Description

Method for regulating and controlling flowering phase of hippeastrum rutilum

Technical Field

The application relates to the technical field of planting, in particular to a method for regulating and controlling the florescence of hippeastrum rutilum.

Background

The hippeastrum (hippeastrum hybridum) belongs to the bulbus flower of the hippeastrum of the lycopodaceae, and has large flower size, fragrance, soft and bright color, rich color and high ornamental value. The production of the cut flowers of the hippeastrum rutilum is mainly carried out in a sunlight greenhouse, and the normal flowering period is 5-6 months. The outdoor cultivation needs about 3 years from sowing to flowering and marketing, and the sunlight greenhouse cultivation can advance the flowering and marketing for 1 year, thereby obtaining better benefit. The hippeastrum belongs to perennial herb plants, and each seed ball can be continuously produced for 5-8 years. Therefore, in order to ensure the flowering quality in the next year, a series of treatments are required to be carried out on the seed balls before planting. And (3) opening the field of the cultured hippeastrum rutilum, blooming in summer and autumn, stopping growth in 10 months, stopping fertilizing and watering, and withering the overground part after blooming. Therefore, the key point is how to effectively solve the flower forcing technology by taking the hippeastrum as a new favorite for flowers in the night or high-grade potted flowers.

The current research based on the florescence control of the hippeastrum roseum is mainly focused on experimental research. The proto-yali-lingo [1] shows that the seed balls of hippeastrum rutilum are beneficial to growth of hippeastrum rutilum flower buds under the storage condition of 4-9 ℃, but the optimal storage temperature and storage time of the hippeastrum rutilum are still required to be further explored. A hippeastrum flowering phase regulation test of Lvwentao [2] shows that the seed balls are stored for 60 days at the temperature of 5-7 ℃ and have favorable influence on the leaf bud germination, the flower bud germination, the leaf unfolding rate and the flowering rate of hippeastrum. Cao Rong Xiang [3] research results on the harvesting period and pretreatment of hippeastrum indicate that the flower bud germination rate of the seedball of hippeastrum harvested in 10 months is higher than that of the seedball harvested in 9 months, but the flowering rate before the spring festival is lower than that of the seedball harvested in 9 months; the germination rate, the height and the flowering rate of the flower buds of the seedballs of the hippeastrum which is stored at low temperature are all higher than those of the seedballs which are stored at normal temperature and directly put into a pot; the seedball dormancy breaking of the hippeastrum can be effectively broken by storing for 30-60 days at the temperature of 9 ℃.

The research starts from the angle of breaking dormancy of the seed balls to regulate and control the flowering period of the hippeastrum, the storage temperature is low, the flowering rate, particularly the flowering uniformity, is not researched and explored, and how to save the storage cost and regulate and control the flowering uniformity is not considered from the angle of large-scale production. The low-temperature storage is beneficial to breaking dormancy and flower bud differentiation, but if a proper seedball treatment method is found, the seedball storage cost is reduced, the flowering uniformity of the hippeastrum is promoted, the circulation of potted flowers is accelerated, and therefore the labor cost, the rent cost and the like are saved, and the method is of great significance for large-scale production.
