Matters needing attention in autumn cutting of cherry trees

Cherry in China's market demand is very large, welcomed by many people, has a more extensive planting area. When planting cherry trees, we need to do a good job of pruning according to the changes of seasons. Especially in autumn, autumn shearing has a great impact on the growth of cherry trees in the second year, and there are many places that need our attention. So what are the matters needing attention for autumn cutting of cherry trees? Let's take a look at it.

1. Smooth cut

When we prune cherry trees, we must make sure that the cut of the branches is smooth enough. In general, it is necessary to maintain a 45-degree surface with the sprouts. It should be cut down from the opposite side of the bud, while the trimmed bevel and the tip of the cut bud should be kept in a horizontal position. In this way, the wound surface can be reduced as much as possible, the healing speed can be improved, and the growth rate can be maintained after bud germination. Finally, for the cut left by thinning branches, it should be cut off at the branch point, and no residual piles can be retained.

2. Division work

When pruning cherry trees in autumn, we should adjust the pruning methods according to the shape and age of cherry trees. For example, when we trim the branches and trunks, we should mainly use the partial operation method. First of all, we should be about 20cm above the trimming saw. Make a cut from the bottom of the branch, keeping the depth about the same as that of the branch. Then cut off the branch from the upper end, retain the residual pile, and finally cut off the residual pile from the previous saw. In this way, the split phenomenon of branches can be effectively prevented.

3. The saw blade is flat

When trimming, we should not only keep a smooth cut, but also make sure that the saw is smooth enough. Because after pruning, it is inevitable to encounter some rainy days and other bad weather. If the saw blade is not smooth enough, it is easy to rot after being caught in the rain, and it is also easy to be infected by germs, causing a variety of diseases and insect pests. So after sawing the cherry tree, we should use copper sulfate solution to disinfect the saw in time. Then smear an appropriate amount of protective wax and other protective agents on the saw edge. It can not only prevent the saw from decay and dryness, but also improve the healing speed of the saw.

4. Pruning time

The autumn cutting time of cherry trees also needs us to pay more attention to. Generally speaking, the autumn cutting of cherry trees should be after September. Because at this time, the new shoots on the cherry trees basically stopped lengthening, and the growth was in a state of one and a half stops. Cherry trees do not respond much to pruning, but some green parts grow at the top of the shoots, consuming too much nutrients. Therefore, we should pay attention to cut it off in time to save nutrition. However, because each orchard has its own management habits, and the situation of each orchard is different, it is necessary to determine whether and when to prune according to the actual situation.
