摘要

本試驗目的在於探討施用溶磷菌及根瘤菌複合劑、配合氮肥及磷肥不同用量處理等，對春作落花生生長效應之影響。試驗於臺中縣外埔鄉進行，試區土壤屬於紅壤（Red Soil）的陳厝寮系（CCe）。試驗結果顯示，接種溶磷菌及根瘤菌複合劑處理的落花生豆莢產量較不接種處理者增加約5.3%，不施用磷肥0kg P2O5/ha處理的落花生豆莢產量較高於施用磷肥30及60kgP2O5/ha處理者，分別可以增加約9.1及7.2%。施用氮肥40kgN/ha處理與不施氮肥0kgN/ha處理間的落花生豆莢產量差異不顯著。落花生根部的根瘤數在不施氮肥0kgN/ha處理及施用磷肥60kg P2O5/ha處理者較高，落花生根部的根瘤重在不同處理間的差異則不顯著。

The purpose of this experiment was to evaluate the growth effects of spring peanut on the application of phosphorus-solubilizing bacteria and Rhizobia (inoculated or non-inoculate), nitrogen fertilizer (0 and 40kg/ha) and phosphate fertilizer (0, 30 and 60kg/ha). Experiment was conducted on red soil (CCe series) at Waipu Hsiang, Taichung. The field results indicated that the yield of peanut with the inoculation of phosphorus-solubilizing bacteria and Rhizobia was higher than that with the noninoculation by the rate of 5.3%. The yield of peanut with the application of phosphate fertilizer 0 kg P2O5/ha was higher than that with the application of phosphate fertilizer 30 kg P2O5/ha and 60 kg P2O5/ha by the rate of 9.1% and 7.2%, respectively. There was not significantly different on the yield of peanut between the application of nitrogen fertilizer 0 kg N/ha and 40 kg N/ha. The results also showed that the nodule number in the root of peanut were higher on the application of nitrogen fertilizer 0 kg N/ha and phosphate fertilizer 60 kg P2O5/ha, respectively. However, the dry weight of nodule in the root of peanut showed no significantly different among the treatments.
