摘要: 选用安徽省、河南省、恩施土家族苗族自治州、保康县4个地方豆腐树(Premna microphylla Turcz.)种苗,分析了3种不同密度栽培试验(株行距分别为20 cm×80 cm、30 cm×80 cm、40 cm×100 cm)对豆腐树形态指标和产量的影响。结果表明,不同采挖地品种的产量和果胶含量差异明显,恩施土家族苗族自治州树种鲜叶产量最高,平均每株每年鲜叶产量为2 500 g;安徽省树种果胶含量最高,果胶含量为35.25%。不同种植密度对产量有明显影响,30 cm×80 cm的株行距最有利于豆腐树的生长,平均每株每年鲜叶产量为2 269 g。

关键词: 豆腐树(Premna microphylla Turcz.), 种植密度, 产量

Abstract: To explore the effects of different planting density on morphology index and yield of Premna microphylla Turcz.,selected fourgermchitscoming from Anhui province,Henan province,Enshi Tujia and Miao Autonomous Prefecture,Baokang county of Hubei province,carrying on 3 kinds of different density cultivation experiment (The plant row spacing were 20cm×80cm,30cm×80cm,40cm×100cm).The results showed that a significant difference in yield and pectin content of Premna microphylla Turcz.,the yield of fresh leaf coming from Enshi Tujia and Miao Autonomous Prefecture tree was highest,the average yield of fresh leaf of each tree was 2500g every year.The pectin content coming from Anhui province tree was highest,the average pectin content per kilogram of leaves was 35.25%.Different planting density had obvious effect on the yield.The plant row spacing of 30cm×80cm was the best for the growth of Premna microphylla Turcz.The average annual fresh leaf yield per plant was 2269g.

Key words: Premna microphylla Turcz., planting density, yield
