| 摘 要： | 通过试验及分析建立了春小麦滴灌次数、滴灌定额与作物产量及灌溉水分生产率的函数关系.在春小麦—玉米间作的模式下,设计了11个处理,3次重复,共计33个小区.通过试验及分析,建立了春小麦—玉米间作滴灌次数与玉米产量的函数关系.运用回归分析得到了间作玉米组分的滴灌条件下产量与全生育期灌溉定额的函数关系.根据试验结果,并得出了两种种植模式下的滴灌的优化灌溉制度,为大面积推广大田滴灌提供可靠的科学依据.

| Abstract: | The function of drip irrigation frequency,drip irrigation quota and crop yields,irrigation water productivity is established through the experiment values and data analysis.And thirty plots consisted of eleven experiment treatments and three times experiment repeat are designed for the wheat/maize intercropped.The function of drip irrigation frequency in the wheat/maize intercropped and maize yield is established through the experiment values and data analysis.And the function of maize yield and irrigation quota in whole growth period in wheat/maize intercropped under the condition of drip irrigation is gained with the regression analysis methods.Finally,the optimization of drip irrigation schedule in two planting patters is obtained based on the experimental results,which can provide the scientific basis for the spread of large-scale field of drip irrigation. |
