摘　　要：试验探究了膜下水肥一体化种植方式和传统露天大水沟灌种植方式对丹参田间杂草生长的影响。结果表明,丹参水肥一体化种植的杂草生物量、杂草密度明显低于传统种植方式,其中生物量降低51.48%。该种植方式可减轻草害,节本增效。The experiment explored the influence of fertigation integrated cultivation under film and traditional cultivation by open ditch irrigation on the growth of weeds in the field of Salvia miltiorrhiza.The results showed that the density and biomass of weed were obviously lower under fertigation integrated cultivation compared with traditional cultivation,and the biomass decreased by 51.48%.Fertigation integrated cultivation could not only reduce the grass damage,but also save the cost and increase the efficiency.
