[目的]为生姜优质高产施肥提供科学依据。[方法]以四川竹根姜为研究对象,研究其土壤养分含量现状以及植株养分含量等特性。[结果]重庆(永川)种苗科技城生姜种植区土壤整体偏酸性,有机质含量偏低,全部土样碱解氮含量属于适量水平,土壤中有效P、Ca、Mg、Fe、Mn、Cu、Zn含量丰富,S含量缺乏。生姜植株各部位氮钾含量较高,磷含量较低,生姜块根和茎秆中K元素含量大于N元素含量,叶片中N元素含量大于K元素含量。[结论]在生产中应因地制宜,合理施肥,并控制氮、钾肥配比,可以促进生姜的生长,提高生姜产量。
[Objective] The aim of the study was to provide scientific basis for high quality and high yield fertilization of ginger. [Method] The root of D. zingiberensis was taken as research object to study the status quo of its soil nutrient content and its nutrient content and other characteristics. [Result] The overall soil acidity and organic matter content in the ginger planting area of Chongqing (Yongchuan) Seedling Science and Technology City were relatively low. The content of alkaline hydrolysis nitrogen in all soil samples belonged to the proper amount. The available P, Ca, Mg, Fe, Mn, Cu, Zn content is rich, lack of S content. The contents of nitrogen and potassium were higher in all parts of ginger plant, lower in phosphorus content. The content of K in root and stem of ginger was higher than that in N, and the content of N in leaves was higher than that in K. [Conclusion] In the process of production, ginger should be promoted according to local conditions, fertilize rationally and control the proportion of nitrogen and potash fertilizer to increase the yield of ginger.
