摘要:

为探索水稻减肥增效技术,用水稻缓释肥搭配腐殖酸尿素开展大田试验,设置4个减肥处理(T1、T2、T3、T4)、1个常规施肥处理(T5)、1个空白对照(T6),分析不同处理的水稻嘉优中科3号的产量、经济效益与肥料利用率。结果表明,与T5处理相比,T1、T2、T3处理的产量都有所增加,T4处理产量降低,T1、T2、T3、T4处理的经济效益、肥料偏生产力和氮肥偏生产力均提高。施氮量是影响水稻产量的关键因子,而P2O5和K2O的施用量对水稻嘉优中科3号产量、经济效益没有太大影响。本研究为水稻嘉优中科3号的优化减肥增效技术提供了理论依据。

Abstract:

To explore fertilizer reduction and efficiency enhancement technology in rice, a field experiment was conducted using slow-release fertilizer combined with humic acid urea. Four reduced-fertilizer treatments (T1, T2, T3, T4), a conventional fertilization treatment (T5), and a blank control (T6) were designed. The yield, economic benefit, and fertilizer utilization efficiency of the rice cultivar Jiayou Zhongke 3 were evaluated under each treatment. The results showed that compared with the T5 treatment, the yields of T1, T2, and T3 treatments increased, while the yield of T4 treatment decreased. All reduced-fertilizer treatments (T1-T4) exhibited improved economic benefit, partial fertilizer productivity, and partial nitrogen productivity. The amount of nitrogen application was the key factor affecting rice yield, while the application of P2O5 and K2O had little impact on the yield and economic benefits of Jiayou Zhongke 3. This study provides a theoretical basis for optimizing fertilizer reduction and efficiency enhancement technology for Jiayou Zhongke 3.
