中文摘要 | 本試驗目的在探討不同省工栽培方法對水稻產量與米質之影響。經82、83年兩年試驗結果顯示:一期作稻穀產量均以直播區較佳,分別為5161及5223kg/ha,較對照機插區增產5.5%及3.7%。第二期作則以機插區產量較高,各為3814及2769kg/ha,較直播後再生區與機插後再生區增產8.7-14.6%及15.4-16.5%。稻米碾米品質及米質檢定則以兩期作均機插最佳,米粒外觀及米質檢定亦較優良。稻穀全年淨收益以第一期作直播後第二期作再生較佳,每公頃收益82年為73,627元,83年為59,640元,較兩期作機插51,638元及38,505元,分別增加收益42.6%及54.9%。 |
英文摘要 | In order to evaluate the effects of labor-saving cultivation on the yield and quality of rice in I-Land area, the cultivar Taikun No.1 was used for experiment from 1st crop 1993 to 2nd crop 1994, with direct seeding followed by ratoon, machinery transplanting followed by ratoon and machinery transplanting in both crops (CK). The results showed that the direct seeding in 1st crop produced yield (5161 and 5223Kg/ha respectively) higher than the CK (4894、5038Kg/ha) by 5.5% and 3.7%. For 2nd crop, the machinery transplanting got higher yield (3814、2769Kg/ha) than direct seeding- Ratoon(3483 and 2366Kg/ha respectively) and machinery transplanting-Ratoon(3228 and 2312Kg/ha respectively), those are reduced by 8.7-14.6% and 15.4-16.5, respectively than the CK in both years. On the other hand, machinery transplanting in both crops showed better milling quality, chemical properties and grain appearance than other treatments. The labor-saving caltivation method( direct seeding followed by ratoon) got higher profit( 59,640-73,627 NT$/ha) than the CK (machinery transplanting in both crops) (51,580-51,638 NT$/ha) by 54.9 to42.6% in both years. |
