How to manage longan trees in winter? What should I pay attention to? Also ask experienced netizens to help introduce the management points of longan trees in winter, which are listed in detail below for netizens' reference. Management points 1, watering and cold protection methods of young longan trees: dry winter weather, young trees due to shallow roots, weak resistance, need to be often drenched to keep moist; in addition, to cover the tree plate with weeds or other materials to reduce soil water evaporation, keep the tree disk moist, and reduce the number of times of watering, and can keep the roots free from cold. When the tree plate is covered, there must be a certain thickness (more than 15 cm) in order to have an effect. If the mulch is too little, the effect is poor. In areas with lower winter temperatures, special attention should be paid to the cold protection of young trees, and straw can be used to cover the trunk against cold. Management points 2, cleaning of longan orchard: winter is the best time to clean the orchard. Litter and weeds in the orchard can be transported to the outside of the orchard to be burned, and the trunk is brushed white with lime water, which can effectively reduce the source of overwintering diseases and insect pests. At the same time, the weeds in the orchard can be used to press the green soil or cover the tree plate. Management points 3. Longan orchard soil deep ploughing: orchard deep ploughing is generally carried out from mid-December to January. Soil improvement materials can be used locally and make full use of topsoil and weeds in the orchard. For the orchard with sticky soil, the soil improvement should not only increase the organic matter, but also loosen the soil and improve the air permeability of the soil. The material can choose high-efficiency and high-quality organic fertilizer plus loose soil matrix such as weeds, green manure or crop stalks and garbage; for the heavy sandy soil, the main purpose of soil improvement is to improve its ability of water and fertilizer conservation, and the material can choose high-efficiency and high-quality organic fertilizer plus pond mud or garbage. Specific operation methods of deep turning and soil improvement: generally, two symmetrical soil improvement holes are dug under the crown dripping line to fertilize. Take a tree with a crown diameter of 5 meters as an example, in an orchard with poor soil quality, two holes with a depth of 60 cm, a width of 40m and a width of 50cm can be dug, and 100Lv 150kg of soil improvement material can be applied. In the orchard with good soil quality, two shallow trenches with a depth of 40 cm, a width of 40 cm and a length of 1.5 mi 2 m can be dug, and 20 mi 30 kg of chicken manure can be applied. The amount of fertilizer application should also depend on the amount of fertilizer applied to promote autumn shoots. If organic fertilizer has been re-applied in autumn, winter fertilizer can be reduced appropriately. When putting fertilizer, you should put crude fertilizer on the bottom and concentrate fertilizer on the surface layer. If there are weeds, green manure or crop stalks, appropriate amount of lime should be added to promote decomposition.
