间作玉米对丹参生长的影响

Effects of Intercropping Maize on Growth of Salvia miltiorrhiza

[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。

[ 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 ] Intereropping 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.
