After entering October, the weather began to slowly cool down. As the season changed, the temperature and the light changed, the vegetable shed film also entered the replacement season. However, when the shed film was replaced, some small details were not realized by many farmers. After the replacement of the film, various problems frequently occur, so the greenhouse also needs to master the skills to change the film. Xiaobian reminds the vegetable farmers to pay attention to the following precautions when changing the film:
First, prepare the work in advance when changing the film
1. When changing the film, you need to pay attention to the weather in advance. Avoid changing the film on rainy days and windy weather. Choose a sunny afternoon to change the film.
2, many vegetable farmers are used to prematurely remove the old film when changing the film, and then start preparations for the replacement of the new film, the intermediate time is long, many pests and germs outside the shed are easy to move into the shed, therefore, change When preparing the membrane, the preparation should be done first. After all the preparations are completed, the old membrane is removed, and then the new membrane is replaced immediately, so as to minimize the membrane change time.
Second, pay attention to the maintenance of bamboo poles and steel wire when changing the film
Many vegetable farmers only changed the new shed film when changing the film. The old bamboo rafts and steel wires on the original shed were not observed in advance to see if they needed to be replaced. As a result, when the snow was changed in winter after the film change, the shed film pressure was too heavy, and the old bamboo rafts and steel wires were too heavy. Can not withstand these pressures, the shed collapsed. Therefore, remind the farmers that when changing the film, they must carefully check whether the bamboo rafts or wires of the shed need to be replaced. If they need to be replaced, they should be replaced at the time of film change to avoid various problems in the later period.
Third, pay attention to the prevention and control of pests and diseases after changing the membrane
After replacing the new membrane, many vegetable farmers neglected the prevention and control of pests and diseases, because many pests or germs, especially some moth pests, would enter the plant and weed on the plants or weeds in the greenhouse. Prompt spraying and prevention, pests and diseases will occur seriously, therefore, within 1-2 days after the membrane change, according to the weather conditions, timely spraying some preventive pests and diseases to avoid the occurrence of pests and diseases.
