摘　　要：通过分析发现我国复合肥中等养分配比(15-15-15)的通用型产品仍是主流,其市场占有率达到54%,而专用型复合肥约占46%,大型企业仍以生产养分含量大于40%的高浓度产品为主。目前这种高浓度、一次性基施通用型复合肥的发展现状已与实际需求不符,土壤养分大量累积、肥料价格高昂等新形势需要精确的综合管理养分。应该根据土壤养分测试结果开发专用配方复合肥,发展特定作物、特定生育期的系列专用型复合肥。With 54% market share, common type product （ 15-15-15 ） of compound fertilizer in China is still main variety, compared with 46% market share of special type of compound fertilizer. Meanwhile high- analysis product of compound fertilizer is also with beyond 40% nutrient contents. Above-mentioned status of compound fertilizer development with high-analysis, once base fertilizer only and common type results in the deviations of real demand, both the huge amount of accumulated nutrients in soil and high price of compound fertilizer needs accurate management of comprehensive nutrients, a series of special type of compound fertilizers should be developed based on the soil test for proper crops in some a growth period.
