Protective cover based on nursery stock planting

Abstract

The invention discloses a protective cover based on nursery stock planting. The protective cover comprises a shell, a through groove is formed in the shell, a telescopic groove is formed in the top surface of the shell, a telescopic outer cover is arranged on the shell, an empty groove is formed in the telescopic outer cover, the bottom end of the telescopic outer cover is matched with the telescopic groove, and a pin shaft is fixedly arranged in the middle of the top surface of the telescopic outer cover; and a first gear is rotationally arranged on the top face of the telescopic outer coverthrough a pin shaft, a rotating handle is fixedly arranged at the edge of the outer side of the top face of the first gear, symmetrical telescopic assemblies are arranged at the two sides of the telescopic outer cover, and clamping blocks which are symmetrical in pairs are fixedly arranged at the two sides of the upper end of the telescopic outer cover. The through groove is formed in the shell, the telescopic groove is formed in the top surface of the shell, the telescopic outer cover is arranged on the shell, and the telescopic assemblies which are symmetrical to each other are arranged at the two sides of the telescopic outer cover, so that the device can protect and cultivate nursery stocks with different heights, the flexibility of the device is improved, and the device is convenientto popularize.

Description

technical field [0001] The invention relates to the technical field of seedling cultivation and protection, in particular to a protective cover based on seedling cultivation. Background technique [0002] The surface of the protective cover should be smooth without burrs and sharp edges and corners, and should not become a new source of danger, and the protective cover should not affect the line of sight. Seedlings are saplings with root system and seedling trunk. Before going out of the nursery, they are all called seedlings. The types of seedlings: seedlings, vegetative propagation seedlings, transplanted seedlings, bed seedlings, seedlings can also be classified according to trees and shrubs. Generally, there are more tree seedlings in the north and more shrubs in the south. This is mainly due to growth. Caused by the climate, common seedling infectious diseases include damping-off, blight, anthracnose, and leaf spot. These diseases occur quickly and infect each other, of...

AI Technical Summary

Problems solved by technology

[0003] Adding a protective cover to protect the seedlings during the cultivation process can greatly improve the survival rate of the seedlings. However, the existing protective cover for nursery stock cultivation cannot be adjusted in height, which makes the seedlings may be hindered by the protective cover during the elongation process, resulting in the appearance of the seedlings. In the case of bending, the bending of seedlings used as garden landscape will affect the sales of seedlings, and the problem that the height of the protective cover cannot be adjusted also reflects that the protective cover in the prior art has poor flexibility and is not easy to promote. Therefore, the invention A kind of protective cover based on seedling planting is necessary to solve the above problems
