Embodiment 1

[0029] A kind of efficient germination method of water lily seed, comprises the following steps:

[0030] S1. Seed pretreatment: select water lily aggregate fruits with full shape, collect mature water lily seeds, and clean the seeds;

[0031] S2. Raising seedlings: put the garden soil and activated sludge into the non-woven seedling bag after mixing the weight ratio of 9:1, the height of the garden soil and the activated sludge mixture is 35% of the height of the non-woven seedling bag, and then The sand and the seeds collected in step S1 are mixed according to the weight ratio of 1200:1 and evenly spread in the non-woven seedling bag, and then the surface is covered with sand, and the sand-covered height is 2-3mm, and the non-woven seedling bag is transferred to a container. Cultivate in a water device, and the height of the water-holding device is 15cm higher than the culture system in the non-woven fabric seedling bag; the activated sludge is humic sludge with a solid cont...

Embodiment 2

[0035] A kind of efficient germination method of water lily seed, comprises the following steps:

[0036] S1. Seed pretreatment: select water lily aggregate fruits with full shape, collect mature water lily seeds, and clean the seeds;

[0037] S2. Raising seedlings: put the garden soil and activated sludge into the non-woven seedling bag after mixing the weight ratio of 5:1, the height of the garden soil and the activated sludge mixture is 50% of the height of the non-woven seedling bag, and then The sand and the seeds collected in step S1 are mixed according to the weight ratio of 1000:1 and evenly spread in the non-woven seedling bag, then sand is covered on the surface, and the sand-covering height is 2-3mm, and the non-woven seedling bag is transferred to a container. Cultivate in a water device, and the height of the water-holding device is 18cm higher than the culture system in the non-woven seedling bag; the activated sludge is humic sludge with a solid content of 2%; ...

Embodiment 3

[0041] A kind of efficient germination method of water lily seed, comprises the following steps:

[0042] S1. Seed pretreatment: select water lily aggregate fruits with full shape, collect mature water lily seeds, and clean the seeds;

[0043] S2. Raising seedlings: put the garden soil and activated sludge into the non-woven seedling bag after mixing the weight ratio of 9:1, the height of the garden soil and the activated sludge mixture is 35% of the height of the non-woven seedling bag, and then The sand and the seeds collected in step S1 are mixed according to the weight ratio of 1200:1 and evenly spread in the non-woven seedling bag, and then the surface is covered with sand, and the sand-covered height is 2-3mm, and the non-woven seedling bag is transferred to a container. Cultivate in the water device, the height of the water holding device is 15cm higher than the culture system in the non-woven seedling bag; the activated sludge is humic sludge with a solid content of 4%...

Abstract

The invention provides an efficient germination method of water lily seeds. After garden soil and activated sludge are placed on the bottom layer of a non-woven fabric seedling raising bag, a mixture of the seeds and sand is placed, after the seeds germinate, the water level is lowered in time, and the seeds are prevented from making direct contact with the activated sludge and the external environment through the physical isolation effect of the sand; the problem that the water lily sowing propagation technology has high requirements on water quality is solved in a breakthrough manner, and the current situation that the seedling rate is not high due to the influence of mosquito larvae, algae and the like after seed germination is effectively solved; by adopting the germination method disclosed by the invention, the germination rate of the water lily can be increased, and the seedling rate can be increased to 80% or above; the method is high in seedling rate, low in cost and easy to operate, seeds and soil do not need to be sterilized, and the method can be widely applied to field or indoor seedling raising.

Description

technical field [0001] The invention relates to the technical field of aquatic plant cultivation, in particular to a high-efficiency germination method of water lily seeds. Background technique [0002] Water lily (Nymphaea spp.) is a perennial aquatic plant of the genus Nymphaea in the family Nymphaeaceae. Because of its beautiful flower shape, rich color and unique fragrance, it is widely used in cut flowers, potted flowers, water landscape construction and ecological restoration projects. At the same time, water lily is known as the "Sleeping Beauty Among Flowers", and is sought after by gardening enthusiasts all over the world, and it is also the darling of domestic and international aquatic flower exhibitions. There are more than 50 native species of water lilies in the world, mainly distributed in tropical, subtropical and temperate regions, and 5 species are native to my country. After long-term selection and breeding by breeders from various countries, there are now...
