  本試驗旨在探討不同耕作制度對土壤肥力、作物需水量、作物田間雜草、病蟲害發生及作物收益之影響。各耕作制度分為:A.水稻─水稻(對照)、B.水稻─田菁-飼料玉米、C.水稻─田菁─青割玉米、D.水稻—向日葵—油菜、E.綠肥大豆─青割玉米、F.太陽麻─飼料玉米等六種處理。試驗結果,各耕作制度全年田間總用水量,以處理A:水稻─水稻(CK)之公頃總用水量27,939立方公尺最多,處理E:綠肥大豆─青割玉米2,802立方公尺最少。其減少灌溉水量19,258 (m3/ha),節省灌溉水效益103,993元/公頃最高,較處理A:水稻-水稻(CK)節省灌溉水97%。各耕作制度全年作物淨收益,以處理B:水稻—田菁-飼料玉米之公頃淨收益111,858元最多。全年作物公頃淨收益加節省灌溉水效益,以處理E:綠肥大豆-青割玉米之196,374元最高,較處理A:水稻-水稻(CK)之107,590元增加83%。

關鍵詞:耕作制度、水稻、田菁、飼料玉米、青割玉米、綠肥大豆、向日葵、太陽麻、油菜

Studies on Cropping Systems of Upland crop and Paddy Rice
in Yin-Chia-Nan District

Chan, B. L., P. S. Wang and Y. S. Chan

Abstract

   The purpose of this study is to evaluate the effect of rice and upland crop rotation systems on the soil property, fertility, density of weeds, disease, insect pest, and crop yield. The experiment was conducted from 2009 to 2011. Six cropping systems contained: (A) Rice-Rice (CK) , (B) Rice-Sesbanias-Field corn, (C) Rice-Sesbanias-Forage corn, (D) Rice-Sunflower-Rape, (E) Green manure soybean-Forage corn, (F) Crotalaria-Field corn. The results are summarized as follow: The total water consumption for treatment A (rice–rice, CK) had the highest water demand 27,939 m3/ha, and the treatment E (green manure soybean-forage corn) had the lowest water demand 2,802 m3/ha. The treatment E reduced 97% of the water consumption (19,258 m3/ha) than treatment A, and saved producing cost NT$103,993. The annual net income of treatment B was the highest (NT$111,858). However, the annual net income plus amount of irrigation water in treatment E was the highest, which was 83% higher (NT$196,374) than treatment A.
