Summer is coming, the rain is constantly. For natural disasters such as thunderstorms and hail, there is currently no good way to prevent it. Although it cannot prevent the occurrence of thunderstorms and hail, it can actively learn the orchard management measures after thunderstorms and hail, so that the fruit trees can recover from the disaster as soon as possible and reduce losses. Clean up orchards and reduce pathogens First, timely clean up the hail, fallen leaves and fruit falling in the orchard. For orchards with silt and stagnant water after the disaster, the accumulated water should be drained in time to remove the mud and expose the dried branches; the second is the severely damaged orchard with broken branches and broken leaves, comprehensively clearing the ground leaves, falling fruits, and digging deep Buried, remove the fruitless fruit, retain some of the fruit of the small pit, and reduce the loss of the year. Spraying drugs in time to prevent diseases Spraying fungicides such as thiophanate-methyl, bactericidal, bactericidal, bactericidal, carbendazim, etc. every 10 to 15 days, and spraying 2 to 3 times to prevent the invasion of bacteria. Loose soil, roots and trees, thunderstorms, hail, weather, should be continuously tumbling 2 to 3 times, in order to disperse excess water in the soil, improve soil permeability, restore root physiological activities, and thus achieve roots and trees purpose. Topdressing and restoring, restoring vitality The first is foliar spray fertilizer to solve the problem of insufficient nutrient in the tree; the second is to apply balanced NPK compound fertilizer in the underground, 0.5~1 kg per plant. After the fruit trees are restored to life, the fertilization is mainly based on farmyard manure, and the appropriate fertilizer is applied. In the case of drought, combined with fertilization for irrigation. Apply medicine to protect the wound After the main tree, main branches and some of the larger side branches of the cortex are injured by hail, the smashed rotten skin should be cut off in time, and the agents such as rot and medicinal herbs should be applied to promote wound healing. For wounds with an area of ​​more than 1 cm 2 , while applying the medicine, plastic bags are also used to accelerate the healing of the wound. Pruning branches, reasonably staying After the disaster, the broken branches should be cut off in time. For the branches with high density, heavy weight and unrecoverable damage, the branches should be cut off from the base or intact, and more stubborn branches or branches should be left to avoid large wounds. After trimming, the cut should be sealed to prevent dry rot. Due to the more wounds in the tree, the leaf buds under the wound will germinate rapidly. The newly sprouted branches should be properly preserved according to the tree shape to make up the vacancies of the branches. Other sprouting trees that disturb the tree shape and the sprouts at the base of the tree are all eliminated. . Manage flowers and fruits, improve quality In the event of a disaster, the severely damaged fruit will be removed in time to save nutrients and restore the tree as soon as possible. Other late fruit trees make up the bag. The causal tree leaf is interrupted and broken, and some fruit bagging is broken. The fruit is directly exposed under the scorching sun, which is prone to sunburn. It should be supplemented with bags to improve fruit quality and reduce losses. Strengthen prevention and control, restore the tree Fruit trees are weak after the disaster, and their disease resistance is reduced. Pay special attention to spray protection. First of all, it is necessary to spray the orchard with bactericides such as thiophanate-methyl for 2 to 3 times in a timely manner; secondly, spray 5 to 7 waves of sulphur sulphur mixture before germination to the next year, and do a good job at different times. Pest and disease prediction and prevention work to ensure that the tree body is restored to a healthy state as soon as possible.

Disposable latex gloves are divided into the following three levels. One is the powdered disposable latex gloves that are mostly used in the food industry. It is necessary to add them in the production process to prevent the gloves from sticking together and to facilitate wearing. It is important to note that there are good and bad cornmeal. We use food grade corn flour, otherwise it is not good for the user and the person being served. The second is the powder-free disposable latex gloves that are mostly used in the electronics and medical industries, because they are powdered when they are just produced, and the powder-free latex gloves obtained after our processing - washing with water. Third, they are mostly used in the precision electronics and medical industries. The purifying disposable latex gloves are made of powder-free latex gloves that have been washed with clean water and washed with chlorine again, and the cleanliness reaches a thousand grades.
