Can I water the fruit trees during the winter solstice?

You can water the fruit trees from winter to Sunday, and pour enough frozen water before freezing: it can increase the soil water content and seal the winter ground temperature, and watering is also one of the methods to prevent the cold and frost in late spring.

In winter, most fruit trees go into dormancy. Although the growth has stopped, the inside of the tree is still active. Therefore, the orchard should still be managed in winter, and the following work should be done well: cleaning the orchard: after the fruit is harvested, the dead branches, fallen leaves, rotten fruits and weeds left under the tree have become the wintering hiding places for many germs and pests. Therefore, during this period, it is necessary to combine pruning, organize personnel to thoroughly clean up dead branches, fallen leaves and pests, burn them centrally or compost them at high temperature in the orchard, and spray 30-50 times of Pomei 3-5 degree stone sulfur mixture or 45% crystal stone sulfur mixture on deciduous fruit trees such as peaches, apples, pears, grapes and plums.

Winter ploughing: In winter, there are many fruit tree pests overwintering in the soil, such as peach fruit borer and jujube fruit fly. Therefore, from the early winter to the next spring, the soil under the tree should be ploughed once (25-35 cm deep), so that the overwintering pests in the soil will freeze to death or be eaten by birds, or the surface pests or pests in the soil will be transferred to the deep soil to suffocate them.

Pruning in winter: After a year of growth, fruit trees are prone to tree disorder. In order to form a good crown structure, prolong the economic life, and achieve high quality and stable yield, deciduous fruit trees should be pruned from late June to1October 65438+1October in winter. Measures such as short cutting, branch thinning and bud thinning are mainly adopted. Prune young trees and generally lush trees lightly; Old trees and weak trees are cut down again. Prune young trees in winter and cultivate the crown into a reasonable tree type. The garden is closed by methods such as thinning, thinning and falling. Adjust the ventilation and light of tree groups and individuals. Scraping: Mature fruit trees have rough bark and many cracks, and the rough epidermis is upturned. These places are wintering places for pests and germs. Therefore, it can be eliminated by scraping the skin to reduce the population density and the initial source of infection of bacteria in the coming year. When scraping the skin, you should scrape off all the rough skin on the main branches and side branches, but not too deep, as long as you can scrape off the old warped skin and don't expose the wood. In case of fruit tree scars and disease scars, scrape with lime water after scraping. At the same time, the scraped bark should be burned in time.

Whitening: In winter, due to the sudden change of temperature, the trunks and branches of fruit trees are exposed to direct sunlight during the day, the temperature rises and the tree cells are active. At night, the temperature drops sharply, which makes the tree tissue freeze to death before it can adapt. This is what people usually call "sunburn". Whitening fruit trees can reflect sunlight during the day and reduce sunburn in winter. The part painted white is mainly the trunk, and the bifurcation and trunk of the main branch should be painted more. The specific preparation method is as follows: 0/0 ~/0/2 parts of quicklime/kloc-2, 2 parts of clay, 36 ~ 40 parts of water, 2 parts of original solution of stone sulfur mixture or 5 parts of original solution residue, and 2 parts of salt1~. Hydrate the quicklime with water first, filter out the residue, pour in the melted salt, then pour in the mixture of stone and sulfur and clay, and smear the trunk after stirring evenly.
