Pruning the soil and picking the fruit is combined with pruning and clearing the garden, digging and fertilizing, selecting pond mud, river mud, field soil, etc., and cultivating the root and stem tree tray, 20-30 cm thick, and mulching the root to increase temperature and prevent freezing. Irrigation and heat preservation produce arid orchards, 10 to 20 days before the occurrence of low temperature freezing, where conditions permit, ditching is used for water filling, and canopy water is sprayed during the frost period to reduce freezing damage with water heat preservation. Before the chemical antifreeze low temperature comes, spray paclobutrazol on the canopy to make the leaves evaporate, reduce the heat loss of the tree and reduce the degree of frost damage. Before the soil mulch freezes, prepare the land through tillage and cover the garden with mulch to reduce soil temperature and protect the root system from frost damage.

Protect the tree body 1. Cover and protect the crown: whole young tree is wrapped in grass to prevent direct frostbite of branches and leaves. 2. Whitening the trunk: Use 5 kg of lime + 10 kg of water + 0.5 kg of salt + 0.1 kg of sulfur + fungicide to prepare a whitening agent. In December, the trunk will be whitened, and the dry will be 60 cm. The exposed branches and wounds are also To paint white, protect the main pole and branch.
Use firewood, chaff, sawdust, etc., to set up 4-6 smoked piles per acre to ignite the smoke before the cold wave or frost, so that it will form a smoke screen over the orange orchard. Radiation reduces frost, and at the same time, it can directly increase the temperature of the orange orchard and reduce freezing damage.
Before and after irrigating the root to prevent freezing and picking the fruit, use quick-acting fertilizer to water the root, combined with spraying 0.2%～0.3% potassium dihydrogen phosphate plus 0.5% urea mixture or chitin compound fertilizer to supplement nutrients, promote the rapid restoration of tree vigor and increase Nutrient accumulation, the tree grows sturdily, and enhances cold resistance. After fruit picking, organic fertilizer is applied to keep warm.
