在造林时,气候型的表现和利用,是决定提高森林生产力的重要手段之一,它的特点是生长很好。1974年和1975年春,我们研究了扎戈尔斯克试验示范林场和普拉弗丁斯克林场中等技校苗圃,通过播种营造的、不同地理种源的一年生和二年生云杉实生苗的生长。播种量按照每个地理种源,并根据每1000粒种子的发芽率、纯度和质量单独进行测定。播种前,对种子预先使用TMT制剂消毒。播种后用土、泥炭和锯木屑覆盖。出苗时苗床要遮荫。对播种地进行观察,在开始和大量出 When afforestation, the performance and utilization of climate is one of the important means to decide to improve forest productivity, which is characterized by good growth. In the spring of 1974 and the spring of 1975, we studied the growth of annual and biennial spruce seedlings of Zagorsk Experimental Demonstration and Provence Dinkinskömmer Secondary Technical Nurseries, which were planted and planted with different geographical provenances. Seeding rates are based on each geographic provenance and are determined separately based on germination rate, purity and quality per 1000 seeds. Prior to sowing, seeds are pre-sterilized with TMT formulation. Sown with earth, peat and sawdust. When seedling seedbed to shade. Sowing ground to observe, at the beginning and a lot of out
