Recently, the party master of Datian Township, Shouguang City, reported that some time ago, he heard that cucumber bagging could increase the quality and sell high prices. He also tried to put cucumbers in bags. He only had more than 100 cucumbers and wanted to see if it was feasible. The results of the 100 sets of cucumber without exception were infected with disease, light water stains like lesions, serious has begun to rotten melon, it is clear that cucumber infection is a bacterial disease. However, no bagging cucumber found no disease. After knowing the situation in detail, the experts believe that cucumber disease is caused by mistakes made by the master chef when bagging cucumbers. So, what problems should you pay attention to when bagging cucumbers? First of all, we should pay attention to the time of bagging should be selected after 10 o'clock in the morning or afternoon, because this time the cucumber surface humidity is small, the wound healing after bagging fast, is not conducive to disease. When the humidity in the rainy weather is high, it is not suitable for bagging. Second, before bagging, pay attention to spraying the disease-resistant cucumber before bagging, apply chlorothalonil and other protective fungicides to spray the plants all over again, with particular emphasis on spraying the body and then bagging. Note that the bagging must wait for the liquid on the body to dry before it can be carried out. First, the humidity in the bag is large enough to prevent the disease; second, the anti-drug liquid quits, which can easily lead to injury. Then pay attention to the bagging to avoid scratching the body to be careful operation, gentle action, so as not to cause a large wound on the body of the bacterium, open the door for the infection of the bacteria. In addition, the cucumber must be picked up before leaving the bag. In order to avoid the residual flowers infected by bacteria, and then infect cucumber. According to the actual situation of the master teacher, the experts suggested that the bagging cucumbers that have already suffered from disease should be removed as soon as possible and buried deep outside the shed. At the same time, the DT with 1500 times agricultural streptomycin mixed with 500 times liquid should be sprayed through the entire shed.
