【摘要】 为保证新造油茶林营养的及时补充,促进树体生长,对油茶新造林进行了追肥试验,结果表明:施肥能显著促进新造林植株生长,提高叶片叶绿素和可溶性糖的含量;施肥处理的抽新梢率和平均新梢数分别为83.3%和3.8,分别比对照高31.6%和47.0%;施肥处理叶片的叶绿素和可溶性糖含量显著高于对照,分别达5.43 mg/g和39.98 mg/g;不同品种油茶苗造林后施肥效果不同,其中‘湘林67’的施肥生长效果最好;施肥有利于促进容器苗新梢的生长,增加新梢叶片叶绿素及内含物的含量,但对裸根苗造林植株的生长有一定的抑制作用。更多还原

【Abstract】 In order to ensuring nutrition for new plantation of Oil-tea Camellia in time,topdressing test of new plantation of Oil-tea Camellia was conducted. The result showed that topdressing markedly promoted growth and increased the content of chlorophyll and soluble saccharide of leaf. The shoot growth rate and average shoot number of topdressing was 83. 3% and 3. 8 respectively,more 31. 6% and 47. 0% than contrast. The content of chlorophyll and soluble saccharide of leaf of topdressing markedly exceeded that of contrast,which reached 5. 43 mg / g and 39. 98 mg / g respectively. Different breeds of afforestation seedling had different topdressing effect,and the growth effect of XL67 was the best. Topdressing was beneficial to promote growth of container seedling and increase the content of chlorophyll and inclusion of leaf,but it restrained the growth of bare-rooted seedling.更多还原
