不同育苗基质对油茶芽砧嫁接苗生长的影响

Effects of Different Nursery Substrates on the Growth of Grafting Plants of Oil Camellia

通过对几种育苗基质对油茶芽砧苗成活率、苗高、地径以及根系等生长指标对比分析的结果表明,在4个基质配比中,1 a生芽砧嫁接苗以油茶轻基质容器苗保存率、树高和地径表现为最大,分别为82.2%,32.1 cm和0.31cm;苗木根系以2 a生大田裸根苗主根为最长,为13.3 cm,根茎比最大,为0.50,适宜油茶造林后后期生长。因此培育1 a生油茶苗以油茶轻基质为最佳选择,培育2 a生苗应该选择大田育苗。

In this paper, studies were made of the effects of several substrates on the survival rate, height,ground diameter and root system and other growth indicators of Camellia oleifera seedlings. The resultsshowed that among 4 matrix proportions, the average survival rate of annual Camellia oleifera seedlings grafting in light matrix container was 82.2%, the average height was 32. 1 cm, average diameter was 0. 32 cm, being the 13.3 cm. The ratio largest. The seedling taproot of biennial field raising seedlings was the longest, being of roots to shoots was the maximum, being 0. 50. That was suitable for the later periodgrowth of Camellia oleifera after afforestation. Therefore for cultivating 1-year-old seedlings the camellia light matrix was the best choice, cultivating biennial seedlings should select the field nursery.
