Variety Comparison Test of Silage Corn in Aral Area

【目的】筛选并综合评价适合新疆阿拉尔地区栽培的青贮玉米品种。【方法】采用小区试验,测定9个青贮玉米品种的农艺性状、生产性能和营养成分,对其营养品质进行相对饲用价值RFV评价和灰色关联度综合评价。【结果】9个青贮玉米品种干草产量、粗蛋白(CP)、粗脂肪(EE)、酸性洗涤纤维(ADF)、中性洗涤纤维(NDF)、粗灰分(Ash)及淀粉(Str)含量均差异显著(P<0.05);其中新饲玉12号鲜草产量最高为1.19×10^(5)kg/hm^(2),NDF含量最低为51.87%;新沃1号CP含量最高为7.60%,ADF含量最低为28.53%;机玉336EE含量最高为3.16%,Ash最低为6.06%,Str含量最高为30.87%。【结论】华牧3号、机玉336、新饲玉11号和屯玉168适宜在新疆阿拉尔地区种植。

【Objective】To select silage maize varieties suitable for planting in Aral region of Xinjiang.【Methods】The nutritional components were determined in lab and the nine silage maize varieties and their nutritional quality was evaluated by RFV and grey correlation degree.【Results】The results showed that there were significant differences in hay yield,CP(Crude protein),EE(Crude fat),ADF(Acid detergent fiber),NDF(Neutral detergent fiber),ash(Crude ash)and str(Starch)contents among nine silage maize varieties(P<0.05);The fresh yield of Xinsiyu 12 was the highest up to 1.19×10^(5)kg/hm^(2),the lowest NDF content was 51.87%.CP content of Xinwo No.1 was the highest up to 7.60%,and the lowest ADF content was 28.53%.EE content of Jiyu 336 was the highest up to 3.16%,the lowest Ash content was to 6.06%,and Str content was the highest up to 30.87%.【Conclusion】According to the comprehensive evaluation of field performance and gray analysis,Huamu 3,Jiyu 336,Xinsiyu 11 and Tunyu 168 are suitable for cultivation and planting in Aral area.
