摘要

為提高本省秋冬裡作蕎麥單位面積產量，於78年秋裡作在彰化縣大村鄉本場實驗農場，利用2個大粒品種、1個中粒及1個小粒品種進行播種期、播種量及栽培密度試驗，獲得如下結論：蕎麥之適當播種期宜由慣行之11月上旬提早至10月下旬，此為提高蕎麥產量最有效之方法。其適當播種量，大粒型品種為每公頃90 kg，中粒型品種為70 kg，大粒型品種中以宮崎大粒之產量表現較佳。無論何種粒型之蕎麥品種均宜採密植栽培，其行株距大粒型品種為30×10 cm，中粒及小粒型品種為30×10 cm、35×10 cm或撒播。

Two large grain varieties, Miyazaki Ootsubu and Shinshu Oosobo, one medium grain variety, Hitachi Akisoba, and one small grain variety, Toyota No.1 were used to study the influences of sowing date, seeding rate, and plant spcing on the agronomic and yield characteristics of buckwheat grown as a fall crop in Changhua area of Taiwan. Experimental results indicated that judging by the yield performance, the proper sowing time for both large and medium grain varieties was around October 25, which was 20 days earlier than the conventional sowing time employed by the farmers. The most suitable seeding rate for obtaining the highest grain yield was different for varieties differing in grain size. The seeding rate of 90 kg/ha was recommended for large grain varieties, and 70 kg/ha for medium grain variety. On the other hand, the high planting density with spacing of 30 x 10 cm was best for the two large grain varieties, while the spacings of 30 x 10 cm and 35 x 10 cm, or the method of broadcasting were best suitable for medium and small grain varieties.
