摘　　要：在25℃静水释放试验条件下,对2种控释BB肥的控释性能进行了研究。结果表明:2种控释BB肥对养分均有一定的控释性能,对氮素的控释效果最好,磷、钾控释效果较差。两种控释BB肥相比,控释BB肥1对氮的控释效果优于控释BB肥2,而控释BB肥2对磷、钾的控释效果优于控释BB肥1。The nutrient release characteristics of two different controlled-release BB fertilizers in the 25 water are studied. The results show that 2 kinds of controlled-release BB fertilizers have the effect of nutrient controlled release, which is better in nitrogen, and is poor in phosphorus and potassium. Nitrogen controlled release effect of controlled-release BB fertilizer 1 is better than that of controlled-release BB fertilizer 2, which is opposite to phosphorus and potassium.
