摘要

对永丰县油茶采穗辅不同施肥措施下穗条产量与质量进行调查。结果表明:1)油茶采穗圃进行施肥处理后,单株穗条数量较CK提高10.74%~36.79%,穗条长度增长4.85%~23.36%,穗条直径提高10.13%~32.16%,单穗芽数增加11.37%~25.76%;施肥后的增产效果显著;2)油茶采穗圃采取全年施肥2次,每年11月施油茶专用肥0.15 kg/株,并施用N、P、K元素配方为N1P3K3的配方肥0.3 kg/株,次年2月下旬施尿素0.1 kg/株,穗条产量可获得最大收益,建议推广施用。%The yield of scion cuttings and its quality of Camellia oleifera cutting orchard under different fertilization measures in Yongfeng County, Jiangxi province were investigated. The results showed that:1) after fertilization treatment on C. oleifera cutting orchard, the number of plant cuttings improved by 10.74%~ 36.79% compared with CK, cutting lengths increased 4.85%~23.36%, cuttings diameter raised 10.13%~32.16%, number of single spike buds increased 25.76% ~ 11.37%; the yield increased significantly after fertilization; 2) adopting fertilization twice a year, with specialty fertilizer 0.15 kg/plant in November, and applied the recipe fertilization of N1P3K3 with N, P, K elements formula 0.3 kg/plant, with urea 0.1 kg/plan in late February next year, cuttings can get maximum yield, it is recommended to promote the administration.
