脲甲醛缓释复混肥料在花菜上的应用效果研究

Study of Application Effect of Urea-Formaldehyde Slow-Release Fertilizer on Cauliflower

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。

In order to identify agricultural applying technique and fertilizer effect of urea- formaldehyde 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 resuhs show that applying urea- formaldehyde 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.
