What role does PP spunbond non-woven fabric play in agricultural production?

PP spunbond non-woven fabric is based on environmental protection, it has the characteristics of degradability, UV resistance and good air permeability.

Basic functions of PP spunbond non-woven mulch:

1. Insulation and warming promote the decomposition and release of soil nutrients.

2. Moisturizing, improve survival rate. Except for irrigation, the main source of soil moisture is rain. The mulching film can effectively block the reduction of soil water evaporation, and the loss is slow; and the water droplets are formed in the film and then fall to the soil surface, reducing the loss of soil water and playing a role in preserving soil water. On the other hand, the mulch can also prevent rainwater from entering the ridge when the rainfall is too heavy, which can play a role in preventing waterlogging.

3. Promote growth and development. The application of plastic film mulch increases the temperature and humidity of the soil, which is conducive to early growth and rapid growth and promotes the growth and development of plants. The growth period of the film is shortened to about one week than that of the field without film.

4. Reduce the harm of weeds and aphids. Plastic film mulching can inhibit the growth of weeds. Generally, the weeds with mulching film are reduced by more than one-third than those without mulching. If combined with herbicides, the effect of weed control is more obvious. After spraying herbicides, the weeds covered by the film can be reduced by 89.4-94.8% compared with the weeds without the film. The mulch film has a light-reflecting effect, and can also partially repel aphids, inhibit the breeding and reproduction of aphids, and reduce the damage and disease transmission.

Therefore, in combination with the scientific development concept of green environmental protection, in the actual production of crops, the advantages and disadvantages are avoided, and feasible mulching film production technology is formulated to make full use of the role of mulching film and reduce environmental pollution.
