二十多年来我们对桉树造林密度问题进行了各种探讨和试验研究,生产实践中采用的造林密度大致经历了由密到疏,再由疏发展到适当密植的过程。植点配置方式也从单一的正方形配置发展为长方形,品字形或“双龙出海”等宽行密株的方式,密度的植点配置方式的变化,反映出人们对客观规律的认识加深和营林措施的改进、提高。五十年代林场建立初期,雷州半岛干旱风沙为害严重,为了短服内绿化雷州,
In the past two decades, we have conducted various studies and experiments on the density of eucalypt plantation. The planting density adopted in production practice has generally gone through the process of dense to sparse and then dense to dense. The pattern of site allocation also changed from a single square configuration to that of a rectangular, glyph or “Ssangyong to the sea” with a wide and dense line. The changes in the density of the site allocation patterns reflected the deepening of people’s understanding of the objective laws Improvement measures to improve. In the early 1950’s when the forest farm was established, the dry sand and winds of the Leizhou peninsula were severely damaged. In order to green Leizhou in short service,
