摘要
采取田间小区试验,研究美国Koch公司AGROTAIN氮稳定剂对中稻产量以及氮肥利用效果的影响。结果表明:施用AGROTAIN氮稳定剂可缩短中稻全生育期,提前1～2 d成熟;可有效降低中稻的株高,降低倒伏风险;超级杂交中稻增产2. 74%～10. 63%,常规优质稻增产3. 84%～7. 26%;施用AGROTAIN氮稳定剂可提高中稻氮肥偏生产力、氮肥农学利用效率、氮肥表观利用率。
A field plot experiment was conducted to study the effects of AGROTAIN nitrogen stabilizers on the yield of mid - season rice and nitrogen use in Koch. The results showed that the application of AGROTAIN nitrogen stabilizer could shorten the whole growth period of mid - season rice and mature at 1 - 2 d in advance ; it could effectively reduce the plant height of middle rice and reduce the risk of lodging; the yield of super hybrid mid - season increased by 2. 74% 10. 63 % , and the yield of conventional high - quality rice increased by 3.84 % ~ 7. 26 % ;application of AGROTAIN nitrogen stabilizer in medium rice can increase the partial productivity of nitrogen fertilizer, the agronomic utilization efficiency of nitrogen fertilizer, and the apparent utilization rate of nitrogen fertilizer.
