Abstract：

    The purposes of this program were to establish the environmental friendly rotation models for vegetable soybeans in export professional fields and onions in Henchun area. The experimental results of vegetable soybean rotations were summarized as follow during the fall crop in 2011 to the summer crop in 2013. Rotation model A was the highest annual profits by 121,860 NTD/ha, which was 69.3% higher than check treatment D. The rotation treatments B and C had higher annual profits, which were 26.9% and 8.1% higher than check treatment. On onion rotation trails, the onion yield of green manure soybean rotation system was 61.3 mt/ha which was the highest. The onion yields were 59.7 mt/ha and 53.5 mt/ha by sesbania rotation and forage maize rotation respectively. The biomasses of forage maize, green manure soybean and sesbania, were 51.8 mt/ha, 26.0 mt/ha and 28.8 mt/ha respectively. The growths of 3 rotation crops were limited by rainfall within seedling stage. The second rotation crop was affected by 2 typhoons that induced serious crop damage and all crops were lost.
