Problems solved by technology

This further aggravates the disease of "old sheds"; the construction of steel pipe sheds has become the choice of greenhouse planting farmers in recent years after completing the original accumulation. Concentrated and large-scale companies also use steel pipes to build sheds, which can greatly extend the life of the greenhouse. Moreover, Exempt the defects of moso bamboo with many diseases and pests, but not only the investment cost of steel pipe is 8 to 10 times that of moso bamboo, but also the cost of anticorrosion of steel pipe is relatively high. The "hukang" effect is produced, causing the life of the plastic film to change from 2 years to half a year, shortening the life by 3 / 4
[0004] Apply CO 2 As a gas fertilizer, it can increase the yield of greenhouse crops by 30% to 120%. This technical measure has been confirmed by the scientific community 20 years ago and has been applied. However, this technology is rarely used in current greenhouses. Occasionally applications also lack CO 2 detection device, but cannot scientifically increase CO 2

Embodiment Construction

[0022] The main greenhouse D is composed of the north insulation wall A, the east insulation wall F, the west insulation wall G, the front pillar 9, and the overall outer covering layer B.

[0023] The north insulation wall A is composed of outer pillar 2, inner pillar 3, foldable inner curtain 12, foldable outer curtain 4, curtain moving shaft 1, block detachable thermal insulation foam board 13, and thermal insulation foam The board 13 is arranged from 30 to 50 cm below the ground level, and is connected to the north eaves of the greenhouse. The thermal insulation foam board 13 is designed to be movable. In winter, the foldable inner curtain 12 and the foldable outer curtain 4 are all put down, and heavy objects or soil are pressed to increase the heat preservation effect. To the late spring season, roll the moving shaft 1 of the roller blind, make the foldable inner curtain 12, the foldable outer curtain 4 roll to the height of about half, suitably remove the thermal insula...

Abstract

The present invention relates to a sun-light greenhouse. It includes mutually-connected north wall, east wall and west wall which are heat-insulating walls, in its south side several front supporting columns are set, on all the walls and front supporting column tops a ceiling frame is set, said ceiling frame is made into curved form, the outer side of said ceiling frame is covered with transparent heat-insulating film, and on the ground surface of the greenhouse an aquiculture pond is set.

Description

technical field [0001] The invention relates to the technical field of greenhouses for agricultural planting or cultivation. technical background [0002] The current greenhouses are generally two kinds of arched sheds. One is arched sheds made of moso bamboo or steel pipes, which have poor thermal insulation effect; This kind of shed has a good thermal insulation effect and sunlight utilization rate, and can grow cold-resistant vegetables for overwintering, but the ventilation performance in late spring is very poor, so it is not suitable for growing vegetables between late spring and early autumn. In addition, this kind of side slope Greenhouses also waste a lot of mellow soil resources. The common features of these greenhouses are: the structure of the greenhouse is backward and has not been optimized, most of the greenhouse materials are relatively primitive, and advanced materials have not yet been applied. [0003] In terms of structural materials, half of the curren...
