摘要
【目的】研究饲草菊苣品种和混播对干草产量和品质的影响,为高寒区饲草菊苣高效栽培提供参考。【方法】以7个饲草菊苣品种和燕麦、紫花苜蓿、红豆草为材料,开展品种和混播试验,在第一生长季菊苣莲座期进行刈割和农艺性状调查。【结果】饲草菊苣田间出苗率16.5%~31.9%,晾干干草产量220.4~322.6 kg/667m^(2)。菊苣分别与燕麦、紫花苜蓿、红豆草混播,两次刈割总干草产量分别可达462.5,410.7和459.6 kg/667m^(2),均高于菊苣单播,干草构成分别以燕麦、菊苣和菊苣为主。菊苣莲座期第1次刈割干草粗蛋白含量排序为燕麦8.85%<菊苣13.80%<红豆草15.93%<紫花苜蓿18.81%。【结论】饲草菊苣播种量300 g/667m^(2)、亩保苗数60000左右为宜,产量和品质以品种哈哈草、欧洲和佐罗相对较好,与禾草、豆草混播可起到增加产量和提升品质的双重作用。
【Objective】The aim of this study is to examine the impact of different varieties of forage chicory and mixed sowing on hay yield and quality,and to provide a basis for the efficient cultivation of for-age chicory in cold,high-altitude regions.【Method】Seven varieties of forage chicory,as well as oats,alfalfa and sainfoin,were used in variety and mixed sowing experiments.Cutting and agronomic traits were investi-gated in chicory during the rosette stage in the first growing season.【Result】The emergence rate of forage chicory in the field is between 16.5%and 31.9%,and the yield of sun-dried hay is between 220.4 and 322.6 kg/667 m^(2).In the mixed sowing treatment,the highest total hay yields for chicory/oats,chicory/al-falfa and chicory/sainfoin were 462.5,410.7 and 459.6 kg/667 m^(2),respectively,which were higher than the yields for single sowing of chicory.The hay composition was mainly oats,followed by chicory and sain-foin.During the rosette stage of chicory,the crude protein content of the first cut hay was ranked as follows:oats(8.85%),chicory(13.80%),sainfoin(15.93%),and alfalfa(18.81%).【Conclusion】The recom-mended sowing rate for forage chicory is 300 g/667 m^(2),with an expected number of seedlings of around 60000/667 m^(2).The yield and quality of the‘Hahaocao’,‘Europe’and‘Zoro’varieties are relatively good,and mixed sowing with grass and legume forages provides excellent comprehensive benefits.
