| 英文简介 | With the large area popularization and application of drip irrigation technology, soil salinity in cotton field increased year by year, which will aggravate the risk of the soil salinization, led to environmental degradation and reduction of output in cotton field. In order to solve these problems, based on the research on saline-alkaline soil amelioration and government in early stage, typical study fields that have been reclaimed many years ago using drip irrigation technique were chosen as the object of study. Based on groundwater and soil water dynamics, insist on that safety in drip irrigation is the supreme to improve soil quality in cotton field, to carry out the study on the principle of soil water and salt migration, the technical of salinity-control during the non-growth period, the movement process of salt under the condition of freezing and thawing and the salt elimination model that suit for the drip irrigation field, to establish numerical model on the movement of soil water-salt-heat. According to water-soil-plant, by the study on the effects of different spring and winter irrigation regime on soil salt during non-growth period, the elimination model will be analyzed and researched, and the results of different elimination model will be assessed in order to found a economic and efficient elimination model, which will provide technical assistance for the sustainable utilization of soil、the establishment of environment friendly irrigation region and the large popularization of drip irrigation technical. |
