中文摘要 | 本試驗用我國江蘇原產之 "白大慈姑"作材料於1990年在新竹地區進行 植期與密度試驗、試驗設計採裂區設計、試驗結果摘要於下: 1.以九月十八日種植者產量最高有12,316公斤/公頃,雖與其他二植期間無顯著 差異,其單粒重達22.9克,大粒百分率有41.8,均為最高,且與九月四日、十月 二日種植者間有顯著差異,可知為兼顧產量與大粒百分率時,植期應選九月中旬 較宜。 2.以株距30公分,行距分別為50、60及70公分比較結果,行株距50x30cm,產量 最高達12,415公斤/公頃,而60x300cm產量亦有11,871公斤/公頃,且兩者間無顯著 差異。單粒重與大粒百分率雖以70X30cm最大,60x31cm次之,兩者間無顯著差 異,所以為兼顧產量與大粒百分率,則行株距應採60X30cm較適。 |
英文摘要 | This experiment was conducted in Hsinchu area in 1990 to find out thesuitable planting date and spacing. The "Pai-ta" arrowhead, originated in Kiangsu, China, was used, and splitplot design was applied in this experiment. 1. Arrowhead was planted separately on Sept. 4, Setp. 18, and Oct. 2. The one planted on Sept. 18 gave the highest yield 12,316 Kg/ha, tuber wieght22.9g , and percentage of big tuber 41.8. Of the three, the difference in yield was not significant, yet the difference in tuber weight and percentage of big tuber was significant. Mid-Sept, was the most appropriate time for planting arrowhead.2. The highest yield 12,415 Kg/ha was harvested with spacing of 50 x 30 cm. Next came the yield of 11,811 Kg/ha with spacing 60 x 30 cm. The differ ence was not significant. Both tuber weight and percentage of big tuber were highest when spacing was 70 x 30 cm. But the difference was not sig nificant with those grown of 60 x 30 cm. therefore, spacing of 60 x 30 cm was found the best when both yield and percentage of big tuber were taken into account. |
