摘要
为有效缓解灌区饲草产量低、栽培技术落后、季节性青饲料极其短缺造成的草畜发展极不平衡现状,2020—2022年,经过小黑麦复种青贮玉米田间示范,初步探讨宁夏回族自治区引黄灌区新型牛羊饲草生产模式的可行性。结果表明,二者可进行上下茬搭配,形成复种,可实现饲草周年生产。小黑麦复种青贮玉米模式下饲用小黑麦及青贮玉米品质均达到饲用标准,同时饲用小黑麦干草产量10.5 t/hm2,青贮玉米产量54 t/hm2,综合效益较春种玉米高8 055元/hm2。该模式下饲草生物产量及品质均较高,在宁夏引黄灌区可进行推广。
In order to effectively alleviate the imbalance of grass and livestock development caused by low forage yield,outdated cultivation techniques,and extremely short seasonal green feed in irrigation areas,a field demonstration of triticale multiple cropping silage corn was conducted from 2020 to 2022,and a new type of cattle and sheep forage production model in the Yellow River irrigation area of Ningxia Province was explored.The results show that the two crops can be combined byplanting silage corn after planting triticale in autumn on Lingwu Farmto form a multiple cropping model,and the annual production of forage grass can be realized.Under the mode of multiple cropping silage corn with triticale,the quality of forage triticale and silage corn has reached the feed standard.At the same time,the hay yield of forage triticale is 10.5 t/hm2,and the yield of silage corn is 54 t/hm2.The comprehensive benefit is 8055 yuan/hm2 higher than that of spring corn.Under this model,the biological yield and quality of forage grass are high,which can be popularized in Ningxia Yellow River diversion Irrigation area.
