收获期对不同品种青贮玉米生物产量和品质的影响
|
摘要
为研究收获期对不同品种青贮玉米生物产量和品质的影响,以京科青贮301、京科青贮516、饲玉1号、饲玉2号、鲁单256和鲁单258为试材,分别于三个不同收获期收获,对相关指标进行测定分析。结果表明:综合考虑生物产量和青贮品质,结合不同品种的农艺特性和当地气候条件,青贮玉米最佳的收获时期在Ⅱ期和Ⅲ期之间,即乳线到达籽粒中、下部。此时青贮玉米的生物产量收益最高,品质好,适口性好,易于动物消化吸收。
To study the effects of harvest time on yield and quality of different silage maize varieties, Jingkeqingzhu 301, Jingkeqingzhu 516, Siyu 1, Siyu 2, Ludan 256 and Ludan 258 were used as experimental materials and were harvested at three different time. The results showed that comprehensively considering the biological yield and quality of silage combined with the agronomic traits of different varieties and local climate conditions, the optimum harvest time of silage maize was between Ⅱ and Ⅲ stages, that was the stage starch layer reaching the middle and lower part of grain. At this stage, the highest biological yield of silage maize could be obtained with good quality, good palatability, and it was easier for animal to digest and absorb.
