A good variety of open watermelons must be protected against horses
Nowadays, it's time for the open market watermelon season, but when interviewed by reporters, many melon farmers reported that the watermelon vines have recently been jeopardized by a yellow bug, which has greatly affected the growth. Some plants have become harder, curly, and withered. Some plants even appeared to have fallen off, and they did not know how to prevent it. The reporter consulted with the expert advisory group of the newspaper and Zou Zhirong, an expert of fruits and vegetables at the Northwest Agriculture and Forestry University. According to Zou Zhirong's analysis, this insect should be a Hummer. If it is not prevented and treated early, it will seriously affect the growth of the plants and the quality of the fruits. At the same time, it may induce the occurrence of viral diseases and other diseases, resulting in a large area of ​​diseases and insect pests. Zou Zhirong said that the horses like warm, dry weather, and its optimum temperature is 23°C~30°C. Therefore, it is necessary to promptly remove field weeds and increase irrigation so as to adjust the microclimate in the field so that it is not conducive to the survival of thrips. Second, it is necessary to strengthen fertilizer and water management and promote robust growth of plants. Only plants that are growing well can effectively resist the hazards of thrips. At the same time, it should be noted that if there is a phenomenon of soil compaction, cultivators must be cultivated in time to promote the growth and development of roots and prevent wilting of plants. In addition, in the midst of the Shengfa period, yellow plates can be set in the field to trap and kill adult worms. This method is simple, environmentally friendly and has good results. Chemical control is currently more efficient, low toxicity, long-acting drug, available 10% imidacloprid WP 1500 times, or 3% acetamiprid EC 1500 times, of course, the effect of trichlorfon is also good. However, it is advisable to alternate the use of different types of agents so as not to produce drug resistance in thrips. At the same time, Zou Zhirong also pointed out that the management of pests and diseases in farmland should also be based on prevention. Therefore, we must do a good job of preventive measures for the next watermelon. First of all, when choosing the land, we should choose to keep away from weeds, continuous crops without melons, fertile soil, convenient irrigation and well-ventilated fields. Secondly, we must completely remove the weeds from the fields and the remaining leaves from the litter, and burn them centrally or deeply. At the same time, deep plowing is required before sowing, and the soil is disinfected with quicklime so as to play an ovicidal effect.
