海藻酸复合肥对叶菜类蔬菜产量的影响

Effect of Alginic Acid Compound Fertilizer on Yield of Leafy Vegetables

为探索同一配方下的海藻酸复合肥与普通复合肥对叶菜类蔬菜产量的影响,以结球甘蓝、大白菜、生菜为研究对象,开展了肥效对比试验。试验结果表明,海藻酸复合肥对叶菜类蔬菜产量的提高均有一定的促进作用,增产幅度在1.1%~25.0%,增产量在375-10500 kg/hm^2,增收在1350-52350元/hm^2,说明在普通复合肥的基础上添加一定量的海藻酸对叶菜类蔬菜具有一定的增产效果。

In order to explore the effect of alginic acid compound fertilizer and common compound fertilizer on the yield of leafy vegetables under the same formula,the comparative experiment of fertilizer efficiency is carried out with cabbage,Chinese cabbage and lettuce as research objects.Experimental results show that alginic acid compound fertilizer has a certain promoting effect on the yield of leafy vegetables.The increase range in yield is 1.1%〜25.0%,the yield increases by 375〜10500 kg/hm^2,and the income increases by 1350〜52350 yuan/hm^2,indicating that adding a certain amount of alginic acid to the common compound fertilizer has a certain yield increase effect on leafy vegetables.
