摘要
落叶松小棚育苗是改变传统的育苗方式,变裸根露天培育为露天小棚培育。早春架设棚架,用塑料薄膜将床面覆盖,可提前化冻,提高地温,人为造成落叶松的适生环境。它可以克服北方的高寒天气,幼苗在棚内度过低温霜冻,增强了苗木的抗性。同时,由于采取了早播的方法,延长了苗木的生长期,缩短了育苗年限,使苗木当年出圃,提高苗木产量,增加经济效益。
Cultivating seedlings of larch in hut has Changed conventional cultivation.Building arbours in early spring and covering beds with plastic film can make the lant unfreezing im advance,raising land's temperature.As result,artificial environment fittable for seedlings to grow formed,so that they overcame high coldness in the North and increased coldresistance.Besides,owing to sowing time earlier than before growing stage prolonged,seedling culvivating time reduced,quality of seedlings also raised.
