摘要
以厚朴林下黄连单作(CC)、林下湖北贝母-黄连间作(FH-CC)及玄参-黄连间作(SN-CC) 3种种植模式为研究对象,分析间作模式对黄连生理生长特性及根际土壤理化性质的影响。结果表明:相比于CC模式,SN-CC模式及FH-CC模式下黄连的株高、植株鲜重、叶面积、过氧化物酶活性的增幅分别为(19.56%、14.70%)、(91.38%、4.86%)、(28.86%、16.63%)和(47.10%、37.46%);SN-CC和FH-CC间作模式下黄连生理生长综合指数分别为0.413和0.007;林下间作模式黄连的生长性状优于单作模式,间作模式有利于黄连的生长,且玄参-黄连间作模式效果更佳;林下间作模式改善了土壤理化性质,进而促进了黄连的生长;土壤理化性质显著影响黄连的生理生长性状,且黄连根际土壤酶活性显著影响其根际土壤养分含量;蔗糖酶活性、速效钾含量及碱性磷酸酶活性(相关系数分别为0.9999、0.9639、0.9094)是影响黄连生长的主要土壤因子。
We investigated the effects of intercropping patterns on physiological and growth traits of Coptis chinensis and rhizospheric soil physicochemical properties under three intercropping systems [Magnolia officinalis-C. chinensis(CC),M. officinalis-Fritillaria hupehensis-C. chinensis(FH-CC),and M. officinalis-Scrophularia ningpoensis-C. chinensis(SN-CC) cropping systems]. Results showed that plant height,fresh weight,leaf area and peroxidase activity of C.chinensis in the intercropping modes(SN-CC system and FH-CC system) were(19. 56%,14.70%),(91.38%,4.86%),(28.86%,16.63%) and(47.10%,37.46%) higher than those in the CC system,respectively. The physiological/growth comprehensive index of C. chinensis under SN-CC system and FH-CC system was 0. 413 and 0. 007,respectively. Growth traits of C.chinensis in the intercropping systems were better than those in the monoculture. The intercropping systems were beneficial to the growth of C. chinensis,with SN-CC system being the optimal.Soil physicochemical properties significantly affected the physiological and growth traits of C.chinensis. Enzyme activities of C. chinensis rhizosphere soil significantly affected soil nutrient contents. Sucrase activity,available potassium content and alkaline phosphatase activity were the main soil factors affecting the growth of C. chinensis,with a correlation coefficient of 0. 9999,0.9639 and 0.9094,respectively.
