Problems solved by technology

[0006] Grafting: The grafting of golden camellia mainly adopts cutting or bud grafting of young seedlings. The survival rate of grafting is low, the workload is heavy, and it is difficult to reproduce seedlings in large quantities.
[0007] Tender cuttings: semi-lignified branches are used for cutting seedlings, the tops of the harvested branches are tender, the utilization rate is not high, the loss is large, and the probability of being damaged by diseases is high
In addition, only focusing on shading and spraying water to moisturize, is labor-intensive and time-consuming, and the cost is high and the benefit is low
[0008] To sum up, the propagation method of Camellia japonica of the prior art has the defects of waste of raw materials, labor and time-consuming, high cost and low benefit, it is difficult to realize large-scale cultivation of seedlings, and cannot meet the needs of developing Camellia japonica industry

Embodiment 1

[0065] The large-scale propagation method of the hardwood cuttings of camellia japonica of the present embodiment comprises the steps:

[0066] Step 1: Nursery Site Selection and Treatment

[0067] The nursery should be located in a sunny and leeward place with convenient transportation, the soil depth is more than 50cm, the slope is 8°, the soil is loose, well-drained, and the soil pH is 4.5.

[0068] Deep plowing was carried out in early December of that year, and the soil was prepared in February and March of the following year. Drainage ditches were excavated around the nursery and shallow ditches were excavated inside the nursery; the soil was prepared in early April, and the nursery was made into a seedbed. Wherein, the width of the drainage ditch is 40cm, and the depth is 60cm; the width of the shallow ditch is 30cm, and the depth is 30cm; There are trails with a width of 40cm.

Abstract

The invention discloses a large-scale propagation method of camellia chrysantha hard branch cuttage and belongs to the technical field of rare precious plant propagation. The method includes followingsteps: step 1, selecting and treating nursery land; step 2, selecting and disinfecting cuttage branches; step 3, cutting cuttings; step 4, performing cuttage; step 5, managing a nursery; step 6, transplanting seedlings out of the nursery for field planting. Camellia chrysantha hard branches are adopted for cuttage, survival rate of cuttage for 5 months is up to 98.8%, sprouting rate of cuttage for 8 months is up to 90.8%, average sprouting length is 28.8cm, average sprouting length of cuttage for 10 months is 55.6cm, average height of one-year-old seedlings is 28.5cm, and out-of-nursery rateis 85.6%; after being transplanted into a nutritional cup for cultivation for 7 months, survival rate is up to 97.38%, out-of-nursery rate is up to 92.24%, and seedling height reaches higher than 70cm.

Description

technical field [0001] The invention relates to a large-scale propagation method of hard branch cuttings of camellia japonica, belonging to the technical field of rare and valuable plant propagation. Background technique [0002] Camellia japonica is a rare and valuable plant in the world, and one of the eight national first-class protected plants in my country. It is known as "the giant panda in the plant kingdom" and "the queen of the tea family". Camellia japonica can not only be used as an ornamental, but also its flowers and leaves can be used to make tea and be used as medicine. It is a dual-purpose plant for medicine and food. [0003] The propagation method of Camellia japonica of prior art is to have seed seedling raising, high-altitude layering, grafting, twig cutting 4 kinds of methods, respectively has the following problems: [0004] Seedling: After the seedlings are unearthed, the stems of the seedlings are tender and vulnerable to pests and diseases, resultin...
