Embodiment 1

[0018] The bulbs of the fine Hippeastrum variety Apple Blossom were selected for scale cutting propagation.

[0019] 1. Preparation of culture medium: take garden soil and vermiculite in a ratio of 4:6 to form a culture medium, and then put it under the hot sun for 3 days for disinfection.

[0020] 2. Adjust the pH value of the culture medium: add appropriate amount of water to the culture medium to make it moist, it is better to squeeze out the water by holding it with your hand. Use 1% dilute phosphoric acid or calcium oxide to adjust the pH value of the culture medium to 6.6, then pour the prepared culture medium into a plastic bag for later use;

[0021] 3. Cutting and disinfection of the cue ball: Take the Hippeastrum cue ball with a circumference of 22cm, clean it with soapy water, remove the dry outer layer and thinner scales, put the bulb plate upwards, and cut the cue ball longitudinally in 16 points from top to bottom. And make sure that each cut part has a bulb dis...

Embodiment 2

[0025] The bulbs of the fine Hippeastrum variety Vera were selected for scale cutting propagation.

[0026] 1. Preparation of culture substrate: Take vegetable garden soil and vermiculite in a ratio of 6:4 to form a culture substrate, and then sterilize it in an oven at 120°C for 24 hours.

[0027] 2. Adjustment of the pH value of the culture medium: Add appropriate amount of water to the culture medium to make it moist. Use 1% dilute hydrochloric acid or potassium hydroxide to adjust the pH value of the culture substrate to 7.0, and then pour the prepared culture substrate into a plastic box for later use.

[0028] 3. Cutting and disinfection of the cue ball: Take the Hippeastrum cue ball with a circumference of 26cm, wash it with soapy water, remove the dry outer layer and thinner scales, put the bulb up, and cut the cue ball longitudinally from top to bottom in 16 minutes. And make sure that each cut part has a bulb disc; then these hippeastrum bulb slices are used as cutt...

Abstract

The invention discloses a cutting and breeding method of Hippeastrum bulb in the garden plant and ornamental plant domain, which is characterized by the following: adopting vegetable garden soil and vermiculite to form culture medium according to proportion; sterilizing; adjusting pH value; placing the culture medium into plastic bag or basket; sterilizing the Hippeastrum bulb after cutting to plug in the bag; culturing under dark condition; fetching the small bulb after growing on the bulb disc; planting the bulb in the excellent draining medium; growing the normal Hippeastrum under indoor temperature. The invention makes the bulb in the superior growing condition, which improves the differentiated growing and breeding rate of the cut Hippeastrum effectively.

Description

technical field [0001] The invention relates to a method for cutting and propagating Hippeastrum bulbs by cutting and propagating, which improves the induction rate of Hippeastrum cutting propagation by preparing a suitable medium. The invention belongs to agricultural biotechnology, in particular to the fields of garden plants and ornamental gardening. Background technique [0002] Hippeastrum (Hippeastrum), also known as Amaryllis, Huazhoulan, Agapanthus, etc., is a perennial herbaceous plant of the genus Amaryllis in the family Amaryllidaceae. It is native to Peru and Brazil and is widely used as an ornamental bulb flower all over the world. During the period from 1912 to 1949 in our country, there were potted plants of Hippeastrum in Nanjing, Shanghai and other places. However, it is difficult for high-grade Hippeastrum to reproduce naturally, and my country's Hippeastrum bulbs have always been dependent on imports from the Netherlands and other countries. Currently, b...
