本計畫之目的為建立花蓮、宜蘭地區適合的耕作模式，以水稻耕作模式為基礎，在花蓮地區配合雜糧作物、宜蘭地區與青蔥輪作栽培，並配合種植綠肥等之作物，期能在水旱田輪作及種植綠肥作物的情況下，提高作物生產價值，友善對待農業環境之較佳水旱田輪作模式，同時穩定農民收。花蓮地區之水旱田輪作模式初步結果顯示在一期作大豆、二期作水稻耕作模式之親和型及傳統栽培間的大豆籽粒產量無明顯差異；一期作硬質玉米、二期作水稻耕作模式之親和型的玉米籽粒產量則較傳統栽培法略為減產；一期大豆或硬質玉米，二期種植水稻的輪作模式之水稻產量以傳統栽培較親和型栽培之稻穀產量高。宜蘭地區青蔥及水稻輪作栽培模式之建立，於宜蘭縣三星鄉進行水稻與青蔥輪作之試作，101 年試驗一期作種植水稻，處理組減用2 次化學農藥，結果顯示在產量及病害罹病率上均無顯著差異；二期作種植萬壽菊綠肥及田菁綠肥，比較其對下年度青蔥生育之影響。102 年試驗輪作青蔥，處理組前作為萬壽菊綠肥，化學農藥防治次數減少20%，對照組前作為田菁綠肥，1 期作處理與對照間產量無顯著差異；2 期作調查處理組單欉重較對照組高15%。103 年一期作輪作水稻，處理組減用2 次化學農藥，結果處理組之稻穀產量較對照組高6%，成效良好，未來可推廣農友使用非農藥防治法，減少化學農藥之使用，建立親和型栽培模式。
The aim of this project is to establish rotation planting models suitable for farming in Hualien and Yilan areas that are friendly to the agricultural environment, and are able to improve the value of crops and to increase the income of the farmers. The model in Hualien area is rice rotates with upland crops. The model in Yilan area is rice rotates with green onion, upland crops and green manure. The productivity of both traditional and eco-friendly planting model (application of fertilizers and pesticides) in soybean-rice rotation and corn-rice rotation adapted in Hualien area were about the same. The productivity of both traditional and eco-friendly planting model in soybean-rice rotation indicated no significant difference on yield, in corn-rice rotation traditional cultivation planting model corn grain yield higher than eco-friendly planting model, in soybean-rice rotation and corn-rice rotation traditional cultivation planting model rice grain yield higher than eco-friendly planting model in Hualien area. The model in Yilan area is rice rotates with green onion, upland crops and green manure. Experiment on rice rotates with green onion was made in Sanxing township, Yilan county. We cultivated rice on first crop, and sowed green manure crops marigolds and sesbania on second crop this year. The investigate results indicated no significant difference on yield, occurrence of rice blast and rice sheath blight disease existed among tests. Then we planted green onion at 2013. The results showed that there is no significant difference on first crops among tests. But the yield and horticultural character of treatment were better than the control on second and third crop. At 2014, ear we cultivated rice “Taikeng No.8” on first crop, and sowed green manure crops marigolds and sesbania on second crop. The investigate results indicated the yield of treatment were better than check, and no significant difference on occurrence of rice blast and rice sheath blight disease existed among tests.
