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] Example 1: 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] There are four series of paclobutrazol, meclobutan, uniconazole and the control. According to the concentration in the above table, two methods of spraying and root soaking are used respectively, a total of 80 groups, each with ten pots of seedlings.

[0025] Planting seedlings per pot: Canna canna seedlings are 4 buds per pot.

[0026] Requirements for seedlings: The seedlings used for the test must be robust, disease-free, and the plant height and stem thickness should be the same among the pots.

[0027] Requirements ...

Embodiment 2

[0044] Example 2: Selection of dwarfing agent combination

[0045] Use single dwarfing agent and combined dwarfing agent for root soaking treatment

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

[0047] Test 2: Root immersion in 80 ppm aqueous solution of meepamine for 12 hours;

[0048] Test 3: Soaking the roots with 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 Meconazole for 4 hours and dry for 4 hours in the shade; then use 60ppm Uniconazole aqueous solution to soak the roots for 4 hours and dry for 4 hours in the shade. hour;

[0050] Control: clean water treatment.

[0051] Table 5: The dwarfing effect starts on March 5 (with the newly increased height of the leaves)

[0052]

[0053] It can be seen from Table 5 that the use of combined dwarfing agent for root soak...

Embodiment 3

[0054] Example 3: Selection of dwarfing agent combination

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

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

[0057] Test 2: Spray treatment with 80 ppm of membranous amine solution;

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

[0059] Test 4: First spray with 150ppm paclobutrazol aqueous solution; 3 days after the first spray, 80ppm aqueous solution of mecone was used for the second spray; 3 days after the second spray, 60ppm The third spray of the solution of Uniconazole;

[0060] Control: clean water treatment.

[0061] Table 6: The dwarfing effect starts on March 5th (with the newly increased height of the leaves)

[0062]

[0063] It can be seen from Table 6 that using combined dwarfing agents for spray treatment can significantly improve the dwarfing effect.

Abstract

The invention discloses an aquatic canna dwarfing method, and belongs to the technical field of agriculture. The method comprises the following steps: 1) selecting aquatic canna seeds for potting; 2)when the aquatic canna potted plants grow out of 4 and 5 buds of 2-3cm, and carrying out root leaching or spraying treatment by the paclobutrazol aqueous solution, the mepiquat chloride aqueous solution and the uniconazole aqueous solution in sequence, cultivating, and obtaining dwarfed aquatic canna. Through the successive treatment on the aquatic canna by the paclobutrazol aqueous solution, themepiquat chloride aqueous solution and the uniconazole aqueous solution, the dwarfing effect can be realized; by combining with a special nutrient solution, the height of the plants can be remarkablyreduced, the plants are compact and strong, and the height of the treated plants is 1 / 2-1 / 3 shorter than that of the compared plants, the leaf color is deepened, the leaf width is increased by 20-40%,and the thickness is increased by 10-20%.

Description

Technical field [0001] The invention belongs to the technical field of agriculture, and specifically relates to a dwarfing method of aquatic canna. Background technique [0002] Plant dwarfing technology has been widely used in terrestrial plants, especially dwarfing plants as the main species for landscape cultivation, such as tree bonsai, stump bonsai, flowers (such as celosia) and so on. Rice, the staple food of most people in my country, is a very typical example of successful dwarfing. In the 1950s and 1960s, the rice stalks were very long and tall. Almost 50 out of 100 rice stalks would fall down every year. The better the ears, the heavier the ears would fall. After the stalks fall, the millet will germinate in the ground. , Seriously affect the output and quality of millet. The height of rice stalks today is almost only 50-60% of the old ones, and almost no lodging occurs. Although rice is not an aquatic plant, it grows in water for a lifetime and is very similar to aq...
