- Abstract
【Objective】 To study the effect of typical farmland shelterbelts on soil water and salt dynamics of cotton field.【Method】 The cotton field-shelterbelt system of the 150th Regimental Farm in Shihezi, Xinjiang, was used as the research object, the water and salt content and evaporation of the shelterbelt in 0.1H, 0.25H, 0.5H, 1H, 2H and 3H regions and the forest land were analyzed.【Results】 (1) The shallow roots of the shelterbelt competed with the cotton plants for water in the range of 0.25H; (2) The salt content of the soil under the shelterbelt of cotton field was lower than that of the cotton field without shelterbelt, the salt content of the shallow soil of 0-20 cm was generally lower, and there was no salinization in the cotton field within 0.5H from the shelterbelt, the cotton field of this regiment field was basically maintained in the range of non-salinization or slight salinization; (3) The desalination effect of farmland shelterbelt was obvious, and especially at 0.1H the average desalting rate was above 14.38%, that was, the closer to farmland shelterbelt, the more obvious the desalting effect was. 【Conclusion】 The serious competition for water in the shelterbelt edge can increase the irrigation frequency of the shelterbelt, and the shelterbelt has obvious desalination effect on the edge soil of forest belt, which can prevent the salinization of soil in this life.
