Abstract
Chemical fertilizers,especially nitrogenous fertilizer,have played an important role on increasing paddy rice production. In this research,field experiment with 7 fertilizers under 225 kg/hm2 nitrogen amount and five high-yielding medium hybrid rice varieties has been conducted. Results showed that there were significant difference on nitrogen accumulation of leaf (NAL),nitrogen accumulation stem (NAS) and total nitrogen accumulation (TNA) between the compound application of the inorganic and organic fertilizer in A7,A6 and A5 with the corresponding treatments A2,A3 and A4. Varieties difference was showed mainly on NAL and TNA at the late development stages. Nitrogen harvest index (NHI) of A6 was highest,15.2% higher than no compound application with organic fertilizer treatment A5. Leaf and stem nitrogen apparent translate ratio (NATR) of A3 was highest,6.1% and 9.53% higher than A2 and A5,respectively. The nitrogen use efficiency (NUE) increased by 10% through compound application organic fertilizer. The biomass and grain yield of A4 were higher than those of the other treatments,50.6% and 16.4% higher than A1,respectively. Thus,the compounding organic fertilizer as base fertilizer was applied in favor of the nitrogen accumulation of leaf,stem and total plant. NATR was no significant difference in fertilizers test and higher yield varieties. The compound organic fertilizer can significantly increase NUE and NHI.
