With the arrival of the winter solstice solar term of

, many fruit trees have entered the growth and dormancy period, but at this time, the management of orchards by fruit farmers has not been abandoned, especially in the antifreeze of fruit trees in winter. Then let the old yellow calendar introduce you to the fruit tree farming during the winter solstice.

冬至节气果树农事

during pruning of fruit trees in the winter solstice, the pest branches, Cross branches, drooping branches and bare branches in the tree crown are mainly cut off. Then, each plant can be applied with 0.5kg urea and 0.2kg potassium fertilizer. It is buried around the root crown with a depth of about 20cm, and then the trunk is painted with lime water, and the ground is covered with a thin layer of straw or weeds. Before the soil of

and

is frozen, the frozen water shall be poured. The circular ditch or radial ditch is dug under the projection of fruit trees. Generally, according to the size of the tree, 2kg organic fertilizer is applied for each 1kg of fruit. If conditions permit, orchards can be cultivated first, and then covered with grass on the tree tray. The thickness is generally about 6cm, which can not only adjust the soil temperature and humidity, but also increase the soil nutrients. The time of

and

fruit trees pouring and sealing frozen water is mainly related to the ambient temperature in winter. Watering too early will delay the fruit trees from entering the dormancy period and affect the fruit setting rate in the coming year. If it is poured too late, the ground freezing often makes it difficult for water to infiltrate in a short time and accumulate on the soil surface, which is very easy to cause freezing damage to fruit trees, so it must be handled carefully.

and

dig deep into the frozen soil. When the soil seems frozen but not frozen before and after the winter solstice, carry out a comprehensive ploughing of the orchard, which is not only conducive to improving the physical and chemical properties of the soil and preventing soil hardening, but also conducive to the freezing death of overwintering pests, pupae, grass roots and grass seeds in the soil.
