Abstract:: In order to strengthen the competitiveness of broccoli industry，a set of mathematical models between the plantation seedling (x₁),the planting density (x₂),the usage of nitrogenous fertilizer (x₃) and the reproductive stage (y₁) and yield (y₂) by the comprehensive research on these factors were constructed which regulated the reproductive stage and yield.The results showed that y₁=75.1322+1.6361x1-0.0001x₂＋0.0014x₃（r=0.8888**）,y₂=14 999.1852＋404.0006x₁-0.1986x₂＋3.6196x₃（r=0.6058**）.The rational use of the mathematical models made an improtant direction and referential value on safe allocation of production and standard cultural techniques in broccoli.
