What are the maintenance and maintenance and lighting skills of greenhouse film
The cover insulation material of the greenhouse can be made of film, glass, PC board, etc. However, in my country's agricultural production bases, due to cost and technical constraints, most agricultural production will choose film as its covering material. How to do a good job in the maintenance of the film is also what every agricultural production manager needs to know.
1. When covering the film, the stent should keep the surface smooth. Where the stent is combined, bandaging measures should be taken to prevent the loss of the device to the film.
2. In some corners or places that need to be fixed, attention should be paid to the protection of the membrane
3. Try to use the same old and new films as possible to avoid the new ones being corroded by the old ones.
4. When ventilating, the roll film should be careful.
5. Pay attention to cleaning the garbage on the film to avoid sharp objects from scratching the film.
6. In summer, especially in this high temperature season. Do a good job in the sunscreen of the film. If the stent is made of metal, more attention should be paid to the damage to the film caused by the metal temperature.
7. In winter, do a good job of anti-freezing of the film. The lower greenhouse makes the film prone to breakage.
8. If there are small cracks or holes in the film, don't feel that you don't care, you should repair them in time. Avoid creating larger rips.
9. When cleaning the film, try to use a soft brush, do not use too much water pressure when cleaning, and clean each area one by one.
10. If the film is slack, it should be tightened in time. The slack film is easily broken under the action of strong wind.
There is no doubt about the importance of light to the growth of crops, so how should we maintain sufficient light when planting crops? According to user feedback and user experience, the following simple methods to maintain sufficient light are summarized:
1. To ensure that the greenhouse can have sufficient light, attention should be paid to the site selection of the greenhouse construction, and the factors such as water source, light, transportation and other factors should be comprehensively considered. To be able to receive sufficient sunlight.
2. Try to choose a bracket structure with a smaller area in the selection of bracket materials, so as to avoid the bracket from covering too much sunlight, and at the same time, it must also meet the requirements that the bracket can withstand a certain weight and the attack of strong wind.
3. In the selection of covering materials, try to choose a drip-free film, which can prevent the light transmittance from becoming poor due to the adhesion of water droplets.
4. The crops should be planted reasonably. When transplanting crops, if they are the same crops, try to make them the same height as possible, so as to avoid blocking the sunlight between crops. If the conditions are good, the crops can be mixed to make full use of the space.
5. Regularly clean the dust and dirt on the surface of the film. The stains on the film can easily cause the sunlight to not fully irradiate the greenhouse. Especially after snowing in winter, the snow on the surface of the film should be cleaned in time to ensure that the greenhouse Can get enough light.
6. In cloudy and rainy days, artificial light is used to increase the light intensity. If the greenhouse cannot get enough light due to the weather, then appropriate supplementary light measures should be taken to avoid the crops being unable to grow smoothly due to lack of light.
