摘要
为了缓解当地牧草需求紧张的现状。2023年在环县进行巨菌草引种试验,探索巨菌草在庆阳地区的适宜种植模式。试验分别设置120 cm 80 cm、80 cm 60 cm、60 cm 40 cm 3种种植密度进行试验,每组进行3个重复,测定其生产特性及营养物质含量。当巨菌草种植密度在80 cm 60 cm时,其在生长150 d后干物质、粗蛋白、粗脂肪、钙、磷、钾、镁等营养元素的含量分别达到27.45%、8.40%、1.21%、0.21%、0.26%、2.80%和0.20%,达到同时期青贮玉米的营养水平,其鲜草产量达到209 t/hm^(2)。种植巨菌草每公顷收益34725元,比种植青贮玉米的收益高15525元。巨菌草在环县推广前景广阔。
To alleviate the current situation of local forage demand.The introduction experiment of Pennisetumgiganteum z.x.lin.was conducted in Qing-yang regions during 2023.The suitable planting models of Pennisetumgiganteumz.x.lin.in Qing-yang regions were explored.The planting densities of 120 cm 80 cm,80 cm 60 cm,and 60 cm 40 cmwere respectively assigned to three groups,with each group having three replicates conducted to determine their production characteristics and nutrient content.When the planting density was 80 cm 60 cm,the content of DM、CP、EE、GA、P、K、MGof Pennisetumgiganteumz.x.lin.was 27.45%、8.40%、1.21%、0.21%、0.26%、2.80%and 0.20%.After 150 d of growth,which reached the nutrient level of silagemaize in the same period.The yield of Pennisetum sp.was 209 t/hm^(2).The income value of planting Pennisetum giganteumz.x.lin is 34725 yuan per hectare,which is 15525 yuan higher than the income of planting silage maize.The spread planting of Pennisetum giganteum z.x.lin.has broad prospects in Huanxian.
