Top-opening type multifunctional ecological greenhouse

Abstract

The invention relates to the field of greenhouses, in particular to a top-opening type multifunctional ecological greenhouse. The top-opening type multifunctional ecological greenhouse comprises a supporting structure, a layering structure, a buffer, a sterilizing structure, four thin films, an anti-insect net, four electric film rolling structures, three door leaves, a guiding structure and a spraying dripping pipe system. The layering structure and the spraying dripping pipe system are arranged inside the supporting structure, through the layering structure, traction is conducted on vine-climbing vegetable crops to realize vine climbing, and the spraying dripping pipe system is used for conducting spraying irrigation on vegetables. The film rolling structures are used in cooperation withthe guiding structure, in this way, greenhouse films are easily, stably and rapidly rolled and unrolled, ventilating and light transmitting of the greenhouse are easy, and then the temperature insidethe greenhouse is effectively regulated and controlled; after the top of the greenhouse is opened, rainwater leaching is easy; soil salinization in the greenhouse is reduced, and bases are laid for healthy growth of crops; meanwhile, internal supports of the supporting structure of the greenhouse form a rhomboid, in this way, the greenhouse is more stable, the capacity of resistance to wind reaches 12 level or higher, and the capacity of resistance to snow reaches 30 cm.

Description

technical field [0001] The invention relates to the field of greenhouses, in particular to a top-opening multifunctional ecological greenhouse. Background technique [0002] With the development of science and technology and the emphasis on national agricultural development, greenhouse planting has become an indispensable tool for agriculture. The greenhouse is a simple and practical protected cultivation facility. The greenhouse is easy to build, easy to use, and less investment. It is suitable for the cultivation of crops. , with the development of the plastics industry, greenhouses are widely used by countries all over the world. Use steel as a support frame, and cover the support with plastic film to form an arched shed for the cultivation of vegetables, which can advance or delay the supply, increase the output per unit area, and help prevent natural disasters, especially in the early spring and late autumn in the northern region. Fresh vegetables are available in low ...

AI Technical Summary

Problems solved by technology

[0005] (1) Traditional greenhouses are designed with circular steel pipes and arches. The strength and structure of the steel pipes are relatively small. In typhoon and rainy and snowy weather, it is easy to cause the greenhouses to be blown over by typhoons or crushed by snow, causing serious damage to agricultural production. Big loss; it also affects the service life of the greenhouse

[0006] (2) The traditional greenhouse uses convection on both sides to achieve ventilation, but the hot air has the characteristics of rising. In early summer or summer, the hot air will gather at the top of the greenhouse and cannot be dissipated, which will cause the temperature at the top of the greenhouse to be too high. When cultivating corn For tall stem crops and climbing crops such as pumpkins and gourds, the smallpox of corn is likely to reduce the pollen vitality due to high temperature, and the leaves, flowers and fruits of climbing crops are also easily burned due to the high temperature of the roof, resulting in Severe yield loss and reduced quality of agricultural products

[0007] (3) There is no buffer zone in the traditional greenhouse. On the one hand, it is not conducive to winter heat preservation, and at the same time, it is easy to bring plant viral diseases, bacterial disease pathogens and pests into the greenhouse, resulting in the spread and spread of plant diseases and insect pests.

[0008] (4) The top membrane of the traditional greenhouse cannot be opened, and its removal in summer is likely to cause damage to the membrane, which is time-consuming and labor-intensive. If it is not removed, the salt in the soil will rise to the soil surface through capillary phenomena, resulting in serious soil salinization, and it is also easy to Causes the accumulation of diseases and insect pests, which seriously affects the ecological environment of the soil

[0009] (5) Since the traditional greenhouse does not have a horizontal support mechanism, when planting pumpkins, gourds and other framed crops in the greenhouse, it is necessary to use materials such as bamboo poles and iron wires to provide support for the crops, but this not only requires input material costs, but also takes time. It is labor-intensive, which is not conducive to saving costs and increasing efficiency, and the cultivation landscape effect is also poor
