What are the planting methods of perennial herbaceous plant chrysanthemum seeds? When do you plant it? What are the planting prospects?

Chrysanthemum is a perennial root herb of Compositae and Chrysanthemum in plant taxonomy. Chrysanthemum is a valuable ornamental flower cultivated by long-term artificial selection. What are the seed planting methods of chrysanthemum? When do you plant it? What are the planting prospects? Chrysanthemum is the third of the top ten famous flowers in China, and one of the four gentlemen (plum orchid bamboo chrysanthemum).

I. planting methods of chrysanthemum seeds

1. Potted soil: fertile sandy soil should be selected for chrysanthemum cultivation, with a small basin first and then a large basin. After changing the basin for 2 or 3 times, the basin can be fixed in July. 6 parts of rotten leaf soil, 3 parts of sand and 1 part of cake fertilizer residue can be used to prepare mixed soil. After watering thoroughly, put it in a cool place, wait for the plant to grow normally and move to the sunny place.

2. Watering: chrysanthemum seedlings are young in spring, watering should be less. When the chrysanthemum seedlings grow up in summer, they can be watered once in the morning and again in the evening, and spray water on the branches and leaves of chrysanthemum and the surrounding ground with a sprinkler to increase the humidity of the environment. Before the Beginning of Autumn, it is necessary to properly control water and fertilizer to prevent the plant from growing too high. The Beginning of Autumn should increase the amount of water and begin to apply fertilizer before flowering, and the fertilizer and water will gradually thicken. In winter, flower branches basically stop growing, plant water consumption is significantly reduced, evaporation is also small, watering must be strictly controlled.

3. Fertilization: when planting chrysanthemum plants, sufficient base fertilizer should be applied in the basin. In the future, nitrogen fertilizer can be applied every 10 days. The Beginning of Autumn can apply slightly thicker fertilizer and water once a week from chrysanthemum budding to budding, and then suspend fertilization after applying thick fertilizer and water once more. If the chrysanthemum can be given calcium superphosphate or 0.1% potassium dihydrogen phosphate solution at this time, the flowers can bloom more brightly.

4. Heart picking: when the chrysanthemum plant grows to more than 10 centimeters high, it begins to pick the heart. Only 4-5 leaves were left at the base of the plant during coring, and all the upper leaves were removed. When 5 or 6 new leaves are grown, the heart is removed so that the plant retains 4 or 7 main branches, and the branches and buds that grow later should be removed in time. Coring can make the plant branching and effectively control the plant height and plant type. When picking the heart for the last time, the chrysanthemum plant should be stereotyped and pruned, too many branches, too strong and too weak branches should be removed, and 3-5 branches should be retained.

5. Bud thinning: when the chrysanthemum buds appear in September, the buds at the lower end of the plant should be removed, leaving only one bud at the top of each branch.

When will it be planted?

There are two methods of vegetative propagation and seed propagation of chrysanthemum. Vegetative propagation includes stem cutting, ramet, grafting, striping and tissue culture, which is usually based on cuttage propagation. If you choose to sow chrysanthemum, it is best to do it in spring, summer or late autumn, and it is suitable to split roots and transplant chrysanthemum before May 15, and before June 16.

Third, what is the prospect of chrysanthemum planting

Take white chrysanthemum as an example, the cost is about 2000 yuan / mu: it needs 2500 chrysanthemum seedlings / mu, and the current market price of chrysanthemum seedlings varies from 0.12 yuan to 0.45 yuan per plant. During the growth process, it takes 100 yuan / mu to apply fertilizer such as farm manure, 150 yuan / mu for irrigation water, 30 yuan / mu for plastic film mulching, 0.8-1 yuan per jin of fresh flowers and 100,200 yuan / mu for land rent.

The income is about 7000 yuan / mu: 2500-2800 jin of flowers per mu, the current purchase price of flowers (fetal chrysanthemum) 2.8yuan / jin, golden chrysanthemum (high-end varieties) 3.2yuan / jin, the highest income can reach nearly 9000 yuan (golden chrysanthemum).

Therefore, under scientific planting, according to the current market price, the profit should be 5000 yuan / mu.

Additional income: in the second year of planting, seedlings can be bred by cutting and other methods, and 15-20 mu of new fields can be planted with old seedlings per mu, that is, 2500 old seedlings per mu can produce up to 50, 000 new seedlings. at present, the market price of seedlings is calculated at 0.20 yuan per plant. you can get an income of 10,000 yuan per mu by selling seedlings to the outside world.
