三种植物活性剂对菜心产量的影响

Effects of three plant activating agents on production of Brassica chinensis

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。

Three plain activating agents,OPAL HA202,Baode and soil improving agent were sprayed on soil surface. It was shown that three plant activating agents sprayed on soil surface had different yield enhancing effects on Brassica chineiisis: (1 )The roots of Brassica chinensis grew better and the mam stem was bigger than the control; (2)The plant activating agents could induce more assimilation products distributed to the leaves, and more dry matters were accumulated. All results above led to the increase of the production. The Brassica chinensis production sprayed by OPAL HA202 was 41 .33% higher than that of control and best combining effects,25.06% higher than control by Baode. The first reached extremely significant level, the second reached significant level.
