| 摘 要： | 通过田间试验,研究控释氮肥和普通氮肥对春玉米干物质积累与分配和氮素吸收与分配及玉米产量的影响.结果表明,施氮增加了玉米的干物质积累速率、氮素吸收速率及玉米产量.施用控释氮肥较普通氮肥提高玉米的干物质积累量及玉米植株的氮素吸收量,促进氮素向子粒的转移,子粒氮素所占比重达68.63%;控释氮肥较普通氮肥提高氮肥表观利用率5.21个百分点.

| Abstract: | A field experiment was carried out to study the effects of controlled-release nitrogen fertilizers(CRNFs) and common nitrogen fertilizers(CNFs) on dry matter accumulation and distribution, nitrogen absorption and distribution, maize yield. The results showed that dry matter accumulation rate, nitrogen uptake rate and maize yield were increased under applying nitrogen fertilizers, respectively. The amounts of dry matter accumulation and nitrogen absorption were increased under applying CRNFs compared with CNFs. And applying CRNFs could promote nitrogen translocation to grain, the proportion of nitrogen accumulation in grain by 68.63%. Nitrogen apparent use efficiency with applying CRNFs was increased by 5.21 percentage points than that with CNFs. |
