Ditching and drainage to prevent wet damage. There are more rain and rain in autumn, and the field humidity is high. However, citrus should not be soaked. If the soil moisture is high, the soil root system is easy to mold and rot, resulting in yellow leaves, falling leaves, and serious tree death. Therefore, in combination with fertilization, the ditch is opened in time to drain the moisture, and the tree belt is formed to facilitate future management. Timely clearing the orchard harms citrus disease sources and insect sources all overwinter in litter, weeds, and fruit drops. Therefore, in winter, the diseased branches, dry branches, fallen leaves, fallen fruits, and weeds should be thoroughly cleaned out of the orchard in time and burned and buried deeply. Pest control After the garden is cleared, starting from late November, use 180-300 times of 45% lime sulfur mixture for foliar spray every month, and spray 3 to 4 times a month, which can effectively control overwintering anthracnose and mites Plants, scale insects and other pests and diseases will reduce the number of pests and diseases, reduce the number of medications in the coming year, and improve production efficiency. Strengthening antifreeze and freezing damage will have a great impact on the citrus tree body and the next year’s yield. It can be prevented by whitening the trunk and mulching or (straw) on the tray (tree strip). Whitening the trunk can prevent freezing and prevent main stem diseases and insect pests. Stir with 72% water, 22% quicklime, 3% lime sulfur mixture and 3% salt, and then whiten it evenly, so that it does not flow down after coating and does not adhere to agglomerates.

It is necessary to apply basal fertilizer early. As a result, the tree can be fertilized one week after the fruit is picked. The fertilizer is applied early and the temperature is higher, which is beneficial to the decomposition of the fertilizer and the absorption of the tree body, and the fertilization is *********.
