增加玉米茬口对连作青菜土壤理化性质的影响
Effects of increasing maize stubble on annual production of Pak choi(Brassica campestris ssp.chinensis Makino)
摘要
Abstract
In order to investigate the impact of maize cultivation on the soil improvement for continuous Pak choi,the influence of increasing maize stubble on the physicochemical properties and enzyme activity of soil for continuous Pak choi was examined using'Yanqing'and'Shenke Tiannuo 99'as experimental materials.The results showed that the maize-greens rotation pattern had a significant effect on the accumulation of soil organic matter,total nitrogen and quick-acting nitrogen,total phosphorus and available phosphorus content.Furthermore,this pattern could reduce the soil bulk density and maintain the stability of soil porosity and water content.The activities of soil enzyme were found to be significantly enhanced following the harvesting of the maize.In conclusion,the maize-Pak choi rotation pattern had been demonstrated to exert a discernible influence on soil improvement.关键词
