Key points in the Management of Apple trees in the Middle and late stage

Apple has a very high nutritional value, so it is welcomed by many people. Apple trees are widely distributed in China. When planting apple trees, we need to do a good job in management. Especially in the middle and later period of apple trees, the management of this time has a lot to do with the yield and quality of apples. So how to manage apple trees in the middle and later stages? Let's take a look at the key points of the management of apple trees in the middle and later period with the editor.

1. Timely harvest

In the middle and later stages of apple trees, timely harvest is very important. Timely harvest is not only the key to ensure the apple fruit, but also has a lot to do with the storability of the apple. Different varieties are harvested at different times. For example, Marshal varieties are usually harvested in early September every year. And if it is a golden crown suitable variety, then it should be carried out in mid-late September. Harvesting should start from the bottom and then go up. In addition, it should be done in the order from the outside to the inside. Mainly can not hurt the fruit branch, ensure the integrity of the fruit, retain the fruit stalk.

2. Soil, fertilizer and water management

We also have to do a good job of ploughing and loosening the soil in the middle and later stages of apple trees. Keep the soil transparent and soft, and improve a high quality soil environment for the root growth of apple trees. Then after harvesting the mid-ripe varieties, we should pay attention to the application of sufficient base fertilizer. Base fertilizer is generally based on rotten organic fertilizer, combined with an appropriate amount of special fertilizer for fruit trees. Generally speaking, the amount of fertilizer applied should account for about 65% of the amount of fertilizer applied in the whole year. When applying fertilizer, we should also pay attention to the way of applying fertilizer. Usually, the main fertilization methods are circular ditch fertilization and strip ditch fertilization.

Ring ditch fertilization is spread directly to the ground and then watered around the canopy of the apple tree. There is no need to dig ditches for fertilization in annular ditches, which can save a lot of manpower. If it is a strip ditch fertilization, it is necessary to dig a good fertilizer ditch, the effect is very good. In addition, we need to spray foliar fertilizer every half a month or so to enhance the photosynthesis of apple leaves and delay the time of falling leaves. Then it is necessary to control the water supply, do a good job of drainage and waterlogging prevention, promote the coloring of apple fruit and improve the quality.

3. Fruit management

Fruit management is mainly aimed at red Fuji and other late-maturing varieties and need to do a good job of drug management. It is necessary to do a good job in removing bags, picking leaves, turning fruits and so on. When removing the bag, you should first remove all the leaves near the fruit. Then the other shaded leaves were removed about 4 days later. After removing the bag for about 10 days, when the sunny side of the fruit is fully colored, turn it about 180 degrees to ensure that all parts of the fruit can fully see the light and improve the fruit coloring uniformity. In the work of picking leaves and turning fruits, it should be carried out in cloudy days, cloudy and other environments.
