摘要
文以鲜食玉米'SBS902'为试验材料,设置6个不同处理,研究缓释肥对鲜食玉米产量和品质的影响.结果表明,在施氮量相同的情况下,缓释肥代替普通尿素可显著提升玉米产量及品质,增加玉米种植经济效益.缓释肥减施10%,玉米产量及品质可达到普通尿素水平,缓释肥减施10%～20%范围内鲜食玉米种植经济效益仍然高于普通尿素.综合考虑,认为T2处理(施入318.18 kg/hm2缓释尿素)是最佳的缓释肥施入量.
Abstract
This paper uses'SBS902'fresh corn variety as the experimental material,and sets up six different treatments to study the effects of slow-release fertilizer on the yield and quality of fresh maize.The results show that under the same nitrogen application rate,the replacement of ordinary urea with slow-release fertilizer could significantly improve the yield and quality of maize,increase the economic benefits of maize planting,and reduce the application of slow-release fertilizer by 10%achieves the same yield and quality level as ordinary urea,within the economic benefits of fresh maize planting in the range of 10%-20%of slow-release fertilizer reduction is still higher than that of ordinary urea.Considering all factors,Treatment T2(applying 318.18 kg/hm2 of slow-release urea)is deemed the optimal dosage of slow-release fertilizer.
