چکیده انگلیسی مقاله |
The city of Isfahan is exposed to soil erosion and dust due to arid climate, low rainfall with poor distribution and desertification. Borkhar is one of the important Detachment areas of wind erosion in Isfahan province. Therefore, finding solutions that can reduce soil erosion is a clear priority. Construction of a windbreak is one method to reduce the speed of erosive winds. Due to water shortage and soil limitations in the study area, it is not economical to use a live windbreak that requires a lot of irrigation.Therefore, in this study, Kochia scoparia L (Schrad) is used, which is a suitable plant for the construction of windbreaks in saline lands. In this study, the plant seeds planted in the ground and the required water provided by irrigation. This phase lasted for two month. After full growth of seedlings, irrigation was stopped and dried seedlings become non-living windbreak. This type of windbreak lasts for 3 years, stabilizes the soil and controls soil erosion. The size, dimensions and number of windbreak rows were calculated based on the data obtained from the estimation of erosion threshold and the measurement of erosion and sedimentation of treatments in the study areas was investigated. So far, this type of plant has not been used anywhere in the world, and with this method and the way it is planted, a new method can be invented without the need for much water. It is also possible to preserve crops in the shade of this plant. |
