华北平原夏玉米缓控释肥种肥同播技术规程

Technical Regulations for Simultaneous Sowing of Seed and Slow and Controlled Release Fertilizer for Summer Maize in North China Plain

以华北平原夏玉米为例,对夏玉米缓控释肥种肥同播技术中的种子、肥料、施肥机械选择以及施肥量和施肥位置的确定进行了规范。大田试验结果表明:与习惯施肥和施用普通复合肥处理相比,采用缓控释肥种肥同播处理的夏玉米分别增产8.99%~46.19%和4.09%~13.52%,增收率为26.27%~99.18%和16.22%~33.37%。种肥同播技术可减轻劳动强度、减少环境污染、降低生产成本、增加农民收入,是良肥、良种、良法的有机结合。

Taking summer maize in the North China Plain as an example,the selection of seeds,fertilizers,fertilization machinery,and the determination of fertilization amount and fertilization position in the technology of simultaneous sowing of seed and slow and controlled release fertilizer for summer maize are standardized.The results of field experiment show that compared with conventional fertilization treatment and common compound fertilizer treatment,the yield of summer maize treated with simultaneous sowing of seed and slow and controlled release fertilizer increases by 8.99%-46.19%and 4.09%-13.52%respectively,and the income increase rates are 26.27%-99.18%and 16.22%-33.37%.The technology of simultaneous sowing of seed and fertilizer can reduce labor intensity,reduce environmental pollution,reduce production costs and increase farmers′income.It is an organic combination of good fertilizer,good seed and good method.
