“蚕豆—青稞”减肥增效栽培模式试验

Test on the Cultivation Model of Broad Bean and Highland Barley Reduce Fertilizer and Increasing Efficiency

共和县塘河地区主要种植青稞、油菜等农作物,种植作物单一、多年连作,导致施肥增多,病虫害严重。针对连作和"油菜—青稞"常年轮作带来的一系列问题,开展了"蚕豆—青稞"轮作的减肥增效栽培模式。试验结果表明,"蚕豆—青稞"栽培模式比"油菜—青稞"栽培模式增收明显,农药残留对二次栽培的作物药害低。"蚕豆—青稞"栽培模式具有节本、增效、增收的优点,在塘河地区乃至青稞种植区域推广应用该技术是今后藏区粮食栽培的一条新路子。

The Tanghe area of Gonghe County mainly grows barley,rape and other crops,and grows a sin- gle crop.Years of continuous cropping,resulting in increased fertilization,serious pests and diseases.Aiming at a series of problems caused by continuous cropping and "rapeseed highland barley"rotation,the cultivation mode of "broad bean -highland barley"rotation was carried out.The results showed that the cultivation pattern of "broad bean and highland barley"increased significantly than that of "rapeseed and highland barley", and the pesticide residue was less harmful to the crops under secondary cultivation.The cultivation mode of "broad bean and highland barley"has the advantages of saving cost,increasing efficiency and increasing income.Popularizing and applying this technique in Tanghe area and even in highland barley planting area is a new way for grain cultivation in Tibetan area in the future.The promotion and application of this technology in the Tanghe area and even the highland barley cultivation area is a new way for future grain cultivation in Tibetan areas.
