planting in Zhongxiang city, Hubei Province.In this experiment, different nitrogen application rates were set to study the response of the nitrogen accumulation amount, grain yield, and nitrogen use efficiency of Shanke No. 10 to nitrogen application rates.The regional high-yield and efficiency-en- hancing nitrogen fertilizer management provides theoretical basis and practical reference.
