幾種主要蔬菜害蟲藥劑防治田間試驗 Taiwan Agricultural Research Institute
秦登; 梁同庭; 林勝吉; T. Chien; T.T. Liang; S.C. Lin.
[[abstract]]蔬菜多為短期而直接銷售之農作物。農民為提高其所植蔬菜之品級,就必須施用藥劑,以保護其產品使絕對不受害蟲之為害。惟蔬菜害蟲之種類複雜,且多不易防除;加以菜價波動,菜農之收益不能獲得保障,故菜農必須在各方面設法減低其耕作成本。因此有些菜農在蔬菜上乃使用價廉、效強,但有損於人體健康之高毒性農藥。除此之外,由於蔬菜上已連續多年施佈農藥,乃至增加昆蟲之抵抗力,故既或使用高毒性農藥亦必須提高其使用濃度及用量,否則亦難奏效,故農藥遺毒問題乃漸趨嚴重,而構成目前之一重大社會問題。 A project of vegetable insect pests control with comparatively safe insecticides had been conducted from 1962 to 1963. The chemicals used in the studies ware selected from a number of the newly developed insecticides, which had already been screened by the Pesticide Laboratory of Taiwan Agricultural Research Institute; they were 50% DDVP (Nogos 50 E, Ciba Ltd.), 85% sevin WP (Union Carbide Chem. Co.), 50% sumithion E C [O,O-dimethy1-O-(3-methyl-4-nitrophenyl) phosphorothioate, Sumitomo Chem. Co.], 35% thiodan E C...

柑桔嫁接應用植物荷爾蒙試驗(第一報)應用植物荷爾蒙提高柑桔嫁接成活率 Taiwan Agricultural Research Institute
翁仁祿; J.L. Weng.
[[abstract]]本試驗從民國五十一年七月起,至民國五十二年六月止計一年,其目的在應用植物荷爾蒙刺戟柑桔接枝切面細胞促進其分裂,增強癒合能力,以探求柑桔嫁接之周年成活問題,本試驗採用β-Iodoleacetic acid, β-Indolebutyric acid水溶液各 50 , 100 , 200 ppm 濃度及羊毛脂軟膏各 500 , 1,000 , 2,000PPm 濃度分為八、十、十二、二、四及六月之六次施行嫁接,嫁接後一個月打開包紮物檢查成活率。 1. 植物荷爾蒙水溶液處理區,周年之成活率均高,似乎對提高柑桔嫁接成活率有貢獻,尤其十月,六月之兩月份效果較為明顯。 IB , IA 兩種植物荷爾蒙間及各種濃度間並無顯著差異。 2. 植物荷爾蒙羊毛脂軟膏處理區,羊毛脂對接穗,砧木兩者密接上似乎有阻害,成活率頗低,遠不如對照區。 This experiment was carried out in the Department of Horticulture of Taiwan Agricultural Research Institute from July 1962 to June 1963. The purpose of this experiment was to promote the ability of callus on the part of grafting and to increase the percentage of citrus graft by using plant hormones all the year round. The kinds of plant hormones used were β-Indoleacetic acid (IA) and...

謝全份; 高樹; 江忠; C.F. Hsieh; S. Kao; C. Chang.
[[abstract]]1. 為探討水稻收刈後之再生力及產量之品種間差異乃利15種蓬萊種及兩種在來種進行田問試驗結果認為有生育日數長的品種再生力較強。 2. 一般而言移植稻之稈長較宿根稻為高其穗數亦較宿根稻多1-2支。 3. 生育日數均以宿根稻為短,移植稻為長相差日數7-10天。 4. 本試驗供試品種範圍內稻谷收量均以移植稻為高宿根稻皆低,兩者之差異甚為顯著。 5. 宿根栽培品種間產量之差異在統計上極為顯著其最高品種與最低品種之相差達40-50%之鉅。 1. Fifteen “ponlai” and two “native” varieties of rice were used for studies of varietal variation in ratooning ability and yield. It was found that the varieties with longer growing days tended to have stronger ratooning ability. 2. Generally speaking, culm height and number of ears in transplanted rice are larger than those of ratooned rice. 3. The number of growing days in ratooned rice was 7—10 days earlier than that of transplanted rice. 4. Significant difference between yields of transplanted and ratooned rices was found. The...

稻熱病菌對水銀離子耐性之研究 Taiwan Agricultural Research Institute
簡錦忠; C.C. Chien.
[[abstract]]本試驗係於實驗室內探討兩種不同生理小種之稻熱病病原菌,由於連續施用水銀劑後是否可能產生變異性耐藥菌種而舉行,其結果簡述如下: 1. 致病力強之稻熱病菌生理小種,對 HgCl2 之自然抵抗性為0.050mM,致病力弱之生理小種為0.082mM。 2. 供試兩生理小種對水銀離子顯示不規則之耐性增強。培養至第六代達0.375mM為最高耐性。此後再連續培養四代,均未有增加耐性之趨勢。 3. 供試耐藥菌(0.114 mM)之兩種生理小種,連續培養於無藥劑之基本培養基內,其對水銀離子耐性之增加一致保持在0.20 mM,似可認本菌對水銀離子具有永續耐性。 4. 根據處理前與處理後之菌種接種於16種稻品種上所呈現病斑之差異,測定其病原性之結果,耐藥菌之病原性均強於連續培養後之正常菌,與處理前母菌之病原性比較,致病力強之生理小種耐藥菌與母菌完全相同,連續培養之正常菌且有退化現象。致病力弱之生理小種耐藥菌及正常菌均比母菌為強。 In order to determine the drug resistance of Piricularia oryzae, the rice blast fungus, against mercuric chloride (HgCl2), two different physiologic races of P. oryzae were tested in this experiment. The results are summarized as follows: (1) The natural drug resistance of OS-45S, a strongly virulent race is at 0.05 mM; while 1C-32S, a weakly...

稻葉鞘腐敗病發生之觀察 Taiwan Agricultural Research Institute
陳其昌; 簡錦忠; C.C. Chen; C.C. Chien.
[[abstract]]本報告係關於稻葉鞘腐敗病之病原菌(Acrocylindium oryzae Sawada)之生存力,被害稻對產量因子之影響,該病之發生與其他病害蟲之關係,稻品種間之罹病程度,以及該病之發生與施肥之關係等諸項在田間或室內之觀察結果,摘述如下: 1. 稻葉鞘腐敗病病原菌放置於冷藏室(15℃)或室內(15~28℃)溫度下,其生活力到第10個月呈較衰弱,第12個月時即失去生活能力。 2. 被害稻不能抽穗狀況,蓬萊稻似較在來稻嚴重。被害稻之糙米的長度,寬度及厚度等均比健全稻之糙米為短、薄。故如大發生時對產量之影響頗大。 3. 本病之被害穗莖,被螟蟲害者有56~57%之多,罹黃萎病者有7~21%,而被害穗均無其他病害蟲之侵害者僅有22~35%。 4. 觀察209稻種之感病程度,在田間自然發生率在2.1~5.0%之間佔大多數,又一般看之印度型稻草內之品種較日本型稻羣內之品種的感病性品種稍多。 5. 增施氮肥之用量時,其發病率稍有增加,又鉀肥之分施也有增加發病之傾向。 1. When the artificial cultures of Acrocylindium oryzae Sawada were kept either in a cold room with constant temperature at 15°C or at room temperture (15-28°C), the vitality was greatly affected after 10 months. In fact, the viability was completely lost after 12 months. 2. Heading was greatly impaired by disease,...

綠豆象藥劑防治試驗 Taiwan Agricultural Research Institute
林欉; T. Lin.
[[abstract]]綠豆象切蟲之嗜好豆類,以紅豆及綠豆最為嗜好,被害最為嚴重,大豆、青皮豆之被害較輕,豌豆、烏豆、花生仁等似不受其害。該蟲之防治方法雖多,但在本省環境下,當以採用豆類混拌粉劑,即在倉庫貯藏期間或至批發各地出售時期,均可獲得理想之治蟲效果。 本試驗計有粉劑 : Bromodan、Alodan、Premium malathion、Malathion、Lindane等五種,對綠豆象孵化幼蟲之接觸毒殺效力,以Bromodan與Alodan 粉劑之殘毒治蟲效力為最佳,Lindane粉劑次之,Malathion與Premium malathion為最短。 豆類混拌粉劑之適當施用藥量,切勿以經濟著想,而使用低濃度,以免日後發生害蟲對藥劑產生抗毒性,致失藥劑治蟲之能力,故應選擇較高濃度為優。在豆類收獲後可用5% Bromodan或5% Alodan粉劑任選一種,與豆類每千公斤使用粉劑0.4~0.5公斤混拌,即可達到治蟲目的,同時並可防止其他貯藏害蟲之發生。 Callosobruchs chnensis Linne is a serious pest of beans. The damage caused by the beetles on red beans, green beans, green soy beans, peas, black beans and peanuts have been observed. Red beans and green beans are comparatively heavy infested by the pest; soy beans and green soy beans are slightly infested. It seems that no...

纖維作物腰折病之研究1. 纖維作物腰折病菌(Pellicularia filamentosa (Pat.)Rogers)之生態研究 續) Taiwan Agricultural Research Institute
杜金池; C.C. Tu.
[[abstract]]1. 本研究之目的為探求P. filamentossa在黃麻引起子苗立枯型腰折病所需之土壤溫度,濕度。並於土壤內增用植物添加物及不同氮素源,觀測是否可抑制病害之發生。 2. 黃麻幼苗在土壤溫度10~35℃均可發生腰折病,23~27℃最適宜於發病,而以25℃發病最激烈。 3. 土壤濕度以10~45%含水量均可使黃麻幼苗發生腰折病。在此範圍內,含水量愈少發病愈烈、20%含水量發病最多。土壤過濕或過份乾燥,則可使麻株生理異常增加死亡。 4. 土壤中加入植物有機質可使黃麻種子減少P. filamentosa侵害,其結果尤以太陽麻稈添加物時最顯著。兩種不同氮素源,NH4NO3及Uramite各以l00ppm加入各添加物處理內,可明顯減少種子被感染及幼苗死亡,罹病程度等。若僅二種化學氮素源相比較,則速效性NH4NO3顯然比遲效性 Uramite更見效。 5. P. filamentosa菌株對黃麻精洗麻纖維素破壞能力互不相同,菌株 K2 , T 及 B2 等3菌株對纖維素破壞能力最強,次為 K3 , J , B1,及R等4菌株。菌株U則完全不具破壞能力。 1. The purpose of this study is to determine the soil temperature and moisture which are favorable to Pellicularia filamentosa causing seedling damping-off of jute. Five Kinds of mature plant materials and 2 forms of supplemental nitrogen were added in the sick soil to test...

纖維作物腰折病之研究1.纖維作物腰折病菌(Pellicularia filamentosa (Pat.) Rogers.)之生態研究 Taiwan Agricultural Research Institute
杜金池; C.C. Tu.
[[abstract]]一、Pellicularia filamentosa之8菌株分離自一般纖維作物,6菌株分離自其他作物,其寄主範圍均相一致,惟因菌株之不同對各類作物可呈現強弱不一之病原性。 二、分離自纖維作物病株之Pellicularia filameutose 8 菌株以側定棉及黃麻不同生育狀況之感病程度差異性,結果於不同菌株間,病原性可發生差別之事實,固不待言,然棉與黃麻因生育狀態不同而感染之易否亦可發生差異。棉以苗齡愈小,罹病愈容易。黃麻則以發芽後5~15日之間罹病指數最高,過此時期,雖亦可發病,但其程度急劇降低。 三、分離自纖維作物病株之Pellicularia filameutosa 8 菌株用以測定菌絲之癒合現象(Fu-sion of hyphae)結果,各菌株之菌絲癒合之程度不盡一致。其中以菌株 K l 與 C , T 與 F K3與 K 2與 T , K 3 與 U , C 與 T , U 與 F 及 T 與 F 均可進行完全癒合現象。 四、供試Pellicularia filamentosa各菌株對纖維素之破壞能力,因不同菌株而發生差異。菌株 K 2 破壞能力最強,次為菌株 T , U P,最弱都為菌株F,僅可發生極輕微破壞現象。 1. Among 14 isolates of Pellicitlaria filamcntosa, 8 isolates were isolated from the fibre crops and 6 from other plants. They had the same host range, but the pathogenicities of these isolates were quite different on various...

耕耘機水田適用性試驗 Taiwan Agricultural Research Institute
鄔清標; C.P.Wu.
[[abstract]]1. 各種整地方法對土壤及作物生育,產量之影響,在試驗期間未能發現顯著之差異。 2. 耕深除無變速裝置3~4.5馬力之迴轉驅動型耕耘機未能達到牛耕深度外,其餘均比牛耕為深。3. 本省水由之理想耕深應為20~25公分,但各供試機器均未能達到20公分以上之深度。 4. 為達成深耕目的必須研究心土犁及振動犁等耕耘機用心土破碎器具。 5. 平均耕地時問各種機器均比牛耕為快,但有些地區反比牛耕為慢,至使實際作業效率只達理論作業效率之43-65%,普通應為60~80%,其原因可歸列為: i 作業耕深均大於作耕耘機耕速之統計時之耕深(12~14公分) ii 駕駛員之行速未能達到l m/sec之行速而仍舊保持駛牛耕地時之行速(0.7 m/sec)至使影響工作效率。 iii 車輪及耕具未能完全配合各地之土壤情況,至使有些地區發生作業困難,如機器之沉沒,土草之附著等等。 6. 在試驗期間未有適合之整平器具影響作業效率至巨,只達正常作業效率之40~60%。 7. 由於作業效率低、用油量經濟度只達正常狀態之75~80%。 8. 牽引型耕紜機每公頃整地成本為 700 元,驅動型為 777 元,牛耕為 1,233 元,機耕較牛耕為省,但牛耕之成本多為非現金支出,對農家經濟之影響不顯著,但耕耘機之成本多屬現金支出,對農家之經濟有明顯關係,故必須善於經營以提高經營所得或保持耕耘機之年使用時間在500小時以上始可得到械化之利益。 7. 農作制度之地域性複雜,機器成本高,年使用時數減少,及附屬農具未能適合作業要求,至使今幾年之耕紜機推廣情形未能達到政府之預定目標。 10. 今後應盡量簡化耕紜機之機構以降低成本,並須配台各地域之農業制度研究地域性之附屬農具。 1.

曾憲鼎; 王接皇; H.D. Tseng; C.H. Wang.
[[abstract]]一、為研究臺灣粘板岩質沖積土有效性磷量與水稻生長效應之相關,在臺灣十七個地區採取之粘板岩質沖積土之稻田土壤於溫室中進行水稻盆栽試驗。 二、盆栽試驗之處理分為NPK及NK,每處理重複三次,每盆N, P2O5及 K2O之施用量按照處理各為120公斤/公頃。 三、採用五種方法以測定土壤之有效性磷量,即(l) 0.1N NaOH 抽出法,(2)Olsen氏之0.5M NaHCO2法,(3) Bray 氏之 0.025N HCI 及0.03 N NH4F法,(4) Bray氏之0.1 N HC1及 0.03N NH4F法,及(5) Mehlich 氏之0.05 N HC1 及 0.025 N H2SO4 法。 四、五種方法測定之土壤有效性磷量與稻谷產量百分率之相關,其中有三種方法達於相關顯著之標準,三種方法中以Olsen氏方法最優,Bray氏第一法次之,0.1 N NaOH 法略差。 五、五種方法測定之土壤有效性磷量與水稻磷酸吸收量之相關,其中有四種方法達於相關顯著之標準,其中以Olsen氏方法最優,0.1 N NaOH 法次之,而 Mehlich 氏方法顯然不適合作為測定臺灣粘板岩質沖積土稻田土壤有效磷用。 六、根據初步研究結果對臺灣粘板岩質稻田土壤可採用Olsen氏方法或Bray氏第一法以測定土壤之有效性磷,如按二法所測定土壤之有效性磷(P)量均在 10 ppm 以下時,施用磷肥對水稻可獲得增產效果。 1.
