摘要： 摘要：通过云南省通海县碧溪村15年的定位施肥田间小区试验，研究了水稻蚕豆轮作条件下4种施肥制度的增产效应和稳产性能。结果表明：不同施肥制度对作物产量有明显的影响，水稻平均产量OM+NPK>NPK>OM>CK，蚕豆平均产量OM+NPK> OM > NPK >CK，农家肥化肥配施或者农家肥替代化肥有利于水稻蚕豆轮作体系作物高产、稳产，提高肥料贡献率。同时，只在前茬作物水稻进行施肥不能满足后茬作物蚕豆正常生长发育的需要，要实现蚕豆高产、稳产需要适当施用磷、钾肥及微量元素。

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.
