Pear tree size winter cut different
After the pear tree enters the full fruit period, if there are too many fruits, or if the fertilizer and water are insufficient, it is easy to see the phenomenon of large and small results. Measures to prevent and overcome years of age, first, to strengthen the integrated management of fertilizer and water, and second, to adjust through pruning.
There are two kinds of pruning measures that are often used in production to adjust and overcome the annual pear fruit size results: First, in the big year, by controlling the number of flowers and fruits, leaving enough branches to obtain both the high yields of the year, but also To ensure a bumper harvest in the small year, the second is to keep flower buds as much as possible, and at the same time sparsely cut branches to control the number of flower buds so that the big year of the second year will not be too large.
In the pruning of the pear tree, it is necessary to sparsely cut flower buds and leave more preparations. Particular attention should be paid to the appropriate removal of excessive flower buds on short fruit bunches, and appropriate sparse cutting of fruiting results. For middle and long fruiting branches with flower buds, heads can be used to flower to form flower buds in the second year; for medium and long vegetative branches with strong middlings, they can be slowly placed and not cut to form flower buds. The results; for the weaker results of the branches can be used to weaken the weak, dense, strong retention of the shear rejuvenation, but the pruning should pay attention to retain the strong buds and parts of the higher headed branches; too much, too dense Auxiliary branches and large fruiting branches can also take advantage of the opportunity to spend more years of age, and appropriate thinning.
When pruning a young pear tree, it is necessary to leave more flower buds and leave fewer preparation branches in order to ensure the production of the young year. For robust and robust annual branches, 1-2 shoots with heavy shoots and short cuts can be retained, new shoots can be promoted, vegetative growth can be enhanced to reduce the number of large annual flowers, and flowering of the posterior branches and the former branches without flowers. , Can be sparsely cut on branches with flowers; branches on the branches without branches before and after, branches on the branches, can be shorter and shorter, with less delay, so as to reduce the amount of flowers in the second year and make it larger. The year will not be too large.
