Embodiment 1

[0023] A method for collecting and accelerating the germination of Carex curcuma, the steps comprising:

[0024] (1) In the middle of June, select well-developed and robust Carex anctus plants in the field, then collect the seeds on the plants, remove impurities, and screen out the pure seeds of Carex anctus;

[0025] (2) Rinse the Carex angustifolia seeds obtained in step (1) with clear water at 20°C, then dry them in the air, then soak them in clear water at 24°C for 33 hours, and aerate the clear water with an aerator while soaking ;

[0026] (3) Preparation of wet sand: Mix fine sand, loess and sun-dried river bottom mud at a ratio of 1:1:1, and add distilled water for stirring. Stop adding water and stirring, wet sand is made;

[0027] (4) Place the wet sand made in step (3) in the sand storage bucket, then take out the Carex anctus sativa seeds soaked in the step (2) and bury them in the wet sand, then place the sand storage bucket in 20 days in an incubator at a temp...

Embodiment 2

[0030] A method for collecting and accelerating the germination of Carex curcuma, the steps comprising:

[0031] (1) In mid-July, select well-developed and robust Carex anctus plants in the wild, then collect the seeds on the plants, remove impurities, and screen out the pure seeds of Carex anctus;

[0032] (2) Rinse the Carex angustifolia seeds obtained in step (1) with clear water at 25°C, then dry them in the air, then soak them in clear water at 26°C for 28 hours, and aerate the clear water with an aerator while soaking ;

[0033] (3) Preparation of wet sand: Mix fine sand, loess and sun-dried river bottom mud at a ratio of 1:1:1, and add distilled water for stirring. Stop adding water and stirring, wet sand is made;

[0034] (4) Place the wet sand made in step (3) in the sand storage bucket, then take out the Carex anctus sativa seeds soaked in the step (2) and bury them in the wet sand, then place the sand storage bucket in 18 days in an incubator at a temperature of ...

Embodiment 3

[0037] A method for collecting and accelerating the germination of Carex curcuma, the steps comprising:

[0038] (1) In mid-August, select well-developed and robust Carex anctus in the field, then collect the seeds on the plant, remove impurities, and screen out the pure seeds of Carex anctus;

[0039] (2) Wash the Carex anctustum seeds obtained in step (1) with clear water at 18°C, then dry them in the air, then soak them in clear water at 25°C for 24 hours, and aerate the clear water with an aerator while soaking ;

[0040] (3) Preparation of wet sand: Mix fine sand, loess and sun-dried river bottom mud at a ratio of 1:1:1, and add distilled water for stirring. Stop adding water and stirring, wet sand is made;

[0041] (4) Place the wet sand made in step (3) in the sand storage bucket, then take out the Carex anctus sativa seeds soaked in the step (2) and bury them in the wet sand, then place the sand storage bucket in 15 days in an incubator at a temperature of 4°C;

Abstract

The invention relates to the technical field of seed breeding of carex dispalata. In a wild state, carex dispalata generates new plants mainly depending on extension of subterraneous stems; when carex dispalata are planted in landscape engineering, a manner of plant-division cultivation by digging the subterraneous stems is mainly adopted, therefore, the planting manner is high in death rate, vacant regions after death need to be filled with seedlings in the later period, and the cost of the engineering is increased; for the technical problem, the invention discloses a seed collecting and pregermination method of carex dispalata. The method mainly comprises the following steps: selection of carex dispalata plants and collection of seeds; cleaning, airing and soaking of the seeds; cold sand storage of the seeds; pregermination by stirring. The method disclosed by the invention is simple and easy in operation and low in cost, the seeds of carex dispalata processed by adopting the method can germinate about five days after seeding, and the survival rate of the seeds after 28 days is over 90%, therefore, the germination rate and the survival rate of the seeds can be greatly improved, and seedlings come out evenly and are good in growth.

Description

technical field [0001] The invention relates to the technical field of Carex flexatus breeding, in particular to a method for collecting and accelerating germination of Carex flexatus. Background technique [0002] In the wild state, Carex flexatus seeds have strong dormancy characteristics, and the germination rate and germination rate are extremely low, which has restricted the large-scale planting of Carex flexatus for a long time. [0003] In the wild state, Carex flexatus mainly produces new plants by underground stem extension, and has a strong selectivity to the environment. Changes in the local environment greatly restrict the spread of underground stems of Carex sativa, so that the expansion of its population is limited. [0004] In the landscaping project, Carex flexatus is planted, mainly by excavating underground stems and carrying out division cultivation. This method has a high mortality rate, and seedlings need to be replenished in the dead vacant areas in t...
