补充资料：旱地三熟制(triple cropping in rainfedarea)
| 旱地三熟制(triple cropping in rainfedarea) 在同一块旱地上，一年内接连或套种三季作物的种植方式，简称旱三熟。中国早在18世纪，就有三茬套种的记载。 旱三熟在中国主要分布在： ≥10℃的积温在5000-8000℃以上，无霜期250天以上至终年无霜，年降水量900mm以上的长江流域和西南部分地区，为了充分利用生长季节和土地，常用带状套作或留行套作的方式，将三种不同季节种收的旱地作物组成套作三熟。在热量条件充足，≥10℃积温在6500-8000℃以上的珠江流域，一年之内可以连续种收三季旱作物，成为复种三熟。旱地套作三熟，系由三种不同季节种收的作物组成的复合群体，其种植技术比旱地复种三熟和非带状套作三熟要求更高。以四川省比重最大的小麦／玉米／甘薯三茬套作为例，其技术要点为：按1.6-2m复合带距为一单元，对等分为甲、乙两个种植带，第一年，甲带种小麦 —甘薯，乙带种冬绿肥——春玉米＋大豆—秋绿肥(或秋豆、秋菜)，第二年甲、乙两带交替茬口，换带种植。如此往复循环，形成定期带状轮作。旱地三熟制高产的关键，是要解决好三季作物共生期间的矛盾。(1)选用矮秆、早熟、高产的品种，合理搭配。(2)采用管理方便，有利三季作物均衡增产的带距和带比，建立合理的复合群体结构与密度；(3)因地制宜，安排好多种作物，合理实行带状轮作；(4)适时套种，加强共生期的田间管理。 |
