目前,落羽杉的种源十分缺乏,扦插繁殖是生产苗木的主要途径。为探索快速育苗技术,我们于1975年春夏两季用异龄母树上的枝段和幼树不同部位的枝段作了扦插试验。同时,用较大母树上的不同枝段及嫁接植株上的当年嫩枝插条进行了生长素处理。现将试验情况及结果报告如下: 一、试验材科和方法 (一)春插部分 1.一年生实生苗不同部位枝段的扦插:将截干条自基部往上分成基段、二段、三段、四段、梢段,分别扦插。
At present, the species of Taxodium distichum is very scarce, cutting propagation is the main way to produce seedlings. In order to explore the rapid seedling technology, in the spring and summer of 1975, we used the branch of Anemarrhena asparagus and the branches of different parts of the young tree to make cutting experiments. At the same time, the auxin treatment was carried out on the different branches of the larger mother tree and the current year’s shoot cuttings on the grafted plants. Now the test results and the results are reported as follows: First, the test materials and methods (A) Chun inserted part of the annual seedlings in different parts of the branch of the cuttings: the cut stem from the base up into the base section, two, three Section, four sections, shoot section, respectively, cuttings.
