摘  要：
为探讨三七的生态种植技术,研究三七/芋头间作模式对一年生三七生长的影响.采用田间小区试验,设置三七/芋头间作、三七单作两种种植模式.测定两种种植模式下三七的农艺性状、发病率、存苗率、叶片酶活性、叶片色素含量及土壤养分、微生物数量等指标.结果表明,三七/芋头间作较单作可有效促进三七生长,三七/芋头间作叶面积与壮苗指数分别显著提高19.67%和28.13%,存苗率提高10.33%,三七单作的发病率是三七芋头/间作的3.09倍;8~9月这段时间内,三七间作/芋头叶绿素a和叶绿素b分别是单作1.78倍和1.83倍,但三七单作叶片丙二醛(MDA)含量显著高于间作,叶片受害程度相对较大.间作模式下根际土壤细菌、真菌和放线菌数量相比于单作分别提高105%、176.3%和182.9%.此外,间作模式下土壤速效钾、有效磷和全钾含量均显著高于单作土壤,分别提高了 10.8%、15.77%和2.32%,但碱解氮含量显著降低19.82%.总之,三七/芋头间作可以增加土壤微生物数量并改善土壤养分状况,综合三七的生长状况可选择三七生态种植模式构建和应用.

摘  要：
In order to explore the ecological planting techniques of Panax notoginseng,the effects of intercropping patterns of Panax not-oginseng and taro on the growth of annual Panax notoginseng were studied.A field plot experiment was conducted to set up two planting modes,namely,intercropping of Panax notoginseng and taro,and monocropping of Panax notoginseng.Determine the agronomic charac-ters,incidence,rate seedling survival rate,leaf enzyme activity,leaf pigment content,soil nutrients,and microbial count of Panax notogin-seng under two planting modes.The results showed that the intercropping of Panax notoginseng and taro could effectively promote the gro-wth of Panax notoginseng compared with monocropping.Under the intercropping mode,the leaf area and healthy seedling index of Panax notoginseng were significantly increased by 19.67%and 28.13%,respectively,and the seedling survival rate was increased by 10.33%.The incidence rate of Panax notoginseng monocropping was 3.09 times that of Panax notoginseng/taro intercropping.During the period from August to September,the chlorophyll a and chlorophyll b of Panax notoginseng under the intercropping mode were 1.78 times and 1.83 times that of monocropping,respectively.However,the content of malondialdehyde(MDA)in the leaves of Panax notoginseng under mono-culture was significantly higher than that under intercropping,and the degree of leaf damage was relatively large.The number of bacteria,fungi,and actinomycetes in the rhizosphere soil under intercropping mode increased by 105%,176.3%,and 182.9%,respectively,compared to monocropping.In addition,the available potassium,available phosphorus,and total potassium content in the soil under intercropping mode were significantly higher than those in monocropping soil,increasing by 10.8%,15.77%,and 2.32%,respectively,but the alkali-hy-drolyzable nitrogen content was significantly reduced by 19.82%.In short,intercropping Panax notoginseng and taro can increase the num-ber of soil microorganisms and improve the soil nutrient status.Integrating the growth status of Panax notoginseng can promote the con-struction and application of an ecological planting mode of Panax notoginseng.
