Description

Seedling freeze-proof device

Technical Field

The utility model belongs to the technical field of seedling freezing prevention, and particularly relates to a seedling freezing prevention device.

Background

The tree seedlings are simply called nursery stocks, which are the general names of various fruit tree seedlings, arbor and shrub seedlings; the seedlings are seedlings with root systems and seedling stems, the seedlings are called before being out of nursery no matter the ages of the seedlings cultivated in the nursery, the temperature in winter is low, and the seedlings which pass winter are affected by frost damage, if corresponding measures are not timely taken, the growth of the seedlings in the next year can be affected. At present, the winter protection measures for the forest seedlings are usually that heat preservation belts are bound on tree seedling stems by workers, or the seedlings are entirely sleeved by covers such as films, so that the heat preservation effect on the seedlings is achieved, but the manual binding efficiency is extremely low, the heat preservation effect of the heat preservation belts is general, and the survival rate of the seedlings is reduced.

In order to solve the problems, the Chinese patent application number 202220758068 discloses an anti-freezing and damage-preventing device for tree seedlings for forest cultivation, which is characterized in that the device is formed by mutually matching an arc-shaped heat-insulating film, a conical film, a zipper, a groove, a connecting belt, clamping rods, hooks, elastic ropes and fixing ropes, the arc-shaped heat-insulating films on two sides can be abutted and fixed by pulling the zippers on two sides, the fixing ropes are wound on the outer sides of the arc-shaped protective films and bound on a trunk at the same time, the upper ends of the fixing ropes are sealed, the elastic ropes are expanded from the upper ends of seedlings until the elastic ropes are sleeved in the groove, and then the lower ends of the conical film are buried in soil, so that the lower side sealing is realized, and a good heat-insulating effect is achieved.

But the device is when carrying out the arc fixed, needs to walk around the trunk of sapling respectively with both sides connecting band, and the rewinds is hung respectively on both sides couple, rotates the threaded rod again to drive both sides arc and remove to the middle part simultaneously, until both sides sealing strip card goes into in the both sides seal groove, just can accomplish the butt joint of both sides arc fixed, this installation needs to cooperate the operation step complicacy with the trunk of sapling, and needs to rotate the threaded rod, and installation effectiveness is low, is inconvenient for a large amount of reuse in the nursery.
