The invention discloses a high-yield shape
pruning method of green prickleyash. The high-yield shape
pruning method comprises the following steps of: for earsh, pinching and remaining the
trunk, leaving robust buds on the
trunk; and pinching again, remaining main branches and culturing side branches on the main branches, pinching so that side branches can grow up and robust bearing branches are evenly distributed on each secondary
main branch; for fruiting tree, after harvest of green prickleyash,
thinning out redundant boughs, and carefully
pruning branches in the crown so that the
branch groups are evenly distributed; short
cutting the bearing branches to the range of 3-6 cm and
cutting off excessively fruiting and aging bearing branches; remaining robust buds on each
branch and removing redundant buds; and removing the side branches at the base part of the
trunk; and for old tree, removing old branches and breeding new branches, and prolonging the life of the tree body and the fruiting life of the tree. The high-yield shape pruning method is characterized in that shape pruning is performed at earsh, fruiting and old stages of green prickleyash, respectively, so that the tree groups are appropriate in density, the branches are even in distribution, and the crown is good in ventilation and light
transmittance effects; besides, there are few
plant diseases and
insect pests; the yield is high; the economic service life of the green prickleyash tree is long; and fruiting can be brought forward; therefore, good quality, high yield, stable production, and low consumption are realized.
