When we are walking on the road, we sometimes see a lot of black mulch in the greenhouse, so what is this product for and what are its advantages? Next, Qingzhou Luhong Plastic Co., Ltd. will introduce to you what are the advantages of this product?

1. Strong ability to maintain fertilizer. The results show that the total nitrogen, organic matter and alkali-hydrolyzable nitrogen content of the soil covered by it are higher than those covered by the transparent film.

2. Good water retention capacity. Tests have shown that a black plastic film covering 5cm underground, whether it is covered for 2 days or 35 days after covering, its moisture content is 4-10% higher than that of transparent film

3. To avoid bad reactions. Because of its low light transmittance and low radiation heat transfer rate, it makes the soil temperature change less per day. Experiments have shown that in the peak season of plants, the soil temperature of the soil covered with black plastic film is 1～3℃ lower than that of transparent film. Due to the small increase in temperature, it is conducive to the normal growth of crop roots, such as tomatoes, kidney beans, sweet peppers and other vegetables that do not require high soil temperature.

4. Increase vegetable output. Because the temperature covered by it is lower than that of transparent film, such as for some crops that require lower soil temperature for roots, such as tomatoes, kidney beans, cowpea, late-maturing watermelon, etc., the early yield and total yield covered by this product can be higher than that of transparent film cover. The test shows that the tomato mulching has a good effect in increasing the yield, and the yield increase rate can reach 11.8%

5. Control weeds. When using transparent film to cover, the hazard of weeds is a serious problem. After mulching with black plastic film, the growth of weeds on the ground is controlled due to insufficient light. The measurement results showed that there were no weeds in the soil after mulching with 5% light transmittance for one month. When covered with agricultural film with a light transmittance of 10%, the soil will produce weeds, but its growth ability is weak and harmless.

I hope that the knowledge shared by Qingzhou Luhong Plastic Co., Ltd. is exactly what you need. We will produce and process suitable products according to customer needs, so that customers can use it with confidence. And good after-sales service, sincerely cooperate with customers!
