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Glomussp.)对玉米Maize)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,无外加磷源仅接种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 fieldexperiment in unsterilized fluvo一aquic soil. The experiment results showed that inoculatingwith 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 pHvalue of calcareous soil, the effect of VAM in the treatment of ground phosphate rock wasnot as good as the treatment of calcium superphosphate. The growth vigour and yield ofmaize in treatment of inoculating with VAM but no additional P was similar to check plot.

Key words: Vesicular-arbuscular-mycorrhiza, Maize, P and N nutrition
