The latest course of fertilization techniques for fruit trees in winter

There are many fruit varieties suitable for planting in our country, no matter what fruit trees are planted, fertilization is very important when planting. When fertilizing the fruit trees, we should adjust the fertilization methods according to the changes of the seasons. Especially in winter, there are still many things we need to pay attention to when fertilizing fruit trees. So the editor today brings you the fertilization technology of winter fruit trees, let's have a look!

1. Fertilizer selection

Before applying fertilizer in winter, we must first choose the fertilizer. The fertilizers applied in winter are generally all kinds of compost, green manure and farm manure. This kind of fertilizer is organic fertilizer, and the nutrition of organic fertilizer is very rich. And if it is used continuously, it can improve the soil of the orchard. The application amount should be determined according to the variety of fruit trees. in general, the application amount of adult fruit trees is about each 25kg. Among them, it should be noted that organic fertilizer should be in a fully mature state. If it is not fully mature, it will lead to fertilizer damage to the fruit trees.

2. Fertilization time

When fertilizing in winter, the fertilization time is very important. Because the growth habits of each fruit tree are different, the growth rules of fruit trees in winter will also be different. We also need to determine the fertilization time according to the growth law of the roots of fruit trees. Usually, if the base fertilizer is applied in autumn, it should be done in September. In addition, it was carried out from October to November, and if the base fertilizer was not applied at these two time points, it should be applied in time when the soil gradually thawed in the following spring.

3. Fertilization method

In winter, the main method of fertilization is ditch application, which should be dug into the ground around the crown of the fruit tree, and the position of the ditch should be kept at about 80cm with the middle trunk of the tree, and then dig about 5 radial ditches to the outside. You can also dig an appropriate amount of strip trenches at the outer edge of the fruit tree crown, with a depth of about 30 cm and a width of about 40cm. When digging trenches, be careful not to hurt the roots of fruit trees. If you encounter a thick root, then you should never cut it off. After fertilization, the fertilizer should be fully mixed with the soil, and then covered with soil and watered.

4. Supplementary application of micro-fertilizer

Under normal circumstances, the requirements of fruit trees for micro-fertilizer are not very strict, but they are also indispensable. If fruit trees lack certain trace elements, then fruit trees are prone to all kinds of element deficiency. For example, if the lack of iron, then the leaves are easy to yellowing, lack of zinc, the leaves are thin and dim. Therefore, we should pay attention to the supplement of micro-fertilizer, which can be applied together with organic fertilizer. The corresponding supplement should be carried out according to the lack of fertilizer of fruit trees to ensure the overall growth and nutrition of fruit trees and promote the normal growth of fruit trees.
