通过自制长效包膜肥与常规施肥在草地早熟禾盆栽上的试验研究表明,在同一施肥量的情况下作基肥一次施入,长效包膜肥在整个试验期间可以满足早熟禾整个试验期对养分的需求,但常规施肥则出现了缺肥症状。包膜肥加工过程及加入缓释剂对N素养分和P、K养分的释放规律有所不同:缓释剂的加入有利于提高N肥效但却加速了肥料中P、K的释放;包膜却对N、P、K均有延缓释放的作用。
Through self-made long-term coated fertilizer and conventional fertilization in pots of Kentucky bluegrass trial showed that in the same amount of fertilizer applied as a base fertilizer, long-term coated fertilizer throughout the test period to meet the whole bluegrass season The demand for nutrients, but the conventional fertilization appeared lack of fat symptoms. The release of N and N nutrition and P and K nutrients were different in the processing of coated fertilizer and the addition of slow release agent. The addition of slow release agent was beneficial to increasing N efficiency but accelerating the release of P and K in fertilizer. However, N, P, K have delayed the release of the role.
