中文摘要 | 為探討覆蓋材料對長形山藥栽培之影響,於民國82至84年間以不同覆蓋材料進行試驗。各覆蓋材料對長形山藥之萌芽率並無顯著影響。長形山藥塊莖的產量及品質以稻草覆蓋最好,有較佳的薯長及薯徑,且分歧數最少,塊莖的商品價值高。銀黑色塑膠布覆蓋下的產量與其它處理差異不大,但因塊莖分歧數增加而降低商品產量;因黑色不織布覆蓋的塊莖分歧數較銀黑色塑膠布覆蓋少,故84年試驗之商品產量較銀黑色塑膠布覆蓋高出3.7 M.T./ha。白色不織布不具防除雜草的效果,產量最低,不適用於長形山藥之栽培。對照無覆蓋處理對產量雖無顯著影響,但增加除草之人工成本。綜合三年試驗結果,以稻草覆蓋處理生產之長形山藥產量及品質最佳,在稻草不易取得時,可用黑色不織布做為畦面覆蓋材料。 |
英文摘要 | The study the effects of different mulching materials on yield and quality of long-shaped yam, field experiments were conducted in 1993, 1994 and 1995. The mulching treatments were rice straw, sliver black PE film, black and white non-woven fabric mulch, and non-mulching culture as the check. The results indicated there were no significant difference among different mulching materials for tuber sprouting rate. Mulching with straw had the highest yield and quality of tuber due to the longer length, larger diameter and less branch number of tuber, the marketable value of the straw treatment was higher than other treatments. Yield of mulching with silver black PE film was not significantly less than other treatments, but the marketable yield was lower due to the increasing tuber branches. Because of the less branch number of tuber, the marketable yield of mulching with black non-woven fabric was 3.7 M.T./ha greater than mulching with sliver black PE film in 1995. Mulching with white non-woven fabric had no effects on weeded control which due to the lowest yield, so it is not recommended to the culture of long-shaped yam. Because of the high labor cost for weed control, the non-mulching treatment was not recommended. According to these results, straw and black non-woven fabric were recommended as mulching materials for long-shaped yam cultivation. |
