摘　　要：以云南省普洱市墨江哈尼族自治县通关镇为试验地点,考察缓控释肥料对水稻产量和品质的影响。结果显示,缓控释肥料的缓释期可对水稻生长形状与产量产生影响,当水稻品种为清香优2238与深两优2808时,缓释期为100天的缓释氮肥效果要优于60天缓释期。清香优2238在B2条件下的产量最高为9.61 t/hm^(2),深两优2808在B2条件下的产量最高为11.78 t/hm^(2)。60天缓释氮肥处理下的杨籼优919产量优于100天缓释氮肥,A3条件下杨籼优919产量较高为10.68 t/hm^(2)。Tongguan Town of Mojiang Hani Autonomous County was selected as the test site to investigate the effect of slow controlled release fertilizer on rice yield and quality.The results showed that the slow-release period of slow-release fertilizer could affect the growth shape and yield of rice.When the rice varieties were Qingxiangyou 2238 and Shenliangyou 2808,the effect of slowrelease nitrogen fertilizer with 100-day slow-release period was better than that with 60-day slow-release period.The highest yield of Qingxiangyou 2238 under B2 conditions is 9.61 t/hm2,and the highest yield of Shenliangyou 2808 under B2 conditions is 11.78 t/hm2.The yield of Yangxianyou 919 treated with 60 days of slow-release nitrogen fertilizer was better than that treated with 100 days of slow-release nitrogen fertilizer,and the yield of Yangxianyou 919 under A3 condition was 10.68 t/hm2.
