| 摘 要： | 通过田间试验,在宁夏区盐池县研究了油葵田施用氮、磷、钾肥的效应。结果表明:在中等肥力的条件下(地力贡献率为68.63%),增产效应居首位的为氮肥,施用纯N150 kg/hm2的增产量达到376.65 kg/hm2;施用纯K135 kg/hm2的增产量为246.0 kg/hm2;施用纯P2O575 kg/hm2的增产量达到129.6 kg/hm2。3种养分单位养分增产量以纯N最高,为每千克2.51 kg。纯收入以全肥区(施用N150 kg/hm2、P2O575 kg/hm2、K2O 135 kg/hm2)最高,为6780.00元/hm2。

| Abstract: | The effects of nitrogen,phosphorus and potassium fertilizer application in oil sunflower field in Yanchi county,Ningxia municipality were studied through field trials.The results showed that the contributive rate of the basic fertility of the experimental field was 68.63%,and its soil fertility was moderate.The yield-increasing effect of nitrogen fertilizer application was the greatest,the oil sunflower yield increments caused by the application of 150 kg/hm2 pure nitrogen,135 kg/hm2 pure potassium and 75 k... |
