摘要
填闲作物在设施蔬菜生产轮作体系中的应用是近年防治土壤氮素损失和土壤硝酸盐淋溶的新兴措施.研究表明,这一措施的应用,能有效地控制氮素的淋溶,对设施蔬菜生产产生了显著的经济效益和生态效益,同时对设施蔬菜可持续生产具有重要的意义.根据国内外文献资料,概述了填闲作物在保护地蔬菜种植中的作用、土壤硝酸盐淋溶的阻控机制及影响填闲作物阻控硝酸盐淋溶的因素.
It is a new measure to prevent nitrogen loss through nitrate leaching by using nitrogen catch crops in the vegetable rotation system recent years. The results showed that this measure could effectively prevent nitrogen loss through nitrate leaching and bring notable economic and ecological benefits in the production of vegetable. It also had positive effects on sustainable vegetable production. To sum up the related information home and abroad, the function of nitrogen catch crops in the vegetable fields and the mechanism of nitrogen catch crops to control nitrate leaching from soil as well as the factors affecting nitrogen catch crop to control nitrate leaching from soil were summarized.
