Plastic greenhouse for growing seedlings of crop seeds

Abstract

The invention relates to a plastic greenhouse for growing seedlings of crop seeds. The plastic greenhouse comprises a fixing device, a ventilation device and a protection device, wherein a lower end of the fixing device is installed on the ground, the ventilation device is installed on an outer wall of the fixing device, and the protection device is installed on a lower side of the ventilation device. The plastic greenhouse has a protective effect on the growing seedlings through the protection device, prevents insects or birds from entering the greenhouse and causing damage to the growing seedlings, fixes a lower end of a plastic film clamping mechanism by matching a gap between a clamping block and a limit block of the ventilating device, thereby realizing a function of freely adjustinga height of an opening according to the required size of ventilation, and realizes a function of ventilating a single part or as a whole by arranging multiple plastic film clamping mechanisms.

Description

technical field [0001] The invention relates to the field of plastic greenhouses, in particular to a plastic greenhouse for raising seedlings of crop seeds. Background technique [0002] Plastic greenhouse is a simple building with plastic film as the covering material, which can partially control the environmental conditions of plant growth. It is a kind of greenhouse and is mainly used for raising seedlings. [0003] Because the seedlings cultivated in plastic greenhouses need to be opened for ventilation, ventilation is conducive to the growth of seedlings, but the following problems generally exist in the process of ventilation in plastic greenhouses: [0004] (1) When the plastic greenhouse is opened for ventilation, insects or birds often fly into the greenhouse, causing damage or death to the seedlings cultivated in the plastic greenhouse; [0005] (2) The growth of seedlings cultivated in plastic greenhouses will also vary in growth. Some parts will start to grow, a...

AI Technical Summary

Problems solved by technology

[0004] (1) When the plastic greenhouse is opened for ventilation, insects or birds often fly into the greenhouse, causing damage or death to the seedlings cultivated in the plastic greenhouse;

[0005] (2) The growth of seedlings cultivated in plastic greenhouses will also vary in growth. Some parts will start to grow, and some parts will just germinate. If ventilation is carried out at the same time, the newly germinated seedlings will not be able to accept the external environment. cause death
