Method of regulating flowering phase of Hippeastrum rutilum in south China

Abstract

The invention relates to a method of regulating flowering phase of Hippeastrum rutilum in south China. The method includes the steps of subjecting bulbs of Hippeastrum rutilum to field bulbing, cutting off leaves 3 cm from the upper portion of each bulb, reserving 3 cm from the root of each bulb to cut off residual roots, washing, sterilizing, and treating with hormones; placing the bulbs of Hippeastrum rutilum in a low-temperature dark environment at 5-9 DEG C for 12 h and then in a high-temperature dark environment at 22-25 DEG C for 12 h, and after 10 days of such alternate placement, placing in the low-temperature dark environment at 5-9 DEG C for 20 days before taking out; after low temperature treatment, transplanting the bulbs of Hippeastrum rutilum with one bulb transplanted in onepot, covering with earth, placing in open air, and treating with hormones after Hippeastrum rutilum grows leaves; pruning and performing maintaining management. The method has the advantages that thetemperature treatment time for Hippeastrum rutilum is shortened to 30 days, the whole growth period for flowering phase regulation is shortened to 2 months, and the production cycle is evidently shortened.

Description

technical field [0001] The invention relates to the field of planting technology, in particular to a method for controlling the flowering period of Hippeastrum in South China. Background technique [0002] Hippeastrum hybridum (Hippeastrum hybridum) belongs to the perennial herbaceous flowers of the Amaryllidaceae Hippeastrum genus that bloom in autumn and spring. It blooms from April to May every year. There are many horticultural varieties and rich colors. At present, it is widely cultivated in various countries in the world. Hippeastrum blooms once a year and the flowering period is short. The normal flowering time is also the time when many flowers are open, which cannot highlight its ornamental and application value. The market supply time has important economic and practical significance for promoting the healthy development of Hippeastrum industry. [0003] The existing control methods for the flowering period of Hippeastrum have defects such as immature technical me...
