Novel greenhouse

Abstract

The invention provides a novel greenhouse. The greenhouse comprises an arch frame, an greenhouse body and ground, wherein the arch frame comprises a main girder and a plurality of arch bars; the main girder is arranged along the length direction of the greenhouse; the arch rods are arranged along the width direction of the greenhouse at an equal distance; the arch frame is provided with a thin film which is provided with a film roller; a sunshade net is arranged above the thin film and is provided with a net roller; the greenhouse body comprises an air fan wall and three heat-preserving walls; a plurality of air fans are arranged on the air fan wall; a heat-preserving windproof shed is built at one side of the air fan wall; the heat-preserving walls comprise central plate layers; the upper and lower layers of the central plate layers are heat-preserving layers; underground water circulation pipelines are arranged under the ground; and a plurality of valves for controlling ground-heating water flow are arranged on the underground water circulation pipelines. The novel greenhouse provided by the invention strengthens heat-dissipation, ventilation and rainproof effects and can adjust light intensity at any time according to weather conditions and crop growth needs; and since each water circulation pipeline is controlled by a valve, ground temperature of part of the ground can be adjusted to meet needs of different plants.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a novel greenhouse. Background technique [0002] With the continuous development of agricultural planting technology, greenhouses have become an indispensable basic condition for today's agricultural production. Existing greenhouses usually have the following disadvantages: 1. Boilers are often used for heating in existing greenhouses. Coal-fired boilers will cause environmental pollution, and the cost of oil-fired boilers is too high; 2. In summer, the temperature can only be reduced by ventilation. The ventilation effect is poor, the ventilation is inconvenient, and the temperature in the greenhouse is difficult to control; 3. Due to seasonal reasons and different crop growth cycle requirements for light, the greenhouse needs an adjustable shading system, and the shading nets of the existing greenhouses usually use Electric structure, the cost is too high.
