Experimental forest cultivations of Crimean pine were produced on cohesive-sandy soils with hilly terrain to show the possibility of using non-standard seedlings. The minimum height of the seedlings was 10 cm (a standard indicator) compared to 2.0…2.9 cm – the stem diameter at the root collar (a non-standard indicator). In an experiment the agronomic technique of preplant treatment of the seedlings’ root systems with a solution of Kornevin (a biostimulant, Agrosintez, Russia) was used. When creating forest cultures by hand planting, the differences between the experimental options in terms of the survival rate and the nature of variation depending on the quality of the seedlings used were not significant (actual Student’s and Fisher’s coefficients is less than tabular). Treatment of root systems with Kornevin solution contributed to a more even distribution of the plants in the area. Mechanized planting did not provide for a high survival rate of forest cultures (the rate was 58.4% in the 1st year and 37.3% in the 3rd year), while the surviving plants did not form a homogeneous population (variation factor 30.5…71.0). The results indicated that it was possible to use seedlings of non-standard sizes in renewal after treating root systems with solutions of root stimulants.

克里米亚松的试验性森林种植是在丘陵地形的粘性沙土上进行的，以显示使用非标准幼苗的可能性。幼苗的最小高度为 10 厘米（标准指标），而根领处的茎直径为 2.0…2.9 厘米（非标准指标）。在一项实验中，使用了 Kornevin（一种生物刺激剂，俄罗斯 Agrosintez）溶液对幼苗根系进行种植前处理的农艺技术。当通过手工种植创建森林培养物时，根据所用幼苗的质量，实验选项在存活率和变异性质方面的差异并不显着（实际的学生和费舍尔系数小于表格）。用 Kornevin 溶液处理根系有助于使该地区的植物分布更均匀。机械化种植不能提供高的森林培养成活率（第一年为 58.4%，第三年为 37.3%），而成活的植物没有形成同质种群（变异因子 30.5…71.0）。结果表明，在用根刺激剂溶液处理根系后，可以使用非标准尺寸的幼苗进行更新。
