摘要
从植物生长环境中的微量元素调控着手,研究了一种新型植物生长促进剂的理化性质,探讨了该促进剂的生物学机理,比较了使用促进剂与未使用促进剂两种处理对叶类蔬菜、根类蔬菜和果实类蔬菜生物产量和品质,尤其是其对蔬菜叶片硝酸盐含量的影响。盆栽实验表明:该促进剂含有多种植物生长所必须的微量元素硫、铁、铝、锰、镁、钛、锌、钾、硼、钼、钙、铜等,施用该促进剂后,有利于蔬菜发芽生长,提高蔬菜叶绿素含量和果实含糖量,降低蔬菜硝酸盐含量。
Considering the control of trace elements in the plant growth environment, the physicochemical properties of a new kind of plant growth regulator were studied. The biology mechanism was discussed while the effect of the tested plant growth regulator on vegetables＇ yield and quality was also studied. The result shows that this tested plant growth regulator contains many trace elements ： S, Fe, Al, Mn, Mg, Ti, Zn, K, B, Mo, Ca, Cu, etc. After application of the regulator, it has beneficial effects on vegetables growth and sprouting, vegetables chlorophyll content, and reduction of the nitrate content of vegetables.
