2-Amino-4-Chloro-6-Methyl Pyrimidine 抑制氮肥硝化作用之研究(第二報) Taiwan Agricultural Research Institute
徐水泉; 溫西濱; S.C. Hsu; C.P. Wen.
[[abstract]]1.本試驗係根據第一報(農業研究第16卷第1期)之試驗結果繼續檢討AM對中壢粘土,香山砂土,屏東壤土等不同性質土壤中,硝酸化作用抑制效果及對水稻產量之影響。 2.據土壤實驗結果得知AM對氮素之硝酸化作用抑制效果受土壤性質之影響並不大而對砂土的效果較優。 3.盆栽試驗結果AM對容易發生脫氮作用環境下對水稻直播栽培稻谷產量之增收均有效果。 1. Following the preliminary report, the effect of A.M. was further studied on certain soils of varied properties. 2. The effect of A.M. was larger in sandy soil than in loamy or clayey soil. 3. A.M. may be advantageous for the cultivation methods under which denitrification is inevitable. (e. g., direct, sowing of rice under upland condition.)

2-Amino-4-chloro-6-methylpyrimidine抑制氮肥硝酸化作用之研究(第1報) Taiwan Agricultural Research Institute
溫西濱; H.P. Wen.
[[abstract]]本試驗之目的為探討2-Amino-4-chloro-6-methylpyrimidine(簡稱AM)之施用對于水稻產量之影響,及對土壤中硝酸化作用之抑制效果,於1966年間採用直播栽培法舉行水稻盆栽試驗,並在實驗室內分析土壤中之NH3-N和NO3-N生成量,以究明所施尿素之銨化及硝酸化情形,測定AM之硝酸化抑制效果。 據盆栽試驗結果AM之施用對于稻谷之增收確有效果,土壤實驗結果示AM對尿素之銨化作用並無影響,但對其硝酸化卻有顯然抑制效果。 由以上結果可以推知AM在容易發生脫氮作用之環境下(如輪流灌溉地區或缺水地區水稻直播栽培)對于氮素肥料肥效之增進將有裨益。但實際應用效果如何尚待繼續試驗。 To test the effect of 2-Amino-4-chloro-6-methyl pyrimidine (A.M.) as a nitrifica-tion inhibitor in soil and its applicability in rice culture, a pot experiment under which loss of nitrogen by percolation and denitrification prevailed was conducted. A. M. was observed not to affect the rate of ammonification of urea, whereas the nitricfication was significantly suppressed by A. M. and the availability of the fertilizer applied for the plant was highly...

PCP尿素對於水稻之肥效及除草效果試驗 Taiwan Agricultural Research Institute
溫西濱; H.P. Wen.
[[abstract]](l)本試驗為探討PCP尿素中含有之「PCP-Na」對於水田雜草之殺草效力及氮成分之硝酸化成抑制效力對水稻之生育,產量的影響,而在臺北、桃園兩地舉行田間試驗同時在實驗室內進行化驗分析。 (2)田間試驗結果PCP尿素對於水稻收量增產之影響較優於尿素,其原因可推定為「PCP-Na」之硝化抑制作用及殺草力之影響所致。 (3)PCP尿素之「PCP-Na」成分具有硝酸化成之抑制力同時對銨化作用有阻礙之傾向。 (4)PCP尿素施用過量時對農作物具有藥害作用,故其PCP-Na使用量每公頃10公斤左右較為適宜,在此範圍內水稻之生育初期雖受接觸藥害之影響,但至生育後期即可漸次恢復自然,不致影響稻谷產量。 (1) Field experiments were conducted at Taoyuan and Taipei areas to compare the fertilizer effect of PCP-urea with that of urea. The nitrification inhibitory effect of PCP-urea was also tested in the laboratory. (2) With the same rate of nitrogen, PCP-urea gave a slightly higher grain yield than urea in the experiment, which might be attributed to both the nitrification inhibitory and the weed controlling effect of PCP-Na cantained in PCP-urea. migh be...

PCP鈣氰氮化鈣對水稻之肥效及除草效果試驗(第一報) Taiwan Agricultural Research Institute
林國謙; 溫西濱; 王清演; K.C. Lin; H.P. Wen; C.Y. Wang.
[[abstract]]本試驗於民國五十一年在桃園、屏東兩地舉行田間試驗,其結果提要如下:由試驗結果觀之,PCP鈣氰氮化鈣在第一期作,若充為基肥施用時,其肥效雖接近硫酸銨區之收量,但半量氮素以PCP鈣氰氮化鈣充為基肥,餘半量氮素以硫酸銨充為追肥施用時,其肥效與硫酸銨施用區之收量相差無幾。在第二期作PCP鈣氰氮化鈣之肥效遠優於硫酸銨施用區,換言之,PCP鈣氰氮化鈣對水稻之增產效果,在第二期作較優於第一期作。 至於對除草效果而言,氰氮化鈣+五鈣酚鈉區,效果最優,PCP鈣氰氮化鈣區次之,氰氮化鈣區又次之,硫酸銨區最差。 就生育狀況而言,氰氮化鈣+五鈣酚鈉區及PCP鈣氰氮化鈣區兩處理生育初期雖受PCP之藥害而生育被抑制,但以後漸次恢復,至生育後期共生育狀況即遠超出其他各處理區。 The experiment was conducted in Taoyuane and Pintung for two crops in 1962. The result indicated that the availability of PCP-Calcium Cyanamide was corresponding to that of ammonium sulfate in the first crop and was even superior than the latter in the second crop. Besides its availability as a nitrogenous fertilizer, its effect on weeding was also significant. Though the early growth of paddy was a little effected by the...

主要作物施肥適量試驗 十、鳳梨施肥適量試驗 Taiwan Agricultural Research Institute
林國謙; 邱再發; 溫西濱; 李蘭帝; K. C. LIin; T. F. Chiu; S. P. Wen; L. T. LI.
[[abstract]]本試驗於民國44~46年在嘉義、鳳山及民國49~50年在彰化等三地舉行鳳梨施肥適量試驗,其試驗成績結果如下: 1. 肥料處理對鳳梨果實產量之影響: 氮肥對鳳梨果實增產之效應甚為明顯,尤以彰化、鳳山兩地即顯著增收到32~140%(與無氮區比較)之多,而以氮多量區及氮最多量區之收量最優。就磷肥之影響而言,肥效可謂甚微,難以判別磷之效應。就鉀肥之影響而言,其效應亦不甚明顯,僅嘉義乙地增收2~7%左右外,彰化及鳳山即呈負之效應。 2. 肥料三要素對鳳梨果實品質之影響: 氮肥之施用影響果肉之還元糖,全糖量及顏色深黃等效果顯著,增施氮肥可使酸度降低風味佳優之良果。施用磷肥之果實風味最劣。鉀肥之施用具有促進增加全糖量之傾向。總括而言,欲求得甜酸適度,風味佳良,肉色深黃之鳳梨果實,需施用量之氮、鉀兩要素為改進品質之主要條件。 The experiment on N. P and K requirements for pineapple growing were conducted duing the periods of 1955 to 1957 at Chiayi and Fengshan and 1960 to 1961 at Changhua.

主要作物施肥適量試驗:二、甘藷施肥適量試驗 Taiwan Agricultural Research Institute
林國謙; 溫西濱; K.C. Lin; H.P. Wen.
[[abstract]]本試驗係于民國四十年起至民國四十二年止,分別就全省選定八處舉行。三年之試驗成績結果如下: (1) 肥料處理對辦甘藷莖葉及塊根之影響 氯之施用對甘藷莖葉之增收率最顯著,在坐標上產量對施肥量幾乎成為直線型,並不因過多肥料之施用而降下。對塊根之產量則有一較低的限度。雖依地方而異,一般在60公斤/公頃時可得最高收量,其對無氮區之增產率為20~30%。因此過多氮之施用僅有甘藷蔓之繁茂而對塊根之增產無補於事。燐之施用對甘藷莖葉之收量影響最少。對塊根之收量則除臺北、臺中、臺南、高雄四地區在50公斤施用量時對無燐區之增收率有10至20%外,其他地區均不顯著。鉀之施用對於甘藷藷葉之增收亦無顯著之效果。對於塊根之收量則平均在170公斤/公頃的施用量時有20至30%之增收率。故充分使用鉀肥以提高產量可認為非常重要。 (2) 甘藷三要素適量 由本試驗測出各地欲得最高收量時之三要素施用量如下: (3) 甘藷之慣行施肥量 就農家慣行施肥量調查所得施肥量分別就各地區計算其要素量如下: 農家慣用肥料中以有機質遲效性肥料為大宗,各種肥料作物利用率不相同,故實際施肥量又須考慮各種肥料之作物利用率而定,一般言之,農家對甘藷之施肥,氮與燐可酌量減少而須增多鉀之用量。 (4) 經濟的施肥量 經濟的施肥量亦經決定,在目前可獲得最高利潤之肥料施用量如下表: Optimum fertilizer application rate is a basic knowledge on fertilizing technics. Since 1950, Society of soil scientists and fertilizer technologists of Taiwan designed a 5 years plan to...

氮磷化成肥料對水稻之效應試驗 Taiwan Agricultural Research Institute
吳啟東; 溫西濱; 林國謙; C.T. Wu; H.P. Wen; K.C. Lin.
[[abstract]]為明瞭使用氮磷化成肥料栽培水稱時之適當使用方法在民國46~48年間選擇臺北、桃園、埔心、員林等地舉辦田間試驗,每試驗地均同樣設置12處理4重覆隨機排列法之田間設計,由本次試驗結果顯示單使用氮磷化成肥料對于水稻生產效果較使用硫酸錏為差,若使用硫酸錏為基肥氣磷化成肥料當追肥使用時之水稻產量較高於全部使用氮磷化成肥料。各試驗處理區谷實收量指數總平均如下。 Field experiments were conducted in Taipei, Taoyeun, Pushin and Yenlin in order to find the most effective method of application for the nitrophosphate. The experimental design has 12 treatment with 4 replication arranged in randomized black. It was found in these experimental results that nitrophosphate alone gave yield less than that of ammonium sulphate. When ammonium sulphate was used as base manure and nitrophate as top-dressing, the crop yield was also higher than that of using nitrophosphate alone.

洋菇覆蓋土改良之研究-土壤團粒及各種物質對洋菇產量之影響 Taiwan Agricultural Research Institute
溫西濱; 林登鴻; H.P. Wen; T.H. Lin.
[[abstract]](1)根據實驗分析結果得知土壤之孔隙量及容水量由團粒之大小不同而有差異即粒徑愈小其容水量愈大,在孔隙量粒徑愈大亦隨之大,各種不同材料中蔗渣的孔隙量與容水量均較高於穀殼粉及泥炭。 (2)土壤團粒之大小對洋菇產量以土壤粒徑1.0mm~0.5mm較優,泥炭對洋菇產量,土壤混合率25%處理區最高,若泥炭的用量過多時雖不致減少,也無法提高洋菇產量,穀殼粉土壤分層使用可能保持良好的孔隙量故其產量較優於土壤混合使用區,蔗渣本身之容水量孔隙量雖然高於其他材料區,但不見到較好的效應。 (3)本次試驗僅探討土壤團粒度,及泥炭,穀殼粉,蔗渣等與土壤混合做覆蓋土時之孔隙量,容水量之差異情形及洋菇生產之影響,獲得初步結果,卻尋求理想的覆蓋土,土壤應有之處理或產量之影響尚待今後繼續研究。 The porosity and water holding capacity as well as the effect on mushroom yield of various casing soils which differ either in the size of granule or in the material incorporated (i. e., peat power. husk powder and bagasse power) were tested in this experiment. The primary results obtained were as follows: (1) The optimum size of granule for casing soil was observed about 1.0 mm~0.5 mm. (2) Among the casing soils...

甘藷膠質肥料肥效試驗成績(第一年) Taiwan Agricultural Research Institute
林國謙; 溫西濱; K.C. Lin; H.P. Wen.
[[abstract]]一般化學肥料常因雨水或滲透水而易流失,尤以磷酸肥料施用後易與土壤中之鐵、鋁等成分結合,變成難於被植物吸收之形態,損失其肥效。膠質肥料即為防止上述事項而製成者,而以造成肥料成分充分被植物利用之形態為目的。日本平野博士使用Gelatin系兩性Colloid製成。膠質肥料是進行Arnmoniation而中和遊離酸之際,依據所生成之Gelatin而進行Ammouiation直接作用於磷酸鈣,因此而防止過磷鈣肥效之減低,又因形成粒狀,故防止水溶性化學肥料即時溶出,一部份成為複雜的鹽類,具有遲效性等特長。 本試驗之目的乃探討膠質肥料與一般化學肥料比較試驗之效果,自民國44年6月在本所及三重鎮農家兩地舉行膠質肥料對甘藷之肥效試驗,於民國45年3月完成。茲將第一年試驗成績列表於後。 Colloidal fertilizer is manufactured by ammoniation on the free acid to make it chemically neutral and protected from fixation of phosphorous with colloid in the form of granulars as it will prevent the readily solving out of the element. The purpose of this experiment is to compare the effectiveness of colloidal fertilizer with that of other fertilizers, and was carried out in Taipei and Shanchung. The results...
