Embodiment 1

[0032] Present embodiment provides a kind of method for overwintering water lily 'Islanda', comprising the following steps:

[0033] Step 1, harvesting and cleaning of viviparous body

[0034] 'Islamida' is cultivated in the Xi'an Botanical Garden in Shaanxi Province. When the first frost comes, the viviparous bodies are harvested from the leaf nose of the leaves of the mother plant of 'Islamda' outdoors, and the sundries and rotten leaves are removed. At the same time, check the underwater place where the mother plant grows, and pull out the viviparous body that has broken away from the mother plant. The viviparous body that is fished out from the water does not need to remove the root system and leaflets that grow thereon, and the viviparous body that is harvested at the leaf nose of the mother plant blade is processed in the next step together.

[0035] Step two, the formation of dormant balls

[0036] Soak the viviparous body in water and place it outdoors under natural...

Embodiment 2

[0045] On the basis of embodiment 1, the present embodiment provides a kind of specific operation method of overwintering water lily 'Islamida', comprising the following steps:

[0046] Step 1, harvesting and cleaning of viviparous body

[0047] The time for harvesting viviparous bodies from the mother plant of water lily 'Islamda' is preferably from mid-October to early November of that year. Harvest the viviparous body from the leaf nose of the leaf of the water lily 'Islamda' mother plant outdoors, and fish out the viviparous body that has been separated from the mother plant from the water where the mother plant grows. Remove debris and rotting leaves from the viviparous body.

[0048] Step two, the formation of dormant balls

[0049] Soak the viviparous body in water and place it outdoors under natural conditions with light, so that it will gradually enter a dormant state as the outdoor temperature decreases, forming a dormant ball. The time for the viviparous body to ...

Embodiment 3

[0058] In this embodiment, water lily 'Islamida' has the characteristics of viviparous leaves, and the viviparous bodies were collected from mid-October to early November of that year, and a total of 251 viviparous bodies were harvested. Adopt above-mentioned method to form 103 small balls of dormant balls, 114 balls in dormant balls, and 34 large balls of dormant balls. In late March of the following year, take out the stored dormant balls, clean them, put them in a container, and germinate them in a 30°C incubator. The survival rate of each treatment dormancy ball was counted, and the results are shown in Table 1.

[0059] Table 1 Statistical results of the survival of dormant balls with different diameters

[0060] Classification of dormant stems

[0061] The propagules in different development states can form dormant balls of different sizes after harvesting, and after wintering and storage, the seedlings of 'Islamda' can be reproduced. It can be seen from Tabl...

Abstract

The invention belongs to the technical field of plant propagation and discloses a method for overwintering multiplication of nymphaea 'Islamorada'. The method comprises the steps of 1, harvesting a vivipary body in autumn, and clearing rotten blades and foreign matter on the vivipary body; 2, placing the vivipary body under outdoor illumination, soaking the vivipary body in water for 20-40 days to form a dormancy ball, and clearing the dormancy ball; 3, placing the clean dormancy ball at a cool and ventilating place to be dried in the shade; 4, placing the dormancy ball in wet sand of 60+/-10%, and storing the dormancy ball in the dark at 9-17 DEG C; 5, conducting pregermination propagation at the end of March the next year. Based on the biological characteristics of nymphaea 'Islamorada', the dormancy ball directly formed through the vivipary body is utilized, and survival rate is high after storage. Materials are convenient to obtain, operation is easy, cost is saved, overwintering storage and multiplication are achieved, and market requirements are met.

Description

technical field [0001] The invention belongs to the technical field of plant propagation and relates to a method for overwintering water lilies, in particular to a method for overwintering water lilies 'Isanda' through viviparous bodies directly forming dormant balls. Background technique [0002] Water lilies belong to the genus Nymphaeaceae (Nymphaeaceae) Nymphaea ) collectively referred to as plants, perennial aquatic herbaceous plants, with beautiful flowers and leaves, rich colors, long flowering period, and high ornamental value; the roots of water lilies can absorb toxic substances such as lead, mercury, and phenol in water, and are rare water purification plants; In addition, water lily also has certain medicinal value. Water lilies are mainly distributed in subtropical and temperate regions, and can be divided into cold-resistant water lilies and tropical water lilies according to their ecological characteristics. [0003] 'Islamda' ( Nymphaea 'Islamorada') is a...
