中文摘要 | 本研究旨在探討於酸性紅壤接種菌根菌(Vesicular-arbuscularmycorrhizae,VAM)及溶磷菌(Phospho-rus-solubilizingbacteria),在不同磷肥施用量下,對磷肥有效性和洋香瓜生長之影響。試驗結果顯示,洋香瓜苗定植30天後,接種區的植株單一子蔓長度,比未接種區長4-10公分,可知其對洋香瓜初期營養生長有促進效果。在產量方面,菌根菌及溶磷菌一起接種比個別接種佳,施用P2O5 90kg/ha下,同時接種溶磷菌及菌根菌之處理可比未接種區增產12%,差異達5%顯著水準,且與施用P2O5 180kg/ha試區相較,產量差異並不明顯。在果實品質方面,磷肥施量越高則果實越重,在施用磷酐0及60kg/ha試區,接種微生物可明顯增加果實大小及甜度,平均單果重較未接種區分別增加80及70公克,果實可溶性固形物含量(Soluble solids content)則可分別提高0.7及1.0°Brix,與施P2O5 80kg/ha試區相比,毫不遜色,而對品質增進效果隨磷肥之減施而增大。可見接種溶磷菌及菌根菌在低磷肥區對洋香瓜生育確有正面之效果,可促進產量及品質,但在施高化學磷肥田區則效用不顯著。 |
英文摘要 | A field experiment was conducted to study the effect of inoculation with vesicular-arbucular mycorrhiza(VAM), Glomus clarum, and phosphorus-solubilizing bacteria(PSB) on the muskmel-on growth in acid red soil. Data showed that the single vine length of muskmelon inoculated with V AM and PSB was longer than noninoculated controls at 30 days after transplanting. The applicaton of P2O5 at rate of 90 kg/ha with inoculation of V AM and PSB resulted in an increase in fruit yield by 12% as compared with that application of the phosphate alone, however, it was not significantly different as compared with those plots applicated at rate of 180 kg/ha. The fruit weight and soluble solids content were increased by 80, 70 g/per fresh fruit and 1.0, 0.7°Brix with inoculation at the application rate of 0 and 60 kg/ha P2O5, respectively. This study suggested that the muskmelon yield increases can be obtained by inoculation with V AM and PSB in acid red soil under the conditions of low phosphate application. |
