摘要
[目的]研究间作玉米对丹参生长的影响,为有效解决粮药之间的争地矛盾,缓解连作障碍提供科学依据.[方法]丹参采用大垄双行种植,以不同的间作玉米行距(60、120、180、240 cm)为试验因素,以丹参单作为对照,比较间作玉米对丹参株高、冠幅、生物量、经济产量、根长、根粗、根条数等的影响.[结果]在丹参田间作玉米对丹参的地上部和地下部都具有明显的影响,这种影响随着玉米种植密度的增加更加明显.[结论]玉米行距为180～ 200 cm,株距为25 cm,丹参能够正常生长,获得理想产量和间作的整体效益.
Abstract
[Objective] To study effects of intercropping maize on growth of Salvia miltiorrhiza,and to provide scientific basis for effectively solving the contradiction between food and medicine to alleviate the obstacles of continuous cropping.[Method] With different row spacing (60,120,180,240 cm) as factors and sole cropping Salvia miltiorrhiza as control,effects of intercropping maize on plant height,crown breadth,biomass,economic yield,root length and diameter,root number were compared.[Result] Intercropping maize had significant influence on aboveground and underground parts of Salvia miltiorrhiza,the influence was more obvious with the increase of planting density.[Conclusion] Salvia miltiorrhiza can grow normally and obtain ideal yield and overall benefits of intercropping when maize was cultivated with spacing between rows 180-200 cm,spacing in rows 25 cm.
