玉米一次性调控施肥技术是直接依据土壤肥力指标和种植作物选择肥料品种与确定最佳施肥量的定量化施肥技术,它建立在新的施肥理论基础上,实现了因土因作物选肥与定量施用,具有增产幅度大、肥料利用率高、农产品质量好、操作简单易行等优点。为了解决本地玉米品质差、产量低以及生产过程中存在的盲目施肥、施肥比例不合理等问题,笔者等在汾阳市贾家庄、栗家庄2个乡镇21个村示范推广了玉米一次性调控施肥技术,取得了良好的经济效益、社会效益和生态效益。
The one-time regulation and fertilization technology of corn is a quantitative fertilization technology that directly selects fertilizers according to soil fertility index and planting crops and determines the optimal fertilization amount. Based on the new fertilization theory, corn fertilization and quantification Application, with a large yield, fertilizer utilization, agricultural products, good quality, easy operation and so on. In order to solve the problems of poor local corn quality, low output, blind application of fertilizers and irrational application of fertilizers in the production process, the author conducted a one-time promotion of corn in 21 villages in 2 villages and towns of Jiajiazhuang and Lijiazhuang in Fenyang Control fertilization technology and achieved good economic, social and ecological benefits.
