1. Promoting the root of the cuttings

Naphthalene acetic acid sodium and IBA. After the chrysanthemum flower buds formed in September and October, cut off the tender branches with buds about 10 centimetres long. The bottom of the branch dipped in 500 mg per liter of sodium naphthalene and 250 mg per liter of IBA and mixed it into a liquid and then planted the branches, which can significantly promote rooting. In addition, the branches was briefly dipped in the IBA solution of 1000-1500 milligrams per liter for 5 seconds, then combined with nutrient fog spraying, which was especially effective in promoting root growth and root growth. Japanese embroidered chrysanthemum flowers bloom in mid-june, then take its branches or take the hard branches of the middle of July as the scion of the ear, with 50-100 mg per liter of IBA immersion treatment, which can significantly promote its root and improve the survival rate.

Dinyl hydrazine. Before the cut, immerse the bottom of the branches in 5, 000 milligrams of butyl hydrazide for 15 to 20 seconds, which can also accelerate the root.

2. Promoting chrysanthemum growth

Gibberellin. For dwarf chrysanthemum varieties, the growth of the flowering branches can be increased by spraying 2 times of the gibberellin with 500 to 1000 mg per liter during the growth period. After chrysanthemum planted 1-3 days and 3 weeks, each spurt 1.5-6 mg each litre of gibberelline fluid, which also can increase the stem length of chrysanthemum.

The African chrysanthemum uses 50mg per liter of gibberellin for leaf spraying, which can improve the length of chrysanthemum branches and improve its quality and yield.

After the chamomile sprouts in the greenhouse,it is sprayed with 100 mg of gibberellin in their 2 growth critical periods, which can promote plant growth and flowering, and improve flowering quality.


3. Dwarfing the plant height

Multi-effect azole. Potted plants are usually short for beauty. In the early stage of the monomile growth, 15% of the Multi-effect azole powder was diluted 1000 times and sprayed on the chrysanthemum. It is sprayed once every 10 to 15 days depending on the growth condition, so that the shape of the plant can be kept neat. In the future, the plant will be sprayed every 15 days or so, until the bud is clear. When marigold is inserted into a post, spray it with the above dazole solution, and spray it once every 10 days after planting, until the bud is clear. In the process of making miniature potted marigold, they can be dwarfed before they are inserted. In general, use 1000mg of the polyzonazole solution to the leaf surface 10 to 15 days before the insertion. During the growth period, the chrysanthemum grows stable and then spray the chrysanthemum plant blade to the heart of chrysanthemum with 1000 mg per liter of polyoxazole, spray one or two times every 15 to 20 days.

During the time of the potted plant, with 50 to 100 milligrams of every liter of it, it will dwarf the plants and enhance the viewing.

The use of butyl hydrazide inhibits the growth of mums and should be sprayed every 10 days from the tenth day after planting. The spray concentration is 1.5g 40% of butyl hydrazine. Shake butyl hydrazine with hot water (about 50 degrees Celsius) 10 kg, and shake well, then cool and spray directly on the chrysanthemum. After this treatment, it can shorten the stem rod of chrysanthemum, make the stem short and strong, firm. In addition, spraying the chrysanthemum flowers with 500 mg of butyl hydrazide liquid can prevent the flower stem from growing to high quality cut flowers.

China aster can also be controlled effectively by the 0.3 per cent butyl hydrazine solution.

The height of Persian, marigold was significantly reduced and the ornamental value improved after the use of the leaf surface spraying by chrysanthemum.

4. Tip and trim

Aliphatic alcohols. Using 0.05mol/l of fatty alcohols to spray the plants of the bamboo, chrysanthemum, hydrangea and geranium, the plants were able to produce multiple lateral branches

5. Adjust flowering

5.1. Promote flowering.

Gibberellin. The dosage of 10ug per flower will be used to add water to the protoplast of gibberellin and not sensitive to the light cycle, which will require cold treatment of the chrysanthemum, so that it can be induced to bloom. In the potted flower buds for 4 to 5 mm in diameter, spraying concentration for 500-1000 mg per litre of ga3 can obviously accelerate the buds open. when the color is clear, spraying concentration of 100 mg per litre of ga3 can make the whole plant flowering period significantly ahead of time

5.2 Delay flowering

2.4-D, Naphthalene acetic acid sodium. The differentiation of flower bud can be delayed by spraying chrysanthemum with 2.4-D and sodium naphthyl acetate. Using 5 mg per liter of 2.4-D liquid can delay the chrysanthemum by 30 days.

Naphthalene+naphthalene. With 50 mg of sodium naphthalene plus 50 mg per liter of gibberellin mixed treatment can enhance the effect of inhibiting the bud.

Butyl hydrazine. The flowering period of chrysanthemum can be extended by the spraying of 2, 500 mg of butyl hydrazide in 3 weeks after the onset of short sunshine.

Sumagic. In the early stage of chrysanthemum flower bud differentiation, spraying the mums 2 times to 3 times with 50 mg per liter of dazole or 5 mg per litre of enzole can Control length and prolong the viewing time.

6. Chemical preservation

6.1 Treatment before the chrysanthemum is picked

Butyl hydrazine. In the 3 to 8 weeks after the chrysanthemum grows, the spraying 2.5% of butyryl hydrazine can prolong the life of the cut flower for 5 days.

6.2 Treatment after the chrysanthemum is picked

The chrysanthemum is also known as the autumn chrysanthemum, is the subshrub of the genus chamomile. Chrysanthemum flower type and color is rich and colorful, and individual varieties also have aroma. It is the traditional Chinese flower and the popular cut flowers. Flowers picked during the flower buds can be used for 20-50 per litre of sucrose plus 25 mg per liter of silver nitrate plus 75 milligrams of citric acid per liter of citric acid per liter to urge the bud to bloom. The chrysanthemum itself has a strong resistance to blight. After picking, it can improve the quality of chrysanthemum and prolong the life of the flower if take some fresh measures. For example, before inserting a chrysanthemum as a landscape into a bottle, using 50 grams of sugar per liter of sugar plus 0.3mol/l of silver sulphate and 75 citricmg/l citric acid deal with the flowers. It also is feasible to insert the chrysanthemum into 1mg/l 6-ba liquid for 24 hours. You can also directly insert the chrysanthemum into 20 to 50g/l sucrose plus 30mg/l silver nitrate plus 75mg/l citric acid or 1-5mg/l 6-ba fresh liquid.

African chrysanthemum. The African chrysanthemum is also known as Gerbera jamesonii and Erigeron breviscapus and is a herbaceous plant. The main problem with flower preservation in Africa is that it is easy to break and decompose.Thus, the chrysanthemum can be treated with 1000 mg of silver nitrate for 10 minutes before being inserted into the bottle. In addition, the African chrysanthemum also can be put in the 70g/l sucrose plus 200mg/l citric acid plus 25mg/l silver nitrate in the purpose of preparation. African chrysanthemum flower could have a longer life if they are inserted into a bottle. But if you insert it into 20mg/l of silver nitrate plus 150mg/l of citric acid and 50mg/l of sodium phosphate, it can further prolong its life.
