越冬牧草主要在秋季9*10月间播种并开始生长, 冬季仍存活,至晚冬和早春迅速生长,到夏季即使生长 也很缓慢。越冬牧草在田间管理和利用时要注意以下事 项: 1.追肥越冬牧草若水肥充足,能显著增加分蘖,促 进幼苗健壮和根系发育,增强抗寒能力;若水肥不足则 生长不良。因此,在施足基肥的基础上,冬季和早春要追 肥,一般每次每亩7.5-10公斤尿素;另外每刈割一次, 都要追肥一次,每次可施尿素6-8公斤／亩。有些越冬牧 草如紫云英,配合施用磷钾肥则效果更佳,可显著促进 茎叶生长。
Winter forages mainly sow in September and October autumn, and begin to grow. They still survive in winter, grow rapidly in late winter and early spring, and grow slowly in summer. Winter forage management and utilization in the field should pay attention to the following matters: 1. Over-winter winter pasture fertilizer if adequate water and fertilizer, can significantly increase tillering, promote seedling robust and root development, enhance the ability of cold; if insufficient water and fertilizer poor growth. Therefore, on the basis of application of foot-based fertilizer, winter and early spring to top-dressing, generally 7.5-10 kg of urea per acre; the other for each mowing, should top-dressing time, each time urea 6-8 kg / acre. Some winter grass such as milk vetch, with the application of phosphorus and potassium is better, can significantly promote stem and leaf growth.
