1987～1991年,协作组选用马尾松、未荷、枫香、漆树、野漆树、山乌桕、黄檀、毛白檀、黑荆树、胡枝子、黄荆等树种,进行了混交树种的选择、混交方式、种子处理技术、植被处理与成效,主要飞播树种的成苗规律和飞播作业技术等专题研究。经过5年试验研究,基本上掌握了飞播建立针阔叶混交林的技术关键,为今后开展大面积飞播混交林提供了科学依据。
From 1987 to 1991, the cooperative group selected the species of mixed tree species, such as masson pine, unmerged, sweetgum, lacquer tree, wild lacquer tree, mountain black sandalwood, yellow sandalwood, white sandalwood, black wattle, Lespedeza, Huang Jing, Hybrid methods, seed treatment techniques, vegetation treatment and effectiveness, the main planted seedlings of the law of seedlings and aerial seeding operations and other topics. After five years of experimental research, we have basically mastered the key technology of establishing a coniferous and broad-leaved mixed forest by air-sowing and provided a scientific basis for carrying out large-area aerial seeding mixed forest in the future.
