Embodiment Construction

[0021] From the end of May to the end of June every year, choose the vigorously growing branches of Acer palmatum (thickness 0.3-0.5cm is better) as cuttings, each cutting (8-10cm) has two nodes, and the lower part is cut at 45° , about 0.5cm from the node, the upper part is cut flat, 0.5cm from the node; all the lower leaves are cut off, and 2 complete leaves are kept on the upper part. The rooting agent is formulated with indole acetic acid at a concentration of 150 mg / l and p-hydroxybenzoic acid at a concentration of 1‰. Cut the flower mud into cuttings with an upper bottom of 3×3cm, a lower bottom of 2×2cm, and a height of 4cm, soak in water for 3 days, and change the water once a day to remove harmful substances in the flower mud. Put the soaked flower mud in the shade for 1 day, then put it into the prepared rooting agent, take it out after 10 minutes and put it into a 128 seedling tray (Taizhou Longji Plastic Industry Co., Ltd.). Insert the cuttings into the cutting bl...

Abstract

The invention discloses a cutting cultivation method for acer palmatum, which belongs to the field of horticultural production. The method comprises the following steps: inserting the cutting slips of the acer palmatum into a rooting agent cutting block which is dipped with a para-hydroxybenzoic acid containing 150 mg/l of IBA and having a mass ratio 0.001; and managing the cutting slips of the acer palmatum inserted into the rooting agent cutting block according to a full exposure cutting seedling cultivation mode, wherein calluses are formed after about 45 days; and the cutting slips of the acer palmatum inserted into the rooting agent cutting block can be transplanted after about 70 days. Tests show that the root-forming rate of the acer palmatum reaches 92 percent, the average formed root number of the cutting slips is 3.8 and an average root length is 3.5 cm. The cutting cultivation method for acer palmatum not only can quickly cultivate rare acer palmatum varieties in large scale under the condition of keeping the intrinsic excellent property of the original varieties, but also can provide a reference for plant varieties which are difficult to be cultivated by cutting, thereby having great popularization value.

Description

1. Technical field [0001] The invention relates to a preparation method for cutting propagation of Acer palmatum, belonging to the field of horticultural production. 2. Background technology [0002] Acer paimatum (Acer paimatum), also known as Yafeng, is a small deciduous tree belonging to the Aceraceae family and is a valuable ornamental tree species in urban landscapes.
