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
