Abstract: Abstract: Based on a l5-year located field experiment at Bixi village Tonghai county of Yunnan province, this paper studied the yield-increasing effect and yield-stabilizing feature of different fertilization systems under rice- broad bean rotation. The results showed that fertilization had obvious influence on crop output， and the average output of rice was decreased in the order of OM+NPK>NPK>OM>CK，the average output of faba bean decreased in the order of OM+NPK> OM > NPK >CK. OM mixed or substituted with NPK conduced to high and steady yield of rice and faba bean，and contribution rate of fertilizer. And the faba bean could develop healthily and increase yield by proper P and K or microelement fertilization supply at its development stage, not only before rice planted.
