Why do you lay a mulch in the garden
Organic coverage is made of various organic biomas. It is crushed and placed on the surface of the soil surface around gardening plants and trees. It absorbs dust, adjusts temperature, maintains soil moisture, improves soil fertility, suppresses weeds, and promotes plant growth.
1. Keep soil moisture
Organic coverage reduces the evaporation by improving the permeability of water and water retention, and suppress weeds to maintain soil moisture. Many research reports show that the soil water can increase by 35%to 200%compared with the exposed land. Of course, everyone What needs to be known is that although organic coverage can save the water in the soil, it also needs to be irrigated regularly. Otherwise, the plant may face drought after the water is completely evaporated.
2. Adjust the temperature of the soil
The best temperature for tree roots is 15 degrees Celsius -25 degrees Celsius. The soil temperature exceeds 35 degrees Celsius, and the root system of the plant will stop growing. In the summer, the city trees are easily affected by the heat island effect, causing shallow roots to burns, affecting the growth of trees, and death. Organic coverage keeps the surface soil temperature in the surface of 6 degrees Celsius ~ 8 degrees Celsius, which has a thermal insulation effect in the cold winter.
3. Reduce soil erosion and urgency
Organic coverage has a good buffering effect on the cleaning of heavy rain and irrigation, effectively preventing soil loss, and the tightening of organic coverage prevention. Of course, it is necessary to know that organic coverage can only play a certain buffer to a certain buffer In the process of actual use, if you want to achieve better use effects, you need to use some professional means to prevent soil loss.
4. Increase soil nutrients
In the process of organic coverage, potassium, manganese, calcium, and other mineral nutritional elements can be released to increase soil organic matter.
5. Reduce soil salt points
Application of organic coverage can improve soil pH, reduce soil moisture evaporation and the fixed ion fixation of organic coverage. Due to the impact of urban environment and long -term use of wastewater irrigation, the concentration of salt ions in urban soil has increased. In the application of urban greening, the management costs such as irrigation, fertilization, and weeding are effectively reduced, and the damage to trees such as cutting machine cutting machines is avoided, the plant survival rate is improved, the growth and health of the trees are promoted, and the growth of the trees is improved.
The production of organic coverage is relatively simple. Some ordinary organic coverage can be made with fruit shells and then used to raise flowers
