| 中文摘要 | 為探究沙烏地阿拉伯卡新省典型的王子農場盆地栽培雙期水稻之可行 性,於1978年間春作,用三個長粒型秈稻品種,一為當種Amberbook,另二種 由台灣引進之NTU 302-2-2及Sipi 201602,自1月30日起至2月26日止,每隔 10天播種及插秧一次,計4處理;在夏作用Amberbook及NTU兩品種,自5 月30日至7月30日止,每隔15天種植一次計5處理。重複4次,裂區設計。 土壤為沙質粘土。其初步試驗結果如下: 春作: 1.收量最高之時期處理,NTU為第3處理高達10.32 t/ha,次為Sipi及Amberbook 之第2處理產量分別為8.43及5.00 t/ha。 2.播種最適宜時期,NTU在2月16日或中旬,Sipi及Amberbook均在2月6日 或上旬,在播種後35∼40天插秧。 3.過早種植,在秧田及插秧後會發生嚴重之冷害,但過遲栽培會減少分蘗及穗 數,導致減產。 夏作: 1.產量最高之時期處理均為種植最早者,NTU達7.25 t/ha,Amberbook為4.88 t/ha。 2.夏作最適宜之播種時期,均顯示須在6月上旬之前,以20天苗插秧為宜。 3.種植較遲時在10月間會遭嚴重的冷害,會導致嚴重的減產,或因抽穗不結實, 甚至不會抽穗。 總之,在沙國卡新省之盆地,要在一年當中,同一塊土地上要種植雙期水稻, 因受氣候之限制,是根本不可行者。但如在適期栽培高產NTU品種產量極高, 且很安定。當地Amberbook品種宜在晚春至初夏種植,NTU即在春夏種植為宜。 |
| 英文摘要 | In 1978, the first trial of double croppings of rice in Saudi Arabia was made with three long-grain indica rice varieties, one being local Amberbook and the other two from Taiwan, NTU and Sipi (used in the spring only). The varieties were tested with 4 dates of sowing/transplanting, starting from January 30 through February 26 at 10-day intervals, as the spring crop, and with 5 dates of sowing/transplanting, starting from May 30 through July 30 at 15-day intervals as the summer crop, in a sandy clay soil of Prince Naif's farm in Gassim basin of Saudi Arabia. From the spring experiment, it was found that yield was the highest in February 2 seeding, reaching 5.00 t/ha in Amberbook and 8.43 t/ha in Sipi. However, the variety NTU gave the highest yield of 10.32 t/ha when seeded on February 16. Too early planting suffered from serious cold damage in the seed-bed and in the early stage of growth after transplanting. Late planting showed decline in tiller number and grain yield. 1. The summer experiment showed that the eariest planting gave the highest yield, 4.88 t/ha in Amberbook and 7.25 t/ha in NTU. 2. The optimum seeding time was before early June, and about 20-day old seedlings were transplanted. 3. Late plantings suffered from cold injury prevailing after October. Double rice croppings on the same land in Gassim is impossible due to the constraint of weather. Amberbook is suitable for late spring and/or early summer cultivation, while NTU for spring cultivation. |
