As the name suggests, greenhouse insect nets are widely used in greenhouse vegetable cultivation. Today, we would like to talk about how to safely carry out greenhouse cultivation under normal epidemic prevention conditions, and what should be paid attention to when using greenhouse insect nets during this special period.
Although it is still in the process of epidemic prevention and control, the demand for vegetables and fruits has not decreased. Growers should be fully prepared before spring seedlings and develop protective measures to prevent disease. For example, do a good job of cleaning around the nursery equipment, disinfect and sterilize the nursery equipment and the seedling stage, and set up a greenhouse agricultural insect control net of 60 mesh or more in the sand control mouth.
With the increase of the ambient temperature, it is beneficial to reasonably reduce the environmental humidity in the plastic greenhouse, and pay attention to the prevention and control of pests and diseases such as aphids and whiteflies.
In the prevention and control of the new coronavirus disease, the safety protection of employees is particularly important, which reduces the concentration of work. When inspecting the vegetable pest control net, the planters wear masks and disinfect the surface of the pest control net in time.
Since the greenhouse insect-proof net is made of polyethylene raw material, it has strong corrosion resistance, so it has a corresponding anti-corrosion effect on 84 disinfectants. The staff can safely disinfect after diluting the disinfectant in proportion, and it is not easy to affect the service life of the anti-insect agricultural netting.
In the post-epidemic era, the greenhouse insect control net has also played an irreplaceable role in planting. It provides consumers with enough vegetables and fruits to ensure the temperature and humidity in the greenhouse, thereby ensuring planting yields.
It is an important measure to complete soil layer disinfection and organic chemical weeding before covering with insect nets in the greenhouse. Bacteria and pests remaining in soil stratification need to be addressed and the transmission routes of pests isolated.
During the growing season, cover with insect nets, with very little lighting. There is no need for day and night exposure, and no need for sun and shade, and it can be covered throughout the growing season. Generally, the wind speed does not have to cross the line. In case of strong wind of 5-6 level, the network cable should be pressed tightly to prevent it from being broken by the wind. But when summer comes, the temperature is getting higher and higher. How should the greenhouse insect nets resist the wind? The specific method is as follows:
1. In order to better prevent cold air from entering the general greenhouse, all anti-air conditioning blades will be installed on the gears. In summer, we can disassemble the air conditioner blades.
2. The diamond yarn at the gate can be replaced by a low-grain diamond yarn, which will enhance natural ventilation and expand the ventilation openings.
3. If there are specifications, you can add air vents on it, and if you have specifications, you can add a centrifugal fan appropriately.
4. If the straw curtain on the greenhouse is removed, the total area of the watering gate on the top of the greenhouse can be greatly opened, thereby accelerating the emission of high temperature gases in the greenhouse.
The greenhouse insect net is a product with a net structure, and its wind resistance is not very high, so when the summer is coming, it is necessary to take certain wind resistance measures to reduce the loss of the insect net, thereby reducing economic losses.
