摘要: 文章以粳稻连粳7号为试验材料,研究了4种不同氮肥处理对水稻生理效应及产量的影响。结果表明:处理C、处理D光合生理指标高于处理B和对照处理A;处理B、处理C、处理D和对照处理A相比产量分别增加38.78%、53.63%和54.15%;抗倒伏机械强度为处理A的109.49%、132.61%和86.55%;处理C的水稻抗倒伏能力最强,产量较高;综合产量、抗倒伏能力及生产成本等因素考虑,处理C(氮肥300kg/hm^2+磷肥67kg/hm^2+钾肥135kg/hm^2)为最优处理。

Abstract: The effect of 4 different nitrogen treatments on the physiological effect and yield of rice was studied with japonica rice, Lian Jing No.7 as the test material. The results showed that photosynthetic indexes of C, D,were higher than that of treatment B and treatment A (control);treatment B, treatment C, treatment D and compared with treatment A (control); yield increased by 38.78%, 53.63% and 54.15%, lodging and mechanical strength with 109.49%, 132.61% and 86.55% as much as treatment A,treatment C with strongest lodging resistance and a high yield; considering yield, lodging resistance and production costs and other factors,C(N 300 kg/hm^2+ P 67 kg/hm^2+ K 135 kg/hm^2) is optimal treatment.
