我县从1982年起在县林科所水杉林下进行了扦插水杉、留床繁育试验。通过六年实践,取得初步成效。试验调查数据分析整理如下: 一、试验地和试验方法试验地选择在县林科所1982年春季营造的水杉林地中,树种水杉株行距3×4m,定植苗龄三年。林地为中壤土,地下水位1m,PH值7.2。苗床设在林行间内,床宽3.0m,床高0.2m。林木株间扦插1行水杉,编序号为1行,床面上扦插6行水杉,行距0.5m,从东往西编号2—7行。每亩扦苗8万株,第二年留床8000株, My county since 1982 in the county Linke Suishu fir cuttings metasequoia, bed retention test. Through six years of practice, achieved initial results. Analysis of experimental investigation data are as follows: First, the experimental site and test methods to choose the experimental Lin County Forestry Bureau in 1982 spring to create the Metasequoia woodland, tree species of Metasequoia spacing 3 × 4m, planting seedling age of three years. Woodland is loamy, groundwater level 1m, PH value of 7.2. Seedbed located in the forest between the bed width 3.0m, bed height 0.2m. Tree cuttings 1 Metasequoia, serial number is 1, cuttings on the bed 6 Metasequoia, spacing 0.5m, from east to west No. 2-7 line. 80,000 plants per mu of seedlings, the second year to stay bed 8000,
