Abstract:Corn for both grain and feed refers to a corn variety that can produce both grain and grass. This requires good greenness of stems and leaves when mature, high biological yield, relatively high grain yield, and is suitable for silage. In recent years, with the development of the breeding industry, the number of cattle farmers has increased. In order to ensure the supply of feed sources and achieve the purpose of farming and animal husbandry, corn varieties with both grain and feed are of great significance to the development of aquaculture. In order to screen out the corn varieties suitable for planting in eastern Gansu, we carried out comparative experiments on 8 corn varieties with both grain and fodder. We use the local main variety Xianyu 335 as a control. The experimental results showed that among the 8 maize varieties, Shendan 16, Dongdan 60 and Yuyuan 7879 had excellent comprehensive traits. It was higher than the control Xianyu 335 in terms of grain yield and biological yield. This can be promoted on a large scale in the same dry land terraces in the Longdong region. Jinsui 1 has better comprehensive traits, but its biomass is lower than that of the control, so further experiments are needed. Funong 998, Longdan 339 and Jiushi 20 have poor comprehensive traits and are not suitable for the promotion and planting of grainforage corn varieties.
