Latest Technical Method Tutorial for Fertilizing Fruit Trees in Winter
In China, there are a great many fruit varieties suitable for cultivation. No matter what kind of fruit tree is grown, fertilization work is very important during cultivation. When fertilizing fruit trees, we must adjust the fertilization method according to seasonal changes. Especially in winter, there are many points we need to pay attention to when fertilizing fruit trees. So today, the editor brings you the fertilization techniques for fruit trees in winter. Let's take a look!
1. Fertilizer Selection
Before fertilizing in winter, we must first choose the fertilizer well. The fertilizers used for winter fertilization are generally based mainly on various composts, green manures and farmyard manures. These fertilizers are all organic fertilizers, and organic fertilizers are very rich in nutrients. Moreover, if used continuously, they can also improve the orchard soil. The application rate should be determined according to the variety of fruit trees planted. Under normal circumstances, the application rate for adult fruit trees is about 25kg per plant. One thing to note is that the organic fertilizer must be in a fully decomposed state. If it is not fully decomposed, it will cause fertilizer damage to the fruit trees.

When fertilizing in winter, the fertilization time is very important. Because the growth habits of each fruit tree differ, the growth patterns of fruit trees in winter will also differ. We also need to determine the fertilization time according to the growth patterns of the fruit tree roots. Usually, if base fertilizer is applied in autumn, it should be done in September. Apart from that, it is done in October-November. If base fertilizer has not been applied at either of these two time points, then when the soil gradually thaws in the following spring, it should be applied promptly.
3. Fertilization Method
The fertilization method in winter is generally based mainly on trench application. Trenches should be dug on the ground around the tree canopy of the fruit tree for application. The position of the trench should be kept about 80cm from the central trunk of the tree, and then about 5 radial trenches should be dug outward. Appropriate amounts of strip trenches can also be dug at the outer edge of the fruit tree canopy, with a depth of about 30 cm and a width of about 40cm. When digging trenches, be careful not to damage the fruit tree roots. If thick roots are encountered, they must never be cut off. After fertilizing, the fertilizer should be thoroughly mixed with the soil, then covered with soil and watered.
4. Supplementary Application of Micronutrient Fertilizers
Under normal circumstances, fruit trees do not have very strict requirements for micronutrient fertilizers, but they are also indispensable. If a fruit tree lacks a certain trace element, then the fruit tree is prone to various deficiency symptoms. For example, if it lacks iron, the leaves tend to turn yellow; if it lacks zinc, the leaves are thin and weak, dull and lusterless. Therefore, we should pay attention to doing a good job of supplementing micronutrient fertilizers, which can be applied together with organic fertilizers. Corresponding supplementation should be carried out according to the fertilizer deficiency situation of the fruit tree, so as to ensure comprehensive growth nutrition for the fruit tree and promote its normal growth.
The above is a brief introduction to the fertilization techniques for fruit trees in winter. That is all for today's introduction. This article is for reference only, and we hope it can be helpful to everyone!
