摘　　要：以绿豆品系1111-34为试验材料,采用二因素完全随机区组设计,研究覆膜以及不同种植密度对旱地绿豆产量及其相关构成因素的影响。结果表明,覆膜处理明显提高了耕层的地温,具有良好的增温保墒作用;随着种植密度的增加,土壤含水率也随之提高,均有利于旱地绿豆产量的提高。覆膜种植相比于露地种植产量提高了26.50%;随着种植密度的增大,产量也随之增加,当种植密度为22.5万株/hm^2时,产量达到最大。覆膜+种植密度22.5万株/hm^2的种植模式更有利于发挥绿豆的高产潜力。With mung bean strain 1111-34 as the experimental materials,a two-factor completely randomized block design was used to study the influence of film mulching and different planting densities on dryland mung bean yield and related factors.The results showed that the film mulching treatment significantly increased the ground temperature of the cultivated layer,and had a good effect of increasing temperature and moisture preservation.With the increase of planting density,the soil moisture content also increased,which was beneficial to the increase of the yield of dryland mung bean.The yield of film mulching planting increased by 26.50%,compared with open field planting.With the increase of planting density,the yield also increased.When the planting density was 2.25×10^5 plants/hm^2,the yield reached the maximum.Therefore,the planting mode of film mulching+planting density of 2.25×10^5 plants/hm^2 is more conducive to the high-yield potential of mung bean.
