| 摘 要： | 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。

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

| Abstract: | 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 0~100 cm 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 M50 G20 ,M60 G10 ,M40 G30 ,CK;the effects increase with the increase of rainwater harvesting surface width,reaches the greatest when the harvesting dragon face width is 50 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 M50 G20 works best and can enhance the economic benefits to the greatest extent. |
