Selection of cucumber mulching film in Greenhouse
Vegetable growers are planting cucumbers in winter greenhouses. In order to reduce the humidity in the greenhouse, improve the ground temperature, and lay the ground film on the ground, some use the white film, some use the black film, but which kind of film is better?
The practice has proved that the use of white ground film in winter is better. The black film growers believe that the use of black film can both improve the temperature and inhibit the weeds in the spring, but it is not known that the use of white film in winter is more beneficial to the improvement of the temperature. The main purpose of using plastic film in winter is to improve the temperature and humidity. Because the transmittance of white plastic film is 80%---90%, which is conducive to raising the ground temperature. At the same time with reflective white plastic, can increase the light intensity. The black plastic film is basically opaque. When sunlight shines on the plastic film, most of it is absorbed by the plastic film and transformed into heat, and it radiates outward. Generally, the warming effect of soil is 1-2 degrees lower than that of white plastic film. 所以，菜农在冬季覆盖地模时，选用白色地膜较好。
For the measures of weeding in the spring of next year, the 2-3 leaves in the lower part of the plant can be removed when the cucumber is falling, and it can be directly dropped to the ground film, and the shade of the leaves can be used to create a light environment under the film to inhibit the growth of the weeds.
