In the process of planting vegetables in greenhouses, it often encounters smog and other disasters, resulting in the occurrence of illuminance in the greenhouse. Vegetable growers should know that in this environment, vegetables are not growing well. In order to reduce this kind of harm, Hui Nongwang Xiaobian will talk about the management techniques of vegetable cultivation under smoggy weather.
1. Increase lighting
The continuous smog weather will lead to insufficient light in the facility. Therefore, when selecting the shed film, it is best to choose a transparent shed film with good light transmission, dustproof, anti-aging and no dripping, and remove the dust on the shed film in time. To ensure the transparency of the shed film; at the same time, under the premise of keeping the room temperature suitable, the shed film of the greenhouse should be exposed as early as possible to extend the illumination time. Conditional vegetable nursery sites can be used to hang wall reflective screens and ground reflective films to increase light reflection and scattering.
In addition, you can also install a daylight or a hot light, and turn on the light to fill the light in the morning and evening.
2. Reasonable water and fertilizer management
During the smog weather, try not to water and fertilize to prevent lowering the soil temperature and increase the humidity in the shed. After the weather turns fine, add fertilizer to the seedlings.
3. Pay attention to ventilation and drainage
The ventilation time is preferably carried out when the humidity in the shed is the highest in the morning, or when the outside air humidity is the lowest at noon and the temperature is high. At the same time, defogging devices can be used in the shed to reduce air humidity and reduce the incidence of disease.
4. Strengthen pest control
In the haze weather, do not use foliar spray to control pests and diseases. You can use smokers and fumigants to control pests and diseases. Cross-fumigation of chlorothalonil and isoprocarb can be used.
5. Pay attention to post-clear management
After the weather has cleared, it is necessary to prevent the impact of weather on the plant by half-volume or using a shading net. It is found that the plant is wilting and the sunshade net should be put down in time; and no watering and topdressing should be carried out immediately, but it can be suspended for 1-2 days; Combined with chemical control, spraying foliar fertilizer to supplement plant nutrition.
The above is the management technology of greenhouse vegetables under the illuminating environment organized by Huinong.com, have you learned it?
