氣象因子及灌溉對盤固草生產力及乾草品質之影響

Abstract

盤固草(Digitaria decumbens)係一種多年生熱帶牧草，為台灣栽培面積最廣的牧草品種，此牧草於春夏季生長旺盛，而秋冬季乾旱時，其生長呈停滯現象。本試驗研究目的在探討氣象因子及噴灌對盤固草銹病發生、調製乾草品質之影響，以供盤固草栽培管理之參考，期能提高牧草品質。 Pangolagrass (Digitaria decumbens ) is a perennial tropical forage grass with the most widely grown in Taiwan. It grows vigorously in spring and summer and becomes dormant in autumn and winter. Objectives of this experiment were to determine effects of climatic factors and irrigation on occurrence of rust disease, productivity and hay quality of pangolagrass.
