It is made of polyethylene resin by blow molding. With good transparency, warming and moisture retention, it is suitable for various regions, various covering methods, various cultivated crops and various stubbles.
Blow molded by adding a certain proportion of carbon black to polyethylene resin. The black mulch can block sunlight, make it difficult for the weeds under the mulch to photosynthesize and grow, and has the function of weeding. It is suitable for ground cover or softening cultivation in areas and seasons with heavy weeds.
A certain proportion of dripping agent is added to the mulching film to make the mulching film have a certain dripping function. The light transmittance of the mulch is good, and the light transmittance is more than 10% higher than that of the ordinary mulch. The ground temperature rises quickly, which is more obvious than ordinary mulch. Very suitable for use in the shed.
The mulch film not only reflects visible light, but also reflects infrared and ultraviolet rays, and has stronger cooling and moisture preservation functions. It also has a strong function of repelling aphids and preventing viruses. It also has a certain promotion effect on the synthesis of anthocyanins and vitamin C. It can block light and weeding and reflect light to increase the photosynthesis of plant leaves.
Special mulching film developed based on the thermotaxis of vegetable crop roots. Usually black and white, with white film tape for cultivation rows, and a black film tape between the rows. In this way, the white film belt has a good warming effect, which can promote early growth and rapid growth in the early stage of crop growth. Although the black film belt has a poor warming effect, it is far away from the crop rhizosphere and basically does not affect the early maturity of vegetables. Features. In the high temperature season, the ground temperature between rows can be reduced, and the root system can be induced to grow between rows, which can prevent premature aging of crops.
The herbicide-containing side is attached to the ground. When the vaporized water evaporated from the soil condenses into water droplets on the surface of the film, the herbicide is dissolved in the water and dripped into the soil surface to form a herbicidal soil layer. The film has three functions at the same time: warming, moisture preservation and weed killing.
According to the requirements of different crops for the distance between plants, the mulch film is perforated during the production process. The user avoids manual drilling again during use. Thereby reducing the amount of labor.
This kind of mulching film can degrade by itself after a period of time. Prevent residues from polluting the soil. The induction period of the degradable mulching film can be stably controlled for more than 60 days; the degraded film does not hinder the elongation of crop roots and does not affect the movement of soil water.
