摘要
研究以6个小黑麦(Triticosecale wittmack)品种为试验材料,系统评估其饲草产量、营养品质以及籽粒产量和构成因素,旨在筛选适宜豫西北地区种植的高产优质品种.结果显示,供试6个小黑麦品种的饲草生产性能、营养品质和籽粒产量间均存在差异.其中,甘农2号干草产量、枝条数和粗蛋白含量最高,分别为21.49 t/hm2、933.05 × 104/hm2和11.86％;中饲1257籽粒产量和穗粒数最高,分别为6.55 t/hm2和56.00粒.小黑麦干草产量随枝条数的增加呈先增加后降低趋势;随单枝叶重和茎重的增加呈逐渐降低趋势.相关因素对籽粒产量的贡献顺序为:穗粒数＞千粒重＞枝条数.研究表明,通过综合评价甘农2号排名第一,可作为饲草型小黑麦在豫西北地区推广种植.
Abstract
The study aims to select high-yielding and high-quality triticale cultivars that are well-suited for cultivation in northwest Henan region through an evaluation of six triticale varieties(Triticosecale wittmack)in terms of forage production,quality,seed yield,and composition factors.The findings indicated noteworthy disparities among the tested varieties concerning forage production,nutritional quality,and seed yield.Notably,the'GN2'cultivar exhibited the highest hay yield(21.49 t/hm2),number of branches(9 330 500/hm2),and crude protein content(11.86％).Furthermore,'ZS1257'demonstrated the highest seed yield(6.55 t/hm2)and spiked grain count(56.00 grains).The yield of triticale varieties showed an increasing and then decreasing trend with the increase in the number of tillers,it gradually decreased with the increase in the weight of individual leaves and stems.The contribution of related factors to the grain yield was in the following order:number of grains per ear＞thousand-grain weight＞number of tillers.The study indicates that through comprehensive evaluation,'GN2'ranks first and can be promoted as a forage-type triticale for planting in the northwest Henan region.
