防止土壤侵蚀提高作物产量是现代集约经营的迫切任务。在先进的综合农业技术措施中,农田防护林带起到了重要作用。 在克里米亚,风蚀为害81万公顷的土地,占总面积30.6%。这里尘风暴平均每10年就有7次之多。而在萨克斯克和列宁斯克地区,尘风暴几乎每年都有。在草原区大约40%的经济区都设置了林带体系,这些造林面积占2%的林带保护30多万公顷农田。 为测定防护林对冬小麦、冬大麦产量的影响,我们从1976—1980年在萨克斯克、辛母弗罗布尔、克拉斯诺格瓦尔迭斯克、詹科依、下高尔斯克和苏维埃等地区的农业生产单位调查
Preventing soil erosion Increasing crop yields is an urgent task for modern intensive management. Among the advanced integrated agricultural technologies, farmland shelterbelts have played an important role. In the Crimea, wind damage caused 810,000 hectares of land, accounting for 30.6% of the total area. Here, dust storms have an average of seven times every 10 years. In the Saxics and Leninsk regions, dust storms occur almost every year. About 40% of the economic zone in the Prairie Region is equipped with forest belt systems, which account for more than 300,000 hectares of farmland with 2% of the forest belts. In order to determine the impact of shelterbelt on the yield of winter wheat and winter barley, from 1976-1980 agriculture in the regions of Saxik, Sinofloor, Krasnogalls Dziesk, Zankote, Lower Gersk and the Soviets Production unit survey
