- Abstract:
- Through research for the impact on soil quality by four land use types and the cultivation measure,the following conclusions could be drawn.① The soil salinization presented the gradient change,namely from the under part of diluvia fan,the alluvial plain to the desert,the soil types alternately presented medium sanitized soil,highly sanitized soil,sanitized soil and non-sanitized soil.② The average contents of soil organic matter,available potassium,available phosphorus and available nitrogen in natural oasis were higher than the contents of the other three kinds of land use patterns.The content of nutrient in the desert was very low,but the content of nutrient had positive correlation to salinization,so it was an important means to improve land productive potentialities to prevent and control the salinization by utilizing salt catch plant resources,increasing salt vegetation coverage.③ The contents of soil organic matter and available potassium in the artificial oasis were relatively low.The main reason was that more emphasis was taken on chemical fertilizer during the agriculture production,but ignored the combination of chemical fertilizer and organic manure which was helpful the accumulation of organic matter and potassium.④ Owing to the comparatively unanimous chemical fertilization on cotton which was the main crop in Jinghe basin,each nutrient element in the artificial oasis presented lower variance coefficient than other three kinds of land use patterns.⑤ The change of soil water soluble salt contents firstly decreased to the valley value then turned to increase stably with the accumulation of cultivation time,and the other soil elements showed the similar change trend,especially organic matter change was comparatively obvious among them.These changes had important relationship to continuous cotton cultivation,unreasonable irrigation and exhaustive utilization of farmland,etc.
