樹豆及烏豆品種(系)適應性試驗

Abstract

1.94 年4 月8 日播種者以S-40 的茶褐色樹豆品系單株種子重最高，平均達到351 公克，比T.H-1（ck）增加8％，成熟豆莢數高達966 莢佔總莢數97.87％，比T.H-1（ck）的704 莢增加35.60％，頗適合在4～5 月播種。 2.94 年7 月8 日播種者以S-1-3 的樹豆白色品系單株種子重最高，平均達到353 公克，比T.H-1（ck）增加25.62％，成熟豆莢數也達到756 莢，比T.H-1（ck）的550 莢增加37.22％；成熟豆莢率S-1-3 及T.H-1（ck）均高達97.17％， S-1-3 品系極適合在7 月播種；至於T.H-1（ck）單株種子產量也達到281～325 公克，並不遜其他品系，在4～5 月及7 月均可播種。 3.95 年春作臺東試區以TS80-106B 品系的鮮莖葉重為11,900 公斤/公頃、乾莖葉重為2,450公斤/公頃、烏豆仔粒產量是2,220 公斤/公頃；太麻里鄉金崙試區則以臺東烏豆的鮮莖葉重為14,750 公斤/公頃、乾莖葉重為3,250 公斤/公頃、烏豆仔粒產量也達到2,033 公斤/公頃，比臺南5 號增20.15%。 4.95 年秋作調查三處試驗結果：以屏東烏豆品系仔粒產量最高，在臺東試區烏豆仔粒產量達到2,790 公斤/公頃，比臺南5 號（ck）2,450 公斤/公頃增加13.87﹪；太麻里鄉金崙試區為2,854 公斤/公頃，比臺南5 號（ck）1,854 公斤公頃增加57.93﹪，並且達到差異極顯著平準；海端鄉加拿試區產量是2,270 公斤/公頃，比臺南5 號1,979 公斤/公頃增加14.70﹪。 5.屏東烏豆在臺東地區頗適合秋作，平均可採收烏豆種子2,270～2,854 公斤/公頃，值得推廣。 This experiment was conducted to evaluate the effect of different sowing date on pigeon pea yield. The line of pigeon pea, S-40, had the highest seed yield of single plant - 351 g on April 8, 2005 in Taitung area. On July 8, 2005, The line, S-1-3 had single plant seed yield- 353 g which was 25.6 % higher than check, T.H-1. In Taitung area, The line, S-1-3, is sown to have the better seed yield in July. The lines, S-40 and T.H.-1 can adapt on April to May and july. Screening of black soybean accessions for green manure and health food in Taitung. The result indicated that the line, TS80-106B, had the highest fresh plant weight - 11,900 kg/ha and seed yield - 2,220 kg/ha in Taitung area in spring, 2006. At Chin-Lun site, the line, Taitung-black soybean, had the highest fresh plant weight - 14,750 kg/ha and seed yield - 2,033 kg/ha which was 20.15 % higher in seed yield than Tainan No. 5 in spring, 2006. Pintung-black soybean had the highest seed weight in autumn, 2006, it were 2,790, 2,854 and 2,270kg/ha at Taitung, Chin-Lun and Chia-na site, respectively. Pingtung-black soybean will be recommened to cultivae in Taitung area for increasing the fertility on the paddy.
