The main function of non-woven mulch
PP non-woven mulch film has a variety of physiological and ecological effects, such as breathability and hydrophilicity, temperature increase, moisture preservation, no-tillage, fertilizer increase, prevention and reduction of pests and diseases, etc., which can increase the survival rate of young fruit trees, accelerate growth, and benefit It has significant effects on flowering and fruiting and improving fruit quality; it also has economic effects such as saving water, electricity, labor, fertilizer, and pest control costs.
The role of weeding non-woven mulch:
1. Inhibit the growth of weeds: Cover with black weed-proof film. After the weeds germinate, the photosynthesis will be inhibited because they cannot see the light, and they will inevitably die. The effect is very good!
2. Raise the ground temperature: After the ground is covered with mulch, the mulch can block the soil heat from radiating outwards, and can raise the ground temperature by 3 to 4°C.
3. Keep the soil moist: After the ground is covered with mulch, it can inhibit water evaporation, maintain a certain soil moisture, and reduce the number of watering.
4. Maintain soil looseness: After the ground surface is covered with plastic film, watering can be carried out by ditching between rows, and the water penetrates laterally into the roots under the canopy, and the soil layer under the film is always loose without compaction.
5. Improve soil nutrition: early spring mulching with plastic film can increase ground temperature, stabilize soil moisture, and create good conditions for soil microbial activities, thereby accelerating the decomposition of soil organic matter and increasing soil nutrient content.
6. Prevent and reduce pest damage: After mulching in early spring, it can prevent many pests that overwinter in the soil under the tree from unearthing, prevent and reduce the reproduction and infestation of pathogens in the soil that harm fruit trees, thereby preventing and reducing pests and diseases. Occurrence and development. For example, peach heartworm and paramecium have the habit of overwintering underground, and mulching film in early spring can prevent such pests from unearthed and harmed. In addition, mulching improves the environmental conditions of root growth, makes the tree robust, and can greatly improve the disease resistance of the tree.
