crop rotation 輪作

China will expand its trials of crop rotation1 and fallow systems this year as part of efforts to facilitate the green development of agriculture. 今年我國將擴(kuò)大耕地輪作休耕制度試點規(guī)模，促進(jìn)農(nóng)業(yè)綠色發(fā)展。   “輪作”（crop rotation）指在同一田塊上有順序地在季節(jié)間和年度間輪換種植不同作物的種植方式。比如，在同一田塊上，一年種大豆，一年種小麥，一年種玉米，接下來每年按照上述順序輪換種植。在南方一年多熟的條件下，一年內(nèi)還可以按照季節(jié)進(jìn)行輪換種植。   “休耕”（fallow）指對肥力不足、地力較差的耕地，一定時期內(nèi)不種農(nóng)作物，但仍進(jìn)行管理和維護(hù)，以恢復(fù)地力。
