为探究不同增效剂及其组合在叶菜上的喷施效果,以黄腐酸钾(增效剂1)、植物免疫蛋白(增效剂2)、天然环保植物生长调节剂(增效剂3)为试验对象,开展了甜菜盆栽试验。结果表明:叶面喷施增效剂对甜菜株高有促进作用;在整个生长期间,3种增效剂组合喷施处理的叶片数最多;不同增效剂处理下的叶片相对叶绿素含量(SPAD值)差异基本不明显。从叶面积、株高、地上部鲜质量以及长势均匀度考虑,喷施增效剂3较合适;从叶片数和SPAD值分析,增效剂2+增效剂3组合、增效剂1+增效剂2+增效剂3组合较为合适。
In order to explore the spraying effect of different synergists and their combinations on leafy vegetables, the pot experiment on sugarbeet is carried out with potassium fulvic acid (synergist 1), plant immune protein (synergist 2) and natural environmental protection plant growth regulator (synergist 3) as the experimental objects. The results show that foliar spraying synergist is able to promote the plant height of sugarbeet. During the whole growth period, the treatment of three synergists combination has the most the number of leaves. There is no significant difference in leaf relative chlorophyll content (SPAD value) under different synergist treatments. Considering leaf area, plant height, aboveground fresh weight and growth uniformity, synergist 3 is the most suitable one. From the growth uniformity and leaf number analysis, synergist 1 plus synergist 3 combination, synergist 1 plus synergist 2 plus synergist 3 combination are more suitable combination.
