杉木是我场主要经营树种之一。解放后,在毛主席“绿化祖国”的伟大号召指引下,积极营造了杉木林13000多亩,占全场造林面积的30％。但过去由于受修正主义路线的干扰,我们对采用良种造林的重要性认识不足;营造杉木所用的种子是从外地采购的,品种不纯,质量较差,造成杉木林分差异很大,在13000亩的杉木林中,生长较好的林分只有2000亩,占成林杉木面积的58％,大部分杉木林生长不良,或成“小老树”林分,生长量很低。而且同一林分中,个体之间差异也很大。1958年营造的杉木林,生长良好的平均胸径达20厘米,而差的不足10厘米,最好的也不过31厘米。1972年我省林木良种会议之后,场党支部广泛发动群众,针对我场杉木林生长情况,深刻的学习了毛主席关于“有了优良品种,即不增加劳力、肥料,也可获得较多的收成”的教导,全场职工一致认为,要迅速营造速生、高产、优质的杉木林,就一定要选用良种。搞不搞杉木良种选育,是关系到能不能执行毛主席革命路线,多、快、好、省地发展林业生产的重要问题。于是我们组织了领导、工人、技术人员“三结合”的杉木良种选育科研小组,开展了群众性的杉木良种选育活动。几年来,已取得初步成绩,改建了100亩母树林,选出优树17株,建立优树来穗圃 5亩,种子园定砧60亩。
Chinese fir is one of the main tree species in our field. After the liberation, under the great call of Chairman Mao’s “greening the motherland,” we actively created 13,000 mu of fir forest, accounting for 30% of the total afforestation area. However, due to the interference of the revisionist line in the past, we did not know enough about the importance of afforestation. The seeds used for planting fir were purchased from other places. The impure species and poor quality resulted in great differences in fir stands. At 13000 Acres of fir forest, the growth of better stands only 2,000 acres, accounting for 58% of the area of Chinese fir, most of the Chinese fir forest poor growth, or into a “small old tree” stands, the growth is very low. And the same stand, the difference between individuals is also great. Cedar forest created in 1958, the average well-growing diameter of 20 cm, but less than 10 cm, the best but also 31 cm. In 1972, after the forest tree planting conference in our province, the party branch of the field widely mobilized the masses. In response to the growth of Cunninghamia lanceolata in our field, Prof. Chairman Mao profoundly learned that “with excellent varieties, that is, without increasing labor and fertilizer, Harvest ”, all the workers agreed that to quickly create a fast-growing, high-yielding and high-quality Chinese fir forest, it is necessary to select good varieties. To engage in breed selection and breeding of fir is an important issue that concerns whether it is possible to implement Chairman Mao’s revolutionary line and to develop forestry production in a large number of ways, quickly, well and economically. So we organized leaders, workers and technicians to “triple” fir seed breeding research group to carry out the mass breeding of Chinese fir seed. Over the past few years, preliminary achievements have been made, and 100 mu of parent tree forest have been reconstructed. 17 trees of excellent trees have been selected, and 5 mu of spruce trees have been established and 60 mu of seed orchard fixed anvils have been established.
