In fact, the climate, precipitation and altitude of flowers are all restrictive factors. Some plants are very adaptable and can be seen all over the country, so the soil cannot be regarded as a whole. Only the representative plants and flowers in the corresponding soil are listed above for reference. When planting, we should combine the local specific conditions and the corresponding flowers before making a choice.
First, the relationship between soil physical properties and flowers
Soil minerals are the basic substances that constitute the soil, and the soil texture is different with different content and particle size. Generally, soils are divided into three types according to the diameter of mineral particles: sandy soil, clay and loam.
(1) sandy soil
The soil is coarse in texture, rich in sand, large in gap between soil particles, loose, strong in permeability and good in drainage, but poor in water retention and prone to drought. The soil temperature is greatly influenced by the environment, and the temperature difference between day and night is large; Low organic matter content, fast decomposition, strong fertility but short fertilizer efficiency are often used as ingredients for cultivating soil and improving clay, and can also be used for cutting, sowing substrates or cultivating drought-tolerant flowers.
(2) Clay
The soil is fine, the gap between soil particles is small, it dries and hardens, and too much water is too sticky. It contains more mineral elements and organic matter, and has strong water and fertilizer conservation ability and long fertilizer efficiency. However, poor air permeability, poor drainage, small temperature difference between day and night in soil, slow rise of soil temperature in early spring and slow growth of flowers are particularly unfavorable to seedling growth. Except for a few flowers who like cohesive soil, most flowers are not suitable for this kind of soil and often need to be used in conjunction with other soils or substrates.
(3) loam
The soil texture is uniform, the soil particle size is moderate, the nature is between sandy soil and clay, the organic matter content is high, the soil temperature is relatively stable, it not only has good ventilation and drainage ability, but also can retain water and fertilizer, which is beneficial to plant growth and can meet the requirements of most flowers.
Soil air, moisture and temperature directly affect the growth and development of flowers. The amount of water and air in soil is mainly related to soil texture and structure.
Plant roots consume a lot of oxygen when breathing, and most microorganisms in the soil also consume oxygen, so the oxygen content in the soil is lower than that in the atmosphere. The oxygen content of soil is generally 10 ~ 2 1%. When the oxygen content is above 12%, most plant roots can grow and regenerate normally. When the concentration dropped to 10%, the normal function of most plant roots began to decline. When the oxygen content drops to 2%, the plant roots can only survive.
The amount of water in the soil is closely related to the growth and development of flowers. When the water content is too high, all the gaps in the soil are occupied by water, and the roots rot because of lack of oxygen. In severe cases, leaves turn green and plants die. A certain water deficit forces the roots to develop into deep soil, and at the same time, there is sufficient oxygen supply, so the roots are often developed. Flowers growing in cohesive soil often suffer from physiological drought in summer because of too much water and insufficient oxygen supply to their roots.
Soil temperature has great influence on seed germination, root development and seedling growth. Generally, when the ground temperature is 3 ~ 6℃ higher than the air temperature, the survival rate of cutting seedlings is high. Therefore, most breeding beds are equipped with devices to increase the ground temperature.
Second, the relationship between soil chemical properties and flowers
Soil chemical properties mainly refer to soil pH value, soil organic matter and soil mineral elements, which are closely related to the nutritional status of flowers. Among them, the influence of soil pH on flower growth is particularly obvious.
Soil pH value generally refers to the concentration of H in soil solution, which is expressed by pH value ... The pH value of soil is mostly between 4 and 9. Soil pH is related to soil physical and chemical properties and microbial activities, which affects the decomposition and utilization of soil organic matter and minerals. The effect of soil pH on plants is often indirect. For example, in alkaline soil, it is difficult for plants to absorb iron, which often leads to the lack of green for acid-loving plants.
There are three kinds of soil reactions: acidic, neutral and alkaline. Too strong pH is not good for plant growth, and even leads to death. The adaptability of various flowers to soil pH is quite different, most of them require neutral or weakly acidic soil, and only a few can adapt to strong acidic (pH 4.5 ~ 5.5) and alkaline (pH 7.5 ~ 8.0) soil. According to the requirements of flowers for soil acidity, it can be divided into three categories:
(A) acid soil flowers
Flowers that grow well in mild or severe acidic soil. The pH value of the soil is lower than 6.5. Because of the different kinds of flowers, the requirements for acidity are also quite different, such as bromeliad, fern, orchid, gardenia, camellia, rhododendron and so on, while cyclamen, Zhu Dinghong, begonia, citrus and palm are relatively loose.
(2) neutral soil flowers
Flowers that grow well in neutral soil. The pH value of soil is between 6.5 and 7.5, and most flowers belong to this category.
(3) alkaline earth flowers
Flowers that can tolerate soil above pH7.5, such as carnation, sweet pea, gerbera, geranium, etc.
Selection of soil for potted flowers
Because the roots of potted flowers can only move in a small soil range, the requirements for soil are stricter than those of open-air flowers. On the one hand, the nutrients should be as comprehensive as possible, and the limited pot soil contains the nutrients needed for flower growth; On the other hand, it requires good physical and chemical properties, that is, loose structure, strong water retention, moderate pH value and good fertilizer retention.
Because of this, neutral or slightly acidic soil with good aggregate structure, loose and fertile soil, good water retention and drainage performance and rich humus should be selected as far as possible when planting flowers. This kind of soil has light weight, large pores, good air circulation and rich nutrition, which is beneficial to the root system development of flowers and the robust growth of plants. If flowers are planted in cohesive soil with poor ventilation and water permeability, or in pure sand with poor nutrition and poor water and fertilizer conservation, or in alkaline soil, it will easily lead to weak growth and even death for most flowers.
But the soil conditions mentioned above are not available in any natural soil. Therefore, the soil of potted flowers needs artificially prepared culture soil. This kind of culture soil is made by mixing more than two kinds of soil or other matrix materials in a certain proportion according to the different growth habits of flowers to meet the needs of different flowers.

After the land is planted with flowers, can it still produce food? Generally, the land where flowers are planted will not be suitable for growing flowers in a few years. Hello, landlord, what you may be worried about is the problem of "continuous cropping" Personally, it is no problem to plant wheat and corn after planting flowers if reasonable fertilization management can be achieved. As for the problem that flowers will crop again after several years of planting, it is really not clear. There seems to be a big flower market in Qingzhou. You can go on a field trip if you have the conditions. I hope it helps you.
