三島柴胡臺農1號之育式 Taiwan Agricultural Research Institute
劉新裕; 徐原田; 胡敏夫; 邱善美; S.Y. Liu; Y.T. Shyu; M.F. Hu; S.M. Chiu.
[[abstract]]三島柴胡臺農1號之親本源自日本之三島柴胡,為常異交作物,自交純化不易。本所自民國57年引入三島柴胡種子後,即利用混合選種法,淘汰生產力顯著低落及品質較劣植株,並選拔生長勢旺盛及高saponin含量之植株,混合其飽滿種子,共經七年選種而成。並依序進行品種觀察試驗、品種比較試驗、產量調查及三次區域試驗,綜合上述試驗結果可知,新品種具有產量穩定、品質優越及適應力大之優點。在乾根平均公頃產量方面,新品種高出三島柴胡約27.7%,在saponin含量方面,新品種為三島柴胡之1.12倍高,此外新品種之適應能力大增,已能在較高溫之平地栽培,且植株間之變異程度已經減小。因此獲得審查通過,命名為三島柴胡臺農1號。 三島柴胡臺農1號之植株生育強健,一年生株高可達80cm,莖直立質堅,葉互生,植株下半部葉形較大,葉長約15cm,寬約1.5cm,花為複繖形花序,果實為分裂果,種子長橢圓形,千粒重1.23─1.68g。由歷年各地區試驗根產量之綜合比較可知,栽培於中高海拔山坡地一年生根產量都在l , 000 kg/ha以上,平地一年生產量約為690 kg/ha,一年半生為1,168 kg/ha,根中saponin平均含量為2.75%,變域為1.05─7.43%。 Bupleurum falcatum L. cv. TARI No. 1 was developed through mass selection from three sources of Bupleurum falcatum L. imported from Japan in 1968. Stable yielding potential, high quality, and wide adaptability of the new...

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.

仙草不同生長期之主成份含量分析 Taiwan Agricultural Research Institute
胡敏夫; 林禮輝; M.F. Hu; L.F. Lin.
[[abstract]]以4個仙草品種為材料,於移值後120、150、180及190天分別收穫,以探討生育期長短對仙草莖葉主成份含量變化之影響。試驗結果發現仙草莖葉之粗蛋白質含量隨著生長日數增進而降低,但脂肪含量與纖維含量則隨著生長日數增進而增加。可溶性無氮物(Nitrogen free extract)和乾物質(Dry matter)含量於180天生長期較高。因此,以可溶性無氮物及乾物質含量作為仙草採收指標,則其最適採收期,應當於移植後180天為佳,不需待至植株花蕾形成期。 Four varieties of hsian-tsao (Mesona procumbens Hemsl), i. e., small leaf runner type, small leaf bunch type, big leaf bunch type, and big leaf runner type, were harvested on the 120th, 150th, 180th and 190th day after transplanting. Gross composition of stems and leaves were analyzed and compared at these different growth stages. The results showed that crude protein content in the stems and leaves of hsian-tsao varieties all decreased during the developing stages. However, the crude fat and crude fiber content...

仙草品種與植期對產量及主成份含量之影響 Taiwan Agricultural Research Institute
胡敏夫; 林禮輝; M.F. Hu; L.F. Lin.
[[abstract]]以4 個仙草品種,分3 月16 日及4 月16 日二期移植,探討不同移植期對該等品種之農藝性狀,產量及主要化學成份含量之影響,結果顯示在二移植期公頃平均乾草量,小葉匍匐種(A)為4,529kg,小葉直立種(B)為5,043kg ,大葉直立種(C)為4,735kg 及大葉匍匐種(D)為6,915kg。但就移植期別加以探討,發現A 、C 和D 三品種第一移植期較第二移植期高產,尤以D 品種在第一期移植公頃乾草量6,932kg 為最高。另就仙草主要化學成份分析結果,發現品種間之可溶性無氮物(NFE)含量差異不大。至於影響仙草凍凝膠強度,可能因品種間之葉量百分率高低有關之假說,經就化學成份分析顯示並未被證實。 Four varieties (A-small leaf runner type; B-small leaf bunch type; C-big leaf bunch type; D-big leaf runner type) of hsian-tsao (Mesona procumbens Hemsi) were transplanted on March 16 (S1) and April 16 (S2) 1984 to evaluate the effect of variety and transplanting date on the agronomic characters, dry grass weight and gross composition. Based on the average of 2 transplanting dates, variety A, B, C and D produced 4529, 5043, 4735 and 6915 kg/ha...

山藜豆植物性狀與適應性之研究 Taiwan Agricultural Research Institute
胡敏夫; 邱善美; M.F. Hu; S.M. Chiu.
[[abstract]]從印度ICRISAT 引進山藜豆(Chick pea)11 品系,第一年行缽栽觀察,第二年行田間栽培觀察,分別探討其植物性狀及其在本省適應性。經二年觀察結果,發現本類作物適合本省冬季期間栽培,且所參試品系中,以K1(白花種No. 4973)產量較高,平均公頃產量為1,019 kg。至於植物性狀之觀察,經調查詳述於本文中。 Eleven varieties of chick pea (Cier arietinum L. ) introduced from ICRISAT, India, were grown in pots as well as in the experimental field in TARI, Taichung, Taiwan, during the years of 1979-1980. The botanical characteristics and their adaptability were investgated. We found that most varieties of chick pea grew vigorously in winter time. Among the entires tested, variety K1 (Kabuli type No. 4973) yielded 1019 kg/ha, which was the highest among the varieties tested.

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...

氮肥種類及施用期對藺草產量及品質影響 Taiwan Agricultural Research Institute
胡敏夫; 曾束海; M.F. Hu; T.H. Teseng.
[[abstract]]於藺草不同生育期,分別施用硫酸錏與尿素,以比較兩種氮肥對藺草生育及產量等之影響。經二年試驗結果顯示,(1)乾草重兩年綜合分析結果,各處理差異不顯著,即施用硫酸錏與尿素兩者肥效無大差異,惟施用方法可考慮以前、中期施用硫酸錏,後期施用尿素較佳。(2)藺草莖部氮素含量分析結果,各處理在不同生長期莖部含氮量均超過2%以上,意謂兩種型態的氮肥,供給氮素養分均很充足。收穫後土壤殘留氮素量之測定,各處理土壤含氮量均比種植前含量高,但處理問差異極微。(3)全期施用尿素區,肥料成本比對照區(全期施用硫酸錏)每公頃可節省2,898.30 元,但每公頃乾草重與乾草價值比對照區減產7%或減收15.1%。 The present experiment was conducted to study the effects of two nitrogen fertilizers on the yield and quality of mat rush over two years (1977 and 1979) . The results are summarized in the following: 1. No significant difference in fertilizer response was observed in term of dry weight of the glass between two kinds of fertilizers However, for good management of fertilizer application, it is suggested to apply ammonium sulphate at the early stage and urea...

瓊麻園雜草種類及施用殺草劑效果之評價 Taiwan Agricultural Research Institute
胡敏夫; M.F. Hu.
[[abstract]]自從人造纖維發明和取代部份之植物纖維用途後,瓊麻纖維之價格一落千丈,農民因無利可圖,未能如往年再僱工除草,於是麻園裡雜草叢生,威脅著瓊麻生長,遭致麻絲產量逐年降低,而不能充分供應國內需要。為要解決此問題,爰進行本計畫並於1977~1979 年問從事研究。經試驗調查結果,發現較常見生長於瓊麻園裡之雜草有39 種,其中禾本科(Gramineae)佔最多,次為莎草科(Cyperaceae)及菊科(Coopositae)。以不同種類殺草劑噴施調查各種雜草殘存率,獲知禾本科抗藥性較大,殘存率高,次為莎草科、豆科(Leguminosae)及石竹科(Cayophyllaceae)。莧科(Amarau - thaceae)及菊科之雜草,全部死亡。各處理間對殺草效果,成本分析及對瓊麻生長之評價,發現噴施混合藥劑之B 處理每公頃使用85% Dowpons 8 kg 加2-4-D 2kg 或D 處理每公頃使用80% Kamex 2 kg 殺草效果較佳,且比人工除草區各自增產13 和20%,比不除草區各自增產58 和68%,同時每公頃較人工除草區節省生產成本4,696 和5,400 元。 Because the uses of sisal hemp fiber can be substituted by the synthetic products, the cultivation and price of sisal hemp are greatly reduced. In addition, the widespread of different weeds in sisal hemp field also influences the growth of sisal hemp plants....

金線連大量繁殖與栽培後之生育性狀、種間比較及營養成分研究 Taiwan Agricultural Research Institute
劉新裕; 蔡新聲; 黃漢津; 胡敏夫; 葉常青; S.Y. Liu; H.S. Tsay; H.C. Huang; M.F. Hu; C.C. Yeh.
[[abstract]]金線連之無菌培殖體培養於含5ppmBA及0.3%活性碳之基本固體培養基上,可誘導8倍芽體之生成及根系之正常發展,金線連之無菌小芽於液體震盪培養後,亦能得到大量繁殖的結果。 金線連組織培養瓶苗於馴化、假植及擇健株定植於1100m之霧社地區,其成活率達90%以上。臺灣金線連在18個月之生長期中,平均每個月植株增高、增重及莖徑加粗之速率為0.5cm、0.2g及0.2mm。產量增加較大的三個生育期,即第10、12及18個月,應為採收的較佳時期。生長15個月後,臺灣金線連比高雄金線連有較小的株高及節間距離,但其莖徑較粗且葉長、葉寬、葉重及葉面積較佔優勢,所以有較大的鮮重。 臺灣金線連之營養成分中除含水率達87%,尚含甚高量之脂質、維生素C及礦物質。脂質及維生素C之含量遠高於一般之果蔬類食品。兩種金線連在C、P、K、Na及Mg五種重要礦物元素之含量亦甚高,每1OOg中分別含有Ca279mg、P193mg、K806mg;Na188mg及Mg270mg。此外,尚含有Fe 51.7mg、Mnl3.8mg、Zn9.3mg及Cu2.6mg。 Shoot tips of pearl orchid (Anoectochilus sp.) plants were cultured in vitro and node segments of the derived plants were subcultured in either liquid or solid medium aimed to develop a method of mass propagation of this rare medicinal herb. Results showed a multiplication rate of 8.5...

食用美人蕉品種間農藝特性及澱粉含量之研究 Taiwan Agricultural Research Institute
胡敏夫; M.F. Hu.
[[abstract]]本文目的在探究食用美人蕉品種之農藝特性及澱粉性質,發現紫紅色種之生長勢較綠色種為強,公頃塊莖產量亦較高,但差異不大。不同生長序之塊莖產量與全部塊莖產量之比,兩品種均以第3 及第4 分蘗所佔之百分率較高分別為27.5%與28.7%(紫紅色種),及23.8%與23.5%(綠色種)。塊莖澱粉含量亦以第2 至第4 分蘗之塊莖較高,各為65.3%、61%、64%(紫紅色種)及59.2%,64%、65%(綠色種),顯示促進該等分蘗塊莖數量及發育為提高食用美人蕉產量之重要關鍵。不同生育日數對塊莖澱粉含量經測定結果,得知塊莖澱粉蓄積量隨著生育日數而增加,但最適當之收獲時期,應在植株開始枯萎且新芽未萌發前為宜。自澱粉粒觀測發現,該兩品種之澱粉粒均比其他澱粉作物之澱粉粒為大,澱粉純度高,尤以綠色種為最,此或可解釋綠色種廣被農民栽培之理由。 A comparative study on yield and starch content of two edible canna varieties, namely, the green and the purple canna, was carried out in 1982. The results showed that the growth of the purple variety was more vigorous than that of the green one. The tuber hectare yield of th purple variety was also higher than that of the green one, but without significant difference. Each canna plant...
