2021-08-05

Understand the following points [to avoid being cheated]
 
 
 
1. Has the manufacturer personally installed it for the customer?
 
2. Does the manufacturer have any application video in greenhouse?
 
3. Check the manufacturer's Wechat Friendship Circle.
 
4. Video calls must be made by Wechat with the manufacturer.
 
5. Check the relevant quality inspection report and business license of the manufacturer;
 
6. Let the manufacturer send you the video installed on the spot through the Wechat Video, whether it is consistent with myself or not;
 
7. Look at the website of the plant light supplement lamp manufacturer, whether it is professional or not.
 
 
There are a lot of vegetables watering in the greenhouse. Don't neglect these six points! Laser plant supplementary light reminds you!
 
 
 
Pay attention to growth
 
 
 
Pay attention to vegetable growth, usually when vegetable water shortage, the leaves will wilt, growth will be weakened, more diseases occur, at this time should be timely replenishment of water.
 
 
 
Pay attention to moisture content
 
 
 
Looking at the soil moisture, if the soil is not dry when watering, not only is not conducive to improving ground temperature, but also easy to lead to poor soil permeability, resulting in root anoxia, resulting in retting, yellow leaf phenomenon.
 
 
 
Pay attention to the weather
 
 
 
Water on sunny days to ensure that there are two to three sunny days after watering, so as to avoid rainy and cloudy weather after watering, resulting in increased humidity in the shed, lower ground temperature and more diseases.
 
 
 
 
Pay attention to the ground temperature
 
 
 
The suitable daily average ground temperature for vegetable growth in greenhouse is about 22 C, and the temperature in greenhouse is mostly between 15 C and 20 C. If irrigation is excessive or the timing of irrigation is not right, the ground temperature drops rapidly, causing root injury and endangering the growth of plant above ground. Therefore, low-temperature watering should be carried out in the morning after opening the weeds.
 
 
 
Pay attention to covering with plastic film
 
 
 
Plastic film can not only reduce the evaporation of ground water, maintain soil moisture, reduce the number of watering, reduce air humidity, reduce the occurrence of diseases, but also improve ground temperature and accelerate the growth rate of Cucumber in greenhouse.
 
 
 
Pay attention to post-water management
 
 
 
After watering, the first two days of noon temperature rise to about 40 degrees Celsius, stuffy shed for an hour, raise the temperature inside the shed. Then increase the ventilation rate to reduce the humidity in the shed. In order to reduce the occurrence of diseases and insect pests, spraying preventive measures should be taken against susceptible diseases.
