Problems solved by technology

[0003] Generally, beech trees are propagated by sowing, and the tree species required for reproduction need to be obtained from more mature mother trees. The germination rate of beech seeds is low, and the use of seeds for propagation cannot quickly alleviate the endangered situation of beech trees.

Embodiment 1

[0019] The soil matrix is ​​the mixed soil of perlite and peat soil according to the mass ratio of 3:1; the year-old branches of the three-year-old beech tree with a length of 1 cm are treated as cuttings in the rooting solution for rooting; the rooting solution is ABT6 rooting powder solution, concentration 200~300mg / L, soaking time is 5h, soaking depth is 2cm; cuttages are cut on the cutting bed for 35 days, the temperature of the cutting bed is 23-18 degrees, the humidity is 75%; the rooting rate after statistics is 87.8%.

Embodiment 2

[0021] The soil matrix is ​​a mixed soil of perlite and peat soil according to a mass ratio of 1:3; the current-year-old branches of a 1cm-long three-year-old beech tree are treated as cuttings in the rooting solution for rooting; the rooting solution is ABT6 rooting powder solution, concentration 200~300mg / L, soaking time is 5h, soaking depth is 2cm; cuttage is cuttage in cutting bed for 35 days, the temperature of cutting bed is 23-18 degree, humidity is 75%; The rooting rate after statistics is 86.8%.

Embodiment 3

[0022] Embodiment 3: the soil matrix is ​​the mixed soil of perlite and vermiculite according to the mass ratio of 1:1; the year-old branches of the three-year-old beech tree with a length of 1 cm are processed and rooted in the rooting liquid as cuttings; the rooting liquid is No. ABT6 rooting powder solution, the concentration is 200-300mg / L, the soaking time is 5h, and the soaking depth is 2cm; the cuttings are cut on the cutting bed for 35 days, the temperature of the cutting bed is 23-18 degrees, and the humidity is 75%; the rooting rate is 85.8% after statistics.

[0023] Through the method provided by the invention, the rooting rate of beech trees can be greatly improved, so as to realize rapid diffusion and propagation of beech good varieties.

Abstract

The invention discloses a cutting propagation method for zelkova schneideriana. The cutting propagation method comprises the following steps: A, selecting a soil matrix; B, taking specified branches as cutting slips to treat and root in a rooting solution; C, cutting rooted branches at specified cutting time, temperature and humidity. According to the method provided by the invention, a rooting rate of the zelkova schneideriana can be greatly improved, and further rapid diffusion and reproduction of fine zelkova schneideriana breed are realized.

Description

technical field [0001] The invention relates to a cutting propagation method of beech trees. Background technique [0002] Beech is one of the most important and precious hard broad-leaved tree species in the hills and plains of the middle and lower reaches of the Yangtze River. Beech has strong adaptability, beautiful tree shape, early autumn leaf color change period, long ornamental period, beautiful color, smoke-resistant and air-purifying, drought-resistant and barren, and less pests and diseases. It is an important autumn leaf landscape greening tree species in the Jiangnan area. Due to over-exploitation and utilization of resources, the amount of beech resources has decreased sharply and is in an endangered state. It has been listed as a second-level national key protected wild plant. [0003] Generally, beech trees are propagated by seeding, and the tree species required for reproduction need to be obtained from mature mother trees. The germination rate of beech seed...
