Problems solved by technology

Because the branches and leaves of European narcissus are generally as high as 40-70cm, the herbaceous stems are juicy, and the flowers are larger on the top of the branches, the potted plants are easy to bend and break, which reduces the ornamental value and greatly limits the development of European narcissus.

Embodiment 1

[0027] The method comprises the steps of:

[0028] Step 1: Rinse the bulbs harvested from the field in early June with clean water and dry them in the shade, and store them in a ventilated environment avoiding direct sunlight. Select a robust European narcissus bulb with a circumference of 9-11cm and no damage by diseases and insect pests, for subsequent use;

[0029] Step 2: soak and disinfect the selected bulbs with 0.1wt% carbendazim aqueous solution for 30 minutes before planting, take them out, and dry them in the shade indoors for 48 hours;

[0030] Step 3: Plant the bulbs in pots in a uniform mixed substrate of 1 volume of peat, 1 volume of perlite, and 1 volume of river sand. When potted, the bulb must be completely covered with the substrate, and the top of the bulb should be covered with substrate 3-4cm. Immediately after planting the bulbs, irrigate the substrate with water and place them in an ordinary plastic greenhouse. During cultivation and management, it is...

Abstract

The invention belongs to the technical field of flower cultivation, and particularly relates to a cultivation method for dwarfing potted European narcissus by utilizing a growth delay agent. The method comprises the step that a paclobutrazol aqueous solution is used for treating the European narcissus to achieve dwarfing cultivation after the European narcissus sprouts. Compared with the prior art, the method has the advantages that the paclobutrazol solution is used for root irrigation or foliage spraying of the European narcissus so that the nutritional growth of the European narcissus can be remarkably inhibited, the height of plants is reduced, meanwhile, the plants are compact, short and strong, and the leaves are straight and dark green; the height of the treated plants and the scape height are 30-50% smaller than those of control plants, the leaves are darker, the chlorophyll content is increased by 15-30%, increase of the leaf width is not obvious, the flower color, the flower shape and other flower ornamental features are not changed, the potted plant effect is ideal, and the method has very good market prospects.

Description

technical field [0001] The invention belongs to the technical field of flower cultivation, and in particular relates to a cultivation method for dwarfing potted European narcissus by using a growth retarder. Background technique [0002] European Narcissus (Narcissus spp.), also known as Narcissus, Mediterranean Narcissus, is a perennial bulbous flower of the Amaryllidaceae Narcissus genus, mainly distributed in Europe, North Africa and the Mediterranean coast. European narcissus is very popular in the domestic market in recent years because of its large and colorful flowers, rich flower types, and bulbs that can bloom year after year. It is mainly used in cut flowers and potted plants. Or planted in thin forests and on the edge of flower beds. Because the flowering branches and leaves of European narcissus are generally 40-70cm high, the herbaceous stems are succulent, and the flowers are relatively large on the top of the branches, potted plants are easy to bend and break...
