为了探索高分子材料对小麦苗期的影响,该文首先对高分子材料进行了改性,其次应用整体法将复合肥同改性材料混合,并采用盆栽模拟对比的方法,通过观测植株生长指标试验改性高分子材料的应用效果。结果表明:在24个改性处理中符合要求的改性材料有P、PO、HO;改性高分子材料处理与对照相比,对小麦出苗率的影响差异不显著;但可提高出苗率3.33%;与对照相比,高分子材料与复合肥混施中处理可提升株高18.77%,干重提高达10.45%。因此,高分子材料及改性材料与肥料混施均能提高小麦苗期株高、干重,有利于小麦苗期生长。
In order to explore the impact of polymer materials on wheat seedling stage, the paper first modified the polymer materials, followed by the application of the overall method of compound fertilizer with modified materials, and the use of pots simulation comparison, through the observation of plant growth index Test the effect of modified polymer materials. The results showed that the modified materials that meet the requirements of the 24 modified treatments were P, PO and HO. The effect of modified polymeric materials on the emergence rate of wheat was not significant when compared with the control, but the germination rate was improved 3.33 %. Compared with the control, the treatment of polymer materials and compound fertilizer increased the plant height by 18.77% and the dry weight increased by 10.45%. Therefore, the polymer materials and modified materials mixed with fertilizers can improve wheat seedling height, dry weight, is conducive to wheat seedling growth.
