This year Apple is about to set foot in the tree, and the price has fallen a lot compared to last year. Some fruit growers do not care about the management of the late fruit trees. This is obviously wrong. We must strengthen our confidence and persevere in the management of orchards. We must pay close attention to the administration of autumn basal fertilization, leaf protection, and disease prevention and control for the orchards that have already been harvested, so as to lay a good foundation for increasing apple yields next year. Spraying medicinal fertilizer leaves the fruit after harvesting and leaves are still in the growth period of 50 to 60 days. Failure to spray fertilizer on fruit trees in time will lead to premature leaf shedding, which will directly affect the process of flower bud differentiation, annual production, and tree production. Nutrient storage. Therefore, after harvesting fruit, it is necessary to spray 1 to 2 insecticides and fungicides, and add 0.5% to 1% urea solution or high-efficiency nutrient liquid fertilizer to ensure that the leaves are thick and bright, intact, and extend the effective functional period. The late growth of fruit trees and safe wintering provide more nutrients. Early basal fat root sticks “Four seasons of fertilization materials, basal fertilizer is the most important†There are more rains in autumn, and the orchards have good sensation. Early application and reuse of basal fertilizer are very important. The best fertilization time should be arranged from late September to mid-October. Per acre Shi quality rotten organic fertilizer 3000 to 4000 kg, or nitrogen, phosphorus, potassium compound fertilizer 60 to 80 kg. Basal fertilizer in autumn must be combined with organic, inorganic, biological, and trace fertilizers, base fertilizer and tree spray fertilizer, and fertilizer and water. The source of pest control and disease reduction is the period from harvesting to the end of autumn. It is during the overwintering period for various pests to lay eggs, reproductive offspring, and various spores for pathogens. After the fruit is harvested and after the fall, the whole garden is sprayed with insecticide, fungicide or 5 Baumedu lime sulfur can significantly reduce the base number of overwintering pests and diseases, and reduce the number and harm of pests and diseases in the next year. Carefully clear the park to optimize the environment, "the early winter garden after harvest is clear, less fruit and pests in the coming year," which is the experience of fruit farmers for many years from the production practice. After harvesting the fruits, we must seize every opportunity to clear the weeds, fallen leaves, rotten fruit, and fruit bags on the ground of the orchard. Cut off all kinds of "branches" on the tree and scrape the rot on the dried branches. To create a superior environment for apple production next year, the Qingyuan work cannot be a simple matter. It must be careful, thorough and thorough, and it should not leave corners.

According to ISO 17712 standard, the bolt seals shall be classified to High security grade then it is qualified to be called high security seals. Except the basic size requirement, the bolt seal has to reach the minimum requirements on the tensile test,impact test, bending test and shear test.
