A method for controlling the flowering period of Hippeastrum in South China

Abstract

The invention relates to a method for regulating the flowering period of Hippeastrum in South China, comprising the following steps: selecting Hippeastrum seed bulbs to complete field pilling, cutting off leaves from the top 3 cm of the seed bulbs, cutting off excess roots from the root of the seed bulbs by 3 cm, and cleaning. Afterwards, carry out disinfection and hormone treatment; place Hippeastrum bulbs in a low-temperature and dark environment at 5-9°C for 12 hours, and then put them in a high-temperature and dark environment at 22-25°C for 12 hours. Take it out after 20 days in a low-temperature and dark environment at 9°C; after the low-temperature treatment is completed, transplant the bulbs of Hippeastrum, plant one plant of Hippeastrum in each pot, cover with soil, and place in the open air. After Hippeastrum grows leaves, perform hormone treatment; pruning and Conservation management. The treatment method of the present invention shortens the temperature treatment time of Hippeastrum to 30 days, shortens the entire growth cycle of flowering regulation to two months, and shortens the production cycle obviously.

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...
