Degradable agricultural mulch can keep warm and moist, promote the decomposition and release of fertilizers in the soil; after laying the mulch, it can block the evaporation of water in the soil and reduce the loss of soil moisture; it can also play a role in preventing waterlogging when the rainfall is too heavy.
Degradable agricultural mulch can improve the utilization rate of fertilizers and increase soil nutrition. Mulch covering can prevent sun and rain, prevent fertilizer loss, and at the same time increase soil temperature and enhance plant water absorption capacity. Due to the improvement of soil temperature and moisture conditions, it is conducive to the activity of microorganisms, promote the decomposition of soil organic matter and minerals, and increase soil nutrients. Therefore, mulch covering can give full play to the fertilizer effect.
