摘要
为探索硝基复合肥中镁与硼复配对作物生长及产量的影响,以辣椒为试验对象,开展了盆栽试验。结果表明:在硝硫基复合肥(15-15-15)中添加质量分数5.0%一水硫酸镁的基础上,再分别添加质量分数0.5%、1.0%、1.5%、2.0%、2.5%硼砂的处理与对照处理相比,辣椒的增产率分别为7.44%、11.70%、21.12%;较高的硼砂添加量对辣椒地上部和地下部的生长有一定的抑制作用。与对照处理相比,在硝硫基复合肥中添加质量分数5.0%一水硫酸镁处理的辣椒株高、茎粗、地上部鲜质量无优势,且地下部干质量出现下降,表明一水硫酸镁添加量较高对辣椒根系、植株生长具有一定的抑制作用,但添加一定量的硼砂后,可在一定程度上逆转高含量硫酸镁对植株生长的抑制作用。
In order to explore the effects of magnesium and boron in nitro compound fertilizer on crop growth and yield, a pot experiment is carried out with pepper as the experimental object. The results show that on the basis of adding 5.0% magnesium sulfate monohydrate by mass fraction to nitrate sulfur based compound fertilizer(15-15-15), adding 0.5%, 1.0%, 1.5%, 2.0% and 2.5% borax by mass fraction can improve the yield of pepper. Compared with the control, the yield increase rates are 7.44%, 11.70% and 21.12% respectively. The higher amount of borax has a certain inhibitory effect on the growth of aboveground and underground parts of pepper. Compared with the control, the pepper treated with only 5.0% magnesium sulfate monohydrate by mass fraction in nitrate sulfur based compound fertilizer has no advantages in plant height, stem diameter and aboveground fresh weight, and the dry weight of underground decreases, indicating that the high addition of magnesium sulfate monohydrate has a certain inhibitory effect on the root and plant growth of pepper, but after adding a certain amount of borax, the inhibitory effect of high content of magnesium sulfate on plant growth can be reversed to a certain extent.
