大豆高雄選10 號品種在臺中地區栽培產量之探討

Abstract

本研究以大豆高雄選10 號為試驗材料，探討大甲 (Dajia)、大安 (Daan)、清水 (Cingshuei)、梧棲 (Wuci)、龍井 (Longjing) 及大肚 (Dadu) 等6 地區晚植產量試驗。試驗結果顯示，高雄選10 號在示範區之生育期約在97–107 天之間，且其植株之農藝性狀皆達顯著性差異，其中示範區每公頃平均產量分布於1,139.6–3,882.9 公斤。部分田間觀察莖潛蠅危害極為嚴重，其株高、單株分枝數、單株節數、單株莢數及百粒重等性狀皆較健康之植株表現較差。整體而言，晚植地區之植株生育期有較短趨勢且於幼苗期階段易發生莖潛蠅。 The purpose of this experiment is to evaluate late planting on growth characters and their yield of soybean variety KSS10 in the ratoon rice field of Taichung in 2015. Experiment plots included Dajia, Da-an, Cingshuei, Wuci, Longjing and Dadu. The results showed that the growth period of KSS10 was about 94 to 107 days. The agronomic characters of yield components of KSS10 were significant different and the average yield were 1,139.6–3,882.9 kg/ha in experiment plots. Some of experiment plots were attacked by Soybean stem miner (Melanagromyza sojae.), Their characters were poor in plant heigh, branch number per plant, node number on main stem, pod number per plant and 100-grain weight than non-attacked. Overall, the plant growth period of the late planting plots was shorter and severely damaged by Melanagromyza sojae.
