In order to mitigate the effects of the cold rain and snow weather on the current production of fruit trees, such as citrus, and to prevent the winter freeze, the hunan daily newspaper (all media journalists) has developed emergency management measures for fruit farmers。
Citrus cryogenics often occur at high altitude or in low-lying mountainous areas. Before freezing, windwalls such as large membranes or sunnets can be used on the northern edge of windfronts or orange plantations. Brushed trunks and large branches of the canopy with raw lime 1:7 in the middle of the day, with a proper amount of salt, evenly mixed, or restrained straw on the backbone to prevent freezing. Pre-frozen water is promoted, and 7 to 10 days before the onset of cool temperatures, water is poured into orchards. Covered with straw, straw, weed, leaves or plastic sheeting on orange groves. Increased application of fertilized organic fertilizers, combined with phosphorus fertilizer and high phosphorus compound fertilizers, and improved base fertility in orchards. Strengthen pest management, trim the dead branches of disease, and the application of fertilizers such as ethrin, 0. 3 per cent potassium phosphate and other trace elements to the leaves to increase the resistance of trees to cold. Prior to the onset of the freeze, the facilities sheds were inspected and reinforced to ensure that the entrance doors to the sheds were secure and that citrus was filled with water in a timely manner。
On 6 january, a demonstration base for citrus cultivation was set up in the village of tiandong town, dodo county, and the fruit farmers were picking up oval. Zhang ke-cing (hunan gallery)
During the snow and ice period, the snow or ice accumulated on the tree is twitched in time. A conditional orchard can be smoked in an orchard on the night when it is clear and the temperature may drop to below 4°c. Prior to extremely low temperatures or snowing, appropriate ways of heating the roofs could be used to induce the snow to melt in time and to remove the snow from the roofs。
The snow, ice blocks and ditches are cleared in a timely manner in the event of ice and snow weather, and water is drained to prevent long periods of water and ice. Timely removal of fractured branch drys requires protective agent for larger wounds; the choice is to cut the thaws and leaves in the middle of the day. The plowing of the pine soil around the plate after freezing breaks some of the roots and balances the ground and the ground of the tree. The re-emergence of tree bodies is supplemented by the application of two to three times of leaf-face fatting, such as thorin ester + carbamate + potassium phosphate; the freezing of severely hazardous trees increases condensation, and the application of many times less fertilized water, which is treated as larvae. The canopy cover is removed in a timely manner when the weather rises. When the temperature rises in february-march in the spring, it removes the tree cover, removes the ground from the tree and displays the marriage interface. At the same time, microbicides were sprayed 2 to 3 times throughout the garden to prevent outbreaks such as anthrax。
