Adopt the cultivation effect of the utility model LED incubator:

The experiment was carried out in a light emitting diode (LED) light incubator. The experimental material is chrysanthemum (Xiangxue) as an example.

(1) The effects of the same light intensity and different ratios of red/blue light on the growth of tissue-cultured seedlings of the chrysanthemum (Xiangxue) variety, see Table 1 for the specific test data.

Firstly, the light intensity was set to 45 μmol/m2/s, and the cultivation under fluorescent light (CK) was used as a control. The culture container is a 100ml Erlenmeyer flask. The medium is MS+sucrose 30g/L+agar 6g/L, and the pH value is adjusted to 5.8. The ratio of red/blue light in the incubator is 8:2, 7:3, 6:4 respectively, the temperature is 25°C, and the light time is 12h/d. Three plants of the test materials were inoculated in each container, and 10 containers were inoculated for each of the four treatments of each variety, a total of 30 plants. After culturing for 30 days, take out the chrysanthemum tissue culture seedlings to measure the plant height, leaf number, root number, maximum root length, dry weight of aboveground part and dry weight of underground part.

The results showed that the growth of the chrysanthemum (Xiangxue) cultured in the light-emitting diode incubator was better than that under the fluorescent light, and the optimal ratio of red and blue light was 7:3 for the chrysanthemum (Xiangxue).

(2) Effects of the same red/blue light ratio and different light intensities on the growth of chrysanthemum (Xiangxue) variety tissue culture seedlings, see Table 2 for specific test data.

Set the ratio of LED red and blue light to 7:3, under three different light intensities of 45 μmol/m ² /s, 60 μmol/m ² /s and 75 μmol/m ² /s respectively, and keep other conditions unchanged. Two days later, the chrysanthemum (Xiangxue) tissue-cultured seedlings were taken out to measure the plant height, leaf number, root number, maximum root length, dry weight of the aboveground part and dry weight of the underground part.
