摘要

本研究為探討不同大小尺寸之塑膠栽培管對長形山藥產量及品質的影響，以懷山藥（Dioscorea batatas Decaisne）為材料，採用直徑4、6、8吋之塑膠栽培管及直接種入土中等4種處理，於桃園縣新屋鄉進行試驗，結果塊莖長度及塊莖寬厚比值在處理間之差異極顯著，塊莖寬度在各處理間差異顯著。公頃產量以栽植於直徑8吋塑膠栽培管者最高為22,218公斤；粗蛋白含量以栽植於6吋栽培管者最高為7.05%。

A field trial was conducted in 1993 at Taoyuan District Agricultural Improvement Station to determine the effects of different cultivation with different size of plastic pipe on the yield and quality of long tuber Yam. Plastic pipe used were 4, 6 and 8-inch long in diameter. The experimental design was a randomized with four replication of each treatment. Results indicated that differences in tuber length, width and thickness ratio between the treatments were extremely significant; in the tuber width were significant. The highest yield up to 22,218 kg/ha were produced from the plots with 8-inch plastic pipe. The highest crude protein production of 7.05% were obtained from the plots with 6-inch plastic pipe.
