The systems of protective plantations transform agro-territories of the forest-steppe of the European part of Russia. With an area of artificial linear plantings in the Central Black soil region of 600000 ha, negative natural phenomena and erosion processes in landscapes were significantly reduced. In windbreaks with fast-growing tree species, the highest growth rates are observed with a row spacing of 3.0 m and a tree spacing of 1.0 m. A convex transverse profile is formed in middle-aged stands, where the height of the middle rows is higher by 12.1 - 17.2% than in the extreme. The average tree growth continues up to 30 years. The growth rate is 0.73 - 0.83 m/year with the decrease from the age of 15-24 years. In the system of forest belts during the growing season, there is an increase in relative humidity of 1.8 - 9.8%, which altogether leads to an increase in the yield of grain crops by 330 - 550 kg/ha. The formation of plantings on the arable land of optimal parameters and structures will make it possible to have biological structures of long-term use with an increasing reclamation effect.

保护性人工林在森林草原带条件下的生长及改良作用

保护性种植园系统改变了俄罗斯欧洲部分森林草原的农业领土。中央黑土区人工线状种植面积达 60 万公顷,景观中的负面自然现象和侵蚀过程显着减少。在速生树种的防风林中,行距为 3.0 m 和树距为 1.0 m 时的生长速率最高。中龄看台形成凸出的横向剖面,中间行高比极端高出12.1-17.2%。树木的平均生长持续长达 30 年。从15-24岁开始,增长率为0.73-0.83m/年。在生长季节的森林带系统中,相对湿度增加了 1.8 - 9.8%,这总共使粮食作物的产量增加了 330 - 550 公斤/公顷。在具有最佳参数和结构的耕地上种植植物,将有可能具有长期使用的生物结构,并具有越来越大的开垦效果。
