A Detailed Guide to the Latest Management Points After Bagging Apples
Apples are a fruit that many people enjoy eating very much, rich in nutritional value, with relatively large market demand, and the market price is also relatively high. Therefore, the apple planting area is now growing larger and larger, and when planting apples, the bagging work is very important. So how should we manage apples after bagging? Below, the editor brings you the management points after bagging apples. Let's take a look together!.
1. Reasonable watering
During the period from after bagging apples to before removing the bags, we must do a good job of watering. Reasonable watering during this period can not only promote fruit expansion, but also avoid an increase in temperature inside the bags, which could cause sunburn on the apples after the bags are removed. Moreover, reasonable watering is also beneficial for regulating the climate in the orchard, increasing the temperature difference between day and night, increasing nighttime dew, and promoting apple fruit coloration. We should water appropriately about 3 days before removing the bags, and at other times mainly according to the soil drought conditions and the weather and other specific conditions. Do not water too much; it is enough to keep the soil moisture content at about 60%.
2. Remove bags at the right time
After bagging apples, we should remove the bags at the right time according to the development of the apple fruit. Generally, the bag removal work is carried out one month before fruit harvest, usually in September-October. When removing the bags, pay attention to the weather. It is best not to do it on a sunny day, to avoid the fruit being unable to adapt in time after bag removal, causing sunscald on the fruit and seriously affecting fruit quality. If it is unavoidable to remove the bags on a sunny day, then it should be done in the morning to ensure the fruit surface temperature is close to the orchard temperature, but note that it must not be done in the early morning or evening.
3. Leaf removal and fruit turning
After removing the bags, we should do a good job of leaf removal and fruit turning according to the coloration of the fruit. Apple fruit coloration mainly depends on direct light, and insufficient direct light will have a great impact on coloration. Therefore, after removing the bags, we should promptly remove the leaves that affect fruit coloration. Then turn the fruit toward the sunny side to provide sufficient direct light for fruit coloration and improve fruit quality. When turning the fruit, pay close attention to avoid fruit drop. The amount of leaf removal should be controlled at about 12%, and at most must not exceed 18%. Likewise, leaf removal work should not be carried out under strong sun on a sunny day, to avoid sunscald.
4. Spray foliar fertilizer
After bagging apples, because the temperature inside the bags is relatively high, the metabolism of calcium and other elements is relatively fast. However, calcium has relatively weak transport capacity in the tree body, so compared with fruit trees that are not bagged, calcium deficiency is more likely to occur. Therefore, after bagging, we must do a good job of spraying foliar fertilizer, otherwise the apple trees are very likely to develop bitter pit due to calcium deficiency. Moreover, after removing the bags, the fruit's demand for calcium will further increase, so after removing the bags, foliar fertilizer should also be sprayed about 3 times. For the foliar fertilizer, amino acid calcium fertilizer can be chosen, and potassium can also be appropriately supplemented to promote fruit coloration.
The above is a brief introduction to the management points after bagging apples. The management work after bagging apples is very important, affecting the fruit set rate and fruit quality, so everyone must pay close attention. That is all for today's introduction.
