12个谷子材料在呼和浩特地区饲草产量和成本效益分析

Evaluation of Forage Yield and Cost-benefit of 12 Millet Cultivars(Lines)in Hohhot

2018~2020年,对国内12份谷子材料进行饲草生产适应性与成本效益评价,以期筛选适宜呼和浩特地区种植的饲用谷子材料。结果表明:参试材料株高、鲜草产量和干草产量变幅分别为146.8~202.2cm、38819.40~63181.6kg/hm^(2)和10469.9~16698.2kg/hm^(2),3项指标在不同材料间存在显著差异(P<0.05);3年平均鲜草产量与株高的回归方程为:Y=-20245.917+384.250X,干草产量与株高的回归方程为:Y=-4792.872+99.097X;材料DXXM-13-2饲用品质优于蒙金谷1号;成本效益分析表明,净利润最高的是DXXM-13-2,为8712.75元/hm^(2)。综合分析表明,材料DXXM-13-2和蒙金谷1号较适宜在呼和浩特地区推广种植,是极具发展潜力的优质饲草。

In order to select the suitable forage millet for Hohhot area of Inner Mongolia,a field experiment was conducted from 2018 to 2020 to evaluate forage production adaptability and cost-benefit of 12 domestic millet cultivars.The results showed that the range of plant height,fresh and hay forage yield were 146.8~202.2cm,38819.4~63181.6kg/hm^(2)and 10469.9~16698.2kg/hm^(2),respectively,and there were significant differences in three indexes among different cultivars(P<0.05).Based on the average fresh grass yield in three years,the regression equation of fresh yield and plant height was Y=-20245.917+384.250X,and that of hay yield was Y=-4792.872+99.097X.Forage quality of DXXM-13-2 was better than that of Mengjingu No.1.Combined with cost-benefit analysis,DXXM-13-2 had the highest net profit of 8712.75 yuan/hm^(2).Comprehensive analysis showed that DXXM-13-2 and Mengjingu No.1 were more suitable for promotion and planting in Hohhot,and they were high quality forages with great development potential.
