摘要
本文对中国科学院黄淮海平原综合治理封丘试区的四种不同类型潮土作了田间调查、微区试验以及盆裁试验。试验结果一致表明在这四种类型土壤中施用相当于每亩8斤P_2O_3的过磷酸钙最有利于VA菌根真菌的侵染,在适磷条件下接种菌根后可促进菌根菌侵染,缩短其侵染迟缓期,促进了植物对磷的吸收,从而也增加了植物地上和地下部分的生长。
Investigation under field, microplot and pot experiments for the effect of phosphorus fertilization on VA mycorrhizal response were conducted under unsterilized soil conditions, It was indicated that 8 jin P_2O_5/mu (60 kg/hectare) in form of superphosphate was the most favorable P level for VA mycorrhizal infection in 4 types of fluvo-aquic soil in Huang-Huai-Hai Plain of North China. Under such P level both growth and P uptake of plants were promoted by mycorrhizal inoculation while the lag phase of root infection was greatly shortened.
