AI Technical Summary

Problems solved by technology

Therefore, the Kudingcha holly seedlings used in production and planting are a mixed population with a very complex genetic background, and the agronomic and quality traits of the plants vary greatly, resulting in the inability to guarantee the yield and quality of Kudingcha products in the later stage
[0005] Kudingcha holly is a woody tree plant, and its branches have a high degree of lignification, so it is difficult to take root from cuttings in the prior art, and the rooting rate and transplanting survival rate of seedling cutting propagation are low

Embodiment 1

[0027] Embodiment 1: cutting propagation method of the present invention

[0028] Cut the semi-lignified branches of the current year on the mother plant of Kudingcha holly as cuttings, and cut the cuttings into cuttings of appropriate specifications. The length of the cuttings is about 15-20cm, and the diameter is about 0.6-1.0cm. Keep 3-4 leaves for each cutting, subtract 1 / 3 of the area of ​​each leaf and keep the petiole. Each cutting contains more than 2 axillary buds (2-4). The upper cut of the cutting is 2.0 cm above the bud, and the lower cut is 5-10 cm below the bud. The cut of the cutting is neat and unbroken. Cuttings do not use branches with a higher degree of lignification at the base or tender parts at the top.

[0029] Wash the prepared cuttings in clean water for 5 minutes, bundle about 30 cuttings into a small bundle, and then soak the bundled cuttings in 300mg / L naphthaleneacetic acid solution for more than 8 hours. The pH of the naphthaleneacetic acid solut...

Embodiment 2

[0035] Embodiment 2: the cutting method using the branches at the higher part of the lignified part of the base and the branches at the tender part of the top as cuttings

[0036] Except that the selection of cuttings is different, all the other steps and environment are the same as in Example 1.

[0037] Test results: The cuttings grew callus after 50 days of cutting seedlings, rooting was visible after 60 days, and the average root length was 4.1cm after 70 days, the rooting rate was only 48.1%, and the survival rate after transferring to the arched shed for hardening was only 43.2%.

Embodiment 3

[0038] Embodiment 3: the cutting method of different kinds and concentration hormone treatment

[0039] In addition to selecting hormones according to the type and concentration in Table 1, other steps and environments refer to Example 1 and each treatment is consistent. The test results are shown in Table 1.

Abstract

The invention relates to the technical field of agriculture, and discloses an ilex kudincha seedling cuttage reproduction method. According to the method, cutting slips are treated in naphthylacetic acid with the pH (potential of hydrogen) value of 6.0-7.0, seedlings are raised by cutting and transplanted until lateral buds on the cutting slips are germinated and root length reaches 5cm, transplanting nutrient soil is formed by adding compound fertilizers into yellow mud, river sands, coco coir and cow dung and then blending, stacking and curing the yellow mud, the river sands, the coco coir, the cow dung and the compound fertilizers, and ilex kudincha seedlings are obtained when cutting slip seedlings grow to 20-25cm. The pH value of growth hormone and the nutrient soil for transplanting and hardening the seedlings are mainly controlled, inventive process combination is performed for cutting slip preparation, hormone selection, cuttage link, seedbed management and the like, the cuttage reproduction method is effective, simple to operate, short in seedling raising period, high in rooting rate and transplanting survival rate, the obtained seedlings have higher growing power, and the shortcomings of an existing cuttage reproduction process are overcome.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a cutting propagation method for Kudingcha holly seedlings. Background technique [0002] Kudingcha Ilex (Ilex kudingcha C.J.Tseng), also known as Kudingcha, is a plant of the genus Ilex in the Ilex family. Kudingcha holly is a famous beverage plant with the same origin of medicine and food. It has a long history of drinking in my country and has been widely concerned by people for a long time. The products prepared from the buds of kudingcha holly have been exported to more than ten countries. and region. At present, the planting area of ​​Kudingcha holly in the country is about 100,000 mu, mainly distributed in the whole territory of Hainan, Yingde, Zhaoqing and Dapu in Guangdong, around Nanning, Daxin, Tiandeng, Longzhou in Guangxi, and some areas in Yunnan. . [0003] The old leaves and young buds of Kudingcha holly can be used as both tea and medicine. It has a uniqu...
