茶园套种降香黄檀效应的初步研究

根据降香黄檀和茶树的生物学、生态学特性及华安光照人林场的生态环境条件,采取林+茶栽培模式,开展了茶园不同密度套种降香黄檀试验。初步结果表明:降香黄檀造林平均成活率和保存率均达96%以上;2.5年生时,平均树高4.38m,平均地径5.16 cm,但不同坡向生长量差异极显著;降香黄檀抗冻能力强,表现出较好的适应性和速生性。套种密度为450~600株.hm-2比较适宜,不仅改善了茶园的生态环境,提高了茶叶产量和品质,而且使茶园的经济效益显著提高。

Preliminary Study on the Effect of Planting Dalbergia odorifera in Tea Garden

Based on biological property and ecological character of Dalbergia odorifera,and tea and Guangzhaoren Forest Farm entironment,the paper conducted the experiment of interplanting D.odorifera with different densities in tea gardern by cultivation mode of "forest + tea".The preliminary results were as follows:D.odorifera average survival rate and conservation rate reached 96% and more,two years and five months old tree's average height was 4.38 cm,average ground diameter was 5.16 cm,but there were significant difference in trees growth with different slope direction.The trees had high ability of freeze proof,and the adaptability and fast-growing characters of D.odorifera appeared.Selection of the density of trees of 450～600·hm-2 was proper relatively ,it not only improved the ecological environment of tea garden and increased tea yield and tea quality,but also improved the economical benefits of the tea garden.
