生菜喷施微量元素水溶肥料肥效试验研究

Study of Trace Elements Water-soluble Fertilizers on Lettuce

[目的]测试微量元素水溶肥料对生菜作物生长的影响。[方法]对生菜叶面喷施微量元素水溶肥小区试验,测定生菜株高、产量等性状。[结果]喷施凌创微量元素水溶肥促进生菜生长,对增加单株高和单株重有一定的促进作用,从而提高生菜产量,经济产量达44 520 kg/hm^2,较空白对照增产率达10.96%,增产增效5 835元/hm^2,产投比达5,效益可观。[结论]叶面喷施微量元素水溶肥料可以促进生菜生长,实现增产增收。

[Objective] To explore the effect of trace elements water-soluble fertilizers on planting of lettuce. [Method] Lettuce were treated with fertilizers by foliar dressing, then plant height, yield and other traits were measured. [Result] Trace elements water-soluble fertilizers could improve planting of lettuce and increase the yield. After giving this trace elements fertilizer,the yield were 44 520 kg/hm^2 which had increased by 10.96% than blank control. Economic efficiency were 4 530 RMB/hm^2. Input-output ratio were 1.83. [Conclusion] Trace elements water-soluble fertilizers could improve lettuce and increase efficiency.
