Planting fruit trees in winter solstice solar terms

With the arrival of the solar term in winter, many fruit trees have entered the growth dormancy period, but at this time, fruit farmers have not neglected the management of orchards, especially in the anti-freezing of fruit trees in winter. Then let me introduce you to the planting of fruit trees during the winter solstice.

When pruning fruit trees in winter solstice, the branches of diseases and pests, cross branches, drooping branches and long branches in the crown are mainly cut off. Then apply 0.5 kg of urea and 0.2 kg of potash fertilizer to each tree, and bury it around the root cap to a depth of about 20 cm. Then wash the trunk with lime water and cover the ground with a thin layer of straw or weeds.

Before the soil freezes, water the frozen water again. When digging circular ditches or radial ditches under the projection of fruit trees, generally, according to the size of the trees, 2 kg of organic fertilizer is applied per 1 kg of fruit. Conditional orchards can be cultivated first, and then covered with grass, with a thickness of about 6 cm, which can not only adjust soil temperature and humidity, but also increase soil nutrients.

The freezing time of fruit trees is mainly related to the environmental temperature in winter. Watering the fruit trees too early will delay the dormancy period and affect the fruit setting rate in the coming year. If it is poured too late, it is often difficult for water to seep down in a short time and gather on the soil surface, which is easy to cause freezing damage to fruit trees and must be carefully grasped.

Deeply ploughing frozen soil, when the soil seems to be frozen rather than frozen in winter, orchard ploughing 1 time can not only improve soil physical and chemical properties and prevent soil hardening, but also help to freeze overwintering pests, pupae, grass roots and grass seeds in the soil.
