摘要
为实现青海省柴达木盆地盐碱地的土壤改良与高效利用,解决畜牧业发展中优质饲草短缺难题,根据当前工作进展,结合实地调研、文献检索等方法,对柴达木盆地的盐碱地种草改良土地情况进行了梳理。初步掌握了柴达木盆地盐碱地的分布概况,总结了盐碱地种草改土的经验做法,分析了盐碱地种草改土过程中存在的不足与问题,提出了几点解决对策与措施。青海省柴达木盆地的盐碱地面积广阔且相对集中,今后需加强耐盐碱饲草品种的选育,摸清盐碱地特征及动态变化情况,多学科系统性研究种草改土技术,建立科学的综合评价体系,进而实现该地区不同盐碱地实用技术的集成与转化应用。
To realize the soil improvement and efficient utilization of the saline-alkali land in the Qaidam Basin of Qinghai Province and solve the problem of the shortage of high-quality forage grass in the development of animal husbandry.Based on the current progress of work,combined with methods such as on-site investigations and literature retrieval,the situation of grass planting for land improvement in the saline-alkali land of the Qaidam Basin was sorted out.The distribution overview of the saline-alkali land in the Qaidam Basin was preliminarily grasped.The experiences and practices of grass planting for soil improvement in the saline-alkali land were summarized.The deficiencies and problems existing in the process of grass planting for soil improvement in the saline-alkali land were analyzed,and several countermeasures and measures were put forward.The saline-alkali land in the Qaidam Basin of Qinghai Province is vast and relatively concentrated.In the future,it is necessary to strengthen the breeding of saline-alkali-tolerant forage grass varieties,find out the characteristics and dynamic changes of the saline-alkali land,carry out multidisciplinary and systematic research on grass planting for soil improvement technology,and establish a scientific comprehensive evaluation system,so as to realize the integration and transformation application of practical technologies for different saline-alkali lands in this area.
