| 摘要: |
| 本研究采用三室隔网盆栽试验方法,选择两种不同形态的磷肥研究 VA 菌根菌丝对三叶草植株生长和对肥料磷吸收利用的影响。水溶性磷肥(三料过磷酸钙)和难溶性磷肥(磷矿粉)施于边室土壤中,另设不施磷肥的对照,3种施肥处理的植株分别接种和不接种 VA 菌根菌 G.mosseae。结果表明,接种菌根显著增加了植物的生长量,改善了植株的磷素营养状况,根外菌丝对肥料磷的吸收使植株对难溶性磷肥的利用率提高了一倍。 |

| Abstract: |
| In order to investigate the role of VA mycorrhizal hyphae in taking up phosphorus from phosphorus sources of different solubilities,a model experiment was conducted under controlled condition. There were three compartments,in the used pots,one central compartment for root growth,and two out- er ones for hyphae growth.The central compartment was separated from the outer compartments by a ny- lon net with 30 um mesh.Red clover was grown in the central compartment inoculated or uninoculated with VAM fungus G.m... |
