控释氮肥在插秧水稻上的施用效果

摘要

On the basis of field experiment in 2012, to continue the experiment of different controlled release fertilizer on rice growth and yield of rice transplanting in 2013, the results show that one-time use of 60 days and 90 days two kinds of controlled release fertilizer on planting rice, rice yields were 672.3 kg and 679.7 kg, to effect a bit better of 90 days controlled release fertilizer, the difference is not obvious about two fertilizer use and conventional fertilization. Through field experiments for two consecutive years, understanding the effects of controlled release nitrogen fertilizer on rice growth and yield conditions, in order to explore the fertilizer application prospects and corresponding technical measures on rice production in Yinchuan .%在2012年田间试验的基础上，于2013年继续进行不同控释肥对插秧水稻生长与产量的影响试验.结果表明：在插秧稻上一次性施用60 d和90 d 2种控释肥时，水稻产量分别为672.3、679.7 kg/666.7 m2，以90 d控释肥效果较好，分2次施用和常规施肥差别不显著.
