White plastic mulch film is transparent, the ground temperature rises fast, spring and summer if the surface is not smooth transplanting seedlings are easy to burn, easy to grow weeds, the use is more common, pay attention to do a good job of crop germination before weeding.
Product advantages
1.Raise soil temperature. White plastic mulch film can increase soil temperature and conserve soil moisture in winter and spring. The temperature of the tilling layer of the mulch covered soil is generally 2-3℃ higher than that of the open soil, which can promote early emergence and early development of vegetables, and make spring sowing or planting 10-20 days earlier.
2.Curb drastic changes in soil temperature. Covering the white plastic mulch film in summer can inhibit the rise of soil temperature, and covering the film in winter can inhibit the fall of soil temperature.
3.Improve fertilizer utilization rate and increase soil nutrition. White plastic mulch film can prevent the sun and rain, so that fertilizer will not be lost, while regulating soil temperature, strengthen the absorption capacity of plant roots. Due to the improvement of soil temperature and water conditions, it is conducive to the activity of microorganisms, which is conducive to the decomposition of soil organic matter and minerals, and the increase of soil nutrients. Therefore, mulch can give full play to the fertilizer effect.
4.Improve the physical properties of soil. The bulk density of soil covered by white plastic mulch film is smaller than that not covered, and the oxygen content of soil is higher than that of land due to rainfall, which is conducive to the growth of plant roots. At the same time, due to less water and soil loss, it can prevent soil hardening and improve soil physical and chemical properties.
5.Reduce water evaporation, reduce field temperature, reduce disease occurrence, and also have obvious water retention effect.
Increase the light effect. For example, the reflection of the transparent film itself and the small water beads attached under the film 6.Increases the reflected light near the surface, effectively changes the light conditions during the growth period of crops, improves the intensity of crop photosynthesis, prolongates the photosynthesis time, and thus increases the light and yield as well as the accumulation of organic matter.
