樟子松是欧洲赤松的变种,常绿针叶大乔木。原始林分布在北纬47度的大兴安岭南坡。它具有喜光耐寒、耐土壤干旱瘠薄、怕低洼积水等特性,是北方中山区阳坡和沙荒造林的先锋树种。我场于1963年开始引种,1966年开始大面积造林,目前全场已造樟子松幼林15000多亩。据调查,现在幼林长势良好,有的已郁闭成林开始结实。因此它将成为我场今后阳坡和沙荒造林的主要树种之一。几年来,我场樟子松引种造林所用的苗木都是我场大唤起分场的大梨树沟苗圃等单位培育的,他们在育苗的实践中,已摸索出培育樟子松合格苗的一整套方法。为适应今 Pinus sylvestris var. Mongolica is a species of evergreen coniferous trees. The original forest is located at 47 degrees north latitude on the southern slope of Daxinganling. It has the hi light hardy, resistant to soil arid infertility, fear of low water features such as stagnant water, is the northern sun and sand desertification afforestation pioneer tree species. My field began in 1963 introduction, large-scale afforestation began in 1966, the audience has made more than 15,000 mu of Scotch pine. According to the survey, young forest is in good shape now, and some of them have already started to grow. So it will become one of the main tree species in the future sunny slopes and desertification reforestation. In recent years, my field of Pinus sylvestris seedlings used in the afforestation are my big arouse sub-field big pear tree nurseries nurturing and other units, their practice in nursery, have been developed to cultivate qualified seedlings of Pinus sylvestris The whole method. To adapt to this
