用OPAL HA202、保得接种剂、土壤改良剂3种植物活性剂施于菜心地的表上,结果表明,3种活性剂,对菜心均有不同程度的增产效果。其根部比对照的发达,主茎粗壮高大,特别是同化产物向叶中分配增加明显,于物质积累多。其中以OPAL HA202处理后的菜心综合效果最佳,其产量比对照增加41.33％,达极显著水平;其次为保得接种剂,其产量比对照增加25.06％,达显著水平。 With OPAL HA202, Paul inoculant, soil conditioner three kinds of plant active agent applied to the cabbage heart table, the results show that the three active agents, cabbage have different levels of yield. Its roots than the developed, the main stout stout, especially the assimilation product increased significantly to the leaf distribution, the accumulation of material and more. The results showed that the yield of Brassica parachinensis OPAL HA202 was the best, and its yield was 41.33% higher than that of the control. The yield was significantly higher than that of the control.
