在植物生理实验中有“刺激物质对生长的影响”一部分,我们曾做了以生长刺激物来影响植物扦插生根。于实验时希望选用的植物能够生根快同时也具有一定的经济价值;因此探用了正木(大叶黄杨Fvonymus japonica)做材料。正木的枝条是选用当年生的成熟枝,剪成长约15厘米插穗,生长刺激物质采用0.05％2,4-D药效范围较广的粉剂(2,4-D溶于酒精后再倒入滑石粉中)。抒插时先将剪好枝条的基部以水湿润后醮2,4-D粉剂,再插于温室冷床 In plant physiology experiments there is “a part that stimulates the growth of substances”, and we have done with growth stimulants to influence plant cutting rooting. In the experiment, we hope that the plants we choose can root quickly and have certain economic value at the same time. Therefore we explored the material of Fvonymus japonica. Masaki’s branches are made of mature branches that year, cut into about 15 cm cuttings, growth stimulating substances 0.05% 2,4-D efficacy of a wide range of powder (2,4-D dissolved in alcohol and then into the talc Powder). To express the first cut will be cut when the base of the water moist 醮 2,4-D powder, and then inserted in the greenhouse cooling bed
