中文摘要 | 本試驗目的在探討盤固草(A254)不同收刈頻度對於盤固草生長及士壤硬度的影響。由本試驗結果顯示;一年收刈三次有最高的牧草產量;收刈四次者,其粗蛋白的含量較高,而以收刈二次者,其酸、中洗纖維較高,但粗蛋白與中洗纖維含量的差異均不顯著。 不同收刈次數對於土壤硬度的影響,隨著年收刈次數之增加,土壤有變硬之趨勢,而且土壤硬度隨著牧草生長牛限的增加而增加。不同收刈次數對盤固草收穫與調製所花費之農機費用,每生產一公斤乾草所花費之農機成本,隨收刈次教之增加,其成本亦隨之提高,且農機成本有逐年增加的趨勢。 |
英文摘要 | The purpose of this study was to investigate the effect of different cutting frequencies on the growth of pangolagrass (Digitaria decumbens) and soil hardness. It showed that pangolarass with 3 cuts per year produced the highest groage yield. It had high crude protein content with 4 cuts/year while it had higher ADF and NDF contents with 2 cuts per year than the other treatments. When the cutting frequency was increased, the soil became harder. Soil hardness was also increased when pangolagrass growth was advanced. The cost for hay making of pangolagress was increased when the harvest frequency and the growth years were increased. |
