双微生物液对玉米苗期生长发育的影响

Effect of Double Microorganism Liquid on the Maize Growth during Seedling Stage

壮苗是作物取得最终高产的物质基础。以玉米为对象,研究双微生物液对培育壮苗的效果及对玉米苗期抗旱性的影响。试验结果表明:经双微生物液浸种处理后,玉米苗期根系及茎叶的生长发育均得到显著提高,表现在双微生物液提高了玉米苗期的总干质量,培育了壮苗,为玉米后期的生长发育及最终产量的形成奠定了物质基础。生物菌肥的施用可以达到较为明显的促进效果,但施肥时要注意平衡施肥,不要单一施用某一种肥料。

Strong seedling is the ultimate material basis for crop high yields.The effect of double microorganism liquid on raising strong seedlings and its drought resistance was studied with maize as the study subject.The experiment results show that there is a dramatic increase in the growth of maize root system and stem leaf after seed soaking with double microorganism liquid with the result that the dry weight of maize during seedling stage increases,generating strong seedlings and laying material foundations for maize ultimate high yields.The applications of bacterial manure can substantially stimulate maize growth but attention should be paid on balanced fertilizations.
