Culture methods and matters needing attention of silk reeling flowers

What problems should be paid attention to in silk reeling flower culture? next, let's introduce it to you.

Silk reeling flowers, also known as Rosa roxburghii, wooden pear, Rosa roxburghii, etc., are shrub plants of the genus Rosaceae, with beautiful flowers and a dense circle of golden anthers in pink petals, which are very chic, yellow thorns are quite wild and have high ornamental value. suitable for slope and roadside planting and greening, but also used as medicine Gracilaria material.

Propagation methods of silk reeling flowers

1. Sowing: silk reeling flowers are usually collected in September, can be sowed in autumn or stored in sand until the following spring, and generally germinate 20-25 days after sowing. Seeds can be used to raise seedlings, but it is generally not recommended to use seeds for cultivation because it is difficult to survive. In production, young twigs of the same year are often used to raise seedlings, which is easy to survive. Valuable varieties are more difficult to insert.

2. Cuttings: silk reeling cuttings can be inserted in early spring or plum rain seasons. it is easy to survive with young twigs in the same year. After planting, we should pay attention to keep the substrate moist, but do not make it too wet, otherwise it will cause rot. At the same time, we should also pay attention to the humidity of the air, can be covered with plastic film to maintain humidity, but should pay attention to ventilation in a certain period of time.

Culture methods of silk reeling flowers

1. Lighting: silk reeling flowers like a warm and sunny environment, which can be cold and shady, so when reeling flowers are cultured, they should be given sufficient light and maintain a suitable growth temperature.

2. Watering: silk reeling flowers need to ensure adequate moisture during maintenance, but pay attention to adequate moisture during summer drought. In the flowering period, it is also necessary to ensure adequate water supply in order to bloom luxuriantly and brightly. In the rainy season, we should pay attention to do a good job of drainage, there is no stagnant water, so as not to make the roots rot.

3. Fertilization: in order to make silk reeling flowers grow healthily, it is necessary to ensure sufficient fertilizer and water. During the comfortable growth period, you need to be diligent in fertilization, which can be applied once a month. You can apply some thin fertilizer when the temperature is higher and drier, reduce fertilization in winter, and apply quick-acting fertilizer once or twice after flowering.

4. Pruning: pruning is essential, whether it is too long branches, too dense branches, dead branches, diseased branches or residual flowers, rainy buds are very necessary, pruning can be reeling flowers beautiful, and conducive to ventilation and light, so that plant growth and development is better, reduce the occurrence of some diseases and insect pests, and reduce the consumption of nutrients, better flowering.

Disease and pest control of silk reeling flowers

1. Powdery mildew can occur in leaves, petioles, shoots and buds. At the initial stage of the disease, 20% triadimefon EC 1000 times or 20% triadimefon sulfur suspension 1000 times and carbendazim wettable powder 1000 times were sprayed. If there is resistance to the above fungicides, 12.5% nitrilazole EC or 3000 times Teflin wettable powder can be sprayed instead. Spray Baume 2 / 3 stone sulfur mixture or 45% crystal stone sulfur mixture 40 / 50 times before sprouting in early spring to kill overwintering bacteria.

2. Black spot: black spot mainly affects the leaves, petioles and tender shoots of silk reeling flowers. at the beginning of the disease, the leaves appear purple-brown to brown spots, and when enlarged, they are mostly round or amorphous dark-brown spots. When black spot occurs in silk reeling flowers, carbendazim, methyl thiophanate, daconine and other drugs can be sprayed.

3. Anthrax: anthrax occurs sporadically, which can be treated simultaneously in the prevention and treatment of black spot and leaf spot. In late autumn and early winter, the garden was cleared in time to collect sick fallen leaves and burn them. Strengthen maintenance, proper pruning, thinning too dense branches, so as to make good ventilation and light transmission. If necessary, spray 20% long Ke suspension 500x solution or 78% Cobo WP 600x solution, 75% Daconine WP 600x solution, 50% Shi Bao Gong or Shi Bai Ke WP 1000 times, 25% Chitalin WP 500x.

4. Beetle: the beetle mainly harms the roots, leaves, buds and other parts, seriously affecting the yield and quality of flowers. Light trap, willow trap, oscillation trap and so on. When the damage is serious, 2.5% deltamethrin 2000-3000 times or 50% phoxim 1000-1500 times can be sprayed. The effect is good, but it must not be sprayed at flowering stage.

5. Leaf blight disease: it is a common disease of silk reeling flowers, which may occur in leaves and new branches. Serious illness will cause a large area of leaves to fall off, so that flowers lose their ornamental value, and even die. If you find this disease, to deal with it in time, you can use 800 times liquid triadimefon foliar spray, once a week, continuous 3-4, the disease can be basically cured.
