油茶黑膜覆盖栽培技术研究

Study on Cultivation Techniques of Black Film Covering in Camellia oleifera

[目的]研究油茶黑膜覆盖栽培技术以提高造林效果。[方法]研究黑膜覆盖和不覆膜2种处理对油茶苗木成活率、地径、苗高、分枝数、新梢长度的影响,并采用入户调查的方式调查油茶种植户的收入和成本。[结果]黑膜覆盖与对照相比,苗木成活率提高了5.94个百分点,苗木平均高增幅为13.06%,苗木地径增幅为17.31%,平均分枝数增幅为13.55%,新梢平均长度增幅为17.06%。[结论]黑膜覆盖能显著提高油茶苗生长量和存活率,促进油茶苗木的生长;与未覆膜相比,黑膜覆盖在造林成活率、苗高、地径、分枝数及新梢长度等方面均达到显著水平。

[ Objective ] Cultivation techniques of black film covering in Camellia oleifera were studied for improving afforestation effect. [ Method ] The influence of black film covering in Camellia oleifera and control treatments on the survival rate, seedling height and diameter at ground, branch number, new tips length were studied. And the income and cost of planting households were investigated. [ Result] Compared with control group, the survival rate of seedlings increased 5.94 percentage points, seedling height increased 13.06% , ground diameter increased 17.31% , branch number increased 13.55% , new tips length increased 17.06%. [ Conclusion] It has significant effect that black film covering could improve the growth and survival rate of CameUia oleifera ; there have significaut differences in survival ratio of forestation, seedling height, ground diameter, branch number, new tips length and so on between black film covering and non-film.
