Problems solved by technology

However, it often takes more than one year to germinate young leaves by using leaf cuttings, and the use of small branch cuttings is limited by the slow germination speed of side buds. The current propagation methods have seriously restricted the speed of horticultural eucalyptus nursery.

Embodiment 1

[0018] A kind of method utilizing high temperature treatment to promote eucalyptus branching, comprises the steps:

[0019] S1. Choose a eucalyptus potted plant with normal growth and a height of 15-20 cm for use. First, adjust the heat source double-tube electric heater (rated power 1000W) to single-tube heating, place the hand-held weather station thermometer about 40cm away from one side of the electric heater, and place it at a height of 4 / 5 of the height of the yushu potted plant to measure the temperature Continuous measurement; move the hand-held weather station thermometer until the measured temperature is stable within the range of 50°C ± 0.5°C, then move the prepared eucalyptus potted plant so that the outer edge leaves on one side of the eucalyptus potted plant move to the position of the above-mentioned hand-held weather station for continuous acceptance High temperature treatment; the high temperature treatment time is set to 30min.

[0020] S2. After the high-te...

Embodiment 2

[0023] S1. Choose a eucalyptus potted plant with normal growth and a height of 15-20 cm for use. First, adjust the heat source double-tube electric heater (rated power 1000W) to double-tube heating, place the hand-held weather station thermometer about 30cm away from one side of the electric heater, and place it at a height of 4 / 5 of the height of the yushu potted plant to measure the temperature. Continuous measurement; move the hand-held weather station thermometer until the measured temperature is stable within the range of 60°C ± 0.5°C, then move the prepared eucalyptus potted plant so that the outer edge leaves on one side of the eucalyptus potted plant are moved to the position of the above-mentioned hand-held weather station for continuous acceptance High temperature treatment; the high temperature treatment time is set to 10min.

[0024] S2. After high-temperature treatment, water droplets can be seen from the outer edge leaves of Yushu near the heat source. Move the ...

Embodiment 3

[0027] S1. Choose a eucalyptus potted plant with normal growth and a height of 15-20 cm for use. First, adjust the heat source double-tube electric heater (rated power 1000W) to double-tube heating, place the hand-held weather station thermometer about 30cm away from one side of the electric heater, and place it at a height of 4 / 5 of the height of the yushu potted plant to measure the temperature. Continuous measurement; move the hand-held weather station thermometer until the measured temperature is stable within the range of 60°C ± 0.5°C, then move the prepared eucalyptus potted plant so that the outer edge leaves on one side of the eucalyptus potted plant are moved to the position of the above-mentioned hand-held weather station for continuous acceptance High temperature treatment; the high temperature treatment time is set to 20min.

[0028] S2. After the high temperature treatment, the outer edge leaves of the heated side of the eucalyptus can be seen to have obvious disc...

Abstract

The invention belongs to the field of plant physiology and flower gardening, and discloses a method for promoting the branching of crassula arborescens through high-temperature treatment. The method comprises the following steps that S1, a crassula arborescens plant growing normally is selected, high-temperature treatment is carried out on one side of the crassula arborescens plant by using a heat source at the temperature of 50-70 DEG C, and the high-temperature treatment time is set to be 5-30 minutes; and S2, after high-temperature treatment, the crassula arborescens plant is transferred to a ventilated and semi-shading environment to grow. According to the method for promoting the branching of the crassula arborescens through high-temperature treatment, the lateral bud sprouting speed of the crassula arborescens can be accelerated, the cuttage seedling raising period of the crassula arborescens is greatly shortened, the cost for breeding the crassula arborescens in gardening is reduced, and the economic benefit is improved.

Description

technical field [0001] The invention relates to the fields of plant physiology and flower gardening, in particular to a method for treating terminal buds of Eucalyptus eucalyptus with high temperature to promote the emergence of lateral buds. Background technique [0002] Yushu (Crassula arborescens (Mill.) Willd.) is a succulent plant of Crassulaceae (Crassulaceae) genus Crassula. Because of its unique leaf shape, jasper-like color and beautiful plant shape, it is very popular among plant lovers. Common potted ornamental plants. Yushu grows slowly, and the side buds sprout very slowly. The commonly used propagation method in horticulture is leaf or twig cutting propagation. However, it often takes more than 1 year to germinate young leaves by using leaf cuttings, and the use of small branch cuttings is limited by the slow emergence of lateral buds. The current propagation methods have seriously restricted the speed of horticultural eucalyptus nursery propagation. Conten...
