将砖瓦场采土后破坏的土壤装入盆内,每盆加入 N P K 复合肥(10∶5∶10)0,50 μg·g- 1和100 μg·g- 1,并接种丛枝菌根真菌( A M F) Gigaspora albida, Gigaspora sp 1, Glom us m osseae 109, Glom us versiform e, Scutellosp ora calospora 和 Scuteosp ora verrucosa 接种物(孢子和感染菌根的根段)0 和20 000 接种势单位/盆,然后播种三叶草( Trifolium repens)。植株生长5 个月以后收割并翻压入土壤中。第 2 年于此土壤中重复这一试验。当植株在土壤中完全腐烂后,测定土壤 p H 值和矿质元素含量。结果表明接种 A M F能显著增加植株的干、鲜重及体内 N, P, K, Zn 和 Cu 的含量,及土壤中有效 P, Zn, Cu 和总 N 的含量。 Glom us m osseae, Glom us versiform e, Gig asp ora albida 和 Scutellosp ora calosp ora 比其他菌种更有效。接种和施肥能改变根围土壤p H 值。接种 A M F 并配和施肥处理的效应
The soil was crushed to remove the soil from the brickyard. Each pot was supplemented with 0, 50 μg · g-1 and 100 μg · g-1 NPK fertilizer (10:5:10) Mycorrhizal fungi (AMF) Gigaspora albida, Gigaspora sp 1, Glomus m osseae 109, Glover versiform e, Scutellospora calospora and Scuteospora verrucosa inoculum (root segments of spores and infected mycorrhiza) 0 and 20 000 inoculation unit / pot, and then sowing Trifolium repens. Plants are harvested and pressed into the soil after 5 months of growth. The second year in this soil to repeat this test. After the plants were completely decayed in the soil, soil p H values and mineral element contents were determined. The results showed that inoculation with A M F could significantly increase plant dry weight, fresh weight, N, P, K, Zn and Cu contents and available P, Zn, Cu and total N contents in soil. Glomus m osseae, Glomus versiform e, Gig asp ora albida and Scutellospora calospora are more effective than other species. Inoculation and fertilization can change p H values in the rhizosphere soil. Effect of inoculation with AMF and fertilization
