| 摘 要： | 以玉米和穿心莲为试验材料、采用二因素裂区设计,设主区玉米品种因子为A共3个水平,副区穿心莲套种密度因子为B共5个水平,探讨玉米与穿心莲套种时玉米品种与穿心莲密度对玉米和穿心莲产量的影响。结果表明:玉米品种对穿心莲产量没有明显影响;穿心莲套种密度对穿心莲产量有显著影响但对玉米产量没有明显影响。桂单0810和迪卡007以套种穿心莲密度为1.2万株/667m2时穿心莲产量最高、经济效益最好;兆丰788则在1.1万株/667m2时穿心莲产量最高、经济效益最好。

| Abstract: | An intercropping experiment that mixed maize with Andrographis paniculata （Burm.f.）Nees in different planting density was conducted to explore the interaction effects of maize vareity and the herb plant- ing density on yield.This experiment was adopted by split plot design which included two factors, main treat- ments A was treated with three maize varieties levels and vice treatments B was treated with five planting density ofA ndrographis paniculata（Burm.f. ）Nees. The results show as follows： the effect of maize variety on the yield of A ndrographis paniculata （Burm.f.）Nees was not significant. The effect on the yield of A ndro- graphis paniculata （Burm,f.）Nees from its planting density was significant. Guidan 0810 and Dika 007 ob- tained the highest yield and economic benefits with the intercropping density of 12000 plants per 667 m^2 of Andrographis paniculata （Burm.f.）Nees, and Zhaofeng 788 had the best result with the density of 11000 plants per 667m^2. |
