| 中文摘要: |
| 采用田间试验的方法研究了控释掺混肥在水稻上的应用效果。结果表明院控释掺混肥对水稻有增产效
果，与习惯施肥相比，等养分控释掺混肥处理产量可增加7.1%，减10%养分的控释掺混肥处理产量增幅为4.2%耀
6.1%，但减20%养分施用不利于水稻产量，产量下降8.5%。在田间试验中，控释掺混肥1 号每667 m2施用45 kg 在
水稻上经济效益最高，在水稻生产上显得更有优势，具有一定的应用前景。 |
| 英文摘要: |
| Field trial was conducted to evaluate the application effects of controlled-release mixing fertilizers on rice.
The results showed that application of controlled-release mixing fertilizers was beneficial to rice yield. Compared with
conventional fertilization, application of controlled-release mixing fertilizers with same nutrients, 10% decrement, 20%
decrement could increase yield by 7.1%, 4.2%-6.1%, -8.5%, respectively. The controlled-release mixing fertilizer (No. 1)
had the most economic benefits among the fertilizers in field trial, suggesting that the amount of fertilizer was 45 kg per
667 m2, and it may had potential as a commercial fertilizer. |
