Soil Erosion and Prevention Measures for Orchards in the Hilly Area

摘要

Since the reformation and opening to the outside world, great achievements have been made in the soil and water conservation controlling taking small watershed as the basic unit in Henan Province. The development of economic forest in the small watershed increases the economic benefit of comprehensive control and has made great contribution to shaking off poverty and getting rich for the masses in hilly areas. However, the existing problems in the management and unreasonable irrigation may easily result in soil and water erosion, make harm to the ecological environment of the forest, decrease the economic benefit and affect the sustainable development of economic forest. Therefore, to study the situation and prevention measures of soil erosion in hilly orchards, keep and increase ecological and economic benefit are key problems to be urgently resolved in the fields of soil and water conservation as well as ecological construction in the province. To investigate and analyze soil erosion of the orchards, a representative small watershed controlling district Huoshaoyang Gully, is chosen for observation and investigation. Experiments are carried out through contrastive irrigation of flooding and permeating. This article analyses the causes of soil erosion of the orchards and puts forward the following: (1) Strengthening the protection of field bunds. Soil erosion can be prevented effectively by geological protection and scientific management in line with local conditions. (2) Permeating irrigation is a good way to protect the hilly orchards from soil erosion.
