中文摘要 | (一)黃麻性喜高溫多濕,生長期間須有充足水分,以利發育。臺灣之年雨量雖高,惟分布甚不理想,且多豪雨,是以對黃麻之生長,難收適時供水之效。 (二)黃麻生長期灌溉效果之研究,計分"灌溉時期"暨"增施肥料灌溉"兩部份。一則探知黃麻生長期中最有效之灌溉時期;再則探求在充分灌溉條件下,氮鉀肥料之有效增施量。 (三)本試驗研究,自52年起至54年止,連續舉辦3年。經試驗結果,確知本省黃麻生長期間,必須有適當之灌溉;至於增施肥料之處理,因受肥料報酬漸減律之支配,並無顯著之效果。 (四)灌溉時期處理間,初期及後期灌溉之效果不大;全期灌溉效果最好,每公頃精洗麻高達2514.5公斤,較對照處理不灌溉者增產22.7%;中期灌溉次之,每公頃精洗麻產量達2475.5公斤,增產20.8%。全期灌溉與中期二灌溉處理間之產量差異不大,故以後者較為經濟實用。 (五)供試黃麻,年度間之產量差異甚大,此因各年氣候及降雨情形各異所致。其中以53年雨水分佈較勻,黃麻生長最好,處理間之產量差異極顯明。 |
英文摘要 | The jute plant grows best in a moist hot climate. Especially it requires plenty of water during its vegetative growing stage. In Taiwan, the annual precipitation is roughly 1,500-2,000 m.m. in average, but it is not distributed uniformly. Most amount of rainfall is from June to September so that the effective rainfall is quite slight and suitable irrigation is necessary for jute cultivation. This experiment was carried out at Chai-I Substation of Tainan Fiber Crops Experiment Station, TARI from 1963-1965. The results are described briefly as follows: (1) Experiment on irrigation during different growing stages: The average yield of retted fiber from irrigation in whole growing period is 2,514.5 kg/ha and that in the middle growing stage 30-60 days after germination is 2,475.5 kg/ha. Their yields are increased over that from no irrigation by 22.7% and 20.8% respectively. There is almost no significant difference between treatments from irrigation in whole growing period and in middle growing stage. It is necessary to irrigate in middle growing stage of jute in order to increase the yield of retted fiber effectively. (2) Experiment on the effect of supplying additional amount of N and K2O and irrigation: Irrigaiotn in growing stage is very important for jute cultivation, no matter what amount of fertilizers is supplied. Under "the law of diminishing return", there is almost no significant differnce of fiber yield among different additional levels of N and K2O. Owing to the variation of rainfall among years during growing stage of jute, the effect of irrigation is different significantly among years. For example, there is a significant difference among different treatments of irrigation in 1964 for the distribution of rainfall is quite uniform that year. |
