Embodiment 1

[0030] Embodiment 1 is an example with the Camellia cultivar ' strong fragrance ', the present invention is described further. 'Liexiang' is one of the varieties with the largest market share. After 3 years of conventional planting, the plant height can reach more than 80cm, but the proportion of flower bud differentiation is less than 10%.

[0031] (1) Selection and potting of seedlings

[0032] In June, select 1-year-old camellia 'Liexiang' seedlings with a plant height between 15 and 20 cm and no symptoms of diseases and insect pests, and transplant them in plastic flowerpots of 16*14 cm with soilless cultivation substrates containing controlled-release fertilizers , one plant is transplanted in each pot, watered once immediately after transplanting, and the plastic flower pot is moved into a shade shed with a shading rate of 70%; the soilless culture substrate containing controlled-release fertilizer is: Add 3.0g of controlled-release fertilizer to the cultivation substra...

Embodiment 2

[0051] Except that the camellia selected for use is the hot-selling variety 'Huaxianzi' in the market and the following measures are different, all the other cultivation measures are the same as in Example 1, and will not be repeated.

[0052] (1) Selection and potting of seedlings

[0053] In July, one-year-old camellia 'Huaxianzi' seedlings with a plant height between 10 and 20 cm and no symptoms of diseases and insect pests were selected for transplanting, and the size of the plastic flowerpot was 15*13 cm. The preparation of the soilless cultivation substrate containing controlled-release fertilizer in the described plastic flower pot is: add the consumption of 2.0g controlled-release fertilizer according to every liter of soilless cultivation substrate, fully mix the controlled-release fertilizer and soilless cultivation substrate , the controlled-release fertilizer is the same as the controlled-release fertilizer described in the embodiment 1 step (1), and the soilless c...

Abstract

The invention relates to a method for promoting flower bud differentiation of young camellia and improving compactness of plants. According to the method, one-year-old camellias are transplanted, every plant of camellia is planted in a pot, by comprehensive measures including rational application of fertilizers, trimming, chemical regulation and control and the like on the camellias on the currentyear and the following year, thus, flower buds of branches of two-year-old young camellias can be differentiated, every plant has a plurality of branches, the branches are short, and light and smallcompact potting camellia new products with the height lower than 50 cm are obtained.

Description

technical field [0001] The invention belongs to the technical field of cultivation methods of woody ornamental plants, and in particular relates to a method for promoting flower bud differentiation of young camellias and improving plant compactness. Background technique [0002] Camellia, which belongs to the genus Camellia of the family Theaceae, is a famous traditional flower in my country and a world-renowned precious ornamental flower. Its bright and changeable flower colors, beautiful appearance, dense green leaves, and never withering through winter are deeply loved by people from all over the world. [0003] Potted camellias generally grow for more than 3 years before flower bud differentiation begins, and potted camellias whose flower buds are ready for the market generally take more than 4 years. The potted camellias currently on the market are mainly medium and large camellias, with a plant height of more than 70cm and mature camellias with a tree age of more than...
