The soil structure is damaged, the tillage layer becomes hard, and the ventilation and water permeability are poor, which seriously affects the normal growth of crop roots. Serious shortage of organic fertilizer input: the soil organic matter content is low and the structure deteriorates, which affects the activity of microorganisms, thereby affecting the formation of soil aggregate structure and leading to soil compaction.
Agricultural measures such as repression, tillage, and flood irrigation led to the destruction of the aggregate structure of the upper soil. Root vigor decreases, causing nutrient deficiency. In the case of soil compaction, the lack of oxygen in the soil will lead to a decrease in root activity, unable to absorb nutrients normally, and cause nutrient deficiency.
Long-term application of large amounts of acidic fertilizers, such as potassium sulfate, ammonium sulfate, ammonium chloride, etc. After soil acidification, the number of beneficial bacteria in the soil decreases, and the population of harmful microorganisms increases, thereby increasing the incidence of root diseases. The use of chemical fertilizers should follow the principle of "a small amount is effective, an appropriate amount is the best, and an excessive amount is harmful", and it is best to carry out soil testing and formula fertilization.
The use of microorganisms in the soil has many benefits, and everyone is already aware of the benefits of improving soil aggregate structure.

If the soil quality is not good, it is likely to lead to the loss of organic matter in the soil when growing crops. In rural areas, crop rotation can be carried out as a way to restore the fertility of the soil.

How to distinguish good soil (fermented soil) and bad soil (putrid soil):
1.Hold some soil in a glass container, add water and leave it for a few days, then filter it with filter paper to observe the transparency of the water. If the water is very turbid at this time, then it is a putrefactive soil.
After a few more days, the water will become more transparent in the case of fermentation and synthetic soil, and in the case of rotten soil, the water will become more turbid and begin to emit a foul odor and finally turn into rotten water.
2.Put the water and soil together in the bottle, close the cap, and place it tightly, if it turns red, it is fermented soil, if it turns blue, it is spoiled soil, which is also a method of identification.

The pastoral soil in the north is alkaline, not only the soil alkaline water is also alkaline, so it is just to improve the soil and not pay attention to the water for watering, so after a long time, it is still the same to make your flower soil alkaline, so if you want to completely improve the living environment of flowers, you should start from two aspects.
First, the problem of soil balance, for plants that like acidic soil, such as rhododendrons, etc., you can change pots every spring, go to the flower market to buy the kind of soil that is rotten with pine branches, or go to the place where there are pine trees to dig the black mud-like soil under the pine trees. Most flowers can still be grown in a neutral or slightly alkaline environment.
Second, the aspect of water, in fact, the aspect of water is easy to be ignored by everyone, and the degree of damage to acidic soil by alkaline water is also considerable. If there is no water treatment, you can let the hall mix the appropriate amount of white vinegar in the water every time you water the flowers, so that it will not be too wasteful and solve the water problem. Or use some fresh rice washing water when watering the flowers.
If you want to have fun, talk to your friends.

The most important thing about not being able to speak is related to your knowledge, so as long as you strengthen the study of knowledge, you will become able to speak, because people with knowledge and a wide range of knowledge must know what is and what to say on what occasion!
