摘    要:为探索免耕抛秧栽培水稻在一定产量范围内对氮肥的需求量,在磷、钾肥及管理水平相同的条件下,研究不同施氮量(10.5kg/667m2,11.55kg/667m2,13.6kg/667m2)对免耕抛秧栽培水稻生长及产量的影响[1,2]。结果表明:在各个阶段,水稻生长与氮肥施用量均密切相关,在本试验条件下产量与氮肥施用量呈正相关,其平均产量依次为489.25kg/667m2、496.50kg/667m2及503.25kg/667m2。

关 键 词:水稻  免耕抛秧栽培  施氮量

Abstract:In order to explore the demand of N fertilizer of rice NTSB within a yield scale,under the same P,K fertilizers and cultivation levels,different N fertilization amounts’impact(10.5kg/667m^2,11.55kg/667m^2,13.6kg/667m^2) on the rice growth and yield of NTSB was researched.The results show that in each growth stage,the rice growth and N fertilization amounts have a close relationship,which is the positive correlation under this experimental conditions,the yields are 489.25kg/667m^2、 496.50kg/667m^2 and 503.25 kg/667m^2 respectively.
Keywords:Rice  no-tillage and seedling broadcasting(NTSB)cultivation  N fertilization amounts
