| 中文摘要 | 以本場新育成的品種臺東30號為材料,探討不同栽培密度與移植苗數對其生育及產量的影響。試驗結果顯示,臺東30號經過適度的調整栽培密度時,其穗重、稔實率及千粒重有增加的現象,但過於密植反而會造成千粒重及穗重的減少;增產效果則以二期作較為明顯,比慣行法分別增加4%及5%左右,公頃產量分別為6,971公斤與6,999公斤。而不同移植苗數處理對水稻農藝性狀的改變亦不同,單本植處理其每株穗數最少,而其它處理的穗數隨著苗數的增加而增加,但穗重、一穗穎花數則隨著插秧苗數的增加而減少;除了91年2期作每叢插13株的產量偏低外,其它處理的千粒重及產量並沒有顯著差異。 |
| 英文摘要 | In order to study the different cultural density and transplant seedlings on the yield component of Taitung 30, two experiments were investigated on (1) the cultural density were separated from 30×15cm, 30×10cm, 15×15cm; (2) the transplant seedlings were separated from 1、5、9、13 seedlings. Results indicated that the panicle weight, fertility and weight of 1,000 grain were increased on the treatment 30×10cm, but the weight of panicle and weight of 1,000 grain were decreased on the 15×15cm. In view of cultural density on the yield of Taitung 30, the best density of 15×15cm had higher yields about 6,999 kg/ha on the second crop, and had no significant difference on the first crop among all the densities. The number of panicles were increased when the fields had transplanted a few seedlings; otherwise, the weight of panicle and grain number were decreased. About the weight of 1,000 grain and yield among all the treatments of different seedling were not significantly. |
