摘要
[目的]明确黑膜和其他材料共同覆盖对油茶产量性状的影响。[方法]选择黑膜、谷壳、木屑和遮阳网材料,在3种不同立地,按照裂区试验设计进行试验,调查油茶落果及其他产量性状。[结果]在红壤立地条件下黑膜上面覆盖谷壳、未垦复立地条件下木屑上面覆盖黑膜及在砂砾立地条件下黑膜上面覆盖木屑落果较少;在红壤区和未垦复区谷壳上面覆盖黑膜,砂砾区黑膜上面覆盖遮阳网单果较重;在红壤区木屑上面覆盖黑膜,未垦复区黑膜上面覆盖木屑及砂砾区谷壳上面覆盖黑膜平均籽较重;在红壤区谷壳上面覆盖黑膜,未垦复区黑膜上面覆盖谷壳及在砂砾区直接覆盖黑膜茶果鲜出籽率较高;在红壤区覆盖黑膜、未垦复区和砂砾区木屑上面覆盖黑膜茶籽含水率较低,出仁率较高;在红壤区黑膜上面覆盖遮阳网,未垦复区木屑上面覆盖黑膜及砂砾区黑膜上面覆盖木屑仁出油率较高。[结论]较为有利的覆盖方法是在红壤区黑膜上面覆盖谷壳,在未垦复区木屑上面覆盖黑膜,在砂砾区黑膜上面覆盖木屑。
[Objective]To investigate the effects of black film and different material combinations on yield characteristics of Camellia oleifera. [Method]Black film,chaffs,wood chips and shade net materials were selected,the experiment was carried out in three different sites according to the test design of the split zone,then investigated the fruit drop rate and other related indexes.[Result]The fruit drop rate was lowest when covered with black film under husks in red soil and gravel region,black film above wood chips in unreclaimed region;the single fruit was heavier when covered with black film above husks in red soil and unreclaimed region,black film under shade net in gravel region;the average seed was heavier when covered with black film above wood chips in red soil region,black film under wood chips in unreclaimed region,black film above chaffs in gravel region;the fresh seed yield was higher when covered with black film above chaffs in red soil region,black film under chaffs in unreclaimed region and black film in gravel region;the seed moisture content was lower and kernel rate was higher when covered with black film in red soil region and black film above wood chips in unreclaimed and gravel region;the oil content was higher when covered with black film under shade net in the red soil region,black film above wood chips in unreclaimed region,black film under wood chips in gravel region. [Conclusion]More favorable coverage is covered with black film above husk in the red soil region,black film above wood chips in the undeveloped,black film under wood chips in the gravel area.
