三十烷醇是一种新型广谱性植物生长调节剂,在农作物和疏菜上已广为利用,近年来林业也在苗圃育苗上对当年生苗木进行叶面喷雾,效果显著。为了探讨用三十烷醇浸泡杨插条的促进作用,我们今年春季在尚志县苇河林场西工段,对小×黑剪穗进行不同浓度的浸泡育苗插条试验,经调查苗高和地径生长均达到显著和极显著,提高了出穗率,增加了经济效益,现将试验结果整理如下: Triacontanol is a new broad-spectrum plant growth regulator, which has been widely used in crops and vegetables. In recent years, tributyl alcohol has also been used as a leaf sprayer in seedling nurseries. In order to explore the promotion effect of triacontanol-soaked poplar, we tested the immersion nursery cuttings with different concentrations in the western section of Weihe Forest Farm in Shangzhi County this spring. After investigation, the height and diameter The growth has reached a significant and very significant, increased out of the spike rate, increased economic efficiency, the test results are summarized as follows:
