| 中文摘要 | 行距及株距均以較密為佳,若以一定生長空間而言,則以100~400平方公分左右為最適。密植雖使單株產量及產量構成因素,如單株粒數,每莢種子數,主莖莢數及分枝數等性狀之表現較差,然因株數之增加,致使產量及其構成因素之總表現增加,而獲得增產之效果。 行距及株距對蛋白質含量及油分含量影響小,季節的影響較大,若以生長空間而言,蛋白質含量以200~400平方公分,而油分含量則以600~800平方公分為最適。 各種性狀品種與季節之交感作用達極顯著,乃示各品種在某一季節有其特殊的表現。 |
| 英文摘要 | The effects of spacing on the components of yield and some other characters of soybean were studied at Pingtung Agricultural Improvement Station. Three varieties, three spacing between rows, three spacings within row, and three seasons were used as treatments in this experiment. Planting rates of maximum yields varied greatly with inter- ind intra- row spacings, and seasons. High yields of soybean will be obtained if the spacing is slightly larger than the smallest one, 5×20 cm2. Increasing in planting rate caused the decreasing in the performance of yield components such as number of seeds, pods and branches per plant, while the yields would be increased with the increasing of planting rate. No matter what the row spacing was, the optimum area per plant for obtaining maximum yield was 100-400 cm2. Both protein and oil contents were very little affected by inter-row spacing and intra-row spacing. For protein, the optimum area per plant was 200-400 cm2; for oil, 600-800 cm2. Based on the results of this experiment, the author recommends three different spacings for high plant type Palmetto, intermediate plant type Taita-kaohsiung No. 5, and dwarf plant type Shi-shih, in spring, summer and autumn seasons respectively. They are shown in table 5. |
