林地培肥是加速苗木生长,促进林木速生丰产的重要手段。为探索这方面的经验,我们曾对樟子松幼林作了施用不同肥料及其配比的试验。现将试验结果报告如下: 一、试验地自然概况试验地设在临江林业局银山林场西岗老银山,土壤为玄武岩台地白浆土,坡向南,缓坡,海拔高800米。二、试验过程樟子松为一九八三年栽植的二年生苗。全试验共设8个处理,16个小区,每小区10株,横坡2行,每行5株,两个重复。顺坡由上至下的小区排列如下: Ⅱ_1 Ⅴ_1 Ⅰ_2 Ⅶ_2 Ⅳ_2 Ⅶ_1 对照_1 Ⅰ_1 Ⅳ_1 对照_2 Ⅴ_2 Ⅳ_2 Ⅱ_2 Ⅵ_1 Ⅲ_1 施肥处理见表1
Woodland fertilization is to accelerate the growth of seedlings, an important means of promoting fast-growing forest yield. In order to explore this experience, we have applied different fertilizers and their proportions to Pinus sylvestris young forests. Now the test results are reported as follows: First, the natural conditions of the experiment The experiment is located in Laosinyin, Xigang, Yinshan Forest Farm, Linjiang Forestry Bureau. The soil is basal white soil of basaltic plateau. The slope is southward and gently sloping with elevation of 800 meters. Second, the test process Pinus sylvestris planted in 1983 two-year-old seedlings. There are 8 treatments in total, 16 cells, 10 cells in each cell, 2 lines in cross slope, 5 lines in each line, two replicates. The slope from top to bottom of the plot are arranged as follows: Ⅱ_1 Ⅴ_1 Ⅰ_2 Ⅶ_2 Ⅳ_2 Ⅶ_1 control _1 Ⅰ_1 Ⅳ_1 control _2 Ⅴ_2 Ⅳ_2 Ⅱ_2 Ⅵ_1 Ⅲ_1 fertilizer treatment in Table 1
