“8374”是广西畜牧研究所于1983年起,用野生多年生四倍体类玉米与一年生二倍体大刍草杂交成的多年生高产优质青刈类玉米新品种.经用根尖分裂细胞作了核型分析,其体细胞染色体数为3x=30,是三倍体青饲类玉米。“8374”适于中上水肥条件,在南方可越冬。其分蘖性、再生性强,单株年分蘖40多株,生长高度3.5米左右,可刈割4～5次,每亩栽培4500株,年产青料75D0公斤以上,比普通单株青饲玉米种年刈割一次亩产青料高3-4倍;它的干物质含粗蛋白质13.99％,比普通玉米青杆叶干物质的蛋白质(8.6％)高5.39％。杂交青饲类玉米,品质佳,属多汁饲料,经饲喂试验,适口性好,为奶、肉牛、羊、兔、鹅所喜食,也可作猪的补充青料。
“8374” is a perennial high-yielding and high-quality new type of green corn hybridized by Guangxi Institute of Animal Husbandry with wild perennial tetraploid corn and annual diploid tuber since 1983, Type analysis, the somatic chromosome number is 3x = 30, is a triploid green maize. “8374” suitable for fertilizer conditions in the water, in the south can wintering. Its tillering, strong regenerative, tillering more than 40 plants per year, height of 3.5 meters, can be cut 4 to 5 times, 4500 acres per mu cultivation, with an annual output of more than 75D0 kg of green material, The annual mowing rate of maize is 3-4 times higher than that of mowing green pea; its dry matter contains 13.99% of crude protein, which is 5.39% higher than that of common maize (8.6%). Green hybrid corn, good quality, is a succulent feed, the feeding test, palatability is good, for milk, beef cattle, sheep, rabbits, geese eat, but also for the pig’s green material supplement.
