补充资料：复种
| 复种 multiple cropping 一年内于同一田地上连续种植两季以上作物的种植方式。耕地复种程度用复种（种植）指数表示。  至1990年中国复种指数已达150.5％，长江以南各省平均在200％以上。中国复种的主要类型有：作物生长一熟有余，两熟不足地区为两茬套作；华北地区旱地多为小麦-玉米两熟或春玉米-小麦-粟两年三熟；江淮地区为麦-稻或麦、棉套作两熟；长江以南和台湾，为麦（或油菜）-稻和早稻-晚稻两熟、麦（或油菜、绿肥）-稻-稻三熟；旱地为大（小）麦（或蚕豆、豌豆）-玉米（大豆、甘薯）两熟，部分麦、玉米、甘薯套作三熟。热量条件是复种的主要限制因子。无霜期＞180天、≥10℃积温在3600℃以上地区，可以小麦与玉米套作一年两熟；无霜期＞230天、≥10℃积温在5000℃以上地区，可以种双季和实行稻田三熟。复种能提高土地和光能利用率，提高作物产量。 |
