Embodiment 1

[0024] (1) In March of each year, harvest ranunculus seeds that are ripe and about to fall off from the fruit skin;

[0025] (2) Put the ranunculus seeds harvested in step (1) into a gauze bag, and after the ranunculus seeds are dry and fall off naturally, store the seeds in an environment with a temperature of 10°C and a humidity of 45%;

[0026] (3) In July of each year, seal the seeds stored in step (2) with a plastic bag, and place them at 0°C for 30 days of low-temperature pretreatment;

[0027] (4) When sowing in August every year, mix the peat substrate with water until it is moist, spread it on the seedling tray to a thickness of 10 cm, and spread the ranunculus seeds obtained in step (3) evenly on the surface of the substrate, keeping The distance between the seeds is 1 cm, and the fine sand is used to scatter naturally above the seedling tray to separate the superimposed seeds; after that, the seeds are covered with peat with a particle size of 0.08 cm, and the cover...

Embodiment 2

[0032] (1) In April of each year, harvest ranunculus seeds that are ripe and about to fall off from the fruit skin;

[0033] (2) Put the ranunculus seeds harvested in step (1) into a gauze bag, and after the ranunculus seeds are dry and fall off naturally, store the seeds in an environment with a temperature of 12°C and a humidity of 35%;

[0034] (3) In June of each year, seal the seeds stored in step (2) with a plastic bag, and place them at -0.5°C for 28 days of low-temperature pretreatment;

[0035] (4) When sowing in July every year, mix the peat substrate with water until it is moist, spread it on the seedling tray to a thickness of 8 cm, and spread the ranunculus seeds obtained in step (3) evenly on the surface of the substrate, keeping The distance between the seeds is 0.8 cm, and then the seeds are covered with peat with a particle size of 0.09 cm, and the covering thickness is 0.2 cm. After spraying water until the substrate is wet, place it in a dark room environmen...

Embodiment 3

[0040](1) In May of each year, harvest ranunculus seeds that have matured and shed from the fruit skin;

[0041] (2) Put the ranunculus seeds harvested in step (1) into a gauze bag, and after the ranunculus seeds dry and fall off naturally, store the seeds in an environment with a temperature of 15°C and a humidity of 40%;

[0042] (3) In June of each year, seal the seeds stored in step (2) with a plastic bag, and place them at 0.5°C for 25 days of low-temperature pretreatment;

[0043] (4) When sowing in August every year, mix the peat substrate with water until it is wet, spread it on the seedling tray to a thickness of 12 cm, and spread the ranunculus seeds obtained in step (3) evenly on the surface of the substrate, keeping The distance between the seeds is 1.5 cm, and the fine sand is used to scatter naturally above the seedling tray to separate the superimposed seeds; after that, the seeds are covered with peat with a particle size of 0.05 cm, and the covering thickness ...

Abstract

The invention provides a rapid seedling culture method of ranunculus asiaticus seeds, which comprises obtaining transplanted ranunculus asiaticus seedlings after seed harvest, seed storage, low-temperature pretreatment of the seeds, sowing, germination acceleration in a darkroom, greenhouse culture, seedling transplant and management. By adopting the method to culture the seedlings of the ranunculus asiaticus seeds, the emergence rate of full seeds can be over 95%, the seedlings can be tidy in 8-10 days after emergence of the seedlings, and the seedling culture cycle from seeding to field planting is 45-50 days. During the seedling culture process, the emergence rate is high, the seedlings are tidy, operation is easy in the aspects of germination acceleration, greenhouse culture, water and fertilizer management and the like, and large-scale efficient production of the ranunculus asiaticus seedlings can be carried out.

Description

technical field [0001] The invention relates to a seedling raising method, in particular to a rapid seedling raising method for ranunculus seeds, belonging to the technical field of plant breeding. Background technique [0002] Ranunculus ( Ranunculus asisticus ), also known as Persian buttercup and celery flower, is a perennial herbaceous flower of the genus Ranunculus in the family Ranunculaceae. Ranunculus is native to the Mediterranean coast and is widely planted in France, Israel and other European countries, and is currently cultivated in all countries in the world. Since the late 1990s, my country has introduced and cultivated ranunculus cut-flower varieties. It has bright and rich colors and high yields, and is deeply loved by consumers. At present, the provenances of ranunculus cut flowers and potted flowers produced in my country are all from abroad, which undoubtedly increases the cost of growers. Tissue culture propagation of ranunculus ranunculus has been suc...
