Controllable heat-dissipation thermal-insulation oblique arched seedling raising greenhouse

Abstract

The invention discloses a controllable heat-dissipation thermal-insulation oblique arched seedling raising greenhouse. The seedling raising greenhouse comprises a greenhouse frame and an outer protective enclosure, the outer periphery of the greenhouse frame is provided with the outer protective enclosure, the outer side of the outer protective enclosure is provided with an external thermal insulation system, and a water supply system and a power distribution system are arranged in the greenhouse frame; a parabolically oblique arched support is adopted at the upper part of the greenhouse frame, and the upper part of the greenhouse frame is provided with a side skylight system installed at the side edge of the parabolically oblique arched support; an outer sun-shading system is arranged atthe upper part of the greenhouse frame; and switching of thermal insulation and ventilation is performed by the external thermal insulation system and the side skylight system by adopting an electricfilm rolling form. According to the invention, the seedling raising greenhouse is stable and firm in structure, large in space span and easy to operate, the lighting performance is good, the ventilation performance is good, the thermal insulation performance is high, the seedling raising environment microclimate is conveniently controlled, the seedling growth is effectively accelerated, the seedling quality is improved, the seedling raising period is shortened, the worker labor efficiency is improved, and the problems that a seedling raising greenhouse is hot and humid in the summer and the temperature is too low in the winter are effectively solved.

Description

technical field [0001] The invention belongs to the technical field of agricultural and forestry planting equipment, in particular to a controllable heat dissipation and heat preservation inclined arch seedling-raising greenhouse. Background technique [0002] With the transformation of agricultural and forestry seedling production from traditional agriculture to modern agriculture, seedling cultivation has gradually realized industrial intensification, technical standardization, and commercialization of seedling supply. Nursery greenhouses can change the growth environment of plants, create the best growth conditions for plants, and prevent the impact of external environment changes and harsh climates on plant growth. Seedling greenhouses mostly use films with good light transmission and drip-free performance, PC sheets or glass as covering materials, which can be used to cultivate plants in winter or other seasons that are not suitable for the growth of open-field plants. ...
