不同营林技术措施对马尾松人工林生长的影响

The influence of different silviculture technique for the plant of pinus massoniana growth

为探寻出最适合马尾松人工林生长量增长的营林技术措施,给马尾松人工林的经营和管理提供科学依据,在福建省连城县的马尾松人工林中设置试验样地,分别采用不同林地清理方式、不同整地方式、不同抚育方式等营林技术措施对样地进行处理或管理,2a、6a和10a后分别对马尾松植株胸径和树高的生长量进行测定并比较分析。结果表明,采取常规方式进行林地清理,全垦整地,再结合扩穴连带的抚育方式可使马尾松前期生长较快,但对马尾松的后期不利。对于种植周期超过10a的马尾松林,不同林地清理措施中,商业收获处理方式最有利于马尾松的树高、胸径保持良好的生长状况,常规处理方式的效果次之,全面清除植被方式的效果最差;不同整地措施中,穴垦处理措施的植株生长状况最好;不同抚育措施中,扩穴连带的处理措施植株生长状况最好,其次是块状抚育,不抚育的林地马尾松生长状况最差。

To explore the most suitable for the growth of Pinus massoniana Plantation silviculture measures the amount of growth, and provide scientific basis for the operation and management of Pinus massoniana Plantation of Pinus massoniana plantation, in Lianeheng County of Fujian Province Based on different land clearing growth mode, different land preparation methods and silviculture measures such as tending to the conduct or management of the plot, 2a, 6a and 10a, respectively on plant diameter at breast height and tree height growth of Pinus massoniana for measurement and comparison analysis. Results showed that conventional land--clearing, Ken land, coupled with expanding plug joint care enables the rapid early growth of Pinus massoniana, hut bad for the Masson later. For planting cycle over 10A of Masson pine, different woodland cleanup measures in the, commercial harvest processing way most con ducive to Masson of tree high, and diameter at breast height keep good of growth situation, General processing way of effect followed, full clear vegetation way of effect worst~ different whole to measnres in the, points Ken processing measures of plant growth situation best; different tending measures in the, spread points joint of processing measures plant growth situation best, second is block tending, not tending of woodland Masson growth situation worst.
