| 摘要: | 本實驗使用遠紅外線不織布覆蓋於土瓖表面，探討其對植物生長、土瓖含水率及土壤溫度之影響，結果顯示，甘藷覆蓋遠紅外線不織布者，不論葉月數、塊根數及塊根鮮重皆優於未添加之對照組。就葉月數而嘗，濃度0.8%之實驗組於觀察至第十六周之後，葉片數比對照組多出84.6片。土壤含水率方面於日曬下覆蓋濃度0.8%之實驗組，亦比對照組高出13.42%。而未覆蓋遠紅外線不織布之對照組，其土壤溫度與實驗組比較，亦平均高出l-2℃。
In the study, far infrared ray nonwoven was used to cover on the surface of soil, then how the far infrared ray nonwoven affect plant growth, moisture content and temperature of soil was observed. The result shows the concentration of 0.8% exhibit the best result in rate of growth about leaf number, fresh weight, oven dry weight and number of storage roots of sweet potato. In this experiment, we discovered that leaf number in the concentration of 0.8% was 84.6 more than that of control. After 5 days, the moisture content of experiment group was about 13.42% better than that of control group. |
