preparation example Construction

[0019] The invention provides a method for preparing dormant tubers of Australian water lilies, comprising the following steps: 1) transplanting Australian water lily seedlings into a container equipped with a matrix, and fixing them in water for the first stage of cultivation, the first stage The water level of the cultivation is 4-6cm higher than the Australian water lily seedlings, and the water level of the first-stage cultivation is 39-41cm higher than the planting pot; the temperature of the first-stage cultivation is 30-35°C; 2) adjust the water level to the highest Out of the planting pot by 8-12 cm, carry out the second-stage cultivation, the temperature of the second-stage cultivation is 23-27°C; 3) adjust the water level to 4-6 cm higher than the planting pot, and carry out the third-stage cultivation, the third-stage cultivation The temperature of cultivation is 16-23° C.; 4) After the third stage of cultivation, the water level is no longer maintained, and the wate...

Embodiment 1

[0028] Substrate composition: garden soil and Stanley's granular slow-release compound fertilizer (nitrogen: phosphorus: potassium = 25:14:12).

[0029] The lower matrix includes garden soil and Stanley's granular slow-release compound fertilizer with a mass ratio of 100:1;

[0030] Upper substrate: garden soil.

[0031] Container: Non-porous flower pot.

[0032] Place the lower substrate and the upper substrate in sequence in a non-porous flower pot with a volume ratio of 1:1.

[0033] 1) Transplant the Australian water lily seedlings into a container with a substrate, bury the substrate at a depth of 3-10cm, do not bury the new shoots in the substrate, fix them in water for the first stage of cultivation, and keep the water level higher than that of the Australian series The water lily seedlings were 5 cm long, until the final culture water level was 40 cm higher than the planting pot, and the temperature was 35° C., and cultivated for 40 to 45 days.

[0034] 2) Adjust an...

Embodiment 2

[0041] The lower matrix includes garden soil and Stanley's granular slow-release compound fertilizer with a mass ratio of 150:1; the rest of the conditions are consistent with Example 1.

[0042] See Table 2 for the growth conditions after planting, the diameter of dormant tubers, and the planting conditions of dormant tubers.

[0043] Table 2 Growth situation after planting, dormant tuber diameter, dormant tuber planting situation

[0044] Mass ratio of garden soil to slow-release compound fertilizer 150:1 Growth condition after planting Fast growing, clear water dormant tuber diameter 2.5~3.1cm Planting status of dormant tubers The number of seedlings to emerge is 2 to 3, and the seedlings are slightly easier to emerge, and the emergence time is slightly shorter.

Abstract

The invention provides a preparation method of Australian water lily dormant tubers, and belongs to the technical field of Australian water lily breeding, the preparation method comprises the following steps: 1) transplanting Australian water lily seedlings into a container filled with a matrix, fixing the container in water for first-stage culture, the water level being 4-6 cm higher than the Australian water lily seedlings; wherein the temperature is 30-36 DEG C, and the final culture water level is 40 cm higher than the planting pot; 2) adjusting the water level to be 8-12cm higher than theplanting pot, and carrying out second-stage culture at 23-27 DEG C; 3) adjusting the water level to be 4-6cm higher than the planting pot, and carrying out third-stage culture at the temperature of 16-23 DEG C; 4) after the third-stage culture, not keeping the water level any more, allowing water to naturally evaporate till leaves wither, and collecting dormant tubers. By means of the method, theAustralian water lily can be effectively promoted to rapidly form the dormant tubers, seedling breeding of the Australian water lily is promoted, and application and popularization are conducted.

Description

technical field [0001] The invention belongs to the technical field of breeding of Australian water lilies, in particular to a method for preparing dormant tubers of Australian water lilies. Background technique [0002] Australian water lilies are plants of the subgenus Anecphya under the genus Nymphaea of ​​the family Nymphaeaceae. They have erect pedicels, a single flower with a long flowering period, and rich flower colors. It is a water lily category with great potential for cut flowers. With the continuous improvement of domestic water lily breeding level, the demand for water lilies in the cut flower market is increasing, and the promotion and application of Australian water lilies has become more and more urgent. [0003] Dormant tuber is the most important propagation method of Australian water lily, but the existing dormant tuber preparation method has a low dormant tuber formation rate and takes a long time. Contents of the invention [0004] In view of this, t...
