摘要
试验采取收获饲用小黑麦后复种青贮玉米的栽培方式,同时进行氮素调控,研究不同施氮量和氮肥类型对复种方式下饲用小黑麦和青贮玉米产量及饲用品质的影响。结果表明,纯氮用量100kg/hm2的缓释氮肥处理小黑麦产量和品质显著优于其他用量尿素处理;青贮玉米生育期较长,中期追肥效果更好,其中,在一定地力基础上,N3(前茬小黑麦纯氮用量150kg/hm2,后茬青贮玉米纯氮用量200kg/hm2)处理青贮玉米产量和品质最优。
Through planting silage corn after harvesting triticale, effects of N levels and nitrogen fertilizer types on yield and feeding quality in multiple cropping of triticale and silage corn was investigated. The results indicated that the treatment of slow-release nitrogen fertilization at the N level of 100kg/hm2 in triticale had higher yield and feeding quality than the other treatments of urea, and because of the long growth period of silage corn, the fertilization at the medium term was better. On the basis of certain fertility, the best silage corn yield and quality was found in treatment N3 （triticale with pure nitrogen of 150kg/hm2, and subsequently silage corn with pure nitrogen of 200kg/hm2 ）
