摘要
本文以‘宜香优2115’水稻品种为试验材料,设置6个控释氮肥替代普通尿素处理和1个对照处理,比较不同施肥处理水稻产量及氮肥利用率。结果表明:控释氮肥的施入有助于提升水稻产量及氮肥利用率。60%尿素+40%控释氮肥配施水稻产量及氮肥利用率为最高,是最适宜陕西省汉中市水稻种植的施肥模式。
This study used the rice variety'Yixiangyou 2115'as the experimental material,setting up six treatments with controlled-release nitrogen fertilizer replacing regular urea and one control treatment to compare rice yield and nitrogen fertilizer use efficiency under different fertilization treatments.The results showed that the application of controlled-release nitrogen fertilizer helps to increase rice yield and nitrogen fertilizer use efficiency.The combination of 60% urea and 40% controlled-release nitrogen fertilizer achieved the highest rice yield and nitrogen fertilizer use efficiency,making it the most suitable fertilization method for rice cultivation in Hanzhong City,Shanxi Province.
