Problems solved by technology

Tan Ling (2014) in the cutting experiment of Cedar cedar, found that the selected rooting agent, the concentration of the solution and the treatment time of the scion had a significant impact on the cutting effect of Cedar cedar. After soaking in 200mg / L solution for 1 hour, the data of rooting rate, preservation rate, and number of adventitious roots in the cutting results were 46.80%, 68.73% and 16 respectively. It was found that compared with the previous cutting results, the cutting rooting rate was low. The reason for the analysis may be that the cutting time is selected in the season with higher temperature, and the higher temperature affects the survival rate of cuttings of seedlings

Embodiment 1

[0020] A kind of cedar cutting propagation method, the steps are as follows:

[0021] 1) Select 3# cedar clones and 011# cedar clones with good growth status and no pests and diseases as the mother trees, cut the semi-lignified branches of the current year as cuttings, and cut them horizontally according to the upper incision, and cut obliquely at the lower incision In the method of cutting, 20 cuttings of each clone are taken as a bundle, soaked in clear water for treatment.

[0022] 2) Using exogenous hormone NAA150ppm+IBA100ppm, soak cuttings for 1.5h.

[0023] 3) When cutting, use a small wooden stick to guide the hole, and insert the spikes of Cedar cedar into the cutting substrate (vermiculite: perlite: peat soil: yellow soil = 1:1:2:1) for 1 / 2-2 / 3, After the cuttage is completed, use soil to compact the fringe of the cedar fringe, and water it uniformly after the cuttage is completed.

[0024] 4) After cutting, use a shading net above the cutting pond to reduce the tr...

Embodiment 2

[0029] A kind of cedar cutting propagation method, the steps are as follows:

[0030] 1) Select 3# cedar clones and 011# cedar clones with good growth status and no pests and diseases as the mother trees, cut the semi-lignified branches of the current year as cuttings, and cut them horizontally according to the upper incision, and cut obliquely at the lower incision In the method of cutting, 20 cuttings of each clone are taken as a bundle, soaked in clear water for treatment.

[0031] 2) Using exogenous hormone NAA100ppm+IBA200ppm, soak cuttings for 1.5h.

[0032] 3) When cutting, use a small wooden stick to guide the hole, insert the spikes of Cedar cedar into the cutting matrix for 1 / 2-2 / 3, after the cutting is completed, use soil to compact around the spikes of Cedar fir, and pour water uniformly after the cutting is completed .

[0033] 4) After cutting, use a shading net above the cutting pond to reduce the transpiration of the cedar spikes, and use automatic spraying w...

Embodiment 3

[0039] A kind of cedar cutting propagation method, the steps are as follows:

[0040] 1) Select 3# cedar clones and 011# cedar clones with good growth status and no pests and diseases as the mother trees, cut the semi-lignified branches of the current year as cuttings, and cut them horizontally according to the upper incision, and cut obliquely at the lower incision In the method of cutting, 20 cuttings of each clone are taken as a bundle, soaked in clear water for treatment.

[0041] 2) Using exogenous hormone NAA50ppm+IBA100ppm, soak cuttings for 0.5h.

[0042] 3) When cutting, use a small wooden stick to guide the hole, insert the spikes of Cedar cedar into the cutting matrix for 1 / 2-2 / 3, after the cutting is completed, use soil to compact around the spikes of Cedar fir, and pour water uniformly after the cutting is completed .

[0043] 4) After cutting, use a shading net above the cutting pond to reduce the transpiration of the cedar spikes, and use automatic spraying wa...

Abstract

The invention discloses a cryptomeria fortunei cutting propagation method which includes step 1) of performing cutting pretreatment; step 2) of adopting exogenous hormones NAA 50-150 ppm + IBA 100-300ppm, and soaking cuttings 0.5-1.5 h; step 3) of performing cutting, and step 4) of performing management after cuttings. According to the cryptomeria fortunei cutting propagation method, tests provethat under the conditions of adopting the exogenous hormones NAA 150 ppm + IBA 100 ppm to soak the cuttings for 1.5 h, the cryptomeria fortunei cutting rooting rate can reach 98.33%, root growth can be promoted while the cutting survival rate is improved, the method is simple and practical, and reliable nursery stock sources are provided for the construction of fast-growing and high-yield forestsof cryptomeria fortunei.

Description

technical field [0001] The invention belongs to the technical field of plant cuttings, and in particular relates to a method for propagating cedar cuttings. Background technique [0002] Cedar is a genus in the family Taxaceae. Plant taxonomists believe that the Cryptomeria fortunei can be divided into two species, namely Cryptomeria fortunei and C.japonica. The growth height of cedar can reach about 40m, and the diameter at breast height can reach more than 2m. Cedar is an evergreen tree, and it is also cultivated in southern Jiangsu, Zhejiang, Henan, Jiangsu, Shandong, Anhui and other provinces, and the growth of Cedar is good. The general growth height of cedar is: the leeward sunny place at an altitude of 400m ~ 1400m, often mixed with some broad-leaved tree species such as Castanopsis eyrei Tutch. 14~19℃, the average temperature in January is above 0℃. Cedar has fast growth speed, light and soft material, straight texture, high strength, strong corrosion resistance,...
