不同集雨垄面和垄沟宽度对马铃薯产量和土壤含水量的影响

Effects of Different Rainwater Harvesting Ridge and Furrow Width on Yield and Soil Water Content

研究了不同覆膜集雨垄面和垄沟宽度对土壤含水量、产量、商品薯率和产量WUE的影响。试验结果表明,对0~100cm土层土壤含水量的影响是随着集雨垄面宽度的增加而增加;对产量WUE、产量和商品薯率的影响具体表现为M_（50）G_（20）〉M_（60）G_（10）〉M_（40）G_（30）〉CK,随着集雨垄面宽度的增加,影响是先增加,当集雨垄面宽度为50cm,垄沟宽度为20cm时影响最大,而后随着集雨垄面宽度的增加影响逐渐降低。综合分析,初步推出M_（50）G_（20）这种模式集雨效果最好,能最大程度增加经济效益。

This paper studies the effects of different mulching and rainwater harvesting ridge and furrow width on soil moisture,yield,commodity potato rate and yield WUE.The results show that：the soil moisture content of 0~100cm soil layer increases as the harvesting and the width of the ridge increase;the order of the effects of different harvesting modes on the yield WUE,yield and commodity potato rate specific performance from big to small is M_（50）G_（20）,M_（60）G_（10）,M_（40）G_（30）,CK;the effects increase with the increase of rainwater harvesting surface width,reaches the greatest when the harvesting dragon face width is cm and the furrow width is_（20）cm,and then gradually decreases with the increase of the harvesting dragon face width.Through comprehensive analysis,it is found that the harvesting mode of M_（50）G_（20）works best and can enhance the economic benefits to the greatest extent.
