The planting method and Propagation of Flowers-- Man Tianxing

The stars are like stars, hazy and charming, as if covered with snow, clear and lovely, suitable for flower beds, roadside and flower hedge planting, but also very suitable for potted ornamental and bonsai production. So how are the stars raised? Is there any good method in breeding? What matters do you need to pay attention to when raising all-sky stars? Please read on with me with questions.

The breeding method of all over the sky (basic knowledge):

The best breeding time: sowing time: from autumn to early spring.

The best growth soil: Mantianxing should grow in the sunny environment and loose, fertile, well-drained slightly alkaline sandy loam, the soil is required to be loose, rich in organic matter, moderate water content, about PH7.

Growth humidity requirements: if the star is a growing flower, it is best to keep it in a sunny and well-ventilated place, and keep the soil moist at all times.

The optimum growth temperature is 10-25 ℃.

The best growth light: the sky stars like warm, humid and sunny environment, more shade-resistant, cold-resistant, avoid high temperature and humidity.

Matters needing attention for culturing all over the sky:

Fertilizing: during the starry growing season, we can fertilize phosphate-rich tomatoes diluted with water every two weeks or so.

Watering essentials:

(1) if Mantianxing is in the period of flower and seedling, then it needs more water.

(2) after picking the heart, it is necessary to continue to maintain sufficient moisture and fertilizer for him, especially in the hot and humid summer season, which is often the most important factor that determines the success of his cultivation.

Pruning essentials:

The main results are as follows: (1) pay attention to pruning the whole plant in autumn to maintain good plant shape.

(2) the growth of the stars is very strong, and the fallen leaves can be cut off at will, and new branches and leaves will grow soon. The more you cut off, the fuller the new leaves will grow.

Pot soil replacement: when Mantianxing changes the basin every spring, add fresh and fertile soil, keep the basin soil moist during the growing period, and apply fertilizer once every 2 weeks to promote multiple branches and leaves and blossom.

Main points of reproduction:

(1) sowing: the full sky star sowing time. From autumn to early spring. The suitable temperature for growth is 10-25 degrees Celsius. Flowering period: from May to July. Seedling raising: choose loose soil to make bed, sow in September, cover fine soil slightly, germinate in about 10 days, and move to cold bed before winter. Cultivation: in the following spring, the seedlings were transplanted into the open field with soil, and the seedlings were plucked once after they were planted and survived, promoting their multi-branching. When the height of the plant is more than 20 cm, the amount of irrigation is reduced appropriately, and a little drought can promote flowering. It blossoms in the middle and late May, and this species can also be directly broadcast in the open field before freezing in November or sown in early spring.

(2) Cuttage propagation: hardwood cuttings were carried out in spring, and the mature branches of last year were cut 10~15cm long and inserted into the sand bed. Generally, they took root in about 30 days. Softwood cuttings can be used in the rainy season, select the top softwood cuttings in the current year, and take root 2-3 weeks after cuttage. It should be noted that the control of temperature and humidity must be verified. Generally speaking, the relative humidity is kept above 95% and the temperature is controlled above 15 ℃.

Pest control:

(1) the harm of leaf spot disease can be sprayed with 65% Dysen zinc wettable powder 600 times.

(2) the pests are harmful to aphids and red spiders, which are sprayed with 1000 times of omethoate EC. Aphids can also be sprayed with essential oil dilution or neutral detergent.

(3) snails can be sprayed in the basin soil with Miaoling granules.

(4) the phenomenon of stagnant water in basin soil should be prevented from root rot disease, and the root should be irrigated with green cream copper EC or 800-fold solution of root rot.

The experience of breeding all over the sky:

1. Like warm, humid and sunny environment, more shade-resistant, cold-resistant, and grow best in well-drained, fertile and loose loam. The cultivated soil quality of slightly alkaline calcareous loam is better, and the drainage and sunshine are good. The height of the plant has been more than 20 cm, the amount of irrigation is reduced appropriately, and a little drought can promote flowering, especially poor drainage or long-term rain after flowering, and the roots are easy to rot. The sex likes to be warm, avoid high temperature and humidity, and the suitable temperature for childbearing is 10-25 ℃.

2. Tissue culture. Using stem tip culture, the propagation coefficient is high, the root growth condition is good, and the seedling quality is good. Cut flowers are produced by tissue culture seedlings with tall and straight branches, pure color and high quality.
