大叶杨黄(Euonymus japonjcus Thumb.)卫矛科常绿灌木。在北方多做绿篱栽植或修整成球形,广泛应用于园林绿地。但其枝梢年生长量大,植株下部容易光秃.不仅每年需花费大量的人力修剪,而且影响观赏效果。据报道,PP_(333)做为一种新型植物生长调节剂,对许多植物种类的生长都有较强的抑制作用,可明显地减少延长枝的长度,促进当年生枝的侧芽发育,并可缩短节间长制,增加叶片厚度而较少副作用。本试验拟通过应用生长凋节剂PP_(333),对大叶黄杨进行处理,以减少枝梢的生长
Euonymus japonjcus Thumb. Glaucous shrubs. In the north to do more hedging planting or dressing into a sphere, widely used in landscaping. However, the annual shoot growth is large, and the lower part of the plant is easily bald, which requires not only manpower pruning but also ornamental effects. It has been reported that PP 333 as a new plant growth regulator has a strong inhibitory effect on the growth of many plant species and can significantly reduce the length of the branches and promote the growth of lateral buds of the branches of the current year, Internode length, increased leaf thickness with fewer side effects. In this experiment, the application of growth witching agent PP_ (333), to deal with the Euonymus japonicus to reduce the growth of shoots
