1, water.
When to water it?
First of all, the most intuitive look at the soil is indeed a signal that the soil is cracked and the pot is light, so it can be judged that it can be watered. But more fundamentally, we raise meat, not soil. Looking at the performance of plants, we can know more intuitively whether there is water shortage, the leaves are soft and wrinkled together, and the whole plant is a little wrapped up, indicating water shortage. At this time, we can water it. Therefore, it is more reasonable to water the plants, and it can also be unaffected by the road surface and weather.
Water. What?
Water quality is nothing more than pH value and hardness. Rain is acidic, tap water should be almost neutral, but tap water contains a little chlorine, so it is better to put it aside and wait for it to evaporate. Secondly, putting it aside can make the water temperature closer to the soil temperature without causing a big change in the rhizosphere temperature. What plants are most afraid of is the great changes in the environment. Remember, remember. Students in the north should also pay attention to the fact that the water in the north is hard and alkaline, so directly pouring tap water may not be able to raise southern plants that like acidic soil, such as azalea (details), jasmine (details) and Phalaenopsis (details).
How to water it?
Generally, there are two ways to water flowers, direct watering and soaking in pots. There's nothing wrong with being direct. It is permeable. Bath basin can't be used often, because the soil evaporates after absorbing water, and water and alkali will stay in the soil, and the soil will become alkali after a long time. This is also the reason why if you don't do it, you will fall completely. Generally, when planting or transplanting plants, you should use a soaking basin so that the seedlings will not be washed away.
2. Lighting equipment
It takes photosynthesis to make plants, so it is nonsense for me to say that plants like light. Are there people who don't like food ... it's just that they have different tolerance for shade.
As I said before, the five elements interact with each other, and places with strong light often lead to an increase in the temperature and a decrease in the humidity of the local microenvironment. Therefore, under the influence of temperature and humidity, some plants may prefer scattered light to direct light.
luminous intensity
You don't need to know much about raising flowers at home. The intensity of direct light is greater than scattered light, so it is better for people with meat to direct it. However, except for plants with poor root growth, strong light adjustment will lead to plant water evaporation, while the newly transplanted fleshy roots grow poorly and cannot absorb water from the soil. Strong light can kill plants, so start with bright scattered light and then gradually turn to strong light.
Light quality
Pot friends will find that it is better to put the meat outside through the glass in the window. In addition to the influence of ventilation, glass also isolates some ultraviolet rays, which can inhibit internode elongation, prevent overgrowth and make the plant shape more compact.
However, it is best to move from indoor to outdoor slowly, giving plants an adaptation process. After all, they are most afraid of great changes in the environment. From outdoor to indoor, there are great differences in light, temperature and ventilation, and it's okay to get sunburned at first.
3. The problem of air humidity.
For meat, air humidity is not so important, but it is also very important. Many pots of friends' meat died in summer, some said it was drowned by water, some said it was black rot ... in fact, it was not drowned. As long as your basin is perforated and not soaked in water, there will be no water and there will be no fleshy water.
This is still related to the increase of local air humidity after watering. If your meat is still in a room without air circulation, the humidity will be higher. Then in summer, high temperature, high temperature and high humidity lead to fungus jumping, while plants grow slowly and their resistance decreases in summer, so tragedy happens ... If one of high temperature and high humidity is controlled, tragedy can be avoided. Therefore, shading and ventilation is king in summer, which is the simplest and most commonly used means to reduce temperature and humidity.
4. Soil and matrix problems.
Two important indicators to measure soil are water holding capacity and porosity, and they are in opposition. Simply put, water retention with good air permeability is not good, and water retention with good air permeability is not good. Good soil is to find a balance between the two, so as to keep water and breathe freely. We can feel the soil loose and fertile, soft and moist without hardening.
There is also the concept that matrix and soil are different. There are many kinds of substrates, such as peat, perlite, coconut bran and so on. Compared with garden soil, when the matrix is mixed in a certain proportion, it has high organic matter content, light weight and good water retention performance. Merchants use substrates to grow flowers mainly because the substrates are light and the transportation cost will be much lower.
Garden soil is recommended for family flower cultivation, because garden soil is rich in minerals, which the substrate does not have, and can exercise the root system of plants to make it stronger, which is also beneficial to flower growers to control watering. We all know that peat is not easy to absorb water when it is dry.
Fertilization is a key step in raising plants, but you don't need any fertilizer to eat more meat, you can skip it.
