Problems solved by technology

However, it is very limited to obtain seedlings of Cinnamomum camphora through sexual reproduction, which cannot provide enough seedlings for Cinnamomum camphora plantation, which greatly limits the scale of Cinnamomum camphora plantation, and the development cycle of Cinnamomum camphora seeds is long and the seed yield is low , poor quality, many diseases and insect pests, the empty shell rate after fruit ripening is as high as 75%, and the seeds are oily, short-lived, difficult to store, and low in germination rate.

Embodiment

[0018] The mother tree used for the cutting of Shenshuizhang is the 6-year-old Shenshuizhang in the back mountain of the Forestry Extension Center of Jian'ou City, Fujian Province. The ABT-1 rooting powder used was provided by the Chinese Academy of Forestry Sciences.

[0019] The treatment method of spikes is as follows: select the semi-lignified green branches that grow vigorously on the upper part of the canopy, basically have no damage by diseases and insect pests, and have normal leaf color, keep half of the leaves, and leave at least 1-2 axillary buds on the top. Adopt the method of double pruning, cut the spikes with a diameter of 0.4-0.6 cm and a length of 6.0-10.0 cm, and make oblique cuts of 0.5-1.0 cm in length at the base of the back bud and front bud surface of the lower incision at the base of the spike. After the clipping is completed, 50 cuttings are used as a group and tied into a pair with rubber bands. The bases are aligned, and the bases of the bundled cutt...

Abstract

The invention discloses a cinnamomum micranthum cuttage breeding method which mainly includes the steps: cutting treatment; cutting bed treatment; seedbed management. Cutting treatment mainly relatesto cutting portions of cuttings, diameter classes of the cuttings, the lengths of the cuttings, cutting modes of bases of the cuttings, rooting treatment of the cuttings and the like. Cutting bed treatment mainly relates to selection of cutting bed media, cutting bed disinfection before cuttage, cutting modes, cutting bed treatment after cutting and the like. According to the method, the survivalrate of the cuttings of cinnamomum micranthum can reach 87% and is increased by 74% as compared with an existing traditional method.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a method for raising seedlings by cuttings of submerged camphor. Background technique [0002] Shenshui camphor is a precious broad-leaved tree species of the genus Cinnamomum lauraceae. It is named because the camphor oil contained in its leaves is heavier than water. Shenshui camphor is the fast-growing economic tree species with the highest oil content in the Lauraceae plant in my country, and it is also an intermittently distributed species in mainland China and Taiwan. Its wood fiber is long, it is an excellent raw material for papermaking, and its stem and root can extract camphor and camphor oil, which is widely used in medicine and chemical industry. It is also an excellent tree species for water conservation and landscaping. Class III key protected plants. However, it is very limited to obtain seedlings of Cinnamomum camphora through sexual reprod...
