我场林木良种选育工作,是在顶着林彪、“四人帮”反革命修正主义路线的干扰和破坏开展起来的,自治区林业局十分重视和大力支持了我场的林木良种选育工作,把我场作为自治区唯一的西伯利亚落叶松良种选育基地.组织有关生产、科研和教学单位,有力的协助了我场这项工作的胜利开展.目前,已建成西伯利亚落叶松种子园512亩(其中嫁接定植384亩),母树林250亩,普遍进行了2一3次疏伐,选择优树40株,西伯利亚落叶松与日本落叶松杂交成功,得到球果39个,取得了林木良种选育工作的初步成绩. Forestry and wood seed breeding in our field is carried out under the interference and destruction against the line of counterrevolutionary revisionism by Lin Biao and the “gang of four.” The autonomous region’s forestry administration attaches great importance to and vigorously supports the breeding of seed trees in our field. As the only Siberian larch seed breeding base in the autonomous region, organizing relevant production, scientific research and teaching units has effectively assisted the victory of this work in our field. At present, 512 mu larch seed orchards have been built (of which 384 Mu), 250 mu of parent woods, generally 2 or 3 times of thinning, 40 trees of excellent trees were selected, the crosses of Siberian larch and Japanese larch were successful, and 39 cones were obtained. Preliminary achievements of tree seed breeding were obtained .
