What if the soil is hardened after planting in the pot for a long time? How to effectively prevent soil consolidation?

The demand for soil environment of the root system of each plant is somewhat different, and the quality of the soil will directly affect the growth of the plant. Therefore, according to the habits of the plant to create a suitable cultivation soil for flower growth, generally choose a better loose soil, such as yellow sand, cinder and so on to adjust to avoid the soil hard board.

Tap water contains a lot of bleach, chlorine and other substances, these substances will accelerate the speed of soil consolidation, and even the situation of salinization. Cause harm to flowers, so when using tap water to water flowers, it is best to dry them for a few days, so that the chlorine and bleach in the water can be fully volatilized to prevent soil hardening.

Turning the basin is also called turning the basin or pouring the basin. After plants have grown in the basin for 2-3 years, the basin soil lacks nutrients, accumulates harmful substances, coupled with the aging of roots, forms a thick root pad in the basin wall, resulting in soil consolidation and difficulties in nutrient absorption and transportation. At this point, we have to turn the basin. Turning the basin is usually carried out on a cloudy day or in the evening during the dormant period (deciduous period) of plants. First, the whole block of the plant was taken out of the original basin, the reticular root pad was cut off, and the original soil and root was cut off about 1 / 3, and the branches were trimmed appropriately at the same time. Then put the plants into the old or new basins, fill them with new nutrient soil (loose and fertile, breathable and permeable, rich in humus), and finally water them.

If you disrelish the trouble of turning the basin, you can use chopsticks and other tools to loosen the soil by hand, change the soil locally, or tie several vents directly to the bottom of the basin. Perlite. You can also put some perlite in the soil. Online more than 10 yuan a large bag, the original soil plus perlite is used to grow flowers, the soil will not be hardened.

It is not suitable to use chemical fertilizer. Because only cations or anions in chemical fertilizer are the elements needed by plants, plants unilaterally choose elements suitable for their own growth, resulting in soil acidification or salinization. The destruction of soil structure reduces the soil water and fertilizer conservation capacity and permeability, resulting in soil consolidation, resulting in the loss of organic matter activity, because the decomposition of organic matter is realized by the activities of microorganisms.
