Abstract
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 .关键词
