The cold dew has already passed quietly. In the eyes of farmers' friends, the cold dew is not only an important period of autumn harvest, autumn, and autumn management, but also a key period for fruit tree management. Many fruit trees are the most important time for growth and development before and after the cold dew. The management at this time will directly affect the yield and quality of the fruit trees in the current year. How to manage the consequences before the cold dew?
1, citrus
(1) In the middle and late varieties, the pre-harvest fertilizer should be applied in time.
(2) Mid-late varieties erase late autumn shoots. Special early-maturing varieties are timely thinned out and thinly mined after harvesting.
(3) Grasp the prevention and control of pests such as red spider, rust tick, and whitefly, and control the fruit nocturnal moth in mountain orchard, and pay attention to the prevention and treatment of ulcer disease and anthrax.
(4) Harvesting early-maturing varieties and post-harvest fertilization.
2, Yang Mei
(1) Carry out the work of deep renovation of Yangmeiyuan according to local conditions. The deep turning depth is 30-40 cm, combined with the soil change, the turf and weeds are buried in the soil.
(2) Continue to prevent and control the moth and disease.
(3) Continue to pay attention to the typhoon. After the typhoon, the branches should be timely shredded, and the plants should be straightened and cultivated in the rhizosphere to restore the tree early.
(4) Do a good job in the new development of Yangmeiyuan's planning infrastructure. The garden should be convenient to transport, the soil layer is deep and fertile, and the soil is slightly acidic or neutral on the shady slope or semi-shady slope (north grade slope).

Preventing the leaves from being too early and inducing secondary flowering, affecting the amount and yield of the next year. Develop a winter pruning plan and a production plan for the coming year.
The above is the management point of the tree before the cold dew. Before the cold dew, the farmers should strengthen the management, timely prevent the impact on the fruit trees due to weather changes, pay attention to prevent the pests and diseases of fruit trees, and achieve the goal of high yield and high quantity.
