摘要： 毕节地区农业科学研究所于2001-2002年度进行了有机生物复合肥不同底肥施用量对玉米产量及经济效益的影响试验。结果表明：以20kg/667m2有机生物复合肥作底肥的单位面积产量、产值和纯经济效益最高，其次为40kg/667m2，施用量超过80kg/667m2后，玉米的产量显著下降，产值降低。

Abstract: We engaged in experiment that effect of organic biology compound fertilizer with different base-fertilizer application-rate on maize yield and economic benefit in 2001-2002.The results indicated:base-fertilizer is 20kg/667m2 organic biology compound fertilizer,maize yield and economic benefit is the high est;The next is 40kg/667m2;When application-rate surpasses 80kg/667m2,maize yield drops remarkably and output value reduces.
