【摘要】 为明确脲甲醛缓释复混肥料在农业上的施用技术及肥料效果、为花菜的绿色生产提供科学依据,研究了脲甲醛缓释复混肥料对花菜植株长势、产量、氮素利用率等指标的影响。研究结果表明:施用脲甲醛缓释复混肥料能够有效促进花菜的花球膨大,提高养分利用率,并可提高花菜产量;能减少氮肥的挥发和淋溶损失,减轻施肥对环境的污染;省时、省工,具有较大的社会效益和生态环境效益。更多还原

【Abstract】 In order to identify agricultural applying technique and fertilizer effect of ureaformaldehyde slow-release fertilizer,providing scientific basis for green production of cauliflower,a study is carried out of the effect of urea-formaldehyde slow-release fertilizer on growth,yield,and nitrogen use efficiency of cauliflower and other indicators. Research results show that applying ureaformaldehyde slow-release fertilizer can promote ball-flower intumescence,improve nutrient utilization,and increase output of cauliflower; it can reduce volatilization loss and leaching loss of nitrogen fertilizer,lessen environmental pollution brought by fertilizer application; it can save time and labor,having greater social benefit and eco-environment benefit.更多还原
