Embodiment 1

[0020] S1. One month before cutting, take mellow soil, raw soil and humus soil and mix them at a ratio of 1:1:1. The mellow soil and raw soil are mainly sandy soil, which needs good water permeability and is covered with a film;

[0021] S2. 3 days before the cutting, remove the film from the mixed matrix treated in step S1 by "mixing mellow soil, raw soil and humus soil at a ratio of 1:1:1, and covering with a film" and put it in a size of 12×18cm in the container bag;

[0022] S3, collecting the branches of Rhododendron azalea in the same year, and selecting the branches with green stems; pruning the branches, keeping the top stem 10cm, retaining 3 leaves, and each leaf retaining 1 / 4 of the whole blade;

[0023] S4. Take 1 gram of rooting powder and dissolve it with 100 grams of 75% alcohol, add 10 kilograms of clear water, add an appropriate amount of carbendazim for sterilization, and obtain a mixed solution, put the pruned branches into the resulting mixed solution and so...

Embodiment 2

[0028] S1. One month before cutting, take mellow soil, raw soil and humus soil and mix them at a ratio of 1:1:1. The mellow soil and raw soil are mainly sandy soil, which needs good water permeability and is covered with a film;

[0029] S2, 3-4 days before the cutting, remove the film of the above-mentioned matrix (after mixing) and put it into a container bag with a specification of 16×18cm;

[0030] S3, gather the rhododendron big tree that gives birth to branches in the same year, select the branches with green stems; 1 / 4 of the blade;

[0031] S4. Take 1 gram of rooting powder and dissolve it with 100 grams of 75% alcohol, add 10 kilograms of clear water, add an appropriate amount of carbendazim for sterilization, and obtain a mixed solution, put the pruned branches into the resulting mixed solution and soak for more than 2 hours , not exceeding 4 hours;

[0032] S5. Put the container bag containing the mixed substrate on the cutting seedling bed and pour it thoroughly ...

Embodiment 3

[0036] S1. One month before cutting, take mellow soil, raw soil and humus soil and mix them at a ratio of 1:1:1. The mellow soil and raw soil are mainly sandy soil, which needs good water permeability and is covered with a film;

[0037] S2, 3-4 days before the cutting, remove the film of the above-mentioned matrix (after mixing) and put it into a container bag with a specification of 12×18cm;

[0038] S3, collect the branches of Rhododendron azalea in the same year, select the branches with green stems; 1 / 4 of the leaves, the leaves are mainly used for photosynthesis, to promote the circulation of water and nutrients in the stem, so that the cuttings can take root quickly;

[0039] S4. Take 1 gram of rooting powder and dissolve it with 100 grams of 75% alcohol, add 10 kilograms of clear water, add an appropriate amount of carbendazim for sterilization, and obtain a mixed solution, put the pruned branches into the resulting mixed solution and soak for more than 2 hours , not ...

Abstract

The invention discloses cutting technology for rhododendron protistum. The cutting technology comprises following steps: taking and mixing mellow soil, immature soil and humus soil according to the proportion of 1 to 1 to 1 and covering the mixture by a thin film; loading a medium (after mixed) before cutting for about three to four days into a container bag by uncovering the thin film and placing the medium to a seeding bed; acquiring green (or green in white)current-year branches of rhododendron protistum, reserving top stems at the length of 10 to 12 cm, reserving 3 to 5 leaves and reserving 1 / 4 of an overall leaf for each leaf; thoroughly watering the container bag on the seeding bed by clear water prior to cutting, inserting branches processed by rooting powder into the bag, watering the branches by clear water once and watering the branches with carbendazim; setting up a small arch shed and covering the shed by utilization of the thin film, capping a sunshade net on the arch shed and maintaining temperature and humidity in the shed; and opening up the small arch shed after one month and observing a cutting condition. The cutting technology for rhododendron protistum has following beneficial effects: by reasonable selection of culture mediums and special treatment of cutting branches, the success rate of cutting reproduction for rhododendron protistum is increased.

Description

technical field [0001] The invention relates to the field of planting rhododendrons, in particular to a technique for cutting rhododendrons. Background technique [0002] Rhododendron protistum var. giganteum (Forr. exTagg) Chamberlain is an evergreen species of Rhododendron protistum in the Rhododendaceae family and a variant of Rhododendron protistum. The rhododendron tree has a thick and straight trunk, up to 30m in height, and is shade-tolerant in the young tree stage, and grows slowly.
