Matters needing attention for winter pruning of the latest apple trees

Apple is a very common fruit in our daily life, and its nutritional value is very high. Therefore, the planting area of apples in our country is also very large, and when planting apples, we need to do a good job of management. Especially in winter, we should focus on pruning. However, there are a lot of precautions when pruning in winter. So what are the specific points for attention in winter pruning of apple trees? Let's have a look!

1. Make a good pruning plan

When cutting apple trees in winter, we need to make a special pruning plan according to the actual situation of the orchard. And even in the same orchard, there are major and secondary pruning contradictions. Therefore, when we formulate the construction plan, we should proceed according to the current situation of the orchard and the main problems. If there is not a reasonable construction plan, it may be counterproductive. In the formulation of pruning plan, it is necessary to combine various elements such as variety, tree age, tree shape, fruit, branch condition and so on.

2. Pruning tools

When cutting in winter, trimming tools also need our attention. In order to save money, many fruit growers will buy some very cheap pruning tools. Whether it is a scissors or a saw, if the quality is too poor, it is not only very difficult to trim, but also easy to cause the saw blade to bend, and the saw blade is also easy to be rough and uneven, making it difficult to heal. Therefore, we should ensure the quality of pruning tools, avoid skin tearing, improve the smoothness of the saw blade, speed up wound healing, and avoid some other problems.

3. Wound protective agent

When apple trees are cut in winter, the cuts and saws produced by them need to be protected. If it is not treated in time, the wound will dry for more than half a day and begin to crack in a day or so. And in the future, if you encounter wind and rain, then there will be mildew, drying up and other bad phenomena. Therefore, after we do the pruning work according to the standardized operation, we should apply the wound protective agent in time. If the wound is more than one centimeter, it is necessary to apply it evenly, and then stick a clean plastic sheet. under normal circumstances, the wound within two centimeters can heal in the same year.

4. Disinfection in time

In recent years, the virus in apple trees has spread very fast, such as mosaic disease, mosaic disease and so on. It can harm the whole orchard tree in just a few years, resulting in a serious decline in the yield and quality of apples. Pruning tools are an important factor in the spread of the virus, so we must pay more attention to it. First of all, we should mark the trees with viral diseases and prune them to the end. When pruning normal trees, we should first disinfect the pruning tools, and disinfectants can use fire alkali, disodium phosphate and so on to avoid spreading bacteria.
