The main points of the latest course on Summer Management techniques of Apple Orchard

Apple is very common in our life. Apple is very rich in nutrients and is favored by many people. Now apples are planted all over our country. When planting apples, we should adjust the management methods of apple trees reasonably according to the changes of seasons. Especially in summer, how should we manage the apple orchard in summer? The following editor brings you the key technical points of summer management of apple orchard. Let's have a look! .

1. Watering management

In summer, because the temperature is too high and water evaporates quickly, apple trees have a great demand for water in summer. Therefore, we must water in time, but we must pay attention to control the watering method, do not flood irrigation, otherwise it is easy to lead to apple trees to grow. And if the soil water content is too much, it will lead to lack of oxygen in the roots of apple trees, resulting in the death of capillaries. Therefore, when watering apple trees, we should give priority to a small amount of water and water a small amount of water. According to the weather changes and tree situation to control the amount of water, to ensure to meet the water needs of apple trees, but will not affect the normal growth.

2. Fertilization management

The demand for nutrition for the growth of apple trees is also relatively large. When planting, we should combine with watering to apply fertilizer. But also to control the amount of fertilizer, if too much fertilizer, too little water, then easy to survive, on the contrary, it is difficult for new shoots to grow into flowers. In fertilization, we must control the type of fertilizer and the amount of fertilizer, if the fertilizer is not appropriate, then the impact on apple trees is very great. For example, in the application of fruit fertilizer, if the use of high-nitrogen and high-potassium fertilizer and then flood irrigation, then the fruit tree flower bud differentiation home burning, the emergence of large and small fruit phenomenon. Not only will the output be affected, but the quality will also decline. Therefore, summer fertilization should be based on phosphorus and potassium fertilizer, combined with an appropriate amount of low nitrogen and trace elements.

3. Weeding management

In summer, fruit growers bag the fruit, but many fruit growers select ploughing and weeding the orchard after bagging. In fact, during the growth of the apple tree, the deep turning of the tree plate will affect the shallow absorption root of the fruit tree. As a result, it can not play its due role, and flower bud differentiation is blocked. And if the summer temperature is too high, the respiratory capacity of the roots and leaves will also be enhanced. The temperature of the grassy orchard is much lower than that of the clear-ploughed orchard. No-tillage should be the main method for weeding in the orchard in summer. When the weeds grow too high, they can be cut down and covered under the tree plate, which can be used as organic fertilizer.

4. Thinning management

Summer shearing is very important for the flower bud formation of apple trees. However, in summer, many fruit growers do not pay attention to control the object and cut the new shoots indiscriminately, which is intended to improve the light of the tree. In fact, it has a great impact on the root-crown balance of apple trees. It leads to sunburn of branches and leaves and sunburn of young fruits, which affects the flower bud differentiation of apple trees. When we cut in the summer, we should pay attention to properly remove some overgrown branches and virtual branches, and twist the shoots properly to break off the terminal buds and promote the germination of new buds.

The above is a brief introduction to the key points of summer management techniques in apple orchards. The summer management of apple orchards is very important, which is closely related to the yield and fruit quality. We must pay more attention to it. This is the end of today's introduction, this article is for reference only, I hope it can be helpful to everyone!
