The rain and snow in the south are frozen and strengthened, and the crop damage should be scientifically prevented.
In the next three days, there will be small to medium snow (rain) or sleet in the southwestern region, Jiangnan, northern Xinjiang, central and eastern Gansu, Ningxia, and central Inner Mongolia. Among them, central Jiangxi, south central Hunan, northern Guizhou, northeast Yunnan Some areas of the area have moderate to heavy snow, and some areas of Guizhou's central and western parts, western Hunan and southern mountainous areas have freezing rain; there are light rains or showers in southern China. Today is the new round of cold air that brings rain and snow to the south. For the current freezing disaster in the south, the agricultural proposals are as follows:
1. At present, most of the rapeseed is in the slow growing period, and some are in the stage of buds. Before the rain (snow) freezing weather comes, straw, chaff or other crop straw can be used to keep warm between the rape rows to reduce the direct invasion of the cold wind. Spraying the phosphate fertilizer on the leaves of rapeseed to enhance the cold resistance and effectively prevent the leaves from being frozen. After the rain (snow) freezing weather, the low-lying rapeseed land should be cleaned and drained in time, drained and ventilated to prevent waterlogging and root damage, and improve cold resistance.
2, open field vegetables should clear the ditch drainage, the focus is to prevent freezing and warmth, dredge the compartment ditch, side ditch, waist ditch, remove stagnant water, enhance the breathability of the car face, increase the ground temperature; areas with conditions can be covered. The greenhouse vegetable should be strengthened in thermal insulation management. It can be used to buckle the small arch shed in the greenhouse, cover the film at night, or cover the film with straw curtains to keep warm and dehumidify. The bottom of the shed is made of plastic film as an apron to reduce the cold air at the bottom; block the gap and minimize the heat dissipation.
3, the orchard planting area should strengthen management, timely inspection of the orchard, when the temperature is lower than 2 ° C or frosty night, you can ignite sawdust, hay skin and other smoke in the orchard to keep warm; when the temperature is below 0 ° C, then Cover the canopy with straw or woven bag, or wrap the trunk with straw or plastic film to maintain the heat; if the fruit trees are found to be snowy, shake the snow in time to prevent the snow from breaking the trunk.
4, low temperature rain and snow frozen weather adversely affects the cold-tolerant flower seedlings, according to conditions can be moved into the room or covered to protect against the cold.
5, poultry and livestock sheds should pay attention to reinforcement, prevent wind and wind from falling into the shed; close the doors and windows to prevent the temperature in the livestock house from falling sharply during the cold air, but also pay attention to the proper ventilation in the livestock and poultry house to keep the animals The poultry house is fresh in air to prevent disease.
6. Due to the low temperature, the accumulation of ice or snow is slow, the phenomenon of road icing and wire icing continues. All localities should strengthen the management and coordination of the transportation department and agricultural products market, and ensure the normal supply and transportation of urban and rural residents' daily necessities. Safety.
Single Acting Hydraulic Cylinder
A single acting hydraulic cylinder is a type of hydraulic cylinder that uses hydraulic pressure to move in one direction only. It is designed to extend or retract under pressure from one side only, using a piston and rod assembly. The cylinder is usually mounted in a fixed position and the force is applied to the piston rod to move the load. Single acting hydraulic cylinders are commonly used in applications where the load needs to be raised or lowered, such as in dump trucks, construction equipment, and agricultural machinery. They are also used in industrial applications where precise control is required, such as in metalworking and material handling equipment.
