近年来,广玉兰大树(胸径8厘米以上)陆续进城上路,进厂入院,成为园林绿化的首选树种,但移植难度大,要求技术高。那么怎样操作能提高成活率呢? ▲移植时间广玉兰喜温暖湿润气候,春季移植宜在3月中旬至4月下旬,秋季宜在10月上旬至11月下旬,气温在0℃以下时最好不移植。▲起树技术①起球为保证其根系的完整,根据广玉兰的根系生长特点,土球的球径与地径之比以10:1左右为宜。如地径10厘米,球径应控制在100厘米左右一起土深度60～100厘米。②包装。用草绳分4层包装:第一层从土球中下部向上环绕10～15圈,逐圈拉紧,俗称“打腰箍”;第二层,整个土球套上一层麻袋片或纺织袋,然后按顺时针方向用草绳倾斜环绕逐圈包装整个土球;第三层,按逆时针方向倾斜环绕包装整个土球;最后一层,像第一层一样从
In recent years, Magnolia grandiflora (DBH more than 8 cm) one after another into the city on the road, into the plant admission, become the preferred tree species of landscaping, but transplantation difficult, requiring high technology. So how can the operation increase the survival rate? ▲ Transplant time Magnolia hi warm and humid climate, spring transplantation should be in mid-March to late April, autumn should be in early October to late November, the best temperature below 0 ℃ Do not transplant. ▲ from the tree technology ① pilling in order to ensure the integrity of its roots, according to Magnolia root growth characteristics, the diameter of the earth ball and the diameter of the ratio of about 10: 1 is appropriate. If the diameter of 10 cm, the ball diameter should be controlled at about 100 cm soil depth of 60 to 100 cm. ② packaging. The grass rope is divided into 4 layers of packaging: the first layer from the lower part of the soil around the ball 10 to 15 laps, tightened by the circle, commonly known as “hit waist hoop”; the second layer, the entire soil put a layer of sacks or textile Bag, and then clockwise with a straw ropes around the circle by ring packaging the entire soil ball; the third layer, counterclockwise wrapped around the entire tilt around the earth; the last layer, like the first floor from the
