摘　　要：为探索适合陕北旱地绿豆高产、高效的覆膜栽培方式,试验以榆绿一号为研究对象,设置全膜覆盖双垄沟播(T1)、膜际栽培(T2)、双沟覆膜(T3)、露地垄沟栽培(CK)共4个处理,分析不同覆膜方式下土壤温度、土壤含水量、产量指标的影响。结果表明:在绿豆全生育期,覆膜栽培处理土壤含水量均高于CK处理,在0~20 cm土层中,T2处理含水量显著高于其他各处理16.53%~80.89%(P<0.05)。在绿豆生育中后期,T2处理的土壤温度低于其他两种覆膜处理1.19%~16.26%。T2处理的绿豆单株荚数、单株粒数最高,其产量最高,且显著高于其他处理6.63%~50.78%(P<0.05)。综上,膜际栽培下为绿豆营造了适宜的土壤水热环境,促进绿豆生长,绿豆产量最高,建议在陕北旱区绿豆生产中推广使用膜际栽培技术。In order to explore a high-yield and efficient mulching cultivation method suitable for mung beans in arid areas of Northern Shaanxi,the experiment took Yulv No.1 as the research object,and set up four treatments:full film covering double ridge sowing(T1),film intercropping(T2),double ditch film mulching(T3),and open field ridge cultivation(CK).The effects of different mulching methods on soil temperature,soil moisture,and yield indicators were analyzed.The results show that during the entire growth period of mung beans,the soil moisture of the mulching cultivation treatment is higher than that of the CK treatment.In the soil layer of 0~20 cm,the moisture of the T2 treatment is significantly higher than that of the other treatments,ranging from 16.53%to 80.89%(p<0.05).In the later stage of mung bean growth,the soil temperature of T2 treatment is 1.19%~16.26%lower than the other two mulching treatments.The T2 treatment has the highest number of pods and grains per plant in mung beans,resulting in the highest yield,which was significantly higher than other treatments by 6.63%~50.78%(p<0.05).In summary,under membrane cultivation,a suitable soil water and heat environment has been created for mung beans,promoting their growth and achieving the highest yield.It is recommended to promote the use of membrane cultivation technology in mung bean production in the arid areas of Northern Shaanxi.
