What are the latest benefits of winter irrigation for fruit trees?
Fruit trees are very widely distributed throughout our country. Although there are many fruit varieties that can be grown in our country, the management methods are basically similar in winter. For example, whitewashing tree trunks, cold protection and warmth preservation, etc., and among them, winter irrigation is also an indispensable task for most fruit trees in winter. So what exactly are the benefits of winter irrigation for fruit trees? Today the editor will give you a brief introduction. Let's take a look together!
1. Improve the cold resistance of fruit trees
Carrying out winter irrigation on fruit trees in winter has the most obvious effect of improving the cold resistance of fruit trees. Because after winter irrigation, the ground temperature can increase somewhat, promoting root growth and protecting the roots. It can prevent fruit trees from suffering freeze damage during the dormant period, which would affect the normal growth of the fruit trees the following year. After improving the cold resistance of fruit trees, the trees can also reduce freeze damage, thereby increasing the safe overwintering rate of fruit trees and reducing some unnecessary losses.
2. Accelerate the decomposition of organic fertilizer
In winter, most fruit trees enter the dormant period, reducing their own nutrient consumption. After clearing the orchard, fruit growers also apply sufficient base fertilizer to ensure that the fruit trees have adequate nutrition. Base fertilizer is generally mainly organic fertilizer, and proper winter irrigation can accelerate the decomposition rate of organic fertilizer. The absorption of minerals by the roots will also be better, thereby improving the nutrient accumulation in the fruit tree body. It can also increase the water content in the soil, thereby improving the yield and fruit quality of the fruit trees the following year.
3. Prevent drought
After winter irrigation of fruit trees, water is stored in the soil, which can not only improve the cold resistance of the fruit trees, but also prevent drought phenomena such as winter drought and spring drought. Moreover, because winter irrigation increases soil humidity, it can prevent the contradiction between leaf water evaporation and water supply in winter. It avoids dry freezing of fruit trees caused by leaf evaporation and other reasons. In addition, if the water content of the soil increases, it is also very beneficial for the absorption of water and nutrients by the roots. It is precisely for this reason that the cold resistance and drought resistance of fruit trees are improved.
4. Avoid wind erosion
In winter, especially in deep winter, the environment is often relatively dry. Especially the soil, if there is strong wind and the soil is too dry, then the soil will be blown by the strong wind, causing the roots of fruit trees to be exposed and resulting in freeze damage, and for some young trees, lodging is also very likely to occur. Therefore, proper winter irrigation can keep the soil in a moist state. It can prevent the soil from being blown by strong winds due to being too dry, and can both preserve heat and moisture and play a role in wind prevention and freeze prevention.
