Problems solved by technology

In foreign countries, Topflor has been applied to the dwarfing experiments of some flowers such as tulips, chrysanthemums, and geraniums. It was found that Topflor can obviously control the plant height when soaking the bulbs or soaking the substrate, and achieved a good dwarfing effect, but the foliar spraying The effect is generally poor
Due to different plant characteristics, the most suitable Topflor concentration and treatment methods for different plants and the resulting dwarfing effects are different, so the results obtained cannot be directly applied to other plants
It is found that the ideal dwarfing effect cannot be achieved by using the existing Topflor treatment technology on dwarf narcissus. Therefore, in view of the shortcomings of the existing technology, it is necessary to find a suitable concentration and method of Topflor for dwarfing narcissus, especially for foliar spraying. Shi's method is of great significance to overcome the existing technical bottleneck

Embodiment 1

[0023] Present embodiment relates to a kind of method of dwarfing narcissus with Topflor, described method comprises the steps:

[0024] Step 1. Dry the narcissus bulbs naturally in the shade, and select robust, disease-free and 3cm-diameter bulbs for later use;

[0025] Step 2: Soak the selected bulbs in a chlorothalonil aqueous solution with a concentration of 500 times the volume percentage and sterilize them for 60 minutes before planting, take them out, and dry them in the shade indoors for 48 hours;

[0026] Step 3: Soak the bulbs in 20ppm Topflor aqueous solution for 15 minutes, take them out, filter the water and plant them in a composite matrix, place them in a glass greenhouse without heating, and carry out conventional cultivation management to obtain dwarf dwarf narcissus plants.

[0027] Implementation effect: compared with the daffodil plants not treated by the method of the present invention, the vegetative growth of the treated daffodil plants is effectively i...

Embodiment 2

[0029] Present embodiment relates to a kind of method of dwarfing narcissus with Topflor, described method comprises the steps:

[0030] Step 1. Dry the narcissus bulbs naturally in the shade, and select robust, disease-free and 5cm-diameter bulbs for later use;

[0031] Step 2: Soak the selected bulbs with 1000 times liquid chlorothalonil aqueous solution for 30 minutes before planting, take them out, and dry them indoors for 24 hours;

[0032] Step 3: Plant the sterilized and shade-dried bulbs in the composite matrix, and spray the leaves with Topflor aqueous solution. Be that the Topflor aqueous solution of 50ppm is sprayed on leaf face with concentration, spray altogether twice, and the 1st spraying is carried out when plant height grows to 5cm, and sprays the 2nd time after 15 days. When preparing the Topflor aqueous solution, add 3 drops of Tween 20, mix well and use a watering can to make a fine mist and spray it on the leaves. Cultivate in a glass greenhouse to obtai...

Embodiment 3

[0035] Present embodiment relates to a kind of method of dwarfing narcissus with Topflor, described method comprises the steps:

[0036] Step 1. Dry the narcissus bulbs naturally in the shade, select robust, no pests and diseases, and a diameter of about 4cm. The narcissus bulbs are set aside;

[0037] Step 2: Soak the selected bulbs with 800 times liquid chlorothalonil aqueous solution for 45 minutes before planting, take them out, and dry them indoors for 36 hours;

[0038] Step 3: Plant the sterilized and shade-dried bulbs in the composite matrix, and spray the leaves with Topflor aqueous solution. Be that the Topflor aqueous solution of 30ppm is sprayed on leaf surface with concentration, spray altogether twice, and the 1st spraying is carried out when plant height grows to 7cm, sprays the 2nd time after 15 days. When preparing the Topflor aqueous solution, add 2 drops of Tween 20, mix well, and use a watering can to make a fine mist and spray it on the leaves. Cultivate...

Abstract

The invention provides a method for shortening narcissus through Topflor in the technical field of agriculture. The method comprises the steps that a narcissus seedball is selected and immersed in a Topflor aqueous solution, or foliage spraying is carried out. The seedball immersing or foliage spraying is carried out on the narcissus seedball through the Topflor aqueous solution, and the shortening effect can be achieved. After the narcissus seedball is processed, the nutrition growth of the narcissus can be obviously restrained, the plant height and the scape height are reduced, and the plants are compact, short and strong. Compared with a comparison plant, the processed plant has the advantages that the plant height and the scape height are 20-50 percent shorter than those of the comparison plant, the leaf width is increased by 15-30 percent, the leaf color is deeper, the chlorophyll content is increased by 15-40 percent, the soluble protein content is increased by 10-30 percent, the narcissus stem is improved by 10-30 percent, the narcissus color, the narcissus shape and other narcissus appreciation features are not changed, the narcissus is suitable for potting and water planting, and the method has very high practical value and economy value.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a method for dwarfing daffodils with Topflor. Background technique [0002] Narcissus (Narcissus), also known as European narcissus and Mediterranean narcissus, is a perennial bulbous flower of the genus Narcissus in the family Amaryllidaceae. It is native to the ancient Mediterranean coast and is now widely cultivated all over the world. Daffodils are solitary branches with large flowers and colorful and diverse colors, so they are loved by the world and are famous landscape plants in spring. At present, the varieties of narcissus in my country are mainly imported from abroad, and are mainly cultivated in large areas such as flower beds. Due to the high flower branches and leaves of daffodils, generally up to 40-70cm, the flower stems are herbaceous, relatively soft and easy to lodging, and the flowers are large and born on the top of the branches, the flower br...
