摘要:

为了解宁波市当前主要配方肥在单季籼粳杂交稻上的增产增效效果,以‘甬优7850’为材料,设置3种配方肥施肥方案,以常规复合肥为对照,探索经济效益最佳的施肥方法。结果表明:与常规复合肥纯氮用量接近时,专用配方肥处理生长表现较好,群体结构协调,成穗率较高,最终产量最高,同时节本增效效果显著,具有较好的增产增效效果,适合在当地推广应用。

Abstract:

The study aims to clarify the effect of current formulated fertilization on indica-japonica hybrid rice production. Indica-hybrid rice ‘Yongyou7850’ was used as material, three formulated fertilization schemes including the control (CK, the conventional compound fertilization) were employed in the field experiment. The results showed that compared with the CK, the current formulated fertilization scheme had a better performance on yield when the same N amount was applied, due to the healthy growth, reasonable population structure, and more effective panicles. In addition, the cost of fertilization was obviously decreased, while the yield was significantly increased. Thus, the current formulated fertilization scheme is suitable for popularization and application in Ningbo.

Key words: formulated fertilization, indica-japonica hybrid rice, single cropping rice, increasing production and efficiency
