In order to effectively alleviate the imbalance of grass and livestock development caused by low forage yield,outdated cultivation techniques,and extremely short seasonal green feed in irrigation areas,a field demonstration of triticale multiple cropping silage corn was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 8 055 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.
