[目的]为研究胶粘型控释肥(CRF)对玉米农艺性状及生理指标的影响。[方法]通过盆栽试验,对比了施用控释肥(CRF)和两种传统施肥模式(CF)条件下玉米农艺特性及生理指标的差异。[结果]与传统施肥模式相比,施用控释肥后,玉米的株高、茎粗、叶面积和根体积均有显著的提高,且光合速率及叶片可溶性蛋白的含量也有提高。两种控释肥处理的干物质积累较传统肥料一次施肥处理(CF1)分别提高了21.3%和17.0%,较传统肥料分两次施肥处理(CRF2)分别提高了19.6%和15.4%。与传统施肥模式相比,控释肥处理植株N、P、K积累量的提高幅度分别为44.0%~24.7%、40.0%~25.9%和20.1%-13.9%;养分利用率的提高幅度分别为22.9%~13.4%、11.2%~9.6%和17.5%-12.1%。[结论]胶粘型控释肥能够显著的提高玉米的养分利用效率和玉米产量。
[Objective] The research aimed to study the effect of adhesive controlled release fertilizer (CRF) on agronomic traits and physiological indexes of corn. [Method] The pot experiment was conducted to compare the differences of corn agronomic characteristics and physiological indexes under the condition of controlled release fertilizer (CRF) and two traditional fertilization modes (CF). [Result] Compared with the traditional fertilization mode, the plant height, stem diameter, leaf area and root volume of maize increased significantly and the photosynthetic rate and leaf soluble protein content also increased after applying controlled release fertilizer. The dry matter accumulation of the two controlled-release fertilizers increased by 21.3% and 17.0%, respectively, compared with the conventional fertilization (CF1), which was 19.6% and 15.4% higher than that of the traditional fertilization by two fertilizers (CRF2) respectively. Compared with the traditional fertilization model, the N, P, K accumulation of the controlled-release fertilizer treatments increased by 44.0% -24.7%, 40.0% -25.9% and 20.1% -13.9%, respectively. The improvement rates of nutrient utilization rate were 22.9% to 13.4%, 11.2% to 9.6% and 17.5% to 12.1%. [Conclusion] Adhesive controlled release fertilizer could significantly improve the nutrient utilization efficiency and yield of maize.
