What are the four points to pay attention to when playing pesticides in summer?
The use of chemical fertilizers in agriculture and animal husbandry is large and frequent, especially in summer, plants grow rapidly, and the probability of diseases is also increasing, so chemical fertilizers should be sprayed frequently in summer to ensure safety. When spraying chemical fertilizers in summer, I basically choose chemical fertilizers that can exert their efficacy quickly, and minimize the use of those that take a long time to exert their efficacy slowly.
There are many kinds of fertilizers, because I firmly believe that even farmers who have worked all their lives can't count. Various fertilizers solve various diseases, and sometimes there may be several or more fertilizers for a disease or pest to choose from. Under the condition of ensuring the quality of chemical fertilizer, I usually choose a chemical fertilizer that can exert its efficacy quickly in summer. Can improve the effectiveness of chemical fertilizers. At the same time, the climate in summer is unpredictable, and the efficacy cannot be fully exerted on time. It is very likely that there will be no drug effect after a storm, and it will be sprayed again, which will consume both manpower and material resources.
Spraying chemical fertilizer in summer must ensure safety, especially the safety of employees. It's hot at the beginning of summer, so don't spray chemical fertilizer at noon. At noon, Sunshine Film was in full swing, which was a great test for the staff. It is easy to be poisoned by traditional Chinese medicine or drugs. The weather is hot, so we should try our best to reduce field work, but farmers can't avoid it, so we must strengthen safety protection for such a long time.
When spraying pesticides, you must wear a hat, protective mask and rubber gloves to avoid skin contact. At the same time, the temperature is high, and fertilizer is likely to be uncertain. Excessive inhalation of chemical fertilizer sprayer may lead to poisoning of workers. When spraying, try to avoid fog and inhale as little as possible to prevent poisoning. Summer is not only hot, but also changeable in temperature. Before spraying chemical fertilizer, we must pay attention to the weather changes to prevent sudden precipitation and make chemical fertilizer lose its legal effect. When choosing quick-acting fertilizer, we must choose the time of spraying fertilizer. The key is to care about the change of weather.
The weather forecast must be watched, although it is forbidden in most cases. Before I spray pesticides, the key is to see what the blue sky color is. If it doesn't rain in 3-4 hours, I'll start spraying fertilizer.
The climate in summer is changeable, so it is the biggest rival of spraying chemical fertilizer. Sometimes, just a few minutes after taking the medicine, a car crash and a rainstorm will make us in vain. Therefore, before spraying chemical fertilizer, it is necessary to find out the duration of drug effect and the time of rain. It is not necessary to do it in vain just after spraying heavy rain. When spraying chemical fertilizer in summer, try to dilute the concentration of chemical fertilizer while ensuring the efficacy. Temperature, fertilizer and food crops are all variable, and the concentration of diluent can reduce the risk and ensure the safety factor of workers to improve.
High temperature is not only an exercise for people, but also an exercise for fertilizers and food crops. Even the commonly used chemical fertilizer may have uncertain elements under the action of high temperature, so the concentration of chemical fertilizer should be diluted as much as possible under the condition of ensuring the drug strength. At the same time, the digestion and absorption of food crops are accelerated at high temperature, and the growth and development are also accelerated. At this time, the concentration of chemical fertilizer should be reduced to prevent fertilizer damage to crops.
Similarly, under the action of high temperature, chemical fertilizer is likely to fully play its role faster, and human skin will digest and absorb it faster after contact. Reducing the concentration of chemical fertilizer can also ensure the safety of operators to a certain extent. When the weather is hot, crops will enter a rapid growth period, and at the same time, summer is also a link where diseases are concentrated, which determines that we should spray pesticides frequently. Spraying chemical fertilizer in summer actually stipulates two key drugs and ensures the safety of workers, among which ensuring the safety of workers is the most important.
