杜仲密植栽培与常规栽培的产量对比分析

Comparative Analysis on Yield of Dense Planting Cultivation and Normal Cultivation for Eucommia ulmoides Oliv.

摘要:

笔者在对杜仲密植栽培与常规栽培高生长、地径生长、胸径生长及树干性状进行对比试验研究的基础上,又对杜仲皮的产量进行了对比分析,结果表明:密植栽培与常规栽培的产量之间存在明显差异.密植栽培的杜仲皮每67 m2的产量在111.0～134.5 kg之间,平均为122.8 kg,常规栽培的产量在40.9～44.2 kg之间,平均为42.6 kg,密植栽培的平均产量是常规栽培的2.8倍.

Abstract:

The authors carry out comparing analysis on yield of bark of Eucommia ulmoides Oliv.based on comparing test study on growth of height,ground diameter,DBH and tree trunk feature of dense planting cultivation and normal cultivation for Eucommia ulmoides Oliv.,the result show that the yield between the dense planting cultivation and normal cultivation exist obvious difference.The bark yield is between 111.0 ~134.5 kg with average yield by 122.8 kg from dense planting cultivation,and the yield is between 40.9~4...
