Winter resistant breeding methods and precautions: too long exposure to strong light will cause deat

Wintering is another name of Camellia, a traditional ornamental flower in China. It ranks eighth among the top ten famous flowers. It is also one of the world's precious flowers. It is the city flower of Chongqing, Qingdao, Jingdezhen and Wenzhou. So how does hardiness breed? What's the best way to breed? What should be paid attention to in winter breeding? Please read with me with questions!

The best breeding time: the suitable period of cuttage is in the middle and last ten days of June, and the sowing time is in October, the first and the middle of October.

The best growing soil: 1 / 2 ~ 1 / 3 pine needles which have been decomposed for one year should be added into the garden soil.

Growth humidity requirements: winter to change the appropriate humidity according to seasonal changes, plum rain weather, to reduce the amount of water spray.

The best growth temperature: it is resistant to winter, cold and heat, and the most suitable temperature is 18-25 ℃. Therefore, the environmental temperature should not be too high or too low, otherwise it will affect its growth.

The best growth light: it can endure winter and avoid strong light, so we must pay attention to the sunlight when planting. We need sufficient sunlight in spring and autumn, but in summer, we must avoid direct sunlight. As long as camellia is exposed to strong light for too long, it is easy to die. If there are conditions, it is best to transplant it under the sunlight shed.

Precautions for winter tolerance of bright winter resistant flowers: fertilizer application: Winter tolerant plants prefer fertilizer, so special attention should be paid to the use of fertilizers in the whole breeding process, such as adding phosphorus and potassium fertilizer to the upper pot, but the fertilization should not be too much. Generally, fertilization should be conducted three times in the last half year after flowering, and once in winter, so as to make the flowers more beautiful, It is better to put more phosphate in the fertilizer.

Watering points: Winter tolerant like humid environment, so we must pay special attention to it. It can't be too dry, too wet, or sometimes dry and wet. Generally, you can water more in spring, which is conducive to germination. In summer, it should be watered both in the morning and in the evening, and it is best to water the leaves. Never water plants when they are hot. Autumn is the same as spring, but you should pay attention to watering in winter, It's better to water the plants before and after, and not every time. It's better to do it every two or three days.

Pruning tips: Winter resistant pruning is very important. Generally, the branches that affect the tree shape and the diseased and weak branches are cut off, and the flower buds are arranged. Once the flower buds are too dense, they should be combed. After the flowers wither, they should be picked in time, which can reduce the consumption of nutrients.

Pot soil replacement: generally, the pot should be turned over once every two years to change a large pot, which is conducive to its growth. Special attention should be paid to the time of turning the basin. It is better to pay attention to the time when turning the basin. It is better to pay attention to not removing all the old soil, but adding a small amount of base fertilizer into it, and then watering.

Main points of propagation: cutting, grafting and sowing are commonly used in winter tolerance.

1. Cutting. The suitable cutting time in East China is mid June and late June. The second cutting was carried out from late August to early September. The temperature in these two periods is about 30 ° C, and the temperature can be controlled around 25 ° C with shading facilities. For cuttings, one year old semi mature branches should be selected with full crown, complete leaves, full leaf buds and no diseases and insect pests.

2. Sowing. In October, in the first and middle of October, the harvested fruits were placed in the ventilation room and dried in the shade. After the capsule cracked and the seeds were taken out, the seeds were sown immediately. If it can't be sown immediately in autumn, it should be stored in sand until February next year. Generally, the germination rate of autumn sowing is higher than that of spring sowing.

3. Grafting. The seedlings were grafted with rootstocks and buds. The seeds grew about 2 months after sowing in the sand bed. The seedlings were 4-5 cm in height, which could be dug out and grafted by splitting method.

Pest control: Camellia anthracnose, camellia cake disease; common pests are red spider and scale insects. Prevention and control methods: 40% Omethoate EC 1000 times liquid spray control or wash clean. In Meiyu season, the air humidity is high, and anthrax is often harmed. It can be controlled by spraying Bordeaux or 25% carbendazim WP 1000 times.

Winter resistant cultivation of two pink oranges: 1. Planting winter resistant flowers can be divided into garden cultivation and garden cultivation. If it is used for landscaping, shade trees should be used as companions, and shade trees should be planted in rows in nursery cultivation.

2. In the high temperature season of summer and autumn, it is necessary to shade and cool down in time. Anti freezing measures should be taken in winter. If the temperature is higher than 16 ℃, it will promote early germination.
