Latest Key Points of Summer Management Techniques for Apple Orchards
Apples are very common in our daily lives. Apples are very rich in nutrients and are favored by many people. Now apples are grown all over our country. When growing apples, we should reasonably adjust the management methods of apple trees according to the changes of the seasons. Especially in summer, so how should we manage apple orchards in summer? Below, the editor brings you the key points of summer management techniques for apple orchards. Let's take a look!
1. Watering management
In summer, because the temperature is too high and water evaporates quickly, apple trees have a very large demand for water in summer. Therefore, we must water in time, but we should pay attention to controlling the watering method well and must not use flood irrigation, otherwise it is easy to cause excessive vegetative growth of apple trees. Moreover, if the soil moisture content is too high, it will cause oxygen deficiency in the roots of apple trees and cause the death of fine roots. Therefore, when watering apple trees, we should mainly use small amounts of water and follow the principle of watering more frequently with small amounts. According to weather changes and tree vigor, control the watering amount well to ensure that the water demand of apple trees is met without affecting normal growth.
2. Fertilization management
Apple tree growth also has a relatively large demand for nutrients. When planting, we should combine fertilization with watering. But we should also control the amount of fertilizer well. If too much fertilizer is applied and there is too little water, then it is easy for the trees to survive; on the contrary, new shoots will grow but it will be difficult for them to form flower buds. When fertilizing, be sure to control the type and amount of fertilizer well. If fertilization is improper, the impact on apple trees will be very great. For example, when applying fruit-swelling fertilizer, if high-nitrogen and high-potassium fertilizer is used together with flood irrigation, then flower bud differentiation of the fruit trees will be affected, and the phenomenon of large and small fruits will appear. Not only will the yield be affected, but the quality will also decline as a result. Therefore, summer fertilization should mainly use phosphorus and potassium fertilizers, combined with an appropriate amount of low nitrogen and trace elements.
3. Weed control management
In summer, fruit growers will bag the fruits, but many fruit growers will carry out selective tillage and weeding in the orchard after bagging. In fact, during the growth period of apple trees, deep plowing of the tree plate will affect the shallow absorbing roots of the fruit trees. This prevents them from playing their proper role, and flower bud differentiation is blocked. Moreover, summer temperatures are too high, and the respiration capacity of roots and leaves will also be strengthened. The temperature in orchards with grass is far lower than in clean-cultivated orchards. In summer orchard weed control, no-till sod culture should be the main method. When the weeds grow too tall, they can be cut down and then covered under the tree plate, where they can serve as organic fertilizer.

Summer pruning is very critical for the flower bud formation of apple trees. However, many fruit growers do not pay attention to controlling the targets well in summer and prune new shoots indiscriminately. Their original intention is to improve the light conditions of the tree body, but in fact it has a great impact on the root-crown balance of apple trees. This causes branch and leaf sunburn, sunscald on young fruits, and affects the flower bud differentiation of apple trees. When doing summer pruning, we should pay attention to appropriately thinning some water sprouts and excessively vigorous branches, and appropriately twist shoots, remove terminal buds, and promote the sprouting of new buds.
The above is a brief introduction to the key points of summer management techniques for apple orchards. Summer management work in apple orchards is very important and is closely related to yield and fruit quality, so everyone must pay much attention to it. That is all for today's introduction.
