我场职工于1973年以来,大破科学神秘论,自力更生开展国外松扦插育苗试验,收到了良好效果。现在已扦插10.6万多株,一般成活率为40-50%,最高达90%以上。苗木生长健壮,长势喜人,平均高8-24厘米,最高36厘米。现将我们的具体做法简介如下: 认真选圃细致整地选择土壤深厚、肥沃、疏松、水源充足、排灌方便、病虫害少、pH值5.5-6的沙质壤土作圃地,避免用死黄土、粘重土、地下水位高、含石砾较多或低洼积水地作圃地。圃地要深翻细整,施足基肥。苗床高20-25厘米,宽100厘米,留步道40-50厘米,以便管理。
Our staff and workers in 1973, breaking the scientific mystery, self-reliance pine cuttings to carry out foreign trials, received good results. Now more than 106,000 cutting lines, the general survival rate of 40-50%, up to 90% or more. Seedlings grow robust, growing gratification, the average high 8-24 cm, up to 36 cm. We will now introduce the specific practices are as follows: Carefully selected carefully select the site of soil preparation deep, fertile, loose, adequate water, irrigation and drainage convenience, less pests and diseases, pH 5.5-6 sandy loam as a land, avoid dead loess, sticky Heavy soil, groundwater level is high, with more gravel or low-lying water for land. Nursery to deep plowing fine, Shizujifei. Seedbed height 20-25 cm, width 100 cm, stay trail 40-50 cm, in order to manage.
