前言据說当施行扦插繁殖时,發根困难的植物,是由于插穗中存在着有阻碍發根的物質,为了除去这种物質,把插穗用过錳酸鉀(Kmno4)处理。茶树扦插后發根的难易,原因是很多的,这个試驗底目的,是要証明过錳酸钾有沒有促進發根的效果。供扦插用的土壤,一般都用赤土,但連續使用2—3年后,虽能同样發根,其后的生育却很不好,所以普通到了第3年,都須換用新土,如能把換土手續省掉,是非常经济的,因此又做土壤試 Preface It is said that when cutting propagation, plants with difficult-to-root hair are caused by the presence of substances that impede hair roots in the cuttings. To remove this material, the cuttings are treated with potassium permanganate (Kmno4). After the cutting of tea tree root hair is difficult, for many reasons, the purpose of this experiment is to prove that potassium permanganate did not promote hair root effect. Soil for cutting purposes is generally terracotta, but after 2-3 years of continuous use, although the same rooting can occur, subsequent fertility is very poor. Therefore, in the 3rd year of ordinary use, it must be replaced with new soil such as Can save replacement procedures, it is very economical, so do the soil test
