摘要
为了探究增效磷肥在东北黑土区玉米上的应用效果,通过2年的田间定位试验,研究施用不同增效磷肥处理的玉米产量、磷素吸收量、磷肥农学效率和偏生产力。试验结果表明,与磷酸二铵相比,施用Ⅰ、Ⅱ、Ⅲ号增效磷肥后玉米产量平均增加4.1%、4.8%、9.1%;磷肥利用率分别提高1.0、1.3、2.7个百分点;农学效率分别提高4.8、5.7、10.6 kg/kg。总体而言,与磷酸二铵相比,增效磷肥提高了玉米的产量和磷肥利用率,其中增效磷肥Ⅲ号的玉米产量、磷肥利用率和农学效率提高幅度最大,应用效果最佳,具有较好的应用潜力。
In order to clarify the effect of synergistic phosphorous fertilizer application on spring maize production in black soil area, grain yield, P uptake and use efficiency of maize, agronomic efficiency, partial fertilizer productivity were measured in this study by conducting field experiment for 2 consecutive years containing conventional fertilization and different phosphorous fertilizer synergist treatments. The results showed that compared with conventional phosphate fertilizers, the application of Ⅰ,Ⅱ and Ⅲ synergistic phosphate fertilizers increased the grain yield by an average of 4.1%, 4.8%, and 9.1%;the utilization rate of phosphate fertilizer increased by 1.0, 1.3, and 2.7 percentage points, respectively. The agronomic efficiency increased by 4.8, 5.7, 10.6 kg/kg. In general, synergistic phosphate fertilizers have improved grain yield and fertilizer utilization. Among them, synergistic phosphate fertilizer type Ⅲ has the largest increase in grain yield, phosphate utilization and agronomic efficiency. Hence, the synergistic phosphate fertilizer type III has cheerful prospect in application.
