我们于1972年从引种扦插油橄榄开始,又对水杉、雪松、日本金松、罗汉松、糖槭、桂花、含笑花、小果油茶、南岭黄檀等树种进行了扦插繁殖试验。初步摸出了扦插生根率与插穗树种、品种、母树年龄、枝条年龄、部位、插壤、生长激素、扦插深度、扦插季节、温度、湿度(薄膜空间湿度、插壤含水量)、光照等之间的相互关系,同时初步掌握了促进某些难生根树种生根的方法。一、插穗的选择(一)插穗选择的一般原则插德品质的好坏对发根影响较大,因此繁殖用的枝条应选取母树生长旺盛,无病虫害,枝条健壮、充实、叶芽饱满,1年生半木质化枝条。如果是以获得果实为目的的经济林,应选优良母树上的结果枝,则可丰产和提早结果;如果是以获得木材为目的的用材林,应选优良母树的1年生萌发枝,则可速生丰产,林相整齐。
We started from the introduction of cutting olive in 1972, and cuttings of Metasequoia, cedar, Japanese pine, Podocarpon, sweet maple, sweet-scented osmanthus, small camellia, The results showed that the rooting rate of cuttings was positively correlated with the rooting rate of cuttings and the species, species, age of mother tree, branch age, location of cuttings, growth hormone, cutting depth, cutting season, temperature, humidity (film space humidity, Between the mutual relations, at the same time initially mastered the promotion of some difficult rooting methods. First, the choice of cuttings (A) cuttings general principles of choice Plug quality is good or bad on the hair root greater impact, so breeding branches should be selected strong growth of the mother tree, no pests, robust branches, full, leaf bud full, 1 year Half-lignified branches. If it is for the purpose of obtaining economic fruit forest, should be selected on the results of the fine tree branches, you can yield and early results; if it is timber for the purpose of obtaining timber, should choose a good one-year-old female tree branches, then fast-bumper , Neat forest phase.
