Interlayer greenhouse-in-greenhouse heat preservation greenhouse

Abstract

The invention discloses an interlayer greenhouse-in-greenhouse heat preservation greenhouse, and relates to the field of agricultural building facilities. The greenhouse comprises an outer-layer greenhouse film, an inner-layer greenhouse film, a greenhouse framework, a heat preservation interlayer and an installing groove, wherein the installing groove is formed in the lower layer of the greenhouse framework, the outer-layer greenhouse film is connected to the upper layer of the greenhouse framework, the inner-layer greenhouse film is connected to the installing groove, and the outer-layer greenhouse film and the inner-layer greenhouse film are connected through the greenhouse framework to form the heat preservation interlayer. The interlayer greenhouse-in-greenhouse heat preservation greenhouse is provided with one or more heat preservation interlayers, the temperature inside the greenhouse can be increased, the temperature reduction speed can be reduced, and the heat preservation time is long.

Description

technical field [0001] The invention relates to a shed-within-shelf thermal insulation greenhouse, and relates to the field of agricultural building facilities. Background technique [0002] In the process of modern agricultural planting, in order to improve the planting efficiency of some crops, greenhouse planting technology was invented, which is a scientific planting method. [0003] The existing plastic greenhouses can utilize solar energy, have a certain heat preservation effect, and adjust the temperature and humidity in the shed within a certain range through the roll film. It is a non-heating, single-span arch roof structure greenhouse with plastic film as the covering material. The light transmittance is generally 60% to 75%. In order to ensure the basic balance of the average light throughout the day, the plane layout of the greenhouse is mostly in the form of extending from north to south. The existing technology of the greenhouse is easy to build, easy to use, a...

[0003] The existing plastic greenhouses can utilize solar energy, have a certain heat preservation effect, and adjust the temperature and humidity in the shed within a certain range through the roll film. It is a non-heating, single-span arch roof structure greenhouse with plastic film as the covering material. The light transmittance is generally 60% to 75%. In order to ensure the basic balance of the average light throughout the day, the plane layout of the greenhouse is mostly in the form of extending from north to south. The existing technology of the greenhouse is easy to build, easy to use, and less investment. It is a simple Protected Cultivation Facilities

The semi-arch round greenhouses are developing rapidly in Heilongjiang, Liaoning, Jilin, Shandong and other provinces. Walls are built on the north side and arches are set up on the south side. It is semi-arched and round. It is equivalent to the solar greenhouse in Beijing. It has good lighting, heat preservation, and wind resistance. It is easy to heat and can be used for seedling raising, seedling separation or direct cultivation, but the disadvantage of these greenhouses is that the indoor temperature cannot be maintained for too long, and the heat preservation time is average
