| 摘 要： | 对重庆市梁平县24个乡镇,36个试验点进行了水稻“3414”施肥试验,研究分析了梁平县水稻的氮磷钾施肥技术,建立数字回归方程,寻找水稻的最佳施肥模式,为实现梁平县水稻生产的高产高线提供科学依据.结果表明:在低肥力土壤上N、P、K对水稻产量的影响大小顺序为N＞K＞P,在中、高肥力的土壤上表现为N＞P＞K；NP、NK、PK对水稻产量的交互效应均表现为正交互效应；在试验区低肥力土壤中,试验区水稻的最佳施肥配比为N:P2O5:K2O=1:0.4 ～0.6:0.4 ～0.6;在中肥力土壤中,其最佳施肥配比为N:P2O5:K2O =1:0.6:0.6；在高肥力土壤中,其最佳施肥配比为N:P2O5:K2O=1:0～0.6:0～0.6.

| Abstract: | The ’3414’experiments of rice were designed in 24 towns,36 test locations in Liangping County.The fertilizer technology of NPK on rice in hilly area was studied to find the best fertilizer technology and establish the regression equation,and obtain the high efficiency program by analyzing the equation,which could provide the scientific evidence for high and stable yield on rice in Liangping County.The results showed that: in the low fertility soil,the effect of nitrogen,phosphorus,and potassium on the output of paddy rice field was N>K>P.in the middle and high fertility soil,the effect of nitrogen,phosphorus,and potassium on the output of paddy rice yield was N> P > K.In the experiment area soil,the effects of NP,NK,PK on rice yield had positive interaction.In the low,middle and high fertility soil,the optimum application ratio of N∶ P2O5∶ K2O was 1∶ 0.4-0.6∶ 0.4-0.6,1∶ 0.6∶ 0.6,and 1∶ 0-0.6∶ 0-0.6. |
