摘  要：
采用包膜控释氮肥在玉米上进行肥效试验研究。结果表明,与普通氮肥(尿素)相比,控释氮肥由于其本身控制释放和缓慢释放的特点,能使耕作层土壤速效氮含量在玉米生育期内维持较高的水平,满足玉米生长对氮素的吸收需求,尤其能满足玉米中后期对养分高强度吸收的需求;显著提高玉米生长中后期植株体内氮素含量,加速氮磷钾向籽粒的转移,从而提高生物产量、经济产量和玉米品质。同等和减半施氮量条件下,玉米产量和氮素利用率都有显著提高。

摘  要：
The effects of coated controlledrelease nitrogen fertilizer(CRNF) on corn yield increase are studied.The results show that:CRNF supplies the available nitrogen in surface soil with a higher level throughout the whole growing season of corn to meet the requirement for nitrogen uptake by the plants,especially for the intensive nitrogen uptake during the middle,late period of the growing season,compared with common urea.The transportations of N,P,K into grains are speeded up,the nitrogen contents in the plant and grain are increased by application of CRNF,which result in higher biological & economic yields and quality.The corn yield and nitrogen use efficiency are significantly increased with the same or half nitrogen amount treatments of CRNF.
