摘　　要：为探索高分子化合物与复合肥互作对小麦生长以及产量的影响。本研究将高分子材料与肥料复合,并采用大田小区模拟对比的方法,通过观测植株株高、叶面积、叶绿素含量、干物质量以及产量变化,分析和评价研发的高分子肥料的应用效果。结果显示：施用材料的处理PNPK比其他处理提高株高达4.43%-25.09%,叶面积指数最大值能提高33.61%-95.6%,提高叶绿素含量6.69%-25.07%,施用改性高分子肥料有利于小麦的生长;相同营养条件下施用高分子材料能提高小麦各部位干物质积累,同时能提高产量10.08%-24.71%。因此,在小麦种植过程中施用改性高分子肥料PNPK能显著提高小麦株高、叶面积、叶绿素以及干物质积累,有利于小麦增产。Abstract： In order to explore the effects of polymer materials compound and compound fertilizer on wheat growth and yield, the polymer materials and fertilizers were combined in this paper, and the method of field plot simulation was used to analyze and evaluate the application effect of high molecular fertilizer on the development of the high, leaf area, chlorophyll content, dry matter and yield. The results showed that the plant height under the treatment of PNPK increased 4.43 % - 25.09 % , the leaf area index could increase 33.61% - 95.6 %, and chlorophyll content increased 6.69 % - 25.07 %, indicating that the application of modified high molecular fertilizer could be beneficial to wheat growth; Using the molecular materials, the accumulation of dry matter in wheat could be increased, and its yield was increased 10.08 % -24.71%. Therefore, in the process of wheat planting, the use of modified high polymer PNPK could significantly improve the height, leaf area, chlorophyll and dry matter accumulation of wheat plant, which was conducive to wheat production.
