The latest Frozen Tree Preservation method for Citrus planting

Citrus is a light-loving plant, but if the sun is too strong, it will grow poorly. The annual average temperature suitable for growth is above 15℃, the optimum growth temperature is 23℃ to 29℃, the growth is stopped above 35℃, and the citrus fruit trees suffering from severe freezing disaster shall be protected by tree protection measures:

soil raising

Cultivate soil to protect root neck. Cultivate soil standard to ensure that root system is not exposed and root neck is covered. At the same time, strengthen intertillage and loosening soil, increase fertilizer application, prevent waterlogging, drought and disease and insect pest control, restore tree vigor as soon as possible, and pay attention to preventing and controlling gum disease after freezing.

Branches painted white, bandaged

Trunk, main branches for the skeleton of the tree, vulnerable to cold damage, resulting in tree weakness, serious when the cortex cracking, the whole plant death. Whitening agent is usually made of lime 10 jin, sulfur powder 1 jin, salt 0.2 jin, a little edible oil and water 30~40 jin. The trunk is wrapped with straw or coated with mud. The anti-freezing effect is better. When wrapping, pay attention to pressing the grass tail with the grass head and tie it tightly. Do not freeze the accumulated water in the grass.

fumigation

Mainly to prevent thick frost after freezing, can reduce radiation heat dissipation, reduce frost. Fumigating materials can be locally sourced, such as weeds, branches and leaves, etc., 4~6 piles per mu. Frost generally appears in the early morning, should master the critical temperature of freezing before ignition smoke.

spray steam inhibitor

Heat preservation agent can form a layer of molecular film on leaf surface, inhibit water evaporation, reduce leaf cell water loss, and have anti-freezing effect.
