摘　　要：[目的]为解决昭苏地区饲草饲料短缺问题提供科学依据。[方法]在伊犁昭苏马场初次引进新玉9号早熟玉米品种进行栽培,并用全株玉米调制青贮,并对青贮发酵品质及营养成分与外地产全株玉米青贮进行比较。[结果]昭苏饲料玉米的鲜草产量和干草产量分别为72 917.57和14 350.51 kg/hm2,结实率达66%。昭苏饲料玉米的水溶性碳水化合物含量为4.13%,显著高于外地饲料玉米。昭苏饲料玉米青贮的总酸和乳酸含量分别为3.40%和2.67%,p H为3.68,发酵品质明显优于外地饲料玉米青贮(P<0.05)。昭苏饲料玉米青贮中粗蛋白(CP)含量显著高于外地饲料玉米青贮,且中性洗涤纤维(NDF)含量相对较少。[结论]昭苏饲料玉米的全株鲜草产量达72 917.57 kg/hm2,且其青贮发酵品质及营养成分优于外地饲料玉米青贮。[ Objective ] The research aimed to provide scientific basis for solving the shortage problem of forage in Zhaosu region. [ Method ] Early - maturity maize Xinyu No. 9 was firstly cultivated in Zhaosu Horse Ranch and its whole plant was used to prepare the silage. The fer- mentation quality and nutritive composition of local maize silage were compared with non - local maize silage. [ Result] The whole crop fresh yield and dry yield of forage maize produced in Zhaosu region were 72 917.57 and 14 350.51 kg/hm2 respectively, and its seed setting rate reached 66%. The content of water soluble carbohydrate in the whole plant of local forage maize was 4.13% , which was significantly higher than in non-local forage maize. The contents of lactic acid and total acid of local maize silage were 2.67% and 3.40% respectively, the pH decreased to 3.68 and its fermentation quality was significantly higher than non-local maize silage. Crude protein （CP） content was higher and the neutral detergent fiber （NDF） content was relatively lower in the local maize silage. [ Conclusion] The whole crop fresh yield of forage maize produced in Zhaosu region was up to 72 917.57 kg/hm2 , and the fermentation quality and nutritional components of local maize silage were better than that of non - local maize silage.
