How to color the latest apple after picking the bag?

Apple is a very common fruit in our daily life, which has a very large planting area in our country. When growing apples, bagging is an indispensable work in order to ensure the quality and output of apples. And after bagging, we should also pay attention to take off the bag in time, but many people will find that the coloring of the apple is not very good. So how can the apple be painted quickly after picking off the bag? Let's take a look at it.

1. Autumn scissors

Apple after bagging, under normal circumstances, the time to take off the bag is usually in autumn. Therefore, after picking the bag for the apple, we should pay attention to do a good job of autumn cutting. The main purpose of autumn is to improve the permeability of the inner chamber of apple trees and increase the light for the fruit, because the effect of light on fruit coloring is very great. The main objects of autumn pruning are overgrown branches, competitive branches and some long fruit branches under the crown. Ensure that every branch, leaf and fruit of the apple tree can be evenly exposed to light, or you can open the gap by using hanging branches, which can also increase the light.

2. Picking leaves

After picking the bag, we also have to pick the leaves of the fruit trees, mainly to remove some leaves that will block the fruit from being exposed to light. At the beginning of the bag, remove the rosette leaves next to the fruit, and then remove about 8 cm of leaves near the fruit at the end of the bag picking work. When picking leaves, you should pay attention to it around nine o'clock in the morning. Can not be carried out at noon on a sunny day to avoid burns. First remove the leaves attached to the fruit for about a week, and then remove the light-blocking leaves, diseases and insect pests and old yellow leaves around the fruit. However, it is best to retain the functional leaves to avoid the decline of photosynthetic efficiency of fruit trees caused by picking too many leaves.

3. Turning fruit

The main purpose of turning fruit after picking leaves is to ensure that each fruit can receive light evenly. For the fruit, it is the key measure to ensure that the shade side can also get sufficient light and good coloring. About a week after picking the bag, the fruit was turned when the coloring rate of the fruit to the sunny side reached about 70%. When turning the fruit, rotate the fruit 90 degrees or 180 degrees. Change the negative side into the positive side to ensure that the negative side is also fully exposed to light. When turning the fruit, we should pay attention to the strength, not too hard, so as to avoid the fruit falling. The work of turning the fruit is best carried out twice, and if it cannot be fixed after turning the fruit, then it can be fixed with transparent tape.

4. Water and fertilizer management

We should do a good job of watering the apple before we pick the bag. Because after the bag is not watered, if it is too dry, then only small water drip irrigation. In many cases, the poor coloring of apples after picking bags is caused by flooding after picking bags, so we should pay more attention to it. Then it is necessary to control the amount of fertilizer application, especially the basic elements such as nitrogen, phosphorus and potassium. If these three elements are excessive, they are the main causes of poor fruit coloring, so when we apply fertilizer, we should strictly control the amount of fertilizer, especially potash fertilizer, and not apply potash fertilizer without restrictions because of the serious lack of potassium in the orchard.
