In the maintenance and management of the lawn for one year, maintenance and management in the winter is often the most likely to be overlooked by managers. Negligence in winter conservation and management often leads to different degrees of frost damage and drought death on lawns, and low green return rates and late returning green time in the coming year. , so conservation managers in winter should also give enough attention. The author believes that winter maintenance management should start from the following aspects: Irrigation: Every year in the northern regions, lawns of varying degrees are dying due to lack of water in winter. Therefore, managers must pay attention to irrigation in winter. The lawn must be well-frozen before entering the winter, but it is important to keep a good grasp of the time and amount of frozen water. The frozen water should be carried out when the surface has just frozen, and it is frozen at night. It is better to pot frozen water at noon during the day. The amount of irrigation should be large enough to fully wet the soil layer, suitable for flood irrigation, but to prevent the occurrence of "ice cover." If the entire winter is in a warm winter state, it is necessary to determine whether or not to fill the frozen water according to the surface water holding capacity. Cold-proofing: For late-planting or late-planting lawns, winter should be properly covered for cold protection. The covering material can be plastic film, non-woven fabric (20 to 30 g/m2), straw or other materials, and care should be taken to fix the cold-proof material. Fire prevention: With the decrease of winter temperatures, the lawn begins to sleep and gradually enters the yellow period. Fires can easily occur at this time, especially in places with frequent human activities. In addition to doing a good job of pruning before winter and removing overly thick grass mats, we must regularly clean the litter on the lawn, and also send people to monitor. Anti-trouble: The winter lawn is in a dormant stage. The dormant lawn is in an extremely fragile state and is extremely vulnerable to external injuries. Therefore, winter maintenance management should prevent pedestrians from excessive trampling and rolling of the vehicle if the lawn is to be grounded at this time. Part of the worn out will cause the underground part to suffer freezing injury, which will affect the return rate of greening in the coming year. Greenening: Greenening is a measure of coloring a yellow lawn with pigments extracted from plants. In the winter in the northern regions, the lawns are in a state of browning. If the turf green period needs to be extended in some important areas or scenic spots, the turf can be greened to achieve the “evergreen†effect of the northern lawn all year round. The best time to choose the time is about two weeks after the last pruning of the lawn (about mid-November). At this time, the lawn is not yet brown, the effect of adding green coloration is good and the material is saved, and the “evergreen†effect can be achieved and the cost can be reduced. . Increase the concentration of green should not be too large, generally in order to achieve the normal growth of the turf color prevail, the concentration is too large a waste of green agent, the sensory effect is poor, so before the increase in green must first adjust the appropriate concentration can be large The progress of the area. Mechanical maintenance: Winter is the best time for maintenance and repair of garden machinery. It can be carried out throughout the season. Before winter storage of garden machinery, the equipment shall be sent to the designated maintenance department for inspection and maintenance or reference to the maintenance manual for maintenance. After maintenance, the equipment shall be stored in a dry environment. The spark plug connection shall be disconnected and the gasoline shall be completely placed. If the gasoline is parked for too long, there will be a gel-like substance that will clog the carburetor, and the oil will automatically condense into a gel when parked for a long time. And rinse the machine with water and dry it.

In 1892, French missionary father Tian Daneng preached in Dali, Yunnan Province, China. In order to drink coffee, he taught local villagers to grow and drink coffee. Up to now, coffee has been planted in Yunnan Province of China for more than 100 years, with an area of 120000 mu. Most of the varieties planted in Yunnan are ccatimor, with an altitude of 1000-1500m, The coffee produced in Yunnan has a balanced taste, rich nut and citrus flavor, some of which are very sweet, with obvious taste of chocolate, toffee and maple sugar. It is one of the high-quality coffee producing areas. Our coffee is produced at the junction of Puer and Burma - the Myitkyina original jungle beans at 1500-1750, with a rich flavor, high aroma and high sweetness. The 2019 international coffee cup Masters Tournament (China finals) is sponsored by beans.
