Seed price and planting method of chrysanthemum

Chrysanthemum is a valuable ornamental flower cultivated by long-term artificial selection, also known as Shouke, Jinying, Huang Hua and so on. It is a perennial perennial herb of the genus Compositae, with exuberant growth and strong germination. A chrysanthemum can produce thousands of buds after picking the heart many times. It is of high ornamental value and can be used as medicine to treat diseases. Let's take a look at the price and planting method of chrysanthemum seeds.

How much is the chrysanthemum seed per jin?

The price of chrysanthemum seeds is about 40-50 yuan per jin, which varies greatly due to the quality and variety of seeds. There are two kinds of propagation of chrysanthemum: vegetative propagation and seed propagation. Vegetative propagation includes stem cutting, ramification, grafting, striping and tissue culture, etc., usually mainly by cutting propagation, including bud cutting, tender branch cutting, leaf bud cutting and so on. The seeds germinate slowly above 10 degrees Celsius, the optimum temperature is 25 ℃, and the seeds can blossom in the same year under normal sowing conditions.

Sowing method of Chrysanthemum

1. Soil selection: when sowing chrysanthemum, loose soil rich in organic matter should be selected, and a certain amount of mature organic fertilizer should be applied as base fertilizer before sowing.

2. Sowing method: when sowing chrysanthemums, mix the seeds and a certain amount of sand evenly, and spread them evenly on the seedling bed, then cover the soil for about one centimeter.

3. Post-sowing management: chrysanthemum should maintain soil moisture after sowing, the temperature should be controlled at about 18 ℃ to germinate, and the temperature, air humidity and sunshine should be sufficient.

4. timely transplanting: when the chrysanthemum seedlings grow 4 to 5 true leaves, the chrysanthemum seedlings can be transplanted into the nutrition bowl and removed from the heart, and there is no need to apply topdressing during the seedling growth period, so as not to cause excessive growth of branches and leaves and affect flowering.

Planting methods of Chrysanthemum

1. Soil: chrysanthemum has wide adaptability to soil acidity and alkalinity, and can grow in slightly acidic to slightly alkaline soil. the pH value is between 5.5 and 7.0. 6 parts of rotten leaf soil, 3 parts of sand and 1 part of cake fertilizer residue can be used to prepare mixed soil.

2. Temperature: the suitable temperature for chrysanthemum growth is about 21 degrees Celsius, which is more resistant to cold and can survive the winter safely under the condition of about 5 degrees Celsius, but it is not resistant to heat. When the temperature is above 32 degrees Celsius, it will grow slowly.

3. Illumination: chrysanthemum is a typical short-day flower, which forms flower bud and blossoms only when the sunshine is short every day. It needs 14.5 hours of sunshine per day in vegetative growth period and 12 hours per day in flower bud differentiation period.

4. Moisture: chrysanthemums have a large demand for water, but they are afraid of stagnant water, especially during the period of vegetative growth, the growth rate is fast, water demand is large, and it is easy to lack water. Water should be watered frequently, but be careful not to accumulate water.

5. Fertilization: when applying fertilizer to chrysanthemum, the fertilizer must be sprinkled first, and then watered thoroughly, so that the fertilizer can fully seep into the root system of chrysanthemum with water, so that the fertilizer can be absorbed.

6. Coring: when the chrysanthemum plant grows to more than 10 centimeters high, it can begin to pick the heart, leaving only 4 or 5 leaves at the base of the plant, all the upper leaves are removed, and the branches and buds that grow later should also be removed in time.

7. Diseases and insect pests: the main diseases of chrysanthemum are rust, black spot and gray mold, which do great harm to the growth of chrysanthemum, so it must be properly controlled in the process of chrysanthemum cultivation.

① rust: it harms leaves and stems, especially leaves. It can be sprayed with 65% Daimen zinc wettable powder.

② black spot: the main damage to leaves, can be sprayed with the same amount of Bordeaux solution.

③ Botrytis cinerea: harmful to flowers, leaves, stems, etc., spraying with 65% Daimen zinc wettable powder at the initial stage of the disease.
