The volume of actual protective forest stands in the Central Chernozem Region is presented, and the need for their additional creation is shown. It is noted that in recent years, side by side with the main forest tree species competitive cultivars of euramerican poplars varieties and some new hybrids obtained by domestic breeding have been introduced in the forest shelter belts and protective stands, which in the reclamation fund of the Voronezh region reached a height of 15 m at 20 years, 25 m at 30 years and 30 m at 42 years. After many years of testing in various soil and climatic environments of the region the selection of promising poplars varieties, hybrids and clones for protective afforestation was carried out. The following euramerican cultivars have been recommended: ‘Vernirubens’, ‘Robusta’, ‘Regenerata’, ‘Sacrau-59’ etc. From domestic hybrids ‘Pioneer’ and ‘E.s.-38’ (Elite seedling No. 38) can be recommended, which grow well in the floodplain conditions in dry steppe zone in Volgograd region. At 30 years, they reached a height of 24-25 m; and diameter – 28-31 cm. For comparison, similar growth indices (height about 20 m, diameter – 28-30 cm) oak shelter forest plantations in Kamennaya Steppe reached only by the age of 75 years.

介绍了中黑钙地区实际保护林的数量，并显示了对其进行额外创建的需要。值得注意的是，近年来，在森林防护林带和防护林中，引进了与主要林木树种并列的优势栽培品种欧美杨品种和一些通过国内选育获得的新杂交种。沃罗涅日地区在 20 岁时达到 15 m，在 30 岁时达到 25 m，在 42 岁时达到 30 m。经过多年对该地区各种土壤和气候环境的测试，选择了有前途的杨树品种、杂交种和无性系用于保护性造林。推荐了以下欧美品种：“Vernirubens”、“Robusta”、“Regenerata”、“Scrau-59”等。可以推荐国产杂交种'Pioneer'和'Es-38'（精英38号苗），它们在伏尔加格勒地区干草原带的洪泛区条件下生长良好。在 30 岁时，它们达到了 24-25 m 的高度；和直径 – 28-31 厘米。作为比较，相似的生长指数（高度约 20 m，直径 - 28-30 cm）在 Kamennaya 草原的橡树防护林人工林仅在 75 岁时达到。
