普通型玉米品种嫩单29饲用潜力挖掘

Exploration of Feed Potential of A Common Maize Variety Nendan 29

  • 摘要: 为进一步挖掘嫩单29的饲用价值,从而缓解饲用玉米需求,对普通型玉米品种嫩单29执行青贮品种种植及收获方式,在不同地区小区试验及青贮生产中种植。结果表明:嫩单29具有高抗倒伏、抗大斑病、丝黑穗病、茎腐病、保绿性强等特点。生物产量高,生产田平均生物产量超过3.5 t·(667 m2-1。商品品质粗蛋白属于一级、酸性洗涤纤维属于二级、中性洗涤纤维属于一级、收获时干物质31.4%,淀粉37.0%,达到“双30”选育目标。嫩单29完全可以作为青贮品种代替常规青贮品种种植,优良的抗性、商品品质有利于降低饲料青贮种植风险。

     

    Abstract: In order to further explore the feed value of Nendan 29 and relieve the demand for feed corn, the common corn variety Nendan 29 was planted and harvested as silage varieties, and planted in plot trials and silage production in different regions.The results showed that it had the characteristics of high resistance to lodging, resistance to large leaf spot, head smut, stem rot, and strong green retention.The biological yield was high, and the average biological yield of the production field exceeded 3.5 t·(667 m~2)-1.The commercial quality crude protein belonged to the first grade, the acid detergent fiber belonged to the second grade, and the neutral detergent fiber belonged to the first grade, dry matter at harvest was 31.4%,starch was 37.0%,reaching the target of “Double 30” breeding.Nendan 29 can be planted as a silage variety instead of conventional silage varieties, and its excellent resistance and commercial quality were conducive to reducing the risk of forage silage planting.
