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(guó)將擴(kuò)大耕地輪作休耕制度試點(diǎn)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(lái)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(duì)肥力不足、地力較差的耕地,一定時(shí)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。
