由四川农业大学主持研究的“九五”重点科技攻关项目之一《川中丘陵区主要农作物持续增产综合技术研究与示范》取得令人瞩目的成绩,其中稻田新“三熟”制使稻田真正成为农民增粮增收的“聚宝盆”。 稻田新“三熟”制是以玉米和水稻为主体,搭配一熟或两熟其它粮经作物的一年三熟的高效种植制度。该制度的关键是初春采用地膜覆盖栽培,早播玉米早熟高产,为二季种稻提供足够的热量条件。它主要包括“蔬菜(饲料)——玉米——水稻(玉米、花生)”和“小麦——玉米——水稻(玉米、花生)”两种类型。试
One of the key scientific and technological projects under the “Ninth Five-year Plan” held by Sichuan Agricultural University is “Research and Demonstration of Integrated Technology for Continuous Increase of Main Crops in Central Sichuan Hilly Region”, and the new “three-ripe” system in paddy field has made rice fields truly become Increasing income of farmers by the “cornucopia.” The new “three ripening” system in paddy field is a high-efficiency planting system with three crops per year, which is mainly composed of corn and rice and one or two other grain-and-grain crops. The key to the system is early spring mulching cultivation, early sowing of corn, high yield early maturity for the second season rice to provide adequate heat conditions. It mainly includes two types of “vegetables (feed) - corn - rice (corn and peanut)” and “wheat - corn - rice (corn and peanut)”. test
