Mulch Film: Functions Of Mulch Film

What are the functions of mulch film?

After cultivation with mulch film, it can improve the soil and the near-surface temperature and moisture conditions, to raise the soil temperature, maintain soil moisture, improve soil properties, improve soil nutrient situation and fertilizer utilization, improve light conditions, reduce weeds and prevent pests. 

1. Heat preservation and Insulation, promote soil nutrient decomposition and release

2. Moisture, improve survival

Soil moisture, apart from irrigation, mainly comes from rainfall. With mulch film, on one hand, to reduce and less soil moisture evaporation, dissipating slowly; within membranes to form water droplets then fall into the soil surface, reduce the loss of soil moisture, play a role in preserving soil moisture storage. On the other hand, the mulch film can prevent rainwater pouring into the ridge, and play a role in stormwater drainage.

3. Promote the growth and development

Application of mulch film, soil temperature and humidity increased, conducive to the early fast, promotes the growth of plants. The film field shortens the growth period to a week or so.

4. Reduce weeds and aphids damage

Mulching can suppress weed growth. General film coated weeds are less than one-third, if combined with herbicide, weed control is more effective. After the herbicide spraying, cover film can reduce 89.4~94.8% weeds than the field without mulch film. Mulch film has a reflective effect, repelling aphids, can also partially inhibited breeding reproduction of aphids, harm reduction, and disease transmission.

5. The negative effects of plastic film mulching

Film cover effects both positive and negative, for example: film cover has water preservation function, but also it hinders outside precipitation into ridge body, part area if not take corresponding of ridge type or other measures may will led to smoke strains in long-term occurred water lost deficiency, thus affect normal growth; if encountered continuous rainfall, it is easy to cause serious water stains and makes soil permeability bad, water evaporation blocked, also affect smoke strains of growth. Therefore, combined with the practical disadvantages, develop practical production technology of mulching, make full use of the role of mulch film, adopt the corresponding technical measures are the basis of plastic film mulching planting success.

Mulch Film: Functions of Mulch Film

What land is not suitable for mulch film?

First, sand land. Mulch film can increase the temperature, but because of the sandy soil water capacity is low, huge temperature changes, after the mulch film, in the hot sun at noon, the ground temperature is too high, in case of severe drought, likely to cause crop failures.

Second, barren land. Barren lands after the mulch, not easy to catch up with fertilizer. For planting plots without enough starter fertilizer, after putting mulch film, it is not easy to reach production goals.

In the third, clay. This type of soil is difficult, not easy to find, film hard to close up with the ground when wind blowing, it is likely to blow away.

Four is the weedy land. Weeds are easy to break the films.
