Cuttage propagation method for bald cypress

Abstract

The invention relates to a cuttage propagation method for bald cypress. By the cuttage propagation method, time of natural propagation of bald cypress is shortened greatly, almost all seedlings grow roots in 50 days after cuttage, and the seedlings are available for transplanting after 120 days. Soil is sterilized before cuttage, so that soil transmission of wilt pathogens is prevented effectively, the survival rate of the seedlings can reach more than 95%, and seedling formation only takes about 4 months. Therefore, planting scale can be quickly expanded in a short time, branches and leaves of small seedlings planted for 4-5 years can be harvested, and branches and leaves of large seedlings planted for 3 years can be harvested.

Description

technical field

[0001] The invention belongs to the technical field of plant cultivation, and in particular relates to an artificial cutting propagation method of bald cypress. Background technique

[0002] Taxodium.distichum (Taxodium.distichum) is a tall tree of the genus Taxodium in the family Cedaraceae. It is an ancient "relict plant" and flourished from the Late Jurassic to the Early Cretaceous. Until the Miocene and Pliocene periods of the Tertiary, it was still widely distributed in North America and northern Eurasia 20 to 30 million years ago. Fossils of branches, leaves, cones and seeds of Mesozoic cypress have been found in the United States, Siberia, Russia, Heilongjiang, Jilin, Songliao Plain and Yunnan in my country. After the Quaternary glaciers, they all became extinct in Eurasia, and only survived in parts of North America and Latin America, where they have multiplied to this day. Its trunk is round and straight, and the tree height can reach 25-50 meters....

Embodiment Construction

[0029] A cutting propagation method of bald cypress, the method is as follows:

[0030] (1) Selecting branches for cuttings

[0031] Select 1-year-old branches with a length greater than 15 cm as branches for cuttings;

[0032] (2) Branch preservation and transportation methods for cuttings

[0033] 1) The branches that are cut and harvested are taken immediately. If they need to be transported or placed, they should be stored in a cool and humid place for later use; before transportation and packaging, soak the branches in clean water, pick them up immediately, and shake the water droplets on the branches lightly; Pack in plastic bags and tie the bag tightly, and it will take no more than 3 days from sealing the bag to transporting to the destination; after transporting to the destination, immediately take out the branches, stand them in a cool place, and water the ground where they are stored;

[0034] (3) Cutting seedlings and specifications

[0035] 1) Seedlings are div...
