摘　　要：将生草栽培与菌根技术应用于柑桔生产中,有利于降低生产成本、提高果实品质、改善土壤理化性质和提高肥水利用率。本试验在盆栽条件下,通过研究白三叶草、黑麦草、百脉根和摩西球囊霉(AMF)等8个不同处理对枳实生苗及菌根生长的影响,筛选适于柑橘园间作的生草及菌根组合,为生草栽培+菌根技术应用提供参考。结果表明:生草栽培和接种AMF真菌促进了枳苗生长发育,增加了枳苗N、P、K含量(黑麦草除外),提高了枳苗根系AKP、ACP活性,促进了AMF菌根生长繁殖,提高了枳苗叶片中蛋白质含量和可溶性糖含量,提高了枳叶片内SOD、POD、CAT活性和降低了MDA的活性,其中栽培白三叶草及AMF组合的各项指标效果均最好,而只种黑麦草对枳苗的效果较差。因而,本研究表明白三叶草适宜于作柑橘园中栽培生草,而黑麦草不宜于栽植在柑桔园中。Applying the sod-culture cultivation and mycorrhizal technology in the citrus production,it may reduce the production cost,promote fruit quality,improve soil physical and chemical properties and enhance the utilization ratio of fertilizer.Effects of 8 different treatments of Trifolium repen L.,Lotus corniculatus L.,Lolium perenne L.and AMF on Poncirus trifodiata Raf.seedling and mycorrhizal growth under the pot cultivation experiment were studied in the present paper to screen the suitsble sod-culture and mycorrhizal combination in citrus orchard,and provide a reference for the application of sod-culture cultivation and mycorrhizal technology.The results showed that the sod-culture cultivation and AMF mycorrhizal could promote P.trifodiata Raf.seedling growth,increase P.trifodiata Raf.seedling N,P,K content （except Lolium perenne L.）,increase AKP,ACP activity in P.trifodiata Raf.seedling root,promote the growth and reproduction of AMF mycorrhiza,increase the contents of protein and soluble sugar in the leaves of P.trifodiata Raft.seedling,improve SOD,POD,CAT activity and reduce the activity of MDA in the leaves of P.trifodiata Raf.seedling.Among them,the Trifolium repen L.and its combination with AMF were the best in all treatments,but only planting Lolium perenne L.effect was poor.Therefore,this study suggests that the Trifolium repen L.is suitable for citrus orchards sod-culture,and L perenne L.is not suitable for being planted in citrus garden.
