Conventional Yang cuttings nurturing more in the spring. Tongliao City in the past two years to engage in an attempt to plug the autumn seedlings, after observation that, compared with the spring planting seedlings have many advantages .1, survival rate and high seedling rate. According to the actual investigation, the survival rate of Yangshuqiu plugged seedlings was 95%, the survival rate of spring plugged seedlings was 81.5%, the seedling emergence rate of autumn plugged seedlings was 86% and the seedling emergence rate of spring plugged seedlings was 70%. 2, low cost and high efficiency. Autumn seeding nursery to be in early December irrigation a frozen water, but omitted the storage process.
