本試驗探討幾種主要作物施用有機肥並配合間作物栽培，以選出適宜共榮與有益作物組合。試驗結果顯示，在單作區施用有機肥較化肥處理區平均增產11.3%。施用有機肥間作區比單作區，在各主作物分別為甜玉米增產19.3%，馬鈴薯增產6.5%，毛豆增產36.9%，大蒜增產5%。而施用化學肥料間作區比單作區，各主作物分別為毛豆增產55.4%，大蒜增產7.9%。適宜之共榮作物組合為秋季甜玉米間作毛豆、或矮性菜豆、豌豆、花豆、花生、油菜、蔓性菜豆等。冬季主作馬鈴薯間作花豆、或豌豆、矮性菜豆。春季主作毛豆間作蘿蔔、或萵苣、白菜等。冬季主作大蒜間作胡蘿蔔或菠菜等。試驗結果並顯示間作可顯著提高主作物甜玉米、大蒜之糖度。

This studies were aimed to compare the effects of synergistic crops and organic fertilizer on the growth of main crops in intercropping systems. The results showed that the average yield of main crops under monocropping with organic manure application were 11.3% higher than that with chemical fertilizer application. Yield of main crops under intercropping system were higher than that under monocropping, i.e. 19.3 % yield increase for sweet corn in the fall, 6.5% yield increase for potato in the winter, 36.9% yield increase for vegetable soybean in the spring, and 5% yield increase for garlic in the winter crop season, respectively. It was observed that under the organic fertilized condition, sweet corn performed much better in grain yield when intercropping with synergistic crops bush kidney bean, green pea, green shell bean, peanut, edible rape or pole kidney bean in the all crop season. Potato was observed to have much higher yield when intercropped with the leguminous crops, green pea and kidney bean, in the winter season. Vegetable soybean performed better when intercropped with radish, lettuce or Chinese cabbage in the spring crop season. Further, it was suggested from the presented experiment that garlic intercropped with radish and spinach was a good combination of synegistic crops in the winter crop season. It was concluded that leguminous crops are good crops to be used as synergistic crops to interplant with the main crops under the organic farming system.
