中文摘要 | 本研究以大豆台南4號綠肥作物為對象,從現場及實驗室分別了解其根部與莖部生長之情形。實驗結果顯示大豆台南4號綠肥三個月期間生長高度約達69公分左右,在第30天平均生長高度約為30.7公分,在第60天的生長高度約為50.7公分,到了第90天到達約69公分左右。而主根生長深度相對約為18公分左右,第30天平均生長深度約為8公分左右,第60天約達11.4公分,到了第90天平均總長度到達地下約17.6公分左右。另外主莖與其根部生長變化呈現對數之關係y = 67.8Ln(x) - 111.78 ,式中x為主根生長深度, y為莖部生長高度(公分),主根生長10公分時主莖相對高度約為44公分,而主根生長到17公分時主莖約為70公分左右。於實驗室砂箱面積2400cm^2,深度40公分下獲得其生長之所需水量,生長40公分高大約需670mm水量。 |
英文摘要 | This research regard the crops of green manure at Tainan soybean No.4 as the object to understand the situation of its root and stem growth respectively from the scene and laboratories. From the experiment result shows that the total height amounts to about 69 cm at about three months, in the 30 days grow height about 30.7 cm, in the 60 growth highly about 50.7 cm and go to the 90 days arrive about 69 cm . Respectively the total length of main root is about 18 cm in the 90 days, in the 30 days the average height grow to about 8 cm, in the 60 amount to about 11.4 cm . Besides main stem and its root growth varieties present the relation of the logarithms y =67.8 Ln( x) - 111.78 which x( cm) is the height for the main root, the y ( cm)is the height for the main stem , opposite height in main stem for main root to grow 17 cm is about 70 cm。In laboratory, an area 2400 cm^2 and the depth is 40 cm of sand box, a water need is about 670mm when the heigh of main stem to 40cm. |
