Cutting cultivation method for acer palmatum

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.

AI Technical Summary

Problems solved by technology

[0004] Acer palmatum is mainly propagated by seed sowing, but the flowering cycle of Acer palmatum is long, and the seeds need sand storage and other technical links, and the rapid popularization and application of new varieties such as famous and high-quality is limited

In order to expand the reproduction coefficient of excellent strains as soon as possible and expand the number of seedlings, cutting propagation is an effective technical means. Because it is very difficult to propagate Acer palmatum using conventional cutting methods, so far, there has been no relevant Successful reports of maple cuttings
