Abstract:

To investigate the effect and mechanism of different rotation systems on nitrate leaching,field experiments were carried out from 2018 to 2020 to compare the variation characteristics of nitrate leaching in greenhouse soil under three rotation systems,i.e.tomato-melon(TM),bean-melon(BM)and tomato-bean(TB),and to explore the controlling factors for differences in nitrate leaching.Results showed that the rotation with Vigna unguiculata significantly reduced the amount of nitrate leaching compared with the traditional TM rotation.The total nitrate leaching loss of TB was significantly decreased by 39.74% compared with TM,however,the nitrate leaching loss of BM were significantly decreased by 6.32%.Collectively,TB had the best environmental benefits among three rotations,which was the recommended rotation pattern.Spearman correlation analysis showed that the NO3-NO3--N leaching was most affected by 0—100 cm soil water storage,soil NO3--N accumulation and temperature,with a highly significant positive correlation.A positive correlation of NO3--N leaching with 0—100 cm organic carbon storage and soil total nitrogen accumulation,as well as a negative correlation with 0—60 cm soil pH value were also observed.Comparing with the traditional TM,the decreasing of nitrate leaching in recommended rotation pattern(TB)was mainly attributed to significant reduction of 0—100 cm soil water storage,soil NO3-N and total nitrogen accumulation,and significant increment of soil pH value to chang soil physical and chemical properties,together with alleviating the background nitrate leaching caused by organic nitrogen mineralization in sensitive leaching seasons.
