Key points of Apple Management after bagging

Apple is a kind of fruit that many people like to eat very much, which is rich in nutritional value, the market demand is relatively large, and the market price is also relatively high. Therefore, now the planting area of apples is getting larger and larger, when growing apples, bagging is very important. So how do we manage it after the apple is bagged? The following editor brings you the key points of apple bagging management, let's take a look at it! .

1. Rational watering

We should do a good job of watering the apple between after bagging and before picking the bag. Reasonable watering during this period can not only promote the expansion of the fruit, but also avoid the increase of temperature in the bag, which leads to the sunburn of the apple after picking the bag. And reasonable watering is also beneficial to adjust the climate in the orchard, increase the temperature difference between day and night, increase night dew and promote the coloring of apple fruit. We should properly water the bag about 3 days before taking off the bag, and the rest of the time mainly depends on the specific conditions such as soil drought and weather. Watering should not be too much, and the water content of the soil should be kept at about 60%.

2. Take off the bag at the right time

After bagging the apple, we should pick the bag at the right time according to the development of the apple fruit. Bag picking is usually carried out one month before fruit harvest, usually from September to October. When picking bags, pay attention to the weather, it is best not to carry out in sunny days, to avoid picking bags, the fruit can not adapt in time, resulting in sunburn phenomenon, seriously affecting the quality of the fruit. If you have no choice but to pick the bag on a sunny day, it should be done in the morning to ensure that the temperature of the fruit surface is similar to that of the orchard, but not in the morning and evening.

3. Picking leaves and turning fruits

After picking the bag, we should do a good job of picking leaves and turning fruit according to the coloring of the fruit. The coloring of apple fruit mainly depends on direct light, and the lack of direct light will have a great impact on the coloring. Therefore, after picking the bag, we should remove the leaves that affect the coloring of the fruit in time. Then turn the fruit to the sunny side to provide sufficient direct light for fruit coloring and improve fruit quality. When turning the fruit, we should pay more attention to avoid the phenomenon of falling fruit. The amount of picking leaves should be controlled at about 12%, no more than 18% at most. Similarly, the work of picking leaves should not be carried out in sunny days to avoid sunburn.

4. Spraying foliar fertilizer

After bagging the apple, because the temperature in the bagging is relatively high, the metabolism speed of calcium and so on is faster. The transport capacity of calcium in trees is relatively weak, compared with fruit trees without bagging, calcium deficiency is more likely to occur. Therefore, we should do a good job in spraying foliar fertilizer after bagging, otherwise apple trees are very easy to cause acne disease due to lack of calcium. And after picking the bag, the demand for calcium in the fruit will further increase, so it is necessary to spray foliar fertilizer about 3 times after picking the bag. Foliar fertilizer can choose amino acid calcium fertilizer, and can also appropriately supplement potassium to promote fruit coloring.

The above is a brief introduction to the main points of Apple bagging management. The management of apple after bagging is very important, which affects the fruit setting rate and fruit quality, so we must pay more attention to it. That's all for today's introduction.
