Description

A trimming means for seedling planting

Technical Field

The utility model relates to a gardens technology field specifically is a trimming means for seedling planting.

Background

The fruit tree pruning is a technical measure for cutting off a part of the nutritive organs of the fruit tree to adjust the structure of the crown and renew the composition of branches, and aims to act on the expansion of the crown of the fruit tree along with the increase of the tree age and the excessive branches and leaves of the fruit tree, which inevitably cause the consequences of internal air outside, premature senility of the tree, serious big and small years, reduced fruit yield, reduced quality and the like. Timely and reasonable pruning can have the following functions of regulating the reasonable distribution of branches and leaves. On the basis of shaping, the density, distribution direction and leaf area coefficient of branches and leaves of each part of the tree crown are adjusted, so that the effective photosynthetic area of the tree crown reaches the maximum limit. Regulating growth and fruit bearing. So that the vegetative growth is normal but not excessive and overgrown; proper amount of flowers and fruits can be formed without weakening the tree vigor; meanwhile, the fruit tree can be prevented from aging in advance and can be renewed and rejuvenated in time. Regulating the proportion of the branch components. The growing period of the short branches is short, the consumption is less, the accumulation is early, but the leaves are less, and the total photosynthetic amount is low; the vegetative shoots have long growth period and much consumption, but the vegetative shoots also have much accumulation in the later period. The operation, distribution, consumption and accumulation of nutrient substances in the tree body in the annual growth period can be carried out according to the normal growth and reproduction rhythm by requiring corresponding and proper branch proportion for different tree species and tree ages. This can be achieved by trimming. Fourthly, the pruning can also balance the growth vigor among the group plants and among main branches on one plant, thereby achieving the yield balance and being convenient for management. In addition, pruning is also a means of coordinating the overground part with the root system.

The existing nursery stock trimming device is long in length setting of a handle generally for saving physical strength, and the handle is fixed in length and occupies a large space, so that the nursery stock trimming device is inconvenient to carry. To this end, it proposes
