摘要: 设计5种三熟复种新模式,即"中早熟水稻-生菜-小麦"、"中早熟水稻-大豆-小麦"、"中早熟水稻-玉米//甘薯-小麦"、"中迟稻水稻-莴笋/油菜"和"中迟稻水稻-马铃薯/油菜",以"水稻-小麦"传统模式作对照,于1996~1998年在广汉市三水镇进行同田大区定位试验。结果表明:①新种植模式对土地、劳力及光热资源的利用率都比传统模式有了显著提高,纯收益以"中早熟水稻-生菜-小麦"模式最好,其次为"中早熟水稻-大豆-小麦"、"中迟熟水稻-马铃薯/油菜"和"中迟熟水稻-莴笋/油菜",而"中早熟水稻-玉米//甘薯-小麦"模式的经济效益最差。②通过品种选择与茬口调节,采取连作和套作两种方式,形成的具有较高经济效益和稳定性能的稻田三熟制,较好地满足了本区"稳粮调结构、增收奔小康"的客观需求。

Abstract: In 1996~1998, multiple cropping models are conducted in the west plain of Sichuan Province of China. The results show that the highest income was obtained from the model of "middle early rice cos. lettuce wheat". It return 20716.5 Yuan/hm2, that is 178.3% higher compared with in the model of "middle rice wheat" (CK). The incomes of "middle late rice potato/rape", "middle early rice soybean wheat" and "middle late rice lettuce/rape" are respectively 17667.0 Yuan, 17466.0 Yuan and 15411.0 Yuan/hm2 which are higher 137.3%, 134.6% and 107.0% than that in CK. The ecological and social benefits are improved significantly by the multiple cropping, including more efficient use in the local farm labor force and some natural resources, such as cropland, solar energy, etc.
