綠肥用烏豆品種(系)適應性試驗

Abstract

94 年春作或秋作鮮莖葉產量均以TS80-106B 的品種最高，達到16,334~17,200 公斤/公頃，比臺南5 號（CK）增加40.51%及145.71%，經調製後的乾莖葉重平均是3,600~4,417公斤/公頃，比臺南5 號（CK）2,400~3,438 公斤/公頃增加50~28.48%；其次是恆春烏豆、臺東烏豆、屏東烏豆等三個品種（系），其鮮莖葉產量在春作平均達到12,666~14,667 公斤/公頃，比臺南5 號（CK）增加80.94~109.53%，乾莖葉重春作平均是3,334 公斤/公頃，比臺南5 號（CK）2,400 公斤/公頃增加38.92%，秋作或因日照長及溫度高的影響，烏豆乾莖葉重平均較高，三個品種達到4,063~4,583 公斤/公頃，比臺南5 號（CK）3,438 公斤/公頃增加18.18~33.30%，值得繼續探討，以確定烏豆品種間產量的穩定性。 10 selected black soybeans were conducted with Tainan No. 5 as the check. The results were showed that the line, TS80-106B was the highest fresh weight about 16,334 - 17,220 kg/ha, it was higher in fresh weight than the check, Tainan No. 5 by 145.7% in spring crop and 40.5% in fall crop of 2005, respectively. TS80-106B was the best dry weight about 3,600-4,417kg/ha, and was 50.0 -28.5% higher in dry weight than the check. Another three varieties - Hengchun black soybean, Taitung black soybean and Pintung black soybean were 80.9 - 109.5% higher in fresh weight than the check in spring crop. In spring crop, the average dry weight of these lines was 3,334kg/ha, and was 38.9% higher than Tainan No. 5. In fall crop, the average dry weight of these lines was 4,063-4,583 kg/ha, and were 18.2-33.3 % higher than Tainan No. 5.
