The correct installation and use of agricultural film

The correct installation and use of agricultural film

Agricultural plastic film is one of the main covering materials of plastic solar greenhouses. In order to ensure its light transmittance, heat preservation and drip resistance, attention should be paid to the following points when installing and using.
1. The plastic film must be stored in a shaded, dry place before installation and use. It must not be exposed to the sun and rain.
2. The iron and metal wires in the greenhouse components should be plated and no contaminated and rusted components should be used. At the same time, the use of exposed metal wires and sharp corners should be avoided to prevent tearing of the agricultural film.
3. During the installation, the agricultural film shall be tensioned and leveled, and the agricultural film must not be installed in reverse. Otherwise, the use effect will be affected, and the service life will be reduced.
4, pay attention to the installation temperature can not be too high. When the temperature is too high during installation, the film expands due to heat. When the temperature decreases, the film shrinks and the film breaks. After the rupture of the plastic film, it is necessary to repair it with a special tape so as not to affect the function of the plastic film.
5. Before opening the film roll, the ground condition of the work should be checked to prevent the plastic film from being punctured and scratched by the object.
6, do not step on the plastic film, it should not put assembly tools or other objects on the plastic film to prevent breaking the plastic film.
7. Pay attention to avoid direct connection of agricultural film and greenhouse components as much as possible. If this is unavoidable, white acrylic acid should be applied to the joint area, not the mixed organic solvent.
8, avoid crops and irrigation, heating pipes and other equipment and film direct contact.
9, neither outside nor inside the greenhouse to burn vegetables leaves, gasoline and other items, because of its combustion products will damage the film.
10. Limit the amount of pesticides, herbicides, and biological products as much as possible, and control the concentration of sulfur-hydrogen mixture. Do not use sulfuric acid.
11, when using pesticides, to prevent spraying on the film. After using pesticides, the greenhouse should be ventilated as quickly as possible. Avoid attachment of insecticides on the membrane in contact with greenhouse components.

Foot of ningxia hong xingda incense Organic Apple fruit suborbicular, fruit surface color yellow green, most with orange chardonnay fruit surface, covered with bright red stripes, pulp yellow-white, succulent crisp, sweet, rich fragrance, quality first-class; The fruit has a sugar content of over 15%, more than 4% of the national average, and the flesh is tight and crisp and sweet, which is widely loved by consumers all over the world. There is a longer optimal consumption date than any other apple, not even refrigerated. It can be kept for 4 months at normal temperature. If refrigerated, Fuji can be kept for 5--7 months.
Altitude: high altitude area light, clean air, environment close to original condition, no industrial pollution. With an average elevation of 1160-2900m, the central health center has a strong uv light, which produces the natural pollution-free apple, which conforms to the concept of a modern green diet.
Temperature: moderate temperature can avoid the chance of fruit tree encountering disease. The average temperature in ningxia is 8.4 degrees Celsius, which has an important influence on the growth, development, yield and quality of apple. The piedmont apple is thriving in such a good environment.
Humidity environment: moderate amount of rainfall provides necessary conditions for apple's growth. The annual rainfall in the central health region is 186 millimeters. The fruit is slow to grow and the fruit is hard and hard, which fully guarantees the fruit's sugar content and the relatively average size of apples.
Sunshine condition: apple is the fruit tree, the central health area of the whole year is nearly 3,800 hours, is beneficial to the Apple Fruit coloring. The piedmont apples are red and bright.
Temperature difference factors: ambassador apple nighttime respiration weak temperature gap between day and night, consume less organic matter, the accumulation of organic matter during the day more, that apple store down a large number of glucose sugar candy, etc have better taste. The average diurnal temperature difference between apple and apple is 14 degrees centigrade, and the larger diurnal temperature difference ensures the sweet and delicious characteristics of the apple.
Other factors: frost can make apple blossom and fruit, which can cause frozen flower jelly, which is bad for apple's production. The piedmont apple has been kept at least 167 days without frost for the whole year, which minimizes the influence of apple on yield and quality.
