| 摘 要： | 以汕优63和淮稻9号为试材,设置不同氮肥管理模式,研究其对水稻产量和氮素利用率的影响。结果表明,与农民习惯法(FFP)相比,实地氮肥管理模式(SSNM)增产6.32%(汕优63)和3.3%(淮稻9号),SS-NM的氮肥产谷效益和农学利用率分别较FFP提高了35.68%(汕优63)、40.48%(淮稻9号)和172.61%(汕优63)、154.50%(淮稻9号),SSNM的氮素转运率显著高于FFP。说明在产量不降低甚至有所增加的前提下,实地氮肥管理可减少氮肥施用量,并较大幅度地提高水稻氮肥利用率。

| Abstract: | Taked Shanyou 63 and Huaidao 9 as materials,effects of site-specific nitrogen management(SSNM) on rice and nitrogen use efficiency in rice were studied.The results showed that SSNM increased the grain yield by 6.32% in Shanyou 63 and 3.30% in Huaidao 9,grain production efficiency of nitrogen increased by 35.68% in Shanyou 63 and 40.48 in Huaidao 9 respectively,and agronomic efficiency of nitrogen increased by 172.61% in Shanyou 63 and 154.50% in Huaidao 9 respectively,compared with those under farmer fertil... |
