The weight of 1000 seeds is 5.9g and the life span is 3 years. In this issue, the editor shares with you the picture of zinnia and the way it is sown.

Hundred-day grass-growth habits like warm, not cold-resistant, afraid of heat, strong sex, drought tolerance, pimple tolerance, avoid continuous cropping. The root is deep and the stem is hard and not easy to lodge. It is suitable to grow in fertile and deep soil. The suitable temperature during the growing period is 15 ~ 30 °C, which is suitable for cultivation in the north. Dwarf species in hot areas, should be planted in light shade, there are about 20 species of the same genus, such as small hundred grass, fine leaf hundred grass and so on. It likes a warm climate, is not cold-resistant, likes sunshine, is resistant to drought and barren, and the suitable temperature for growth is 15 Mel 30 degrees Celsius, which is suitable for planting in the north. Hundred-day grass-the whole herb with medicinal value can be used as medicine, which has the effect of clearing heat, promoting dampness and detoxifying. Can also treat damp-heat dysentery; mammary abscess; furuncle. Internal administration: fried soup, 15-30g. External use: knowledge trial, fresh products tamping.

Zinnia-seed sowing 1. In the process of sowing, zinnia requires a well-drained, loose and fertile soil environment. Usually the germination temperature is 21 Mel 22 degrees, which needs to be covered with soil when germinating, and 2 Mel can germinate in 5 days. In the process of growth, the daily temperature should be kept at 18 degrees and the night temperature should reach 21 degrees. The time from sowing to flowering is generally 10 weeks. It is also worth noting that continuous cropping of 100-day grass should be rotated at the right time. 2. Because zinnia is easy to grow in the later stage of growth, growers usually take measures to control it: first, to properly reduce the temperature and increase ventilation; second, to ensure adequate nutritional area and increase plant spacing; third, to pick out the heart in time to promote axillary bud growth. If you want to make the plant low and blossom, you often spray dwarfing agent when the axillary buds grow to about 3 cm after coring. Coring treatment should also be carried out in order to limit its growth height. 3. The hundred-day grass grows strongly and likes a warm, dry and sunny environment. The suitable temperature for growth is 20-25 ℃, and it is not resistant to heat. When the temperature is higher than 35 ℃, the growth weakens obviously, the flowering is rare, and the flowers are smaller. In short days, the ligulate flowers became smaller and the tubular flowers increased. It is necessary to choose fertile soil with deep soil layer and good drainage to grow best. 4. Zinnia is mainly propagated by seed and can also be propagated by cuttage. Seed propagation should be sowed in spring, usually in the middle and last ten days of April, and its seeds are light-resistant, so they should be covered with soil, watered and moisturized after sowing. The germination rate is generally about 60%. Cut a section of shoots 10 to 15 centimeters long, remove the lower leaves, leave the upper two leaves, insert them into the soil, often spray water, properly shade, and wait about 2 weeks before they can take root and sprout. Conclusion: the flower language of hundred-day grass is to miss a friend far away, Tian Chang Di Jiu (Eternal Dumpling). The hundred-day grass has a long flowering period, and the flowers bloom one after another and bloom beautifully for a long time, which is also a symbol of friendship Tian Chang Di Jiu (Eternal Dumpling). The color of the hundred-day grass flower is very rich, for pot appreciation, the ornamental value is very high, and one flower is higher than the other, which will inspire people's ambition.

How to plant zinnia seed sowing method of zinnia seed

Zinzinnia generally refers to zinnia, an annual herb of the genus Compositae, native to Mexico, with single, double, curly leaves, wrinkled leaves and horticultural varieties of different colors. It is widely cultivated in various parts of our country, and sometimes it becomes wild. It can be used in flower beds, flower borders, flower belts, and often used in potted plants according to height. Let's take a look at how to plant seeds.

Seed selection

The seed life of zinnia is 3 years, and the germination rate is about 60%. Try to choose the full seeds of the previous year to improve the seed germination rate. When the petals of the outer wheel begin to dry up and the petals of the middle wheel begin to fade, cut off the flower head, dry it and store it.

Disinfection treatment

Before sowing, the soil and seeds should be strictly disinfected to prevent diseases and insect pests during the growing period. the seeds were soaked in 1% potassium permanganate solution for 30 minutes. The matrix is made of 2 parts of rotten leaf soil, 1 part of river sand, 2 parts of peat and 2 parts of perlite, which can be disinfected with 0.05% potassium permanganate or 1000 times formaldehyde, and the soil can be fumigated at high temperature to kill germs, pests and grass seeds.

Sowing time

The sowing time of hundred-day grass depends on the required flowering time, generally sowing in the greenhouse 2-3 months in advance, direct seeding in the open field should be after the severe cold in early spring, otherwise the seedlings are underdeveloped. If the flower bed is used in autumn, it is suitable to sow in summer, spring sowing in March to April, transplanting in 4 to 5 leaves, planting in early June, and flowering from July to Frosts Descent.

Sowing method

Zinnia seeds can be sowed on demand or withdrawn, because they are photophobic flower seeds, they must be covered with vermiculite after sowing, and they can germinate in 3 to 5 days at 21: 23 ℃. There is no need for light during the germination period. After germination, the seedling bed should keep 50% of the water content, not too wet, so as to avoid rotting roots or sudden falling disease.

Seedling management

After the seedlings of zinnia grow out of a true leaf, the seedlings are transplanted once, the root system of zinnia is undeveloped, and the lateral roots are less. Generally, when transplanting 2 true leaves, it should be planted in a pot, and the transplanting substrate should be loose, fertile and well drained. It can be prepared with 3 parts of pond mud, 1 part of rotten leaf soil and 1 part of mature heap manure, and the planting depth is 0.5 cm under cotyledons. After planting, the soil is lightly pressed and watered.
