Problems solved by technology

In this case, for the use of electric heaters, due to the small amount of seedlings in the greenhouse in the early stage, and the idle ground and space in the shed within the shed, there is a lot of idle ground and space in the shed, and the heating of the idle space by the electric heater is wasteful.

Embodiment Construction

[0011] A variable-capacity plastic greenhouse electric heating shed, including a shed film 2 and a series of bow frames 1 standing in parallel, and 1 to a plurality of electric heaters 3, the shed film is dynamically draped in different positions according to the number of crop seedlings under the bow A number of bow frames cover different areas of the ground. When there are many seedlings, they are covered more, and when there are few seedlings, they are covered less. The electric heater is located on the longitudinal axis of the shed in the shed. The canopy film on the bow shed is extended after touching the ground on both sides and draped across the ground. The unused part of the shed film is stacked under the last covered bow frame and covered with opaque objects to reduce sunlight and delay aging.

Abstract

A small variable-capacity plastic electric-heating greenhouse in a greenhouse comprises a greenhouse film, parallelly standing arches and at least one electric heater. The greenhouse film covers the arches in the different number dynamically according to the number of seedlings under the arches and covers different areas of the ground. The greenhouse film covers more for more seedlings and less for fewer seedlings. The electric heaters are arranged on the longitudinal central axis of the small greenhouse. The area of the small greenhouse and output power of the electric heaters or the number of the electric heaters can be dynamically adjusted according to changes of actual seedling area during overwintering cultivation of crop seedlings, seedling required temperature can be satisfied while power can be saved.

Description

Technical field [0001] A variable -capable plastic greenhouse in the middle of the shed, involving the structure of plastic bow sheds, and more specifically a variable -capable plastic greenhouse in the middle shed. Background technique [0002] The temperature increase and thermal insulation of plant seedlings in winter are the key to restricting the quality of seedlings and success or failure. In order to improve the thermal insulation effect of plastic greenhouses, many farmers have added a small plastic greenhouse in the plastic greenhouse.Place electric heater in the shed for heating to increase the temperature of seedlings.For some crops that need to cut the seedlings in the shed, the amount of seedlings may be less at the beginning, and the area occupied in the shed is not large.The amount of seedlings will be more and more, and the area in the shed will become larger and larger.In this case, for the use of electric heaters, due to the small amount of seedlings in the gree...
