Problems solved by technology

However, the number of Hippeastrum double-petal varieties in the domestic market is small, and the bulbs of Hippeastrum double-petal varieties imported from abroad are expensive and small in quantity, which is difficult to meet market demand. Therefore, it is of great significance to cultivate more Hippeastrum double-petal varieties to meet the needs of the domestic market.
However, in the conventional method of cultivating double-petaled Hippeastrum, because the double-petaled flowers basically do not produce pollen, the hybridization efficiency is extremely low, and the proportion of double-petaled plants in the hybrid offspring is only 3%, and the breeding period is long, which is difficult to meet Therefore, the existing technology must be improved to increase the breeding efficiency and yield of Hippeastrum double-petal plants

Embodiment 1

[0037] A method for cultivating Hippeastrum double petals is characterized in that comprising the following steps:

[0038] 1) At the beginning of October of that year, the double-petaled variety 'Hua Peacock' (see figure 1 ), Hippeastrum single-petal variety ‘Amores’ (see figure 2 ) after the bulbs are harvested, store them in a ventilated darkroom at 4°C until the end of December, then adjust the temperature in the darkroom to 20°C, and continue to store them until the end of January next year. Place in a greenhouse at 18°C ​​and water once every 3 days until the double-petal bulbs and single-petal bulbs germinate. Grow in the greenhouse at a temperature of 18°C ​​and water every 3 days until the single-petal Hippeastrum blooms in mid-March;

[0039] 2) The double-petaled bulbs removed from the pots are grown in a greenhouse with a daytime temperature of 28°C and a nighttime temperature of 20°C, and water is replenished in due course until the double-petaled Hippeastrum b...

Embodiment 2

[0060] A method for cultivating Hippeastrum double petals is characterized in that comprising the following steps:

[0061] 1) At the beginning of October of that year, after harvesting the bulbs of the double-petal variety 'Flower Peacock' and the single-petal variety Amaryllis', the bulbs were stored in a ventilated darkroom at 8°C until the end of December, and then the darkroom was adjusted When the temperature reaches 25°C, continue to store until the end of January next year, plant them in pots respectively, place the potted bulbs in a greenhouse at 25°C, and water once every 3 days until double-petal bulbs and single-petal bulbs Germinate. After the buds of the germinated double-petal bulbs break through the soil, they are removed from the pots. The single-petal bulbs continue to grow in the greenhouse at a temperature of 25°C and watered once every 3 days until mid-March. Petal Hippeastrum blooms;

Abstract

The invention provides a double-petal barbadoslily cultivation method, which includes collecting and processing seed balls, germinating the seed balls in a basin, moving the basin to a greenhouse witha daytime temperature of 28-32 DEG C and a nighttime temperature of 20-25 DEG C to grow until flowering, harvesting a large amount of double-petal barbadoslily pollen, smearing the double-petal pollen on the stigma of a single-petal barbadoslily to pollinate the single-petal barbadoslily, peeling seeds after harvesting fruits, sowing the seeds until seedlings bear seed balls, planting the seed balls in soil until flowering, and screening plants with double-petal and excellent comprehensive ornamental characteristics. In autumn, bulbs are taken out and the outer three layers of scales are stripped off to serve as explants, the explants are inoculated and cultured to obtain seed balls, and then the seed balls are planted in a greenhouse to obtain double-petal barbadoslily flowers. Using theresults of pollen production induced by high temperature from double-petal barbadoslily petals, after intercrossing with the single-petal barbadoslily, double-petal barbadoslily seed balls with excellent ornamental characteristics are bred, so that the breeding difficulty and breeding cycle of the double-petal barbadoslily are shortened, the cost of the double-petal barbadoslily is reduced, and the market demand is met.

Description

technical field [0001] The invention relates to a method for cultivating a variety of Hippeastrum double petals, and belongs to the technical field of new plant variety breeding. Background technique [0002] Amaryllis, also known as Amaryllis, is a perennial bulbous flower of the genus Amaryllis in the family Amaryllidaceae. It has the characteristics of large flowers, bright colors, and long flowering periods. The flowers and leaves of Hippeastrum have high ornamental value, and most of the common varieties are single petals. As the double-petaled Hippeastrum varieties bred abroad have gradually entered the domestic market in recent years, a small amount of its potted products are also sold. Double-petaled Hippeastrum has higher ornamental value because of its many petals, plump flower shape and novelty. The price of potted flowers is more than 50% higher than that of single-petaled varieties. However, the number of Hippeastrum double-petal varieties in the domestic marke...
