Abstract

Abstract: Yundan 21 is a maize hybrid with inbred line WD03 as parent, inbred line N75 as parent.Through matching of improved varieties and methods experimental studies, the green and efficient cultivation techniques of Yundan 21 were summarized from the aspects of preparation before sowing, sowing, reasonable close planting, scientific fertilization, green prevention and control of diseases and pests. It is beneficial to guide farmers to carry out field production and provide theoretical basis for the large-scale promotion and planting of Yundan 21.

Key words: maize, Yundan 21, cultivation technique, green and efficient
