不同環境對山葵生長與產量之影響 Taiwan Agricultural Research Institute
胡敏夫; 邱善美; 劉新裕; M.F. Hu; S.M. Chiu; S. Y. Liu.
[[abstract]]為了探討山葵之適應性與新地區栽培對墨入病(Phoma wasabia YOKOGI )蔓延之遏阻程度,乃選定本省中部海拔1200M 高冷地信義與溪頭兩地方,分別採用人工架設黑色塑膠網與不同自然環境試作發現:1.信義試區:所種植山葵之生育,以架設75~80%遮蔭網較佳,種植後90 天之平均株高為16.9cm,平均葉數為17.8 葉。經測定其實際遮蔭率恰為70%,適合山葵之生長,惟其後因栽培環境溫度偏高、濕度偏低,並發生白誘病,而於成熟前乾枯死亡,因之信義地區可能較不適合種植山葵。2. 溪頭試區:發現種植於空曠地山葵之生育較衫樹下良好,平均公頃根莖量為17,125kg,葉柄量為26,75Dkg ,鬚根量為5,625kg。平均公頃估計收入可達3,596,250 元,比杉樹下種植區多收1,396,250 元。於溪頭試區就氣溫因子加以調查,發現溪頭試作區栽培環境可媲美阿里山產區,也比日本伊豆產區優異,且產量高於日本伊豆地區。墨入病罹病率調查結果,空曠地區者達100%,根莖平均罹病長度為5.2cm,杉樹下試區罹病率為80%,根莖平均罹病長度4.2cm,經研判其因可能為種苗帶菌所引起。 In order to find out some new places suitable for the growth of wasabia and to minimize the severe damage caused by phoma blight disease, experiments were conducted at Hsinyi and Hsitou areas, both are 1200m above sea level and in Nantou county.

邱善美; 韓青梅; 莊周瑞; S.M. Chiu; C.M. Han; J.R. Juang.
[[abstract]]本試驗之目的在探討亞麻植期對朔果(種子)發育及種子成熟度對油分含量之影饗。結果顯示,亞麻朔果初期(開花後第10 天)的發育與增大受植期之影響頗大,早植(10 月20 日播)較晚植者(11 月17 日播)初期之發育為緩慢,其增大最快的時期發生於開花後的20 天,爾後增大甚少,或停止增大。晚植者初期發育較快且可持續的增大。 不論品種為何,朔果百粒重自開花後均持續的增加,但植期間略有不同,早植對朔果百粒重較為有利。一個朔果之種子數於開花後第20 天已大致固定,種子粒數以晚植者多於早植者,臺農選2 號又較CI 2288 及2540 為多。種子百粒重增加之趨勢,植期間表現不一,初期的增加以早植優於晚植,而後期(開花後30 天)概以晚植優於早植。 種子油分含量隨品種、植期及種子成熟度而異,臺農選2 號於開花後20 天(10 月20 日播)及30 天(11月17 日播)油分含量達最高,各別為40.4%及41.4%,嗣後即開始下降。CI 2288 及2540 在早植之環境下,油分含量有持續增加的趨勢,但晚植者於開花後30 天油分含量達最高。對碘價之影響植期間遠大於品種間,開花後30 天早植之碘價在200-210 之間而晚植者則在170-180 之間。 Three flax cultivars, TNS 2, CI-2288 and CI-2540, were planted on two different dates (Oct. 20 and Nov. 17) in order to study the effect of sowing date on the capsule (seed) development and crude oil content at various stages of...

期作與秈稉二型水稻品種之生育相研究 Taiwan Agricultural Research Institute
邱善美; S.M. Chiu.
[[abstract]]本試驗在探討瞭解稻生產過程中影響高產的生理過程,形態特徵,以明瞭不同期作對秈稉二型水稻品種產量的高低是否由於品種的本質或其也因素或產量組成成份,以供今後改良二期作品種選拔之參考,玆將試驗結果摘要如下: 不同類型品種間期作對株高伸長的過程有極大的差異,半矮性秈稻品種或植株較矮的稉稻品種(如Todorokiwase)一期作株高的伸長速度,以生育前期大於生育後期,高稈的稉稻品種則生育後期大於生育前期,但以抽穗期達最高峰。二期作,二型品種株高的伸長速度,均以生育前期大於生育後期,但所受環境的影譽稉稻大於秈稻。 在第一期作之環境下,品種間初期分蘗數的增加影響甚微,移植後5~6週間為分蘗最旺盛時期,分蘗期約可延續一個月之久。二期作分蘗的增加趨勢與第一期作不相同,分蘗期短促為其一大特色但穗數仍以秈稻品種較梗稻品種多。 就供試6個品種言,一期作之稈高均高於第二期作,穗數亦以第一期作較第二期作多,但稉稻較秈稻差異大,(如高雄64號,一二期作差異27%為最大,次為Todorokiwase 12.5%,新竹矮腳尖4.1%,而嘉農秈11號無差異)。一穗粒數一二期作之差異以Todorokiwase為最大(24.8%),次為臺農38號,高雄34號,新竹矮腳尖,分別為12.4, 10.5, 8.4%,以嘉農仙11號之3.2%最低。千粒重以新竹矮腳尖之差異最大(15.2%),嘉農仙11號較少(4.7%)。 一二期作單位面積稻殼產量的差異,以Todorokiwase最大(減產30%)臺農38號及高雄64號次之(分別減產21.3及21.5%)新竹矮腳尖及嘉農秈11號居三(分別減產17.4及15.7%)以花草18號減產8.3為最少。 Plant type and growth pattern are known to...

氮肥施用方式對藺草產量與品質之影響 Taiwan Agricultural Research Institute
胡敏夫; 邱善美; 劉新裕; M.F. Hu; S.M. Chiu; S.Y. Liu.
[[abstract]]於藺草整刈前之生育早期與整刈後之生育中、後期,每公頃各施用氮量(A)147kg及441kg,(B)84kg及346kg, (C)84kg及252kg,(D)84kg及301kg(其中49kg為大豆粕所含有)等4種施肥方式,分多次施用,以探討對藺草產量與品質之影響。發現慣行施肥方式A處理,於莖長、每叢莖數、乾草產量及有效莖率,分別為127.4cm、330支、18,400kg及70%,均有較佳表現,且比其他處理高,但經顯著性測定後,除有效莖率外,其餘性狀並未呈顯著差異,尤其與B處理相較差異甚微。實際收益比較,多施氮肥之A處理雖收益較高,惟其初期生育並未因於早期每公頃多施用63kg氮肥而比其他處理良好,且整刈後多施氮肥情況下,有紋枯病發生現象。因此,藺草氮肥施用方式,似應採用B處理之施用方式,於整刈前及整刈後,每公頃各施用氮肥84kg及346kg較適當。整刈後施用大豆粕之方式,於本試驗中無增產效應,似不宜採行。 The influences of amount and frequency of N fertilization on the yield quality of mat rush were studied with the aim at evaluating the adequacy of heavy application of N fertilizer in coventional cultural practice. The amount of N applied per hectare before and after tip-cutting for the four treatments were, respectively, 147 and 441 kg...

水稻抗稻熱病多品系品種及混合品種之抗病性、生產力及品質之研究 Taiwan Agricultural Research Institute
邱善美; 鄧耀宗; S.M. Chiu; Y.C. Teng.
[[abstract]]本試驗主要目的在探討水稻多品系品種及混台品種對稻熱病的抵抗性、生產力及稻米品質。經在本省北、中、南部稻熱病猖獗地區試驗結果顯示:混合品種或多品系品種之抗病性均較對照品種強,而混台品種之抗病性又較多品系品種強,但以三處所(臺北、臺中、嘉義)所選出的抗病系統組成的較二處所(臺北、臺中)所組成的抗病。多品系品種則以抗六種不同生理小種所組成的品種較抗五種不同生理小種所組成者抗病。 稻穀產量,第一期作,坪林(臺北縣)試區以品種M-8-1產量最高,較對照品種增產50%,其他各供試品種之增產幅度為45%~7.3%之間。白河(臺南縣)試區稻熱病較他二試區嚴重,種植混合品種或多品系品種之效益更為明顯,如品種C-8-1、M-8-1、M-8-2較對照品種約增收三倍左右。萬巒(屏東)試區,供試品種之增產幅度為32%~2.5%為之間(除品種C-5-2)。第二期作,除坪林發生病害顯示其效益外,其他二試區未發生葉稻熱病為害,混合品種之效益未能顯示。 經測定米粒品質後發現:米粒品質之優劣與品種抗病性有極大關係,尤以米粒的透明度、腹白、心白最為明顯,如以此三種性狀來表示米質的良否,混合品種或多品系品種較對照品種有較優的表現。 The present study was aimed to compare the blast resistance, productivity and grain quality between the multiline and composite varieties of rice.

水稻抗稻熱病混合品種之抗病性及生產力研究 Taiwan Agricultural Research Institute
邱善美; 鄧耀宗; S.M. Chiu; Y.C. Teng.
[[abstract]]1. 抗病品系之混合品種較感病品種確有控制稻熱病蔓延之效。臺南5號或嘉南8號均為感病品種,其第一期作葉稻熱病之罹病率分別為35.7%及85.3%。第二期作為50.2%及89.2%。混合品種之罹病率,第一期作以5-1、9-1及31-2最低,僅有1.0%之罹病率,最高者為40-2,但亦僅有5.1%。第二期作以3-1及5-1之罹病率最低(罹病率1.5%),以7-1最高(罹病率10.5%)。至於穗稻熱病之罹病率亦很明顯的可以看出混合品種低於對照品種。 2. 在發病地區混合品種與對照品種的稻穀產量,一、二期作均顯示品種間有極顯著的差異存在。第一期以33-2產量最高,次為41-2、40-2、31-2、3-1等品種。第二期作因發病程度較第一期為嚴重,混合品種單位面積產量有更突出的表現,如41-2產量較對照品種約增收一倍以上,其他各混合品種亦增收40~70%之間。由此可認定在稻熱病發生地區種植混合品種有穩定產量之功效。 3. 一般環境下,種植混合品種之結果,顯示在臺北及嘉義品種間產量差異不顯著。屏東第一期作以嘉南8號產量最高,41-2次之,但差異並不顯著。第二期作品種間差異極顯著,以3-1及7-1產量最高,分別較對照品種增產30%及10%,其他品種問差異不顯著。 This study is aimed at developing composite varieties which are composed of promissing blast resistance lines from Taichung 184, 186, Taichung yu 115, Pino 4 and C 115, with the genetic background of varieties Tainan 5 and...

邱善美; S.M. Chiu.
[[abstract]]本試驗以9種肥料處理,採用隨時區組法設計,重複四次,以臺中65號為供試品種,同時在臺北二個場所進行試驗。 依據本試驗結果得知,由於氮、鉀之分施可以增加稻米產量,其原因乃由於每穗退化穎花數之減少,結實率及千粒重的增加所致。 The design of this experiment was a randomized complete block with 4 replications and 9 fertilizer treatments,the total plot was 36, the plot size was 102m. The trial was located at two villages near Taipei, Taichung 65 was used in the test, the plant spacing was 22.5 by 22.5cm, with 5 seedlings being transplanted at each hill.

許東暉; 黃真生; 鄧耀宗; 邱善美; T.H. Hsu; C.S. Huang; Y.C. Teng; S.M. Chiu.
[[abstract]]本試驗係以臺中65號×臺南3號與光復401號×臺農38號等兩個什交組合之Fl為供試材料,以臺南3號為對照品種。於民國58年第二期作,以二種不同氮肥用量及二種不同栽植密度,採用雙裂區設計法,期以探求水稻什種後代Fl在不同栽培環境下對稻穀產量之影響,其結果摘要如下: 1.生育日數因氮肥之增施而延長,因密植而縮短。供試材料中,以光復401號×臺農38號之Fl集團生育日數120天最短,對照品種之133天最長。 2.供試各處理之稻殺產量,因氣肥施用量之增加而減低。其主要原因乃受結責率及千粒重等低減之影響。 3.兩供試雜交組合之Fl在普通肥料用量下,密植較疏植為優。 4.不論為什種Fl或對照品種,於增肥環境下,疏植區之一穗粒數及千粒重等產量構成因素均優於密植區,因此其產量亦遠較密植區為高。 5.以此二組合產量言,光復401號×臺農38號之產量最高,次為對照品種臺南3號,臺中65號×臺南3號殿後。 1.The objective of this experiment is to study the response of two crosses of hybrid rice, Taichung 65 x Tainan 3 and Kwan-fu 401 x Tainung 38, which showed the highest hybrid vigor in terms of grain yield in 1968’s screening test.

灌溉水量與期距對水稻生育之影響 Taiwan Agricultural Research Institute
邱善美; S.M. Chiu.
[[abstract]]本試驗係以四種不同之水量及三種不同的灌期距,以臺中65號為試驗材料,以探討水稻之生育及產量與水之關係。在不同灌溉期距與水量之設計處理下,研討其對水稻之影響,進而覓求在不同氣候因子之影響下,觀察探求水稻一年二期作之各生育期耗水情形及有效降雨量之利用,對水稻產量之影響,其結果簡述如下: 1. 依據二年連續試驗之結果,在稻谷產量方面經變方分析結果,除1959年之第二期作各處理間有極顯著性差異外,其他各年期稻谷產量雖有多少之別,但併未達到顯著性程度,此種現象與前人研究所獲結果大致一致。 2. 積水灌區(C處理)營養生長極為旺盛,稻藁重及粃重均較其他處理為高,稻株易倒伏,稔實性差。 3. 在此四個處理中,以積水灌區耗水最大,D處理次之,A , B處理較少。以稻生育期別作比較時,則第一期作自成活期後耗水逐漸上升,至伸長期達最高。第二期作以成活期至分蘗前期較高,以後的耗水量逐漸減少。 4. 臺北地區,冬季雨量較多,自播種至插秧之一段期間多有降雨可藉利用,對稻作耕作大有俾益。第二期作除颱風暴雨帶來大量的雨水外,多屬乾燥天氣,人工給水屬大部份。如在農事耕作方面配合有效雨量,當可節省許多灌溉用水。 1.

秈稻白葉枯病抗病育種及遺傳之研究-Ⅱ.水稻品種BJ 1對白葉枯病抗病性之遺傳 Taiwan Agricultural Research Institute
許東暉; 鄧耀宗; 邱善美; T.H. Hsu; Y.C. Teng; S.M. Chiu.
[[abstract]]為研究水稻品種BJ 1等對白葉枯病抗病性之遺傳行為,利用感品種臺中在來號與高雄秈2號分別與BJ 1等抗病品種雜交,並於雜交後裔與親本在孕穗期間進行病原菌人工接種,接種20天調查其發病程度。試驗結果,BJ 1與TKM 6品種為親本所得F1、F2及F3雜種裔之反應,顯示水稻種品BJ 1具有抗病性,係受一對隱性因子控制;而控制TKM6之抗病性則對顯性因子,為後者與IRRI試驗結果一致。 The objective of this study was to investigate the mode of inheritance of resistance to bacterial leaf blight in rice variety BJ 1 (TKM 6 used as a check). The experiment was conducted at Taiwan Agricultural Research Institute in 1973. Two susceptible varieties Taichung Native 1 and Kaoshiung sen 2 were crossed with BJ 1 and TKM 6. The clipping method of inoculating the flag leaves was used for the test of bacterial leaf blight. Reaction was scored 20 days after inoculation on a scale of 0-9 based on the extent to which the lesion spread downward from the...

種子亞麻之生育及產量性狀與植期及播種密度之影響 Taiwan Agricultural Research Institute
邱善美; S.M. Chiu.
[[abstract]]亞麻莖之最大增長率出現日期,以S1,最早(播後30-40天),次為52、53及54(播後40-50天),其增長率分別為87.1、94.1、88.4及94.0%。但晚播者(S4)至播後之50-60天,仍有80.2%之增長車,顯示早播對莖之伸長發育有利,惟莖徑的增大,於亞麻發育初期(播後20-30天)即達40-72%,早播較晚播之增長率較低。 植期S1(10月5日)及S2(10月20日)之莖長大於植期S3(11月5日)及S4(11月20日),顯示早植可促進麻莖的伸長。但有效莖長,以S2最優(68.4 cm),次為S4(62.6 cm)及S3(62.2 cm),換言之,如種植亞麻之目的為採纖,其播種期仍以在11月上旬為宜,但如以種子為目的,則以10月上中旬種植產量最高,處理間差異顯著。10月5日(S1)播種者,各產量性狀如分蘗數、分枝數、全株朔果數,一個朔果種子數及千粒重等,概較其他三處理者為優。播種密度則以D4(900株/m2)及D3(1,350株/m2)之各產量性狀較D1(2,250株/m2)及D2(1,800株/m2)優異。

[[abstract]]水稻之栽培,慣例都採用純一(Pure line)品種,偶然發現異型植株,均於中耕除草時拔去,以保持品種的純度二而各稻作改良場亦竭盡全力以維護品種之純正為要務,故殊少在同一塊稻田混植二種以上不同之品種,究其目的,除可減少管理上的困擾外,咸認為種植純系品種,可獲得較整齊的產物及安定的收量。然不同品種間具有不同之形態、生理及其他如抗病性、抗蟲性等特性,故基於植物所具有不同之特性,就生理生態學的觀點言,品種間之混植是否較種植單一品種為有利,值得探討。 有關稻品種間之混植試驗,Sakai氏(1953),曾以四種梗稻及三種秈稻作混植及單植試驗,結果認為株重、單株穗數和穗重等三性狀,秈稻之競爭力大於稉稻。秈稉混植,稉稻之株重不如稉稻單獨植時大,但秈稻則較其單獨種植時為大。湯氏(1970)以五種稉稻及五種秈稻品種為材料,各以一秈、稉稻組成一組合(Combination),各組內分單植區及混植區二種,結果顯示:(a) 穗長、千粒重及結實率等性狀,不因秈稉稻品種之混植而發生變化。(b) 株高、穗重、穗數及單株空粒數等性狀在剛混植時不發生競爭,但隨混植年代之增加而漸發生競爭現象。(c) 單株充實粒數、每穗粒數、藁重、單株產量及單株總粒數等五性狀皆因不同因子型混植而發生生長競爭。(d) 特殊競爭現象,發生於每穗粒數及千粒重。由該試驗結果,顯示秈稉稻品種混植時,秈稻之生長競爭力強於稉稻。趙氏(1970)以稻熱病感應性不同之水稻品種或雜種集團,分別用二個或三個純系品種以1:1與1:1:1混合栽培,以測定對稻熱病罹病性之試驗,結果認為以抗或中抗級品種與中感或感級品種之混合集團,其罹病率均高於抗病品種,但低於感病品種,抗級品種與感級品種混合,其罹病率較中抗級品種與感級品種組合為低。...

稻苗耐寒性品種檢定試驗 Taiwan Agricultural Research Institute
邱善美; 漆匡時; 許東暉; S.M. Chiu; K.S.Chi; T.H. Hsu.
[[abstract]]本試驗係以本所保育的臺灣秈稻498品種及自大陸、IRRI引入之727水稻品種2~3葉齡之稻苗為檢定材料。檢定方法是藉恆溫箱(Incubator)以5℃處理48小時後,依稻苗成活率之高低為選留準則,而後將獲選的品種假嘉義分所以冷水槽(水溫10℃,處理10天)再行檢定一次。於第一期作,在天然低溫環境下,作秧床育苗為對照,期能選出耐寒性強之品種,供品種改良之需。 經用以上方法檢定後,計選出:有芒早十日、永川沙刁子、上杭大冬、山胄、瓜熟稻及菜園種具有耐寒性之品種。同時,在檢定方法上,不論是採用恆溫箱或冷水槽(Water bath)二者所獲結果頗為一致。 The rice seedlings at 2-3 leaves stage from 1,225 varieties (including 498 Taiwan Native Indica rice and 727 varieties from Mainland China and IRRI) were tested for chilling tolerance in an incubator maintaining at 5°C for 48 hours. The rate of survival was used for criterion of the responses of varieties to chilling temperature. The selected ones were tested again in a water bath at 10°C for 10 days. Afterwards, the seeds of the selected varieties were sown on nursery bed...

臺灣中部雙期作水田發展冬季裡作之研究-Ⅰ.早植稻不稔現象之發生 Taiwan Agricultural Research Institute
邱善美; S.M. Chiu.
[[abstract]]以早熟稻品種陸奧錦(Mutsunishiki)及中晚熟品種臺農67 號為觀察材料。經比較其生育期間晝夜溫差之結果,認為本期作所導致陸奧錦之不稔現象為夜低溫為主要原因。不稔穀粒之分佈,以穗端部最大,次為中部,基部最少,其稔實率分別為31.7 , 43.7 及62.3 %。此種現象與以稻穗支梗著生部位所調查結果甚為一致,但各次分蘗之稔實率則顯有差異,高節位之分蘗較低節位之分蘗之稔實率有較低之趨勢。農67 號未發生不稔現象。 稻因早植較一般移植者株高較低,二者相差14.3cm ( Mutsunishiki)及9.9 cm (臺農67 號)數亦以早植者優於一般植期者,各品種分別每株增加3.9 穗(Mutsunishiki)及3.0 穗(臺農67 號)。 An early maturing variety Mutsunishiki, and a medium-late variety, Tainung 67 were planted one month earlier than the conventional planting time of first rice crop to explore the possibility of early harvest of rice to be followed by the second crop of rice and the subsequent culture of upland crops during the winter season. A severe seed sterility occurred in Mutsunishiki, but not in Tainung 67. After recording of...
