摘要
苜蓿寒地栽培技术的关键是保护根颈部位不受损伤顺利越冬。其技术要点为:播前精细整地,多施磷钾肥,多翻耕减少来年草患;适当早播,采用开沟播种(深开沟、浅复土、秋季耙平)宽行播种,与禾本科牧草混播;苗期注重除草;播种当年不刈割、不放牧;每年以收“冻干草”为最好;越冬前复土、灌水;注意病虫害防治和灭鼠,以上措施并用,可显著提高苜蓿越冬率。
Protecting the crown of lucerne and keeping it undamaged is the key for the plants overwinter.The main techniques includ- ed seed bed preparation intensively,enough P and K fertilizers,early mixed sowing with grasses into deeper furrow and wider row space,but cover lightly,weeding at seedling stage,non utilization in the first year.Hay should be harvested after frozen, stubble should be covered by soil and irrigated before winter.Pests and diseases should be controlled timely.
