Closely planted chestnut shaping and pruning

The plastic shape is low stem and low crown open heart shape, the stem height is 30cm and 40cm, the tree height is not more than 4m, the main branch is 2mm, and the maximum number is not more than 4. there are 1-2 lateral branches or direct bearing branches on each main branch, and the angle of the main branch is 50-60 degrees. Pruning moderately truncated main branches, lateral branches and other backbone branches of elongated branches according to the variety, tree potential, tree age to determine the degree of short truncation. There is no space for the thinning of the developing branches, and the spatial developing branches are cut short and cultured into the fruiting branch group, thinning as little as possible. If there are more fruiting mother branches on the same branch, they will truncate or remove the strongest fruiting mother branches at the end, leave the stout fruiting mother branches in the middle, and remove the weak fruiting mother branches in the lower part. The juxtaposition of 3-4 strong branches, forming three-strand fork and four-strand fork, were treated by the way of thinning 1 slow 2 or 1 cut 1 slow 2. Remove thin and weak, disease and insect pests, overlap, over-dense branches and chicken claw code, fishbone code and some strong terminal branches. Retract the long, weak fruiting branch group to the lower branch. The dense planting high-yield garden can leave 10 12 fruiting mother branches per square meter of crown projection area, and 6 million 8 fruiting mother branches per square meter in hilly and mountainous areas with poor site conditions.
