落叶经济林黄花梨林下套种油茶试验初报

采用2 a生油茶嫁接苗在黄花梨盛果期（树龄15 a）林下进行不同方式套种（株间、行间、交叉点套种）造林对比试验，对造林后6 a油茶生长状况、结实量和黄花梨产量、质量进行调查。结果表明，以交叉点套种油茶单株效果最好，平均冠幅达141.0 cm，平均保存率91.5%，油茶籽产量达3.86 kg·株-1；交叉点套种和行间套种油茶对黄花梨产量的影响较小，单株产量、优质果率与对照（不套种）差异不显著；株间套种油茶对黄花梨产量的影响较大，单株产量比对照低20.4%，优质果率比对照低23.3%。

Interplanting Camellia oleifera under Deciduous forest of Huanghua Pear

Different interplanting methods (inter-plant, inter-row and intersection) using 2 a Camellia oleifera grafted seedling interplanted with 15 a Huanghua pear tree were carried out, then the growth and coning quantity of 6 a plants of C. oleifera, the production and quality of Huanghua pear were investigated. The results showed that: intersection planting was best for oil-tea, average crown breadth was upto 141.0 cm, the average survival rate was 91.5%, and the average yield of C. oleifera seeds was 3.86 kg per plant; there was little effect on production of chrysanthemum pear by intersection and inter-row planting; while, inter-planting had great effect on production of chrysanthemum pear, the production per plant and high grade fruit rate of chrysanthemum pear were lower 20.4% and 23.3% than control, respectively.
