| 摘 要： | 以甜瓜为供试材料,采用二次回归通用旋转组合设计,在宁夏中部干旱带进行了老压砂地配方施肥效应试验,研究了非充分补灌条件下氮、磷、钾不同用量配比对甜瓜产量的影响,并建立了相应的回归模型。研究结果表明,影响甜瓜产量的顺序为磷〉氮〉钾,交互作用均不显著;经模型寻优,得出不同目标产量下的氮、磷、钾最佳组合方案,为降低甜瓜生产成本...

Balanced Fertilization on the Yield for Melon in Old Sunada |

| Abstract: | In this paper,melon is the object of our research in gravel mulched field.Based on the experiment of the current rotary combination design of square regression of 3 factors with 5 levels,the regression model of effects of N with P2O5 and K2O fertilizers with melon yields under the conditions of Non-sufficient irrigation was established.The main and single-factor effects and interactions of the model were studied.The optimum combination schemes of N with P2O5 and K2O fertilizers under different yields were obtained through the model. |
