大棚蔬菜栽培是陕西宜川县的一项新兴主导产业,为了保证这一产业持续、稳定、快速发展,县农业中心在大棚蔬菜上大力推广了测土配方施肥技术,为菜农提供“测、配、施”一体化服务。实践证明:测土配方施肥技术具有节省肥料,提高肥料利用率,降低农业成本等作用,达到增产、增收之目的。县土肥站2002～2006年对全县1820个蔬菜大棚土样测定及试验结果表明,采用配方施肥技术,平均增产幅度一般8%～15%,最高达20%以上,每公顷降低化肥成本150～225元,化肥利用率可提高5～10个百分点。
Greenhouse vegetable cultivation is a new leading industry in Yichuan County, Shaanxi Province. In order to ensure the sustained, steady and rapid development of this industry, the county agricultural center vigorously promoted the technology of soil testing and formulating and fertilization on greenhouses and vegetables, provided “ With, Shi ”integrated services. Practice has proved that: soil testing and fertilizer technology has the effect of saving fertilizer, improving fertilizer utilization, reducing agricultural costs and so on, to achieve the purpose of increasing production and increasing income.
