Embodiment 1

[0022] The present embodiment relates to a method for dwarf cultivation of Fragrantia japonica, and the method comprises the steps:

[0023] Step 1, dry the cedar bulbs naturally in the shade, select robust, free from diseases and insect pests, and the cedar bulbs with a circumference of about 2cm are used for later use;

[0024] In step 2, the selected bulbs are soaked in an aqueous solution of carbendazim with a volume percentage concentration of 500 times dilution before planting for 15 minutes, taken out, and dried in the shade for 24 hours;

[0025] Step 3, soak the bulbs in an aqueous solution of an exogenous growth regulator of 5000 ppm for 1 hour, take them out, drain the water, and then plant them in a glass greenhouse for routine cultivation and management to obtain Fragrantia japonica plants.

Embodiment 2

[0027] The present embodiment relates to a method for dwarf cultivation of Fragrantia japonica, and the method comprises the steps:

[0028] Step 1, dry the cedar bulbs naturally in the shade, select robust, free from diseases and insect pests, and the cedar bulbs with a circumference of about 1.8cm, for use;

[0029] Step 2, soak the selected bulbs with 1000 times of carbendazim aqueous solution for 30min before planting, take them out, and dry them in the shade;

[0030] Step 3, soak the bulbs in an aqueous solution of an exogenous growth regulator of 10,000 ppm for 3 hours, take them out, drain the water, and then plant them in a glass greenhouse for routine cultivation and management to obtain Fragrantia japonica plants.

[0031] Implementation effect: the vanilla plant obtained by the methods of Examples 1 and 2, see figure 1 As shown in the figure, the comparison chart of the growth vigor of the Fragrant japonica plant that is not processed by the method of the present ...

Embodiment 3

[0033] The present embodiment relates to a method for dwarf cultivation of Fragrantia japonica, and the method comprises the steps:

[0034] Step 1, choose and choose a robust, pest-free, and 2.5cm perimeter cedar seed bulb;

[0035] Step 2, soak the selected bulbs with 1000 times of carbendazim before planting for 15 minutes, take out the bulbs after soaking, and dry them in the shade in a well-ventilated room for one day;

[0036] Step 3, foliar spraying ethephon; directly planting the sterilized seed bulbs in the matrix, and placing them in a plastic greenhouse for conventional cultivation management; foliar spraying treatment with an ethephon solution with a concentration of 5,000 times the solution, and the first One spray is performed when the height of the plant is 10 cm after emergence, and is sprayed again after 15 days to obtain a Fragrant Shenandoah plant.

Abstract

The invention provides a dwarfing cultivation method of freesias and belongs to the technical field of agriculture. The method includes the steps of soaking bulbs in mepiquat chloride solution or ethephon solution, or spraying leafs. The mepiquat chloride solution or ethephon solution is used to treat bulbs of freesias so as to achieve dwarfing; after treatment is done using the method, nutritional growth of freesias can be significantly suppressed, plant height is decreased, the plants can be compact and dwarf and strong, and the plants blossom 5-7 days earlier; the treated plants are 1/2-1/4 as high as control plants and are generally 20-35cm in height; leaf width is increased by 20-40% and leaf color is deeper; flower ornamental characteristics such as color and pattern never change, and the method is very suitable for potting and water culture and has great application and economic value.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a method for dwarfing cultivation of S. japonica. Background technique [0002] Freesia, also known as freesia, iris, and tuberose, is a perennial bulbous flower of the genus Iridaceae, native to the Cape of Good Hope in southern Africa, and is now planted all over the world. flowers. Because of its early flowering period, elegant anthocyanin, exquisite and delicate, and fragrant, Fragrantia japonica is deeply loved by people. It is a famous cut flower and excellent potted flower, and its demand is also increasing year by year. Since the introduction of fragrant sherbet from the Netherlands in the 1980s, it has been favored by people in the domestic fresh cut flower market. At present, the varieties of Fragrantia japonica are mainly imported from abroad, mainly cut flowers. Because the stems of Fragrantia japonica are relatively soft and easy to lodging, the res...
