高分子化合物对小麦出苗及生长的影响

Effects of Macromolecular Compounds on Emergence and Growth of Wheat

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。

Aim of this study was to explore effects of macromolecular material on wheat at seedling stage. Firstly, the macromolecular materials were modified; Second, mixed fertilizer with macromolecular materials using the overall method. And using the method of pot simulation, effect of applying modified macromolecular materials was tested by observing the plant growth index. Results showed that modified macromolecular materials that meet the require- ments of the 24 modified processing were P, PO, HO. Compared with the control, the effect of modified macromolec- ular materials on the seedling emergence rate was not significant, which improved the seedling emergence rate by 3.33%. Compared with the control, the treatment of maeromolecular material and composite fertilizer improved the plant height by 18.77%, and dry matter by 10.45%. Therefore, mixed fertilizer with macromolecular materials could increase wheat seedling height, dry weight, which was conducive to the growth of wheat seedling.
