Problems solved by technology

[0003]In the traditional method of cutting propagation of Camellia yunnanensis, in order to reduce water evaporation, generally only one leaf, sometimes only half a leaf is reserved for the cuttings, and the cuttings are used with higher density The sunshade net prevents the high temperature caused by sunlight radiation, so the weakening of leaf transpiration and the reduction of photosynthetic capacity will inevitably lead to a significant reduction in the plant's self-repair ability, resulting in a decrease in survival rate

Embodiment 1

[0032] Choose the mother plant of Yunnan camellia "Dahongpao", which is strong in growth, free from diseases and insect pests, and has full buds. Choose the top of the crown of the mother plant that is born in the same year, the color of the pruning branches is brown, the stem is hard, and the leaves are intact and thick. 2-3 according to 5-8cm For the standard cutting of a single bud, the upper end of the cutting is cut flat at a distance of 1cm from the bud body, and the lower end of the cutting is cut at an oblique cut at a distance of 1cm from the bud body. It must be cut with a sharp knife, which is easy to form a smooth and non-breaking cut. Two pieces are reserved for each cutting. full leaf.

[0033] After the cuttings are bundled by 10-20 plants, the base is soaked in 500ppm naphthalene acetic acid for 10 minutes.

[0034] Put 20cm thick raw red soil in the seedbed, water it thoroughly, press the row distance trace according to the width of 6cm, insert the cuttings ob...

Embodiment 2

[0043] Choose the mother plant of Yunnan camellia "Hentiangao" with strong growth, no pests and diseases, and full buds. Choose the top of the crown of the mother plant that was born in the same year, the pruning branches are brown in color, the stems are hard, and the leaves are intact and thick. Take 1—— For the standard cutting of 3 buds, the upper end of the cuttings is cut horizontally at a distance of 1 cm from the bud body, and the lower end of the cuttings is cut at a slant at a distance of 1 cm from the bud body. It must be cut with a sharp knife, which is easy to form a smooth and non-breaking cut. A complete leaf.

[0044] After the cuttings are bundled by 10-20 plants, the base is soaked in 500ppm naphthalene acetic acid for 10 minutes.

[0045] Put 20cm thick raw red soil in the seedbed, water it thoroughly, press the row distance trace according to the width of 6cm, insert the cuttings obliquely according to the distance between the plants of 5cm, the insertion d...

Embodiment 3

[0051] Choose the mother plant of Yunnan camellia "chrysanthemum petals" with strong growth, no pests and diseases, and full buds. Choose the top of the crown of the mother plant that grows in the same year, the color of the pruning branches turns brown, the stems are hard, and the leaves are complete and thick. 2-3 according to 5-8cm For the standard cutting of a single bud, the upper end of the cutting is cut flat at a distance of 1cm from the bud body, and the lower end of the cutting is cut at an oblique cut at a distance of 1cm from the bud body. It must be cut with a sharp knife, which is easy to form a smooth and non-breaking cut. Two pieces are reserved for each cutting. full leaf.

[0052] After the cuttings are bundled by 10-20 plants, the base is soaked in 500ppm naphthalene acetic acid for 10 minutes.

[0053] Put 20cm thick raw red soil in the seedbed, water it thoroughly, press the row distance trace according to the width of 6cm, insert the cuttings obliquely ac...

Abstract

The invention provides a full-exposure cuttage and propagation method of camellia reticulata. Lignified twigs with the length of 5-8cm of the current year serve as cutting wood, and are inserted in a seed bed filled with raw red soil and provided with a moisture preserving and temperature controlling device after the treatment of naphthylacetic acid or heteroauxin hormones. In the invention, the survival rate of cuttage of the camellia reticulata can be greatly improved, and the method has a better effect for some breeds (such as which are difficult to survive through cuttage (Hen tiangao, the most precious breed of camellia reticulate, and the like).

Description

Technical field: [0001] The invention belongs to a propagation method of Yunnan camellia, in particular to a cutting propagation method of Yunnan camellia under full light. Background technique: [0002] Yunnan camellia (Camellia reticulata) has the characteristics of long life, bright colors, evergreen, large flowers, and tall plants. The key factor. Conventional propagation methods are mainly based on grafting and grafting. The survival rate of traditional cutting propagation is extremely low (less than 1%), and even if rooted cuttings are occasionally seen, the quality of the root system is also very poor. Therefore, this species is rarely used. Propagation method by cuttings. Improving the survival rate of Yunnan camellia cuttings will provide the basic conditions for its industrial development. [0003] In the traditional cutting propagation method of Yunnan Camellia, in order to reduce water evaporation, generally only one leaf is kept on the cuttings, sometimes o...
