(1) Shortcut: Shortcut is to cut off some branches. According to the shortcut, it can be divided into light short cut, medium short cut and heavy cut. Light cutting is to cut 1/3 branches, cut half branches and short cut 2/3 branches.
(2) Pruning: Pruning branches from the bottom.
(3) coring: in the growing season, the young end of the front end of the new shoot is cut off.
(4) Truncation: it is the truncation of perennial branches. Its function is to inhibit the advancement of tree potential and branch potential, and promote the rejuvenation of tree potential and branch.
(5) Scaling: Don't cut off the annual branches and let them grow. Its function is to relax branches and promote the differentiation of long buds.
Second, winter pruning
(1) Winter cutting period: Winter cutting is from defoliation in winter to germination in spring.
(2) Winter pruning principle: preserve the old and replenish the new, trim horizontally, cut off dense branches, and leave solid branches at sparse places; Cut off the bottom of the clearing, and the Crown Garden will be full of high yield.
(3) Winter pruning sequence: First prune the old branches, bypass the crown, prune the old branches and replace them with new branches. Remove the tillers from the roots of Lycium barbarum and grow branches. Take out the horizontal branches, weak branches, diseased branches, dead branches and old branches in the borehole. Cutting off the old and weak branches in the crown has little effect, which improves the ventilation and light transmission conditions in the tree and promotes the growth and development of the fruit.
The branches at the bottom of the crown 35 cm from the ground were cut off to facilitate soil management in the garden. For the first fruiting Lycium barbarum tree, it is mainly strong branches with short periphery, so as to solve the problem of uneven or insufficient crown strength and lateral branches and expand the crown of Lycium barbarum tree. Lycium barbarum is a kind of fruit tree branches that are pruned old and new on each crown. The thinning targets are old and weak branches, transverse branches, diseased branches, insect branches, fruit branches extending from the crown and over-dense branches. After pruning, the crown branches are smooth up and down, the density distribution is uniform, the canopy size is basically the same, and the ventilation and light transmission are good.
Third, summer pruning
(1) Remove the long branches from roots, trunks and trunks in time, usually with an interval of 8- 10 days.
(2) In the growing season, the relatively central branches in the early stage grow new canopies through short paths.
(3) Treatment of healthy branches: The robust branches of Lycium barbarum should be cut off many times at the initial stage of fruiting, so that the crown of the tree can expand rapidly and form a large number of fruit branches; In the full fruit period, when planting strong branches on the main branches of Lycium barbarum, measures such as dewatering, coring and cutting corners should be taken in time to increase fruit branches.
The above is how Bian Xiao shared the pruning of Lycium barbarum trees.
