Qingyun is a cactus plant, and likes dry soil environment. Therefore, attention should be paid to controlling watering in winter and spring with low temperature, otherwise it will easily lead to root rot. After entering the summer, the plants can be properly topdressed and managed in a place where they can receive 3-4 hours of direct sunlight every day, and the wintering temperature is not lower than 5℃.

Breeding method of soaring: conservation method

Key points of cultivation: fertile loam or humus should be selected as the cultivation substrate, with good drainage. Light 50? 60% shading is better to avoid direct light. Indoor cultivation should be placed in a well-lit place. Insufficient light will make the leaves fade, and the leaves are slender and wavy. Fertilization can use organic fertilizer, such as rotten peanut bran or human feces as fertilizer, and at the same time cooperate with 3? Four times that of ternary foliar fertilizer. Sex likes high temperature and high humidity, and the growth temperature is 20? Winter 35℃ and 10℃ should pay attention to cold protection measures to prevent freezing damage from drying up the leaves. Pay attention to ventilation and keep the relative humidity of air above 80%.

Changing pots and plastic pipes: Every spring is the best time to change pots. When the plant shape is large enough, it is advisable to change the big pot to make the roots have more room for growth. Dracaena plants are resistant to pruning. As long as the top or upper branches are cut off, the buds below the incision will germinate and grow into new branches, which can grow 1 at the same time. Five buds enrich the crown width, make the plant shape more symmetrical and increase the beauty of the plant shape. Many growers often cut off the top when the plants grow to 1 m high. After six months to a year, the price of plants can be increased by 3? This is a typical flower deep processing process.

Propagation: tissue culture and propagation are the main methods, and cutting propagation can also be used. The seedlings produced by tissue culture and propagation are neat and stable.

Pest control: Common phenomena include scorching tip and scorching edge, which are diseases caused by too dry air, too irregular watering and fertilization or too low temperature after drought. Only by strengthening daily management can we overcome them.

Feeding method of soaring: feeding precautions

The demand for water is not great, and it is generally advisable to water it when it is dry and wet alternately; The fertilizer can be 20-20-20 water-soluble fertilizer of Huaduoduo, and the growth of yemen iron in Jin Xin is slow.

The demand for fertilizer is relatively small. Because the root system is underdeveloped 3-4 months before planting, it is generally enough to pour 20-20-20 water-soluble fertilizer twice a month. If the amount of fertilizer and water is large, it will grow in yemen iron, Jin Xin. When the amount of fertilizer is large, the leaves that have just been pumped will shrink and not spread; In the last 4-5 months, the plants grow vigorously and the roots are developed. Generally, watering water once every half month is 20-20-20 times more than water-soluble fertilizer 1000 times.

The optimum growth temperature is 20-30℃. When the temperature is high in summer, you need proper shade. In winter, the room temperature is not lower than 5℃, and the dormancy temperature is 65438 03℃. If the temperature is too low, chloasma will appear on the tips and edges of leaves. In winter, heating equipment is needed for maintenance. If heating facilities are not used, double insulation facilities can be used. When the temperature drops to 22-24℃ in the afternoon in winter, the shed should be closed in time (generally, in the north of the shed in summer, if it is planted in a simple shed, the shed is covered with 1 layer shading net with a density of 75%, and a layer of 50% shading net can be added in the shed to cool down. Shading and ventilation can be strengthened in summer. At the same time, long-distance multi-span greenhouses should not be used, but independent single ceiling should be used.

Breeding method of soaring: fertilization method

Fertilize soil or land

1, apply fertilizer a few times, but not too much.

2. Fertilization can use organic fertilizer or ternary foliar fertilizer, 3-4 times a month.

3. Stop fertilizing when the temperature is low in winter.

In addition, it should be noted that fertilizers should not be biased. Today, I will share with you a relatively easy-to-use fertilizer-Yongkang special fertilizer for flowers, which can provide nutrients needed for Qingyun's growth and development, prevent diseases and stress, improve photosynthetic efficiency and improve ornamental effect, and is more suitable for Qingyun's application.
