Problems solved by technology

[0004] Because Pyrethrum alba is suitable for ground cultivation, and when it is cultivated in containers, it will affect the plant type of Pyrethrum, so there is no literature on the potted planting technology of Pyrethrum, and the research on the application of Pyrethrum as an insect-resistant and insect-repelling ornamental flower is still blank at home and abroad.

Embodiment 1

[0021] Embodiment 1: Butyrazyl hydrazine spray experiment

[0022] 1 Experimental materials

[0023] 1.1 Plant material: The seeds of Pyrethrum diffusa were collected from the Ornamental Plant Germplasm Resource Garden of the Institute of Forestry and Fruit Trees, Wuhan Academy of Agricultural Sciences. Soak the seeds in clean water at room temperature for 5 hours, screen the imbibition seeds that sink to the bottom of the water, and dry them in a ventilated and cool place for later use; sow the screened plump seeds in the hole trays, and 5-8 seeds can be implanted in each hole. The depth of seed implantation is about 1cm; the planting substrate is a mixture of peat soil and perlite at a ratio of 1:1; sufficient water is poured after sowing; during seedling cultivation, the water content of the plug culture medium is kept at 70%-80%, and the air humidity is 60%- 80%, the temperature is 20°C-25°C, the light time is 16h / day; the seeds can germinate in about 1-2 weeks; after the...

Embodiment 2

[0033] Embodiment 2: Chlormequat spraying experiment

[0034] The same plant materials, experimental conditions and methods as in Example 1, the difference lies in the use of different reagents and different results. The reagent is: chlormequat, produced by powder (≥98%) of Shanghai Yuanye Biotechnology Co., Ltd.; chlormequat is dissolved in deionized water, and the concentration is respectively prepared into 100mg / L, 200mg / L, 300mg / L, 400mg / L, 500mg / L aqueous solution; ready to use.

[0035] Result analysis:

[0036] As shown in table 2.

[0037] Table 2 Effects of spraying different concentrations of chlormequat on plant height, plant width and flower volume

[0038]

[0039] Combine Table 2 with figure 2It can be seen that compared with the control, after spraying different concentrations of chlormequat on the leaves of potted pyrethrum, the plant height, plant width, growth vigor and flower volume all decreased significantly. 100mg / L of chlormequat had a significa...

Embodiment 3

[0040] Embodiment 3: Uniconazole spraying experiment

[0041] The same plant materials, experimental conditions and methods as in Example 1, the difference lies in the use of different reagents and different results. The reagent is: uniconazole, produced by powder (≥95%) of Shanghai Yuanye Biotechnology Co., Ltd.; uniconazole is insoluble in water and needs to be dissolved in a small amount of methanol first to make an emulsified solution, and then deionized water, respectively Prepared into solutions with concentrations of 100mg / L, 200mg / L, 300mg / L, 400mg / L, and 500mg / L; ready-to-use.

[0042] Result analysis:

[0043] as shown in Table 3.

[0044] Table 3 Effects of spraying different concentrations of uniconazole on plant height, plant width and flower volume

[0045]

[0046] Analysis table 3, image 3 According to the data in the study, after spraying different concentrations of uniconazole on Pyrethrum chrysanthemum, the growth of plant height and width were signi...

Abstract

The invention provides a Tanacetum cinerariifolium dwarf potting method. The Tanacetum cinerariifolium dwarf potting method includes the following steps: selecting healthy and full Tanacetum cinerariifolium seeds, and cultivating seedlings by using hole plates; performing potting while the seedlings have 1-2 pairs of real leaves, spraying leaves of the potted seedlings having 2 pairs of real leaves with a 80-230 mg / L daminozide solution, performing spraying once every 6-8 days, and totally performing spraying for 3-5 times. The Tanacetum cinerariifolium plants processed by the method is lowered to about 30% of contrast plants, and adverse impact on leaf development, plant width, and flower number of the Tanacetum cinerariifolium plants is less; the plant width of the Tanacetum cinerariifolium plants is above 75% of the contrast plants, the flower number of the Tanacetum cinerariifolium plants is above 80% of the contrast plants; the processed Tanacetum cinerariifolium plants are short,strong and compact, are sufficient in flowers, and are suitable for potting; and the diversity of natural plant-derived insect-resistant ornamental plants is enriched.

Description

technical field [0001] The invention belongs to the technical field of potted ornamental plant cultivation, and in particular relates to a dwarf potted method of pyrethrum albicans. Background technique [0002] White-flowered pyrethrum (Tanacetum cinerariifolium) is a perennial herb of Compositae, Artemisia genus, Pyrethrum species, introduced from Yugoslavia in the 19th century, stems, leaves, flowers and fruits are raw materials for making botanical insecticidal pesticides. Poisonous to fish, amphibians and reptiles, less toxic to birds and mammals, no residue, no pollution. Pyrethrum alba is currently the only intensively cultivated insecticidal plant in the world. The natural pyrethrin extracted from pyrethrum can quickly kill mosquitoes, flies, aphids and other pests without pollution, pollution, and residues. It is an ideal raw material for the manufacture of green plant pesticides, which is in short supply in the international market. [0003] The plant height of P...
