説明
The experiments were conducted from 1966 to 1968 in peanut fields of volcanic ash soil at Yachimata, Chiba Prefecture, where the peanut had been cultivated successively for more than 3 years. Various amendments-manures of peanut plant, rice straw, or sawdust, iron sludge, and lime-added to soil had no effect upon the populations of trapping fungi and of Meloidogyne hapla in fields at 3 sections, Sumino, Ozeki, and Sasabiki, where the amendment treatments were made for 1, 2, or 3 years, respectively. Positive correlations with high coefficient were observed between population densities of the nematode trapping fungi and of the root-knot indices at Ozeki in June and October, 1967, and June, 1968, and at Sumino in October, 1967. Similar results were obtained in June 14 fields at different localities which excluded low land field, field of low soil pH value, and deeply plowed field. However, negative correlations with high coefficient were observed, on the contrary, at these fields in October. Thus, the significant role of the trapping fungi in relation to the checking of the nematode infestations was observed in many instances in these fields, when the relationships between the population densities of the fungi and that of the nematodes were analyzed in consideration of seasonal changes in these organisms. No correlations were observed between densities of the nematode trapping fungi or the root-knot indices and conditions of field soils such as the solid phase, the liquid phase, or pH.
