-Interview with Wei Wenke, extension researcher of Guangxi Academy of Agricultural Sciences. Farmer friend: The cold weather in the past month has done great harm to all kinds of fruit trees in our region, and also affected the fruit production this year to varying degrees. So, what about now? Wei Wenke, an agricultural expert and extension researcher of Guangxi Academy of Agricultural Sciences, gave the following suggestions (Sound-Database-How to Prevent Frost and Cold of Fruit Trees-Wei Wenke 3 ` 00```).

(Overall thinking: "First, popularize the" three avoidance "technology and do a good job in cold and antifreeze of fruit trees. First, do a good job in the cold protection of fruits. Mature fruits should be harvested in time and put on the market. Immature fruits should be sprayed with antifreeze or bagged for cold protection before frost comes. The second is to do a good job in cold protection of trees, and apply foliar fertilizers such as potassium dihydrogen phosphate, high magnesium fertilizer, fenfenwei 1 and compound nucleotide to improve the cold resistance of fruit trees. Third, the trunk of adult woody fruit trees should be painted white in winter, the orchard should be watered to prevent frost on the eve of frost, and the crown should be sprayed with water to defrost in the morning of frost; Fourth, herbs and vines, such as pineapple and pitaya, can be covered with straw or film to prevent frost; Fifth, the "Three Avoidances" technology should be vigorously promoted for fruit trees susceptible to frost, such as bananas and pineapples planted in autumn, and double films should be used to cover them against cold and winter. Sixth, irrigate (sprinkle) water in time to prevent frost in areas where there is no rain or little rain for a long time.

Second, prepare materials and prepare for disaster relief and self-help. It is necessary to prepare a batch of necessary materials for disaster relief and self-help, such as agricultural film, chemical fertilizer, pesticide, seeds and seedlings, etc. Once the disaster comes, we should organize technical forces to go deep into the orchard to guide disaster prevention and relief, and guide farmers to prune, fertilize and prevent diseases after the disaster.

Third, strengthen technical training to ensure that all technical measures are put in place. Technical training should focus on the cold protection of fruit trees, carefully organize technical training, use radio and television technical lectures, organize technical cadres to go deep into orchard fields to carry out various on-site training, print and distribute technical materials, establish popular science walls and other forms, and carry out technical training at multiple levels to ensure that all technical measures for orchard winter management are put in place.
