秋栽枣树好成活内容摘要:
2、厘米,质量差的剪去苗高的 1/3,并剪去一个二次枝,以利萌发新枝。 浇封冻水:入冬前浇一次封冻水,时间在 11 月下旬。 堤土防寒:11 月底至 12 月初苗木应向南压倒,以防堤土变化打对苗木须根以上造成日灼。 压倒时不能死弯,因苗木脆硬,易造成裂伤或折断。 在压倒时应先在苗木的南侧培一高 20 厘米的斜坎,将苗木轻轻压倒在斜台上,再覆 20 厘米湿润细土。 去除防寒土的时间:因枣树发芽晚,去土时间比苹果树、梨树晚,一般掌握在4 月中旬,如遇春寒,去土时间可推迟。 去土分两次完成,先去掉一层薄土,再渐渐把土全部去除,并把苗木扶直。 盖地膜:春季发芽前浇一次催芽水,再盖地膜保墒,提高地温,提高苗木成活率。 专利查询。秋栽枣树好成活
