Study on the Status Quo and Damaged Patterns of Vegetable Soil Secondary Salinization in Qinghai Province
摘要
Abstract
[Objective J The aim was to provide theoretical basis for the sustainable application of facility soil in Qinghai Province and guidance for greenhouse cultivation. [ Method ] The salt, nitogen, available phosphorus and available potassium, organic content and pH and soil nutrition in the open space in different places and plantation years were compared. [ Result] The average soil salinity was reached 0. 31% and 4. 2 times than it in the open field. The occurred rate of secondary salinization was reached 65%. And with the extension of greenhouse cultivate period, soil salinity has a rising trend year by year. As the deepening of soil section, salinity and nutrient content was gradually decreased. The soil salt content is mainly concentrated in the soil surface. There has a certain tendency of surface accumulation. [Conclusion] Facility soil secondary salinization has became an important limitation factors for the production of facility vegetable in Qinghai Province.关键词
