摘要
为筛选适宜湖南地区冬闲田种植的牧草种质,本研究以中饲3297小黑麦、牧瑶多花黑麦草和特高多花黑麦草为材料,在湖南省5个试验点(湘北站、湘东站、湘西站、湘南站、湘中站)采用大田试验对其农艺性状和抗倒伏性进行比较分析.结果表明:3个种质中,中饲3297的株高、茎粗和干草产量最高,抗倒伏性最好,特高分蘖数最多且鲜草产量最高,牧瑶叶片数最多;5个试验点中,湘西站的株高、茎粗、分蘖数、鲜草和干草产量最高,湘北站的叶片数最多;种质×试点互作效应表明,湘中站的中饲3297株高最高,湘西站的中饲3297茎粗和干草产量最高,湘西站的牧瑶分蘖数最多且鲜草产量最高,湘北站的牧瑶叶片数最多.关联度分析表明,中饲3297小黑麦生产性能最好,最适宜在湖南地区种植.
Abstract
In order to screen forage germplasm suitable for planting in Hunan province,the agronomic traits and lodging resistance were compared and analyzed by field experiment in 5 experimental sites(Xiang-bei Experimental Station,Xiangdong Experimental Station,Xiangxi Experimental Station,Xiangnan Experimental Station and Xiangzhong Experimental Station)with three forage materials of forage triticale(Zhongsi 3297)and Italian ryegrass(Muyao and Tegao)as materials.The results showed that the plant height,stem diameter and hay yield of Zhongsi 3297 were the highest among the germplasm,lodging resis-tance was the best.The tiller number and fresh yield of Tegao were the highest,and the leaf number of Muyao was the largest.The plant height,stem diameter,tiller number,fresh and hay yield were the high-est at the Xiangxi Experimental Station among the sites,and the leaf number was the largest at the Xiang-bei Experimental Station.The stem diameter and hay yield of Zhongsi 3297 were the highest at the Xiang-zhong Experimental Station,and the tiller number and fresh yield were the highest at the Xiangxi Experi-mental Station,and the leaf number of Muyao was the largest at the Xiangbei Experimental Station.The correlation analysis showed that Zhongsi 3297 triticale had the best production performance,and was the most suitable for planting in Hunan Provine.
