一、前言 一个树种在自然分布区内,由于当地气候土壤及经营条件的影响,形成了各种不同的生态型,并具有不同的遗传性,因此把种子播在不同于原产地的条件下就会在苗木性状及林分生态上产生差异。由于造林事业大规模进行,生产上从不同地区调引种子进行播种和造林又是不可避免的,因此进行各树种的地理播种和造林试验以确定各树种的种子可能调拨的范围及供选择优良类型,研究生态型等均具有重要意义,本试验卽基于这些目的进行。 国外如苏联有关这方面问题早有研究且订出本国内各树种种子的调运界限,给生产上带来便利。我国有关研究很少!解放后,林科院林科所在1956年进行了全国林木种子调拨区划和杉木态型及地理播种的研究。我们从1956年秋天从各省收集杉木和马尾松种子,1957年在福州地区育苗,并于1958年将育好的—年生苗木在三明莘口林场进行造林,马尾松一年生幼苗生长情况有关试验的部分结果曾发表在林业科学1959年第6期,本文主要是在莘口林场造林二年的初步小结。
I. INTRODUCTION A tree species in the natural distribution area, due to the local climate and soil and operating conditions, the formation of a variety of ecotypes, and has a different heredity, so sow the seeds in a different from the conditions of origin Differences in seedling traits and stand ecology. Since large-scale afforestation undertakings and the introduction of seeds from different areas for seed seeding and afforestation are inevitable, we conducted geographical seeding and afforestation trials of the species to determine the range of seeds that could be allocated to each species and for the selection of good types , Research ecology, etc. are of great significance, this test 卽 based on these goals. Foreign countries such as the Soviet Union have studied this issue for a long time and set the limits for the transportation of seeds of all kinds within their own country, bringing convenience to the production. After the liberation, after the liberation, the Linke Institute of Forestry Branch in 1956 carried out the national seedling allocation zoning and fir state and geographical seeding research. We collected Chinese fir and masson pine seeds from the provinces in the autumn of 1956, raised nurseries in Fuzhou in 1957, and nurtured them in 1958. The annual seedlings were planted in Sanming XinKou forest farm, and the part about the growth of annual Pinus massoniana seedlings The results have been published in forestry science in 1959, No. 6, this paper is mainly Xinlin forest farm afforestation for two years a preliminary summary.
