夏玉米用ＡＢＴ６号生根粉浸种，其最适浓度为２５ｍｌ／Ｌ，用该浓度ＡＢＴ６号浸种处理，其播种至出苗时间短、出苗率高；拔节期叶数及根条数最多；单株绿叶面积、地上部干重最高；穗行数、穗粒数最多，千粒重较高；但经方差分析，这些差异均未达显著水平。小区产量也以２５ｍｌ／Ｌ处理的最高，与其它处理相比，差异达极显著水平，单产较清水对照增加９．８７％。 Summer maize was soaked with ABT6 rooting powder, its optimum concentration was 25ml / L. With this concentration of ABT6 seed soaking, its seedling time was short and the rate of emergence was high; the number of leaf and the number of root in jointing stage was the most; Area, the highest dry weight above the ground; spike number of rows, grain number per spike, high 1000 grain weight; but by variance analysis, these differences were not significant. The plot yield was also highest at 25ml / L. Compared with other treatments, the difference reached an extremely significant level, and the yield per unit area increased by 9.87% compared with the control.
