摘要:

黄枝油杉属珍稀濒危植物,树形高大,采种困难,母树开花结实少,种子发芽率低,繁殖速度慢。采用扦插育苗,方法简便易行,繁殖速度快。为此,针对与黄枝油杉扦插育苗成活、生长密切相关的插穗粗度、ABT生根粉浓度和施肥种类三大因素,分别进行对比试验。结果表明:插穗茎粗0.70 cm用150 mg/L ABT生根粉溶液处理的平均成活率达95.6%; 扦插成活后施用粪肥+尿素(配比为100:0.4)的混合肥苗木生长健壮,平均抽梢长达30.8 cm。方差分析和多重比较分析结果表明,插穗粗度、ABT生根粉浓度和肥料种类对黄枝油杉扦插苗木的生长影响极大。

Abstract:

Keteleeria calcarea is one of the rare and endangered tree species. The stem is tall and thick. Since the flowering and seed setting rate in fruit-bearing shoots are few,seed collecting is very difficult. Moreover,neither the germination percentage of seeds nor the propagation rate is high. In this research,for its convenient and rapid propagation,cuttage seedling was conducted through difference treatments by comparison analysis respectively. Three factors,including rooting agent,fertilization condition and cutting diameter on seedlings raising and growth of K.calcarea,which is close related with survival rate,was discussed. The result shows: treated with ABT rooting powder at concentration of 150 mg/L,while cutting diameter is 0.70 cm,the average percentage of survival represents 95.6%. After that,manure and carbamide(manure:carbamide=100:0.4)are optimal fertilizer on cutting to meet the growth requirements of robust shoots. The average shoot growth is up to 30.8 cm.
