我区中西部食用豆以绿豆为主,干旱、贫瘠、早春低温等是该地区的生态特点。干旱是影响食用豆产量的重要障碍因子,因干旱产生的水分胁迫效应对绿豆产量的降低作用大于其他自然灾害的总和。“十一五”期间,我们对地膜覆盖绿豆栽培做了系统的研究,基本明确地膜覆盖具有抗旱、保墒、提高地温、减少田间杂草和较好的增产作用,并进行较大面积的示范推广,但绿豆地膜覆盖栽培均采用玉米播种机播种覆膜,存在密度偏小,群体 The middle and western part of our region mainly uses mung bean as the edible bean, arid, barren and early spring low temperature are the ecological characteristics in this area. Drought is an important obstacle factor affecting the yield of edible beans. The water stress effect caused by drought reduces the output of mung bean more than the sum of other natural disasters. During the “Eleventh Five-Year Plan” period, we systematically studied the mulching cultivation of mulching mulch. It is basically clear that mulch mulching has the functions of drought resistance, soil moisture conservation, ground temperature improvement, field weed reduction and better yield increasing, and larger area Demonstration, but mung bean mulching mulching with corn seeder sowing, there is a small density, population
