摘  要:
针对于油茶幼林初期只投入无产出的实际问题,在油茶新造林开展套种药食同源植物平卧菊三七的试验研究,试验结果表明:油茶幼林套种平卧菊三七后,通过日常的精耕细作,使土壤的肥力和结构都得到很好的改善,全氮和水解氮的含量分别降低30.1%和21.2%;全磷降低10%、有效磷增加9.6%;全钾增加14.0%、速效钾增加14.3%;有机质增加22.4%。土壤容重减少8.6%,总孔隙度增加19.8%,含水量增加32.3%。同时不会影响油茶的生长,既为油茶幼树的生长发育创造了良好环境,又能降低油茶幼林的养护成本。

摘  要:
According to high input and low output in the young plantation of Camellia oleifera, it was experimented on the interplanting Gynura procumbens in the new plantation of C. oleifera. The results showed that interplantion had a significant improving effect on soil fertility and properties from intensive cultivation. Total N and hydrolytic N contents decreased by30.1% and 21.2%, respectively; total P content decreased by 10%, available P content increased by 9.6%; total K content increased by 14.0%, available K content increased by 14.3%; organic matter content increased by 22.4%, soil bulk density decreased by 8.6%, total porosity increased by 19.8%, moisture content increased by 32.3%. At the same time, interplantion does not affect the growth of C. oleifera. Accordingly, interplantion creates good environment for the growth of C. oleifera trees, as well as reduces the maintenance cost of the new plantation of C. oleifera.
