Embodiment 1

[0036] Example 1: In mid-November, pick the Rhododendron chinensis fruit, air-dry it in a ventilated and dry environment at 25°C for 5 days, peel off the capsules, take 200 full seeds, and store them at -20°C for 90 days to carry out germination experiments. Disinfect with 10% sodium hypochlorite for 10 minutes, soak in distilled water at 20°C for 8 hours; then put the seeds in a germination pot, germinate in a light incubator, set the temperature at 20°C, light intensity 1500lx, light time 8 hours / day; start germination on the 10th day , the total germination number on the 17th day was 95, and the germination rate was 48%. Transplant the germinated seedlings into a flower pot with a diameter of 25 cm. The nutrient matrix in the flower pot: fine sand is 3: 1. The first seedling hardening is carried out in the light incubator. The constant temperature is set at 20 ° C, and the humidity is 75%. The light is 2500lx, the light time is 12 hours / day, and the water holding capacity o...

Embodiment 2

[0037] Example 2: In late November, pick the Rhododendron chinensis fruit, air-dry it in a ventilated and dry environment at 20°C for 6 days, peel off the capsules, take 200 full seeds, and store them at -10°C for 120 days to carry out germination experiments. Disinfect with 10% sodium hypochlorite for 10 minutes, soak in distilled water at 20°C for 10 hours; then put the seeds into a germination pot, germinate in a light incubator, set the temperature at 15°C, light intensity 1000lx, light time 5 hours / day; start to germinate on the 10th day , the total number of seeds germinated on the 17th day was 87, and the germination rate was 43.6%. Transplant the germinated seedlings into flower pots with a caliber of 25 cm. The nutrient matrix in the flower pots: fine sand is 2:1. The first seedling hardening is carried out in the light incubator, and the setting temperature is 20 ° C and the humidity is 80%. , the light is 3000lx, the light time is 10 hours / day, the water holding cap...

Embodiment 3

[0038] Example 3: In mid-November, pick the Rhododendron chinensis fruit, air-dry it in a ventilated and dry environment at 25°C for 5 days, peel off the capsules, take 200 full seeds, and store them at -20°C for 180 days to carry out germination experiments. Disinfect with 10% sodium hypochlorite for 10 minutes, soak in distilled water at 20°C for 8 hours; then put the seeds into the germination pot, germinate in the light incubator, set the temperature at 25°C, light intensity of 2000lx, and light time of 3 hours / day; start on the 11th day Germination, the total germination number of seeds on the 17th day was 70, and the germination rate was 35%; the seedlings that germinated were transplanted into a flower pot with a diameter of 25 cm, and the nutrient matrix in the flower pot: fine sand was 3: 1, and cultivated under light The first seedling hardening is carried out in the box, the temperature is set at 15°C, the humidity is 70%, the light intensity is 2000lx, the light tim...

Abstract

The invention discloses an artificial breeding method for rhododendron huadingense seedlings and belongs to the technical field of rare plant artificial breeding.The method comprises the following steps of fruit collection, seed preservation, seed germination, seedling hardening for the first time, seedling hardening for the second time and seedling transplanting.By means of the artificial breeding method, the germination rate of rhododendron huadingense seeds can be high and exceed 40%, the survival rate of the seedlings is high, the total survival rate can reach 75%, the seedlings which is successfully bred grow well, it is beneficial to protect the rare or endangered species rhododendron huadingense, and it is also beneficial to develop and utilize the plant as an ornamental flower variety.

Description

technical field [0001] The invention belongs to the technical field of artificial breeding of rare plants, and in particular relates to a method for artificial breeding of rare plant rhododendron chinensis seedlings. Background technique [0002] Rhododendron huadingense is a unique species of Rhododendron in Zhejiang Province. Rhododendron huadingense is mainly distributed in Huading Mountain, Tiantai County, Zhejiang Province, at an altitude of 750-950m. It also has a natural distribution in Dapan Mountain, Pan'an County, Zhejiang Province. narrow. The flower buds of Rhododendron chinensis are born on the top of the branches. The flowering period is April. The flowers are large and showy, the first leaves are open, the colors are diverse, and the shape is beautiful. It is a very valuable ornamental plant. [0003] The seed setting rate of Rhododendron chinensis is not low, and the number of seeds per fruit can reach up to 100; but its own breeding system has defects, such...
