Export biodegradable agricultural film white, 12um degradable agricultural PE film
12um Degradable Export Agricultural Biodegradable Laminating Film White
Introduction
The use of white mulch in winter is more conducive to raising the
ground temperature. The main purpose of using mulch in winter is to
increase ground temperature and reduce humidity. Because the light
transmittance of the white mulch is 80%---90%, it is helpful to
raise the ground temperature. At the same time, the white mulch has
a reflective effect and can
Increase the intensity of light in the shed. The black mulch film
is basically opaque. After the sun shines on the mulch film, most
of it is absorbed and transferred by the mulch film.
Turn into heat and radiate outward. Generally, the warming effect
on the soil is 1-2℃ lower than that of the white mulch. Therefore,
it is better to choose white mulch film when covering mulch film in
winter.
If it is used as a spring weeding measure, when cucumbers fall
vines, you can drop 2-3 leaves from the lower part of the plant
directly onto the mulch. Use the shading of the leaves to create a
dull environment under the mulch and inhibit the growth of weeds. .
This practice proves that it is better to use white mulch in
winter.
Specification
The function on different model mulch films.
Mulch films serve a number of different purposes. Transparent mulch film is used to encourage early season plant growth and early cropping, whereas black mulch films are used to control weed growth and white films provide reflected sunlight for the plants. In all cases, a more effective use of the available water is achieved. Most mulch films are 10 to 50 microns in thickness and used in widths up to 3 meters.
Black and Silver Mulch film is a protection cover over the soil, primarily to modify the effect of the local climate. The most powerful feature of plastic mulch is the impact it has on light. Light is responsible for creating both, heat and color. Plastic mulch can impact the development of heat increasing or decreasing it, depend on color.
The soil temperature in the planting bed is raised, promoting
faster crop development and earlier harvest.
Soil water loss reduce under plastic mulch. As a result,
irrigation frequency can be reduced
Fertilizers are optimally used and not wasted.
Soil compaction reduction: The soil under mulch remains loss and
well aerated.
Root pruning eliminated: due to cultivation eliminating.
Cleaner vegetables product: no soil is splashed onto the plant and
fruit, resulting, clean product.
The mulch film blocks the photosynthesis light. The weeds can't
survive under these conditions.
Silver and white reflect light. Reflected light seems to prevent
Aphids from seeing the plants. Yellow attracts whitefly.
