| 摘 要： | 为了提高肥料利用率,改进和提高全肥一次性施肥技术,以‘先玉335’为材料,对玉米一次性分层缓释施肥技术进行了试验研究,对玉米生长发育、产量及产量构成因素进行分析。结果表明,由于利用硫包衣尿素的缓释作用和采用一次性分层基施,满足了玉米整个生育期对养分的需要,植株长势良好,比常规分期施肥增产12.1%。此方法打破了常规分期施肥的传统模式,减少因表施造成的肥料挥发损失,增加了产量,减少了生产环节,达到＂省工省时省费用＂的目的,可增加纯经济效益约1600元/hm2。

| Abstract: | In order to enhance fertilizer use efficiency and to improve QuanFei one-time fertilizer application technique,a field trial with a maize variety Xianyu 335 was conducted in 2010 in Hulan District of Harbin City,Heilongjiang,China,to investigate effects of one-time stratification application of slow-release fertilizera s base fertilizer on its growth and development,kernel yield and yield components under the conditions of no top dressing in the whole growth period.It is found that because the slow-releasing function of sulfur coated urea and the one-time stratification base application could meet the nutrient requirements of maize in the whole growth period,the plants grew well and made kernel yield 12.1%higher than the conventional stagingf ertilizer application patter.This application pattern broke the traditional pattern of staging fertilizera pplication,reduced volatile fertilizer loss caused by surface application,increased fertilizer use efficiencyb y more than 70%,enhanced kernel yield,reduced production processes,and thus reaching the target of cost-saving,saving-time and work-saving and increasing pure economic benefits by about 1600 yuan/hm 2 . |
