摘要
基于对西藏拉萨地区油菜水分与产量的关系和需水规律进行研究,2013年在西藏拉萨节水灌溉试验站进行了油菜节水灌溉制度试验,通过设计田间不同灌水处理试验,结果表明,西藏拉萨地区的油菜的最佳灌溉定额在230—250m^3/亩之间,油菜灌水量250m^3/亩产量最高为181.63kg,油菜全生育期需水量一般在430~500 m^3/亩。
Based on the study of water and rapeseed production in Lhasa, Tibet＇s relations and regional water requirement law, we conducted Canola Irrigation Test at the water-saving irrigation experiment station of Lhasa, Tibet, 2013. Research through the design of field trials of different irrigation treatments, the results show that Lhasa, Tibet canola irrigation quota areas between 230-250m^3/acre, Rape irrigation 250m^3/acre yield of up to 181.63kg, rape water demand growth period is generally 430 - 500 m^3/acre.
