| 摘 要： | 通过对中药材桃儿七在定植前施用不同氮与磷配比组合的肥料试验,探讨了施肥对桃儿七产量的影响.结果表明,施用氮(N)75～225 kg/hm2、磷(P2O5) 150～225 kg/hm2,可获得较高的桃儿七产量,增产幅度比不施肥料的提高1倍以上；氮(N)与磷(P2O5)的配比在1∶1～1∶2,则桃儿七在田间的长势较好,增产效果明显,从投入产出比的角度来看也比较科学合理.建议在目前人工栽培桃儿七的大田管理水平前提下,采用氮(N)与磷(P205)的配比在1∶1～1∶2,于桃儿七定植前施入,可获得较佳的经济收益.

| Abstract: | Different combination of nitrogen(N) and phosphorus(P2O5) fertilizer was applied on Chinese herbal medicine Sinopodophyllum emodi(Wall.ex Royle) Ying before field planting to study the effects of fertilization on yield of S.emodi.The results showed that high yield of S.emodi could be obtained when dose of N and P2O5 was 75～225 and 150～225 kg/hm2,respectively.The yield was more than twice of that without fertilizer application.When the ratio of nitrogen(N) and phosphate(P2O5) was 1∶1～1∶2,the field growth of S.emodi was better with great yield increasing effect were obvious and reasonable input and output ratio.It was suggested that the nitrogen(N) and phosphate(P2O5) should be applied before transplanting with the ratio of 1∶1～1∶2 under current artificial cultivation management of S.emodi to obtain better economic benefits. |
