轮作休耕是耕作制度的一种类型或模式,是有效利用耕地资源、提升耕地综合产能的有力措施。当前,急需在全国一些重点地区推行轮作休耕制度试点,从而实现污染耕地的绿色修复。在粮食连年增产的同时,耕地资源环境面临多重挑战。耕地被高强度利用、长期高负荷运转,得不到休养生息,因此耕地地力严重透支,耕地质量退化、耕地污染尤为突出,严重制约了我国农业的可持续发展。科学推进污染耕地轮作休耕制度,加强污染耕地生态修复,
Rotation fallow is a type or model of farming system, and it is a powerful measure to make effective use of arable land resources and increase the comprehensive productivity of arable land. At present, it is urgently necessary to launch a pilot scheme of rotation fallow system in some key areas in the country in order to achieve green restoration of contaminated farmland. While food production has been increasing year after year, the resources and environment of cultivated land are faced with multiple challenges. Due to the high utilization of cultivated land and long-term high-load operation, the cultivated land is not recuperated. As a result, land fertility in cultivated land is seriously overdrawn, the quality of cultivated land is deteriorated, farmland pollution is particularly prominent, and the sustainable development of agriculture in China is severely restricted. Scientifically promote the rotation of arable land for fallow system, strengthen the ecological restoration of arable land,
