Problems solved by technology

After picking the fruit, it is necessary to store the fruit in running water to prevent dryness and anoxic suffocation, and sow the seeds in the spring of the next year. However, this method is more troublesome and has a lower germination rate.

Embodiment Construction

[0016] Now the present invention will be further described

[0017] 1. Harvest the mature sea cauliflower fruit, keep the sea cauliflower fruit in a moist state during harvesting and transportation, and avoid the fruit from drying out;

[0018] 2. Put the sea cauliflower fruit into a 10cm×10cm nylon bag with a mesh of 1mm, and bury it in the pot with a depth of about 10cm. The substrate in the pot is a mixture of pond mud and yellow sand, so that the substrate is loose and air-permeable, and it is advisable to mix pond mud and yellow sand in a ratio of 1:1 through experiments;

[0019] 3. Put the pot with sea cauliflower fruit into the water at a depth of 30-50 cm. The water environment at this depth is relatively stable, and the temperature in the water should be detected in due course. When the temperature of the surrounding water environment is lower than 5°C, it is necessary to cover the top of the water surface with a plastic film for heat preservation. This experiment ...

Abstract

The invention relates to a method for storing seed in winter and cultivating ottelia acuminata in spring capable of improving germination rate, belonging to the field of reproduction and cultivation of living creature. The method comprises the following steps: maintaining the humid state of seed, embedding to a basin in which the substrate is loose and ventilated soil sand, soaking the basin in the water not lower than 5 DEG C for storage in winter; soaking the seed of ottelia acuminata in the water of 20-25 DEG C in the spring of the second year for about half a month; after the linear leaves and root come out in turn and the root is 3 cm in length, transplanting the seedling to a fixed planting basin and putting the basin to the water, and then transferring the seedling to a pool of 1-1.5 m in depth. The invention provides a method for transplanting the ottelia acuminata originally growing in the warm areas such as Guangdong and Yunnan to the middle and lower reaches of Changjiang River to make the same smoothly grow over the winter; the method can also maintain the fine activity of ottelia acuminata. The germination rate and the survival rate of seed of ottelia acuminate stored by the method are high; the method expands the growth area of ottelia acuminata and provides the condition for large-scale effective production and use of the ottelia acuminata.

Description

technical field [0001] The invention belongs to the field of biological propagation and cultivation, and relates to seed storage, sowing and seedling raising techniques, and more precisely relates to a method for winter storage and spring cultivation of seeds of the higher aquatic plant sea cauliflower. Background technique [0002] Sea cauliflower Ottelia acuminata (Gagnep.) Dandy is a perennial submerged plant of Hydrocharidaceae. It is a unique species in China and has been included in the list of national key protected plants (secondary). It is mainly distributed in Guangdong, Guangxi, Guizhou, Sichuan, Yunnan and other provinces Area. The leaves of sea cauliflower are basal, the leaves are wide, the leaf length can reach 20cm, and the petiole length can vary from 4-300cm with the water depth. The petals are white and the stamens are yellow. It blooms in four seasons and has a long flowering period. The general flowering period is from May to October, but it can be seen...
