摘要: 试验在湖北省荆门市沙洋县曾集镇比较了宜施壮控释肥不同的控释时间及施肥方式对水稻(Oryza sative L.)植株生长及产量的影响。结果表明, 水稻生长施用控释肥具有缓慢释放养分的作用, 能与水稻的生长期保持一致, 并能满足水稻高产稳产需求;控释肥处理区的株高、穗长、千粒重和水稻专用肥区、常规施肥区均无太大差别, 但可以明显提高水稻有效穗数、每穗实粒数;水稻控释肥CRU1产量最高, 比不施氮肥对照增产3 135.0 kg/hm2, 增产率为43.5%;比常规施肥对照增产1 800 kg/hm2, 增产率为21.1%。

Abstract: The experiment was conducted in Zengji town, Shayang county, Jingmen city, Hubei province, to compare the effects of different controlled-release time and fertilization methods on rice (Oryza sative L.) plant growth and yield. The results showed that controlled-release fertilizer could release nutrients slowly and keep pace with the growth of rice, and could meet the demand of high and stable yield of rice. The plant height, panicle length, 1 000-grain weight of controlled-release fertilizer treatment area were not significantly different from those of special fertilizer area and conventional fertilizer area, while the application of controlled-release fertilizer could significantly increase the effective panicle and the number of grains per panicle of rice. Controlled release fertilizer CRU1 increased yield by 3 135.0 kg/hm2 and 43.5% compared with no fertilization control, and 1 800 kg/hm2 and 21.1% compared with conventional fertilization control.

Key words: controlled release fertilizer, rice(Oryza sative L.), yield, economic benefits
