Techniques For Laying Agricultural Film
Oct 27, 2017


Agricultural film and more use of high-pressure polyethylene resin blowing from. Thickness of 0.012-0.016 mm, good transparency, warming, moisture retention performance, applicable to all types of areas, all kinds of coverage, all kinds of cultivated crops, all kinds of stubs. The theoretical amount per mu of vegetable field is about 7-8 kg.

First, the role of agricultural plastic film cover:

1, to improve the soil temperature. Agricultural mulching in winter and spring to improve the role of soil temperature and soil moisture. The temperature of the soil mulching layer of soil cover is generally 2 ℃ ~ 3 ℃ higher than the open field, which can promote the early emergence of vegetables, early development, Agriculture Mulch spring planting in advance or early planting 10 to 20 days. It should be noted that different colors of agricultural plastic film warming effect is different, the best effect of colorless film warming, Agriculture Mulch and silver-based film does not increase the temperature. Agricultural film mulching in the spring and autumn in the application of more applications in the summer should pay attention to cover time to prevent excessive damage to the ground crop.

2, inhibition of soil temperature. Summer cover film, can inhibit soil temperature rise. Such as the use of black and black and silver black double-sided film and other materials covered, Agriculture Mulch can inhibit the rise of soil temperature.

3, to improve fertilizer utilization, increase soil nutrition. Agricultural mulching can prevent sun and rain, so that fertilizer will not be lost, while improving soil temperature, strengthen the plant root absorption capacity. As the soil temperature, water conditions improved, is conducive to microbial activities, which will help promote the decomposition of soil organic matter and minerals, soil nutrients increased. Therefore, agricultural plastic film mulch can give full play to fertilizer.

4, to improve the physical properties of the soil. The soil bulk density of soil cover is smaller than that of non - covering, and the rainfall in soil is higher than that in open field, Agriculture Mulch which is beneficial to the growth of plant root. At the same time due to less water and soil loss, can prevent soil compaction, improve soil physical and chemical properties.

5, to reduce water evaporation, there is a clear role in water retention.

6, increase the light effect. The reflection effect of the transparent plastic film itself and the small water droplets attached to the agricultural plastic film increases the reflected light in the near surface, effectively changes the light condition of the crop growth period, increases the photosynthetic intensity of the vegetables, and prolongs the photosynthetic time Increased light and yield and accumulation of organic matter.

7, to prevent soil salinization. After the plastic film mulching, because the movement of soil moisture is moved from bottom to top, the surface water moisture content is high, Agriculture Mulch the relative reduction of soil salt content, which play a role in salt suppression.

8, inhibit weed growth, reduce pests and diseases. Due to the reflective properties of agricultural film, it has the effect of repelling aphids and relieving viral diseases. The experiment shows that the plastic film mulching can reduce the damage of melon thrips, obviously increase the yield and increase the economic benefit.

9, Agriculture Mulch to promote crop precocity. Due to the regulation of the plastic film mulching on the underground part and the aboveground part of the plant and the promotion of growth, the cultivation of vegetables into the product formation period is early, increasing the early production of spring crops and thus increasing the total output.

Second, the spread of agricultural plastic film method:

One by one hand on the side of the ground, the other person put the soil, compaction, and then stretched the agricultural film to continue to be placed on the ground, Agriculture Mulch continue to use soil compaction, and then covered with the edge of the soil.

Precautions:

1. Cover the nursery tray with plastic cloth;

2. Seed after the emergence of the plastic cloth broken, Agriculture Mulch so that seedlings exposed.
