Problems solved by technology

The main reason is that the natural flowering period of the flowering flower is relatively short, and the supporting cultivation techniques (such as flowering period control technology, post-harvest preservation technology, etc.) related to potted or fresh-cut flowers are still immature, which seriously restricts the promotion of this excellent bulbous flower. application

Embodiment Construction

[0018] On May 25, 2011, 2 weeks after the leaves of Chrysanthemum fruticosa were completely lodged, 150 bulbs of Flos pachyrhiza with a diameter ≥ 3 cm were dug from the nursery ground, placed in an incubator at 15°C ± 1°C, and stored in the dark. Spray the bulbs with water every 15 days to keep them moist.

[0019] On August 1, September 15, November 1, and December 15, 2010, the bulbs were taken out from the incubator in 4 batches, 30 in each batch, and planted in plastic flowerpots with a diameter of 10 cm. The substrate used was peat soil: field soil = 1:1, and the substrate was sterilized and treated with 1 / 1000 carbendazim. Place the planted bulbs in an incubator at 25°C with constant temperature and dark cultivation. Spray water every two weeks to keep the soil moist.

[0020] The bulbs taken out on August 1, 2011, after growing in the incubator for 38 days, the flower buds exposed the soil layer. Turn on the light in the incubator, and after 1 week, the flowering fl...

Abstract

The invention provides a method for regulating the flowering time of Lycoris sprengeri Comes ex Baker. The method can be used in a matching technology of function development and application of Lycoris sprengeri Comes ex Baker potting or cut-flowers or the like and used in scientific research. The method comprises (1) the time of storing seed balls of the Lycoris sprengeri Comes ex Baker, (2) the conditions of storing the seed balls of the Lycoris sprengeri Comes ex Baker, (3) the mode of storing the seed balls of the Lycoris sprengeri Comes ex Baker, (4) the time of flower forcing of the Lycoris sprengeri Comes ex Baker and (5) the method for flower forcing of the Lycoris sprengeri Comes ex Baker. The flowering time of the Lycoris sprengeri Comes ex Baker is regulated by the adoption of the mode of low-temperature storing and high-temperature flower forcing, so any growth regulator does not need applying; the method is easy and convenient to implement and free from the influence of external environmental conditions, and a lot of production practice can also be carried out through the mode of cold storage refrigerating and greenhouse flower forcing. The obtained Lycoris sprengeri Comes ex Baker flowering plants can be used for ornamental potting or cut-flowers, so the method has important and far-reaching significance on deep development and widespread use of Lycoris sprengeri Comes ex Baker resources.

Description

technical field [0001] The invention relates to the control of flowering period of plants, and belongs to the technical field of garden ornamental plant cultivation. Background technique [0002] Changjinhua (Lycoris sprengeri Comes ex Baker) is a perennial herb of the genus Lycoris in the family Amaryllidaceae. The aboveground part has the habit of dormancy in summer and winter. There are bulbs underground, and the leaves are drawn in early spring. The leaves are broad and linear, and the apex is blunt. The flowering period is from mid-late July to early August. This is a rare bulb species for warm temperate regions with few flowers in summer. There are many kinds of flower types of Changjinhua, such as lily type and day lily type, and the flower colors include light lilac purple, purple red, light rose red, etc., and the top of the petals has a dreamlike blue halo. Like other plants of the Amaryllis genus, Changjinhua also has the characteristic that the flowers and le...
