在毛主席革命路线指引下,为进一步落实毛主席“绿化祖国”、“实行大地园林化”的伟大指示,努力完成“全国农林科技座谈会”提出的“选择和培养速生用材树种的优良品种”的研究任务,我场积极开展了改建油松母树林的科研工作。在1973年至1974年的两年里,先后改建油松母树林138亩。改建后的母树林,树势生长旺盛,新梢发枝率显著增加,雌花及座果率比改造前增长两倍多,获得了初步成效。在改建油松母树林工作中我们有以下几点体会:
Under the guidance of Chairman Mao’s revolutionary line, in order to further implement Chairman Mao’s great instructions of “greening the motherland,” and implementing “the practice of the earth garden,” efforts have been made to complete the task of “selecting and cultivating fine varieties of fast-growing timber species” proposed by the “National Forum on Agriculture, Forestry and Science Technology” Research task, my field actively carry out the reconstruction of oil pine mother forest research work. During the two years from 1973 to 1974, 138 mu of oil pine mother wood was successively rebuilt. After the rebuilding, the trees and trees vigorously grow vigorously, the shoot emergence rate of shoots increased significantly, the female flower and fruit set rate increased more than twice before the transformation, and the preliminary results were obtained. We have the following experience in the work of rebuilding oil pine woods:
