Export quality black biodegradable mulch, environmental protection, green thickness 12um,Weeding black film
Green Thickness 12um Metalized PE Film , Black Biodegradable Mulch Film
Black film for agriculture
1. Insulation performance of black mulch film After 10 days of
vegetable planting, the average ground temperature of black mulch
is 11.8℃ during the day, which is 1.88℃ lower than that of white
mulch. The average temperature of black mulch is 8.8℃ at night,
which is 1.44℃ higher than white mulch. In the survey 60 days after
planting, the average ground temperature of the black mulch during
the day was 22.5℃, which was 2.6℃ lower than that of the white
mulch, and the average temperature of the black mulch was 16℃ at
night, which was 1.7℃ higher than that of the white mulch.
2. The weeding effect of black mulching film. Two black mulching
films of different shades used in a large area have weeding
effects. The lighter black mulching film has grass under the
pre-film, but it died soon, while the darker black mulching film
There are no weeds in the field, which reduces the consumption of
nutrients and water by weeds, which not only saves labor and
effort, but also avoids the contamination of soil and vegetable
fruits by chemical herbicides.
3. Root system development After 60 days of planting various
vegetables, the survey of root system growth and development showed
that the average number of roots of various vegetables covered with
black plastic film in the protected area was 36.5, and the average
number of roots in open field was 34.2, which was 5.4 more than
that of white plastic film. Roots, 3.6 roots, strong and developed
root system. Therefore, all kinds of vegetables covered with black
plastic film have deep roots and luxuriant leaves and strong
disease resistance, which can extend the growth and fruiting period
by 12-15 days than that covered by white plastic film, laying the
foundation for high yield. In addition, the eggplant skin covered
with black mulch is shiny, the beans are long and tender green, the
potato skin is white, the starch content is high, and the product
has a high commodity rate.
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.
