摘  要:
比较了包膜控释肥料在水旱2种模拟形式下的释放率变化情况。结果表明:在同等条件下,包膜控释肥料在水田的养分累计释放率大于旱田。包膜控释肥料前期的释放速率是水田明显高于旱田,而后期的释放速率则为旱田略高于水田。土壤物理形态的差异对包膜控释肥料的养分释放有很大影响。

摘  要:
The changes of release rate of coated controlled release fertilizer in paddy farmland and dry farmland were compared.The result showed that the accumulative release rate in paddy farmland was higher than that in dry farmland under the same condition.The release rate in paddy farmland was significantly higher than that in dry farmland at the earlier stage,while was slightly lower than that in dry farmland.The physical form of soil had great influence on the release rate.
