| 摘 要： | 非灭菌条件下在田间小区研究了潮土接种ＶＡ菌根真菌（Ｇｌｏｍｕｓ ｓｐ）玉米的影响。试验表明，在每公顷６０ｋｇＰ２Ｏ５的条件下接种ＶＡ菌根，植株含磷量，含氮量，生长状况、产量及品质均高于未接种的植株。石灰性土壤由于高ｐＨ值的缘故，使得磷矿粉＋ＶＡＭ处理的效果比ＶＡＭ＋过磷酸钙的处理稍差，无外加磷源公接种ＶＡ菌根的处理，其效果接近于施磷肥的对照。

| Abstract: | The effect of VAM(VA mycorrhiza;Glomus sp)on maize was studied in the field experiment in unsterilized fluvo-aquic soil.The experiment results showed that inoculating with VA mycorrhiza and applied 60kg P2O5/ ha was benificial to P and N cotents of plant,promoting plant growth and improving output and quality of maize.Owing to the high pH value of calcareous soil,the effect of VAM in the treatment of ground phosphate rock was not as good as the treatment of calcium superphosphate.The growth vigour and yield of maize in treatment of inoculating with VAM but no additional P was similar to check plot. |
