苹果树冬季修剪的最佳时期,应根据品种、树龄树势、生产的立地条件不同来确定,一般在1月中旬至3月上旬修剪完毕为宜。修剪过早,剪口易受冻害,形成干桩;修剪过晚,会削弱树势,耽误农时,影响产量。据试验,“雨水”至“惊蛰”为苹果树修剪的最佳时期。 一、品种不同,适宜修剪的时期不同。如红魁、黄魁、祝光等发芽较早;元帅、金冠、红玉、青香蕉等发芽较迟;国光发芽最晚。修剪时,先剪发芽早,早成熟的品种;后剪发芽晚,晚成熟的品种。
Apple tree pruning in winter the best time, should be based on species, tree age, the production of different site conditions to determine, usually in mid-January to early March pruned finished is appropriate. Pruning too early, cut mouth easily affected by frost damage, the formation of dry pile; pruning too late, will weaken the tree potential, delay farming, affecting output. According to the test, “rain” to “Jingzhe” the best time for apple tree pruning. First, different varieties, suitable for different periods of pruning. Such as Hongkui, Huang Kui, Zhu Guang and other germination earlier; Marshal, Golden Delicious, red jade, green banana and other germination later; Guoguang germination of the latest.
