树木苗圃本是生产苗木的场地,随着营林科学的发展,苗圃的用途不断扩大,用苗床上的苗木模拟人工林,用苗木换床移植模拟造林过程,在解决造林与森林经营活动中的若干技术疑难,已显出引人注意的效果。用树木苗圃作森林经营活动的模拟试验场,可用较少的资金,在短期内解决造林、森林经营活动中某些关键性问题。一、对人工林密度管理的模拟人工林密度管理的实质,就是按林分适宜密度变化规律,及时地进行密度调整,其 Tree nursery is the site of the production of seedlings, with the development of science campuses, the use of nurseries continue to expand, with seedlings on the seedbed simulation of artificial forests, seedlings for bed transplanting simulation of afforestation process, in addressing afforestation and forest management activities A number of technical difficulties have shown remarkable results. With tree nurseries as a simulation test site for forest management activities, some key problems in afforestation and forest management activities can be solved in a short period of time with less capital. First, the artificial plantation density management simulation The essence of plantation density management, that is, according to the law of the density of forest suitable for changes in density in a timely manner to adjust the
