Problems solved by technology

And there are patents related to Sequoia cutting seedlings, but most of them focus on the large-scale propagation technology of Sequoia seedlings. Issues such as skewed trunks, partial crowns, and slow growth of Sequoia cutting seedlings have been avoided or not explained clearly.
Moreover, the afforestation effect is not high when the cutting seedlings of North American Sequoia are used for afforestation.
It is not conducive to the promotion of practical application in production

Embodiment 1

[0027] A method for efficiently propagating North American redwood cutting seedlings is characterized in that it comprises the following steps:

[0028] a. Cuttings: Introduce and cultivate Sequoia seedlings with China Forest Seed Company, collect 1-year-old Sequoia Sequoia robust, no pests and diseases I level side branches, trim them into length 6cm spikes with top buds with scissors or grafting knife, and trim them The incision is smooth, flat, oval, without broken skin and splitting, and the basal leaves of 1 / 2 the length of the spike are removed; then the cuttings are first immersed in 50% carbendazim 500 times solution for 30 minutes for disinfection, and then 2000mg / L of Submerge the base of cuttings in IAA solution for 1 min;

[0029] b. Cutting seedbed: choose a plot with convenient transportation, easy irrigation, flat terrain, good drainage, light and ventilation; after the autumn harvest, carry out land preparation, deep plowing of more than 25cm, after plowing, th...

[0034] A method for efficiently propagating North American redwood cutting seedlings is characterized in that it comprises the following steps:

[0035] a. Cuttings: Introduce and cultivate Sequoia seedlings from China Forest Seed Company, collect 1-year-old Sequoia Sequoia robust, no pests and diseases I level side branches, trim them into 10cm long spikes with top buds with scissors or grafting knife, and trim them The incision is smooth, flat, oval, without broken skin and splitting, and the basal leaves of 1 / 2 the length of the spike are removed; then the cuttings are first immersed in 50% carbendazim 500 times solution for 30 minutes for disinfection, and then 2000mg / L of Submerge the base of cuttings in IAA solution for 1 min;

[0036] b. Cutting seedbed: choose a plot with convenient transportation, easy irrigation, flat terrain, good drainage, light and ventilation; after the autumn harvest, carry out land preparation, deep plowing of more than 25cm, after plowing, the s...

Embodiment 3

[0041] A method for efficiently propagating North American redwood cutting seedlings is characterized in that it comprises the following steps:

[0042] a. Cuttings: Introduce and cultivate Sequoia seedlings with China Forest Seed Company, collect 1-year-old Sequoia Sequoia robust, no I level side branches of plant diseases and insect pests, use scissors or grafting knife to trim into 8cm long spikes with top buds, trim down The incision is smooth, flat, oval, without broken skin and splitting, and the basal leaves of 1 / 2 the length of the spike are removed; then the cuttings are first immersed in 50% carbendazim 500 times solution for 30 minutes for disinfection, and then 2000mg / L of Submerge the base of cuttings in IAA solution for 1 min;

Abstract

The invention relates to a cutting seedling method for efficient propagation of North America redwoods. The cutting seedling method for efficient propagation of North America redwoods is characterized by comprising the following steps of cutting slips, cutting seedbeds, preparing light substrate containers, cuttage and transplanting. Based on the conventional cutting seedling method, combining cutting seedling of the light substrate containers, by conducting substrate allocation, cultivation on the seedbeds, unwanted sprout removing and strong seedling remaining, and other technique measures, the cutting seedling method for efficient propagation of North America redwoods has the advantages of being simple and fast to operate, low in cost, and easy in operating procedures, solves the problems of skewing, crown inclining and growing slowly in cutting seedling of the North America redwoods, and improves the survival rate of afforestation of cutting seedling of the North America redwoods, thereby improving the quality of cutting seedling plants of the North America redwoods and the afforestation effect; furthermore, the cutting seedling method for efficient propagation of North America redwoods has the advantages of being long in afforestation period, free of growth delaying periods, and suitable for popularization in actual production.

Description

technical field [0001] The invention relates to a method for efficiently propagating cutting seedlings of Sequoia chinensis. Background technique [0002] Sequoia is a huge evergreen tree of the family Sequoia, native to the mountains of the west coast of North America. It is a precious fast-growing relic tree species in the world. Sequoia is not only an excellent timber tree species, but also a beautiful landscape tree species. It is a world-renowned large-diameter tree species, with rapid growth, high yield rate, excellent material and long life span, and the volume of a single plant can reach 100m 3 . Sequoia trees are majestic and evergreen in all seasons. They are suitable for solitary or group planting by the lakeside or in the lawn in the garden. The landscape is beautiful and the momentum is extraordinary. [0003] North American redwood has a strong ability of sound insulation and heat insulation, and its large number of cell pore structures are filled with air, ...
