摘要
通过田间试验研究不同施肥处理对水稻产量、品质和经济效益的影响,从而确定水稻最佳施肥组合及产量限制因子。结果表明:限制该地产量的因子主要在氮和磷,N∶P2O5∶K2O=21∶7.4∶10.5的最佳施肥组合为合理施肥量,但不是最佳量,此结果还有待进一步试验验证。
The experiment was conducted to study the effect of different fertilization on yield,quality and benefit of rice,and to determine the optimum fertilization combination and yield restricting factors.The results showed that the phosphorus and nitrogen were the main yield limiting factors.The best fertilization combination was N∶P2O5∶K2O being 2.1∶7.4∶10.5.However,the optimum fertilizing amount is required to fid out.
