Problems solved by technology

First, the rhizome is an economic organ, which will increase the cost after cutting, and the amount of seed used is large; second, a large amount of seed needs to be reserved, which is prone to rot and is easily attacked by rodents; third, although the reproduction coefficient is high, the cycle is long , unable to meet production needs
[0005] Seed propagation has become another important propagation method besides rhizome propagation due to its large reproduction coefficient and convenient source of seeds. However, under natural conditions, seeds of Chonglou need two winters to emerge, and the natural germination rate is low. Therefore, breaking the dormancy of chrysanthemum seeds and improving the germination rate of chrysanthemum seeds are key issues that need to be solved urgently in the breeding process of chrysanthemum seeds

Embodiment 1

[0047] The method for raising seedlings of Huazhonglou seeds in this embodiment comprises the following detailed steps:

[0048](1) Seed selection and pretreatment: Select the wild Huazhonglou imitation wild planting base for more than five years in advance, harvest the fruit in the middle and late October of that year, remove the shell, store it in an airtight container, and store it in a dark place. When the seed coat rots, take out the seeds and rub the red arils to reveal the milky white seeds, then let them dry naturally.

[0049] (2) The first low-temperature storage: store the seeds of Huazhonglou at 0-4°C for 30 days.

[0050] (3) The first enzyme treatment: put the Huazhonglou seeds that have undergone the first low-temperature refrigeration treatment in a solution containing 20 mg / L sorbitol and 80 mg / L helicase at a constant temperature of 1 hour at 37°C; take it out and let it dry Dry.

[0051] (4) The second low-temperature storage: the dried Huazhonglou seeds i...

Embodiment 2

[0061] The method for raising seedlings of Huazhonglou seeds in this embodiment comprises the following detailed steps:

[0062] (1) Seed selection and pretreatment: Select the wild Huazhonglou imitation wild planting base for more than five years in advance, harvest the fruit in early November of that year, remove the shell, store it in an airtight container, and store it in a dark place. When the seed coat rots, take out the seeds and rub off the red arils, revealing the milky white seeds, and let them dry naturally.

[0063] (2) The first low-temperature storage: store the seeds of Huazhonglou at 0-4°C for 35 days.

[0064] (3) The first enzyme treatment: put the seeds in 10mg / L sorbitol solution and 60ppm helicase solution at a constant temperature of 37°C for 1 hour; take them out and dry them in the air.

[0065] (4) The second low-temperature storage: the dried Huazhonglou seeds in step (3) were stored at 0-4°C for 40 days.

[0066] (5) The second enzyme treatment: ta...

Embodiment 3

[0074] This implements the high-efficiency seedling raising method of Huazhonglou, and the specific steps are as follows:

[0075] (1) Seed selection and pretreatment: Select the wild Huazhonglou imitation wild planting base for more than five years in advance, harvest the fruit in the middle and late October of that year, remove the shell, store it in an airtight container, and store it in a dark place. When the seed coat rots, take out the seeds and rub off the red arils, revealing the milky white seeds, and let them dry naturally.

[0076] (2) The first low-temperature storage: store the seeds of Huazhonglou at 0-4°C for 32 days.

[0077] (3) The first enzyme treatment: put the seeds in 30 mg / L sorbitol solution and 100 ppm helicase solution at a constant temperature of 37°C for 1 hour, then take them out and dry them in the air.

[0078] (4) The second low-temperature storage: the dried Huachonglou seeds in step (3) were stored at 0-4°C for 1 day.

[0079] (5) The second...

Abstract

The invention discloses a method for seedling paris polyphylla Smith in high efficiency, and the method comprises the steps of seed selection, pretreatment, first preservation at a low temperature, first enzyme processing, second preservation at the low temperature, second enzyme processing, sand storage, sowing and seedling maintenance. According to the seedling method, the seedling emergence cycle of the paris polyphylla Smith is shortened to 220-270 days; the emergence rate is up to more than 85%; the seedling period is greatly shortened; and the emergence rate of the paris polyphylla Smith is raised. Therefore, a foundation for breeding the paris polyphylla Smith sprouts rapidly and producing in large scale is provided.

Description

technical field [0001] The invention relates to the technical field of plant seedling cultivation, in particular to a high-efficiency seedling cultivation method of Huazhonglou. Background technique [0002] Huazhong Building (scientific name: Paris polyphylla ), also known as Aescin, belongs to Liliaceae ( Liliaceae ) of the genus Chonglou, which is a perennial herb. It has the functions of clearing heat and detoxifying, reducing swelling and relieving pain, cooling the liver and relieving convulsions. Treatment of convulsions and other diseases. [0003] Plants of the genus Pachyphylla have high medicinal value, and manual excavation is serious, and natural resources are facing exhaustion. At the same time, the seeds of Chonglou have a long dormant time and need two winters and one summer to germinate, and the natural germination rate is low. It takes about 5 to 10 years for the seeds to germinate and be used as medicine, making resource regeneration difficult. Theref...
