Abstract:

A field experiment was carried out to explore the application effects of new fertilizer Ruitaifeng compound fertilizer on rice under reducing nitrogen condition. The results showed that, compared with conventional fertilization, the yields of Ruitaifeng treatment were increased by 2.94% and 3.30% under the condition of 7.3% nitrogen reduction, which were attributed to the increasing of the grain numbers per panicle and 1000-grain weight, and improved the quality of rice.

Key words: rice, Ruitaifeng compound fertilizer, yield, quality

摘要：

以常规施肥为对照，通过2年的田间试验，探讨了在减氮的基础上施用瑞泰丰复混肥对水稻生长发育和产量的影响。结果表明，与常规施肥相比，在减氮7.3% 时施用瑞泰丰复混肥，2年分别增产2.94%和3.30%，增产的原因主要是穗粒数和千粒重的增加，且改善了稻米品质。
