| 摘 要： | 为探究缓控释复合肥在籼粳杂交稻生产上的应用效果,方法]在田间小区试验条件下研究对比不同量的缓控释复合肥和常规施肥对水稻“甬优12”产量、品质和经济效益的影响。试验设置5个施肥处理：不施肥(CK)、常规施肥(RF)、100%缓控释复合肥(100% CRF)、80%缓控释复合肥(80% CRF)和60%缓控释复合肥(60% CRF)。结果]整体而言,100% CRF对水稻产量、经济性状指标、稻米品质指标和经济效益的提高最好,例如,增加水稻的精整米率和碱消值,降低垩白粒率和粗蛋白含量；80% CRF对水稻指标的影响与RF相近；而60% CRF处理的水稻产量、株高、有效穗和经济效益均明显低于RF。结论]研究结果表明,在一定范围内,施氮量仍然是限制水稻产量和影响水稻品质指标最重要的元素,因而今后在研制和推广缓控释复合肥时应着重考虑其氮素水平。

Effects of Slowed Controlled-release Fertilizers on indica-japonica hybrid rice yield, quality and economic benefits |
| |
| Abstract: | Abstract: Objective] In order to explore the application effect of slowed controlled-release fertilizers on indica-japonicabrid rice productivity, Method] a field experiment was conducted to investigate the responses to different application rate of controlled release fertilizers and regular fertilizer to rice grain yield, quality and economic benefits of Yongyou 12. Five fertilizer treatments were compared, including control (CK), regular fertilizer (RF), 100% slowed controlled-release fertilizers (100% CRF), 80% slowed controlled-release fertilizers (80% CRF) and 60% slowed controlled-release fertilizers (60% CRF). Result] The research achievement shows overall, 100% CRF had the highest improvement on rice grain yield, economic indicator, rice quality and economic benefits, which can increase the head rice rate and alkali spreading value, but decrease the chalky rice rate and crude protein content. 80% CRF had the similar effect on rice as RF, but 60% CRF had a lower improvement on rice grain yield, plant height, effective panicles and economic benefits compared with RF. Conclusion] The results indicate that nitrogen is the most important element which controls the rice grain yield and quality, thus nitrogen application rate should be firstly considered when the slowed controlled-release fertilizers is developed and generalized. |
