青苹果盆栽是果树园艺和盆景艺术的完美结合。在居室、庭院进行苹果盆景栽培,可以观花、品绿、赏果、尝鲜,常年四季情趣盎然,令人赏心悦目。然而青苹果怎么养呢?我们来看看吧。

青苹果怎么养

1、选盆原则:一般选用瓦盆,其质地疏松,外表粗糙古朴,通气排水性能良好,利于根系生长,且造价低廉。可选择口径30 cm,底径20 cm,高30 cm有排水孔的瓦盆。

2、土壤要求:土壤可就地取材,可按肥沃菜园土5份、过筛的煤渣2份、腐熟的厩肥2份、腐烂的锯末及骨粉发酵肥 1份,再加入10 g磷酸二氢钾按比例混合均匀、过筛。土壤pH值控制在5.4~6.8之间为宜。并用小瓦片将瓦盆盆底的小孔盖上,使之通气而不漏土。

3、上盆技巧:苗木最好是自育自栽,选择植株健壮、芽眼饱满、无病虫为害的嫁接苗,于3月上中旬上盆栽植,栽植时用5℃石硫合剂浸根消毒,并剪去坏死根,先把少量营养土装入盆底,放入苗木,将根系摆布均匀,埋土压实,及时浇水,即可保证成活。

4、浇水要领:盆栽苹果树的灌水次数和间隔时间,应依据季节、气候和土壤湿度的不同而定。盆栽苹果的浇水应掌握“见干见湿浇则浇透”的原则,避免天天浇水和浇半截水。萌芽期、花期、果实膨大期要及时补充水分,6月份为促进花芽分化,要适当控水,7~8月雨季要少浇水。

5、施肥要求:秋季落叶后,应将瓦盆里的表面土取出,换上新配制的疏松而肥沃的营养土,然后灌水沉实。生长期可每周浇施稀薄有机肥1次,切记量少勤施,以防烧根又便于吸收,减少肥液流失。室温度低于18℃时,应停止一切形式的追施。

6、光照要求:它原产热带美洲性喜高温多湿的半阴环境,畏寒冷,忌强光。

7、温度要求:生长适温18℃~30℃,要求空气相对湿度较高,忌盆土和环境干燥,喜温暖平和的环境,不耐酷热,畏高温,且耐寒性较差,春末夏初当环境温度超过25℃时,遮阴、宜凉爽通风、湿润半阴的环境。冬季要求环境温度不低于10℃,当室温度低于5℃时,地上部分会受到严重的冻害。一般情况下,秋末来临当环境温度降至10 ℃之前,要及时关主保温。

8、虫害预防:要勤观察防虫为主,遇虫则施药。

9、修剪方法:采用盘绕拉枝方式,抑制树体长势,促发新枝,对当年抽生的枝条进行摘心,促壮主干再发新枝。对徒长枝和竞争枝,结合拉枝进行扭梢、摘心、刻伤、环剥,可培养大量结果枝,并促使其形成花芽,达到早结果多结果的目的。

注意事项:

1、青苹果树养殖时,雨季可不用浇水或少浇水,连续降雨时还应及时排水,并将盆景移至遮雨处。

2、青苹果种植土壤酸碱度以微酸性到中性为宜,当PH值7.8以上时,易发生缺素失绿现象。
