摘　　要：为了研究机械深松技术对大葱生长发育和产量的影响,在陕西乾县“漠西大葱”示范基地布置大田试验。通过连续两个年度试验表明大葱栽培使用机械深松技术后,土壤深松深度可达40~45 cm,与非机械深松大葱相比,平均每株葱高、次生根数量、根系长度、葱根以上10 cm葱白直径、葱白长度和葱重都有不同程度的增加,平均增产16.0%和31.6%。该研究为大葱生产推广应用机械深松技术提供了理论依据。同时在机械深松时必须保证土壤墒情良好,若墒情较差,需及时进行喷灌或浇灌,和墒时机械深松、开沟移栽。避免因土壤墒情差,深松后造成土壤疏松,开沟质量差,沟槽不成型,增加大葱移栽的难度,影响移栽质量。In order to investigate effect of mechanical subsoiling on yield of green Chinese onion,two years of field trial was conducted in‘Moxi’Green Chinese Onion Demonstration Base in Qianxian county.The results showed that the depth of subsoilling could reach 40-45 cm after application of mechanical subsoiling technology.Compared with non-mechanical subsoiling,the average of plant height,secondary root number,root length,10 cm scallion above onion root,scallion length and onion weight increased to varying degrees,the average increase in yield was 16.0 and 31.6 percent.This study provides a theoretical basis for extension and application of mechanical subsoiling technology in Chinese greeen onion production.At the same time,it is necessary to ensure good soil moisture when mechanical subsoiling technology was applied.If the soil moisture is poor,it is necessary to carry out irrigation or sprinkler irrigation in time to avoid poor soil moisture which caused the surface soil loose,poor quality trench,and not-formed grooves.Thus,it will increase the difficulty of Chinese green onion-transplanting and affect the quality of transplanting.
