Pay attention to the temperature and humidity When the humidity in the booth is high, if the weather is good, let the small mouth ventilate for 15 to 20 minutes one hour after the shed is pulled, reduce the humidity in the booth, and gradually expand the ventilation. Do not ventilate when the temperature of the shelf reaches 30°C or higher to prevent the occurrence of large temperature and humidity changes. It should be noted that try not to ventilate the dew if there is dew on the melon strip and try to keep the ventilation small.
The preparation of a suitable point anther due to the emergence of some problems with anthers, often leads to the occurrence of molting in the entire shed. Due to the rapid decrease in winter temperatures, it is necessary to properly increase the concentration of anthers, but it must be promoted after the trial to avoid the appearance of anthocyanins due to excessive concentration of anthers. Overcharge 6000 times for remission.
Rational use of medicines to prevent the emergence of disease prevention and control of pesticides, many farmers believe that one or two agents are not effective, always add this point, and then add that, and sometimes even add six or seven kinds of drugs, it is very easy to cause injury. The vegetable farmer should use symptomatic medicine. Generally, 2 to 3 single agents can be compounded. It is not necessary to add too many types of agents. After the temperature is lowered, there are also vegetable farmers adopting smoke-smoke methods such as chlorothalonil smoke agent and procymidone smoke agent, but the time for smokers to smoke is usually more than ten hours, and the appropriate smoke time is six to eight hours. Generally, it is better to smoke in the shed at around 12 o'clock at night. When spraying, it is best to choose a sunny afternoon, especially after the cloudy days, to give the plants enough buffer period, the general sunny days 2 to 3 days and then spray.
