1, change soil in time: When raising flowers and plants, it is necessary to change soil frequently.Generally, soil should be changed once a year or two or three years.The soil should be loose, breathable and fertile, and the soil should be loosened frequently during the management period, so as to avoid soil compaction and promote better absorption of water and nutrients by plants.
2. Add microorganism agent: The microorganism agent in the soil will be washed away when watering, and many microorganisms will flow out from the outfall, and the soil will be hardened after a long time.Microbial agents should be added to the plant regularly, about once every three months, to avoid hardening.
3. Scientific fertilization: If inorganic salt fertilizer is often applied during the management period, it will be easy to harden for a long time.Attention should be paid to the application of organic fertilizer, less inorganic salt, and foliar fertilizer, so as to avoid hardening and reduce soil damage.
Usually, when cultivating plants to prepare soil, a proper amount of coal cinder, fermented sawdust or charcoal should be mixed into the soil, so as to improve the air permeability of the soil and avoid hardening.If there are conditions, you can find some rotten leaf soil mixed in, pay attention to the use of pre-drying must be done to avoid there are eggs or bacteria.In addition, if you use tap water when watering, you should dry it for a day before using it, and volatilize the chlorine contained in it, which can also avoid the phenomenon of hardening.
