Problems that should be paid attention to in raising flowers in the south and in the north

How can we raise flowers in the south? The key is to understand the natural climatic conditions of their places of origin and to master the ecological habits of each kind of flowers. specifically, it is necessary to do a good job in the four main links of soil for cultivation, water, shading and humidification, and heat preservation and cold protection.

1. To make the soil acidic, most flowers in the south like acidic soil, especially camellia, rhododendron and so on need strongly acidic soil. If the soil with high alkaline content is used for a long time to cultivate this kind of flowers, it will cause the leaves to dry tip, turn yellow and even wither, so it is an important measure to cultivate flowers in the south. Rotten leaf soil, pine needle soil, peat soil or ferrous sulfate, sulfur powder and vinegar residue can be used to improve soil.

two。 To improve water quality, most areas in the north have a high content of salt and alkali in groundwater. Long-term use of this kind of water to water flowers is easy to salinize the soil and affect the normal growth and development of flowers in the south, so it is best to use Rain Water or snow water without minerals.

3. Shading humidification North China and other places hot in summer, sunshine intensity, at this time, if the potted flowers are exposed to strong light, it is easy to cause branches and leaves withered and even burned, so summer needs proper shade. The origin of rhododendron, gardenia and other flowers not only has more rainfall, but also has more Meiyu weather, so there are often a lot of clouds and fog in the sky, making the light intensity weak. North China and other places are different. Although there is a lot of rainfall in summer, it is sunny after rain, so the light intensity is higher. Most of the flowers introduced from the south can not adapt to this kind of strong light environment, so it is necessary to give different shade to these southern plants in summer in the north, which is another important measure to cultivate southern flowers.

Most flowers in the south like the humid environment, but in the north, the climate is dry and the air relative humidity is low, which can easily cause dry tips of leaves or falling buds and flowers, so it is often necessary to spray branches and leaves with clean water in the process of maintenance throughout the year, and sprinkle water on the ground around flowerpots in summer to increase air humidity. This is not only conducive to increase leaf luster and air humidity, improve the efficiency of photosynthesis, but also reduce the occurrence and spread of diseases and insect pests, so it is also an indispensable work to raise flowers in the south.

4. Most of the southern flowers like to be warm and afraid of the cold. It is easy to suffer from the low temperature below 0 ℃ during the growth period, so it should be moved into the room for maintenance according to the temperature requirements of each kind of flowers after late autumn, and it is appropriate for general flowers to enter the house before Frosts Descent. The room temperature in winter should be treated differently according to the temperature preference of different flowers. For Milan, poinsettia, paulownia, he's impatiens, bamboo begonia, cactus flowers, etc., it should be no less than 12 ℃; medium-temperature white orchids, jasmine, Fusang, etc., not less than 5 ℃; more low-temperature sweet-scented osmanthus, kumquat, generations, such as no less than 0 ℃ can safely survive the winter. Most southern flowers have poor cold resistance, so don't leave the room too early in spring to avoid the harm of late frost and cold wind.
