摘  要：
2018年5月至7月,在内蒙古农业大学牧草试验地,进行了草原3号杂花苜蓿(Medicago varia Martin.cv.Caoyuan No.3)大田扦插试验。使用主要成分为生长素的生根粉对草原3号杂花苜蓿进行处理,实验设置为3个不同的浸泡时间(2h,5h,10h),4个不同的生长素溶液浓度(100ppm,200ppm,500ppm,0),加不做任何处理做对照。共计15个组合处理。结果表明:7号组合处理的成活率和生根率最高,成活率达73.3%,生根率为95.4%。此时生长素溶液浓度为200ppm,插条被浸泡了5h。所以,最适宜草原3号杂花苜蓿扦插的生长素浓度为200ppm,最合适的浸泡时间是5h。本实验可为呼和浩特市的大田应用扦插技术提供一部分参考。

摘  要：
From may to July 2018,the field cutting experiment of(Medicago variamartin.cv.CaoyuanNo.3)was carried out in the herbage experimental field of Inner Mongolia agricultural university.The root powder with the main component of auxin was used to treat grassland no.3 mixed alfalfa.The experiment was set as 3 different immersion time(2 h,5 h,10 h)and 4 different auxin solution concentrations(100 ppm,200 ppm,500 ppm,0),and no processing was added as the control.A total of 15 combinedprocessing.The results showed that No.7 combination treatment had the highest survival rate and rooting rate,with 73.3%survival rate and 95.4%rooting rate.At this time,the auxin solution concentration was 200 ppm,and the cuttings were soaked for 5 h.Therefore,the most suitable auxin concentration for grassland no.3 mixed alfalfa cutting was 200 ppm,and the most suitable soaking time was 5 h.This experiment can provide some reference for the application of cutting technology in Hohhot.
