Problems solved by technology

But the hydroponic flowers of aquatic plants are completely blank
However, the hydroponic flower production of aquatic plants must also adopt dwarf varieties, otherwise it will not be possible to produce beautifully shaped products

Embodiment 1

[0018] Embodiment 1: the selection of dwarfing agent concentration

[0019] 1) Concentration and preparation of dwarfing agent: The prepared concentration is divided into storage solution and use solution. The storage solution can be stored in a cool place for three months, and the use solution is ready to use.

[0020] The concentration and preparation method of dwarfing agent are shown in Table 1:

[0021]

[0022] 2) Dwarfing treatment method

[0023] ① Pot experiment

[0024] Four series of paclobutrazol, benzedramine, uniconazole and the control were used. According to the concentrations in the above table, two methods of spraying and root soaking were used respectively. There were 80 groups in total, and each group had ten pots of seedlings.

[0025] The amount of seedlings per pot: The amount of seedlings per pot of canna is 4 buds.

[0026] Requirements for the seedlings: The seedlings used for the test must be strong and disease-free, and the height of the plant...

Embodiment 2

[0044] Embodiment 2: the selection of dwarfing agent combination

[0045] Root Dipping Treatment with Single Dwarfing Agents and Combined Dwarfing Agents

[0046] Test 1: Soak roots in 150 ppm paclobutrazol aqueous solution for 12 hours;

[0047] Test 2: Soak roots in 80 ppm mepipectoramine aqueous solution for 12 hours;

[0048] Test 3: Soak roots in 60ppm uniconazole aqueous solution for 12 hours;

[0049] Test 4: first soak the roots with 150ppm paclobutrazol aqueous solution for 4 hours, and dry in the shade for 4 hours; then soak the roots with 80ppm aqueous solution of mebibutrazol for 4 hours, and dry them in the shade for 4 hours; then soak the roots with 60ppm aqueous solution of uniconazole for 4 hours, and dry them in the shade for 4 hours Hour;

[0050] Control: clear water treatment.

[0051] Table 5: Dwarfing effect started on March 5th (in terms of newly increased height of leaves)

[0052]

[0053] It can be seen from Table 5 that using combined dwarfin...

Embodiment 3

[0054] Embodiment 3: the selection of dwarfing agent combination

[0055] Use a single dwarfing agent or a combination of dwarfing agents to spray until the leaves are wet.

[0056] Test 1: 150 ppm paclobutrazol aqueous solution was sprayed;

[0057] Test 2: 80 ppm of benzedramine aqueous solution was sprayed;

[0058] Test 3: 60ppm uniconazole aqueous solution was sprayed;

[0059] Test 4: first spray with 150ppm paclobutrazol aqueous solution for the first time; 3 days after the first spraying, use 80ppm of amine aqueous solution for the second spraying; after 3 days from the second spraying, use 60ppm The uniconazole aqueous solution was sprayed for the third time;

[0060] Control: clear water treatment.

[0061] Table 6: Dwarfing effect started on March 5th (in terms of newly increased height of leaves)

[0062]

[0063] It can be seen from Table 6 that spraying treatment with combined dwarfing agent can significantly improve the dwarfing effect.

Abstract

The invention discloses a method for dwarfing aquatic cannas, which belongs to the field of agricultural technology. It includes the following steps: 1) select aquatic canna seeds for potting; 2) when the aquatic canna pot grows 4-5 buds of 2-3 cm, use paclobutrazol aqueous solution, benzedramine aqueous solution and uniconazole aqueous solution to soak the roots in sequence Or spray treatment and cultivate to obtain dwarf aquatic canna. The present invention sequentially treats the aquatic canna by the aqueous solution of paclobutrazol, the aqueous solution of benzylamine and the aqueous solution of uniconazole, so as to realize the dwarfing effect; and in combination with the special nutrient solution, the height of the plant can be significantly reduced, making the plant compact and stocky, and after treatment The height of the plant is 1 / 2-1 / 3 shorter than that of the control plant, the leaf color becomes darker, the width of the leaf increases by 20-40%, and the thickness increases by 10-20%.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a method for dwarfing aquatic cannas. Background technique [0002] The dwarfing technology of plants has been widely used in terrestrial plants, especially the dwarfed plants are used as the main species of landscape cultivation, such as tree bonsai, stump bonsai, flowers (such as celosia) and so on. Rice, the staple food of most people in our country, is a very typical example of successful dwarfing. In the 1950s and 1960s, the rice stalks were very long and tall, and more than 50% of the rice plants would fall down every year. The better the ears of rice grew, the heavier they were, and the easier it was to fall. After the rice stalks fell, the millet germinated in the ground. , seriously affecting the yield and quality of millet. Today's rice stalk height is only about 50-60% of the old one, and there is almost no lodging phenomenon. Although rice does not ...
