【COVERING FILM】As the development of science and technology is so rapid, the planting Technology of greenhouse is also more and more clever, lots of planter  is imitating  the planting method of greenhouses covering film. 

Covering Film

ADVANTAGES:

1. IMPROVE THE TEMPERATURE IN THE SHED: reduce water evaporation, play the role of heat preservation and warming.

2. KEEP SOIL MOISTURE: blocked by the film and on the surface of the film into water droplets and drops back to the soil, so that the water is moving up and down, so that the soil is evenly moist.

3. KEEP THE SOIL LOOSE: after building the shed, avoid the soil compaction brought by rain erosion.

4. ACCELERATE THE TRANSFORMATION OF SOIL NUTRIENTS and improve the utilization rate of soil nutrients

5. IMPROVE THE YIELD AND QUALITY OF VEGETABLES

6. BRING VEGETABLES TO MARKET EARLY

7. REDUCED THE IMPACT OF DISASTERS

DISADVANTAGES:

1. LESS LEACHING, SOIL IS EASY TO PRODUCE SALINIZATION: Because the fertilizer in the shed is less leaching by rain, the remaining fertilizer and salt will move upward with the movement of water, and accumulate in the soil layer, causing high concentration of salt harm, so that the growth and development of crops is hindered.

2. SINGLE VARIETIES, LARGE PEST BASE: vegetable varieties planted in greenhouses are often relatively single, and the phenomenon of crop planting in the same family is relatively common, which is easy to cause the increase of pest base, and even the "self-toxic phenomenon" of crops.

3. INCREASED PRODUCTION INPUT AND HIGHER PRODUCT COST.

4. UNCONDUCIVE TO MECHANICAL OPERATION.

5. UNCONDUCIVE TO VEGETABLE PHOTOSYNTHESIS.
