摘要
通过对衰败毛竹低产林采取不同的改造措施 ,分析改造后毛竹林 9个生长指标的变化 ,结果表明 :除鞭径、鞭节数及单位面积春笋鲜重外 ,A、B、C处理均优于对照 ,C处理在各项生长指标中高于 A、B处理 ,B处理的多数指标优于 A处理。在所测的各项指标中 ,不同处理间均达到极显著水平。 C处理度产值为 2 5 5 0 0元 / hm2 ,产投比达 12 .1∶ 1,经济效益最好。
Use different transformation measures to the low-yield phyllostachys pubescens forest and analysis 9 growth indexes of phyllostachys pubescens transformed. The results show that measures A?B and C are better than CK expert rhizome diameter, the numbers of rhizome stage and spring bamboo shoots. The measure C is better than measures A and B in other indexes, and measure B is better than measure A. There is special marked difference in different measures in all indexes. Measure C may get 1700.29yuan/ha, and the proportion between output and investment is 12.1∶1.
