实践证明,苹果苗木在晚秋落叶后定植,根系伤口愈合早,发生新根早,春季萌芽早,抽枝壮旺,扩冠快。但近几年各地秋栽的苗木越冬抽干现象比较严重,造成了一定损失。苗木抽干多发生在冬未春初(2月下旬—3月中下旬),除由于地温低影响根系吸水、而气温渐高苗干蒸腾失水多外。苗木质量
Practice has proved that apple seedlings planted in the late autumn after deciduous, root wound healing earlier, the occurrence of new roots early, early spring sprout, pumping strong branches, expanding the crown faster. However, in recent years, seedlings planted throughout the winter and drained more seriously and caused some losses. Drying of seedlings occurred in the early winter is not early spring (late February - late March), in addition to low temperature due to ground water absorption, and the temperature of the seedlings dry transpiration dehydration and more. Seedling quality
