缓释尿素对黔中黄壤区鲜食玉米产量及品质的影响

Effects of Slow-release Urea on Yield and Quality of Fresh Maize in Yellow Soil Area of Central Guizhou Province

通过田间肥效试验,探究黔中黄壤区施用缓释尿素对鲜食玉米的产量、品质的影响。结果表明,施用缓释尿素处理鲜食玉米产量为(9.04±0.16)t·hm^(-2),较施用普通尿素增产5.02%,增加纯收益7180元·hm^(-2);鲜食玉米总糖、氨基酸、维生素C、蛋白质较施用普通尿素处理略有提高,但效果不明显。研究表明,在黔中黄壤区域鲜食玉米生产上施用缓释尿素综合效益较好。

The effects of slow-release urea application on the yield and quality of fresh maize in yellow soil area of central Guizhou were studied by field fertilizer effect experiment.The results showed that the yield of fresh maize treated with slow-release urea was(19.04±0.16)t·hm^(-2),which increased by 5.02%compared with that of ordinary urea and increased by 7180 yuan·hm^(-2).The total Sugar,Amino acid,Vitamin C and Protein of fresh corn were slightly improved compared with those treated with ordinary urea,but the effect was not obvious.In general,the application of slow-release urea in the production of fresh maize in the yellow soil area of central Guizhou had better comprehensive benefits.
