| 摘 要： | 水稻优化施肥技术主要依据土壤供肥能力和水稻的目标产量来确定N、P、K肥的总用量,利用叶龄来确定水稻生育期,在主要生育期,根据叶色卡的数值确定N肥追施量,以最大限度地满足水稻高产群体各个时期对养分的需求,达到目标产量。超高产试验(SSNM_2)达到716.7 kg/667 m~2,比农民习惯施肥增产173.8 kg/667 m~2,增加效益234.3元/667 m~2。

| Abstract: | The optimized fertilization is to determine total N,P,and K application amount based on fertility supply ability of soil and target yield of rice,to determine growth stage of rice by leaf age and to apply N fertilizer amount to meet the nutrient requirement of all growth stages at best and reach high yield.In this study,the yield reached 716.7 kg/667 m~2 in super high yield trial,increasing by 173.8 kg/667 m~2 over traditional fertilization with a benefit increase by 234.3 yuan/667 m~2. |
