Chestnut tree pruning measures during fruit period
The winter pruning of chestnut trees in a fruiting period is an effective measure to prolong the period of full fruit and prevent the occurrence of large and small annual results. First, the period of trimming chestnut winter pruning, the period from the second half of the fall to the next half of the spring before the budding, that is, in mid-December to the second year of early February trim is appropriate, but hit the frozen weather To be suspended. Second, to pruning pruning, we must first cut branches and branches, overlapping branches, dry branches, cross branches, thin branches and other inferior branches cut off in order to improve the ventilation and light conditions within the crown, concentrated nutrition to make the shoots stout and full, For the branches of the apical shoots and their branches, it is advisable to leave short cuts of about 50 cm per year in order to trigger new shoots, increase the number of mother shoots, and control the rate of outward movement of the resulting parts. Third, the dense fruit branch for the past intensive results of the mother to sparse part; or a short part as a renewed branch. Before the canopy is connected, about 15 crowns per square meter can be reserved for the mother branch; after the canopy phase, about 12 mother branches should be retained. For the overgrowth, the mother branch should be appropriately shortened and promoted. A new branch is drawn from the lower part; the mother tree that has been aged has to be retracted so that the nutrition can be concentrated to trigger the new branch, and it can be cultivated as a result of the mother branch to continue the result. Fourth, according to local conditions in the pruning chestnut to see the soil and tree vigor. The soil is fertile, the soil is deep, and the strong tree vigor should not be heavy, otherwise it is the opposite. If winter pruning can be combined with fertilization, it can get twice the result with half the effort.
