Description

Technical Field

[0001] The utility model relates to the technical field of soilless cultivation, in particular to a modular combined soilless cultivation greenhouse. Background Technique

[0002] Blueberries and blackberries are berry fruits that have been widely popular in recent years. Because they are rich in nutrients and have a unique taste, they have become healthy foods favored by consumers. Their demand not only continues to grow in the domestic market, but also occupies an important position in the international market. In order to meet the increasing market demand, growers have gradually adopted modern planting techniques to increase yields and fruit quality.

[0003] Soilless cultivation technology has gradually become an important choice for blueberry and blackberry cultivation due to its significant advantages such as water resource conservation and reduction of soil pollution. Soilless cultivation technology does not rely on traditional soil, but provides the necessary nutrients for plants through nutrient solutions or other alternative substrates. This method is particularly suitable for crops such as blueberries and blackberries that have high requirements for soil conditions, and can effectively control the growth environment, improve the growth rate of crops and fruit quality.

[0004] In order to implement soilless cultivation, growers usually use specially designed soilless cultivation greenhouses. These greenhouses mostly adopt a bracket structure fixed by welding or bolts. After being built, a heat preservation film is covered on the frame to ensure the stability of the internal environment. However, this fixed bracket design has certain limitations when expanding or reducing the planting scale:

[0005] 1. Inconvenient disassembly and assembly: Since the brackets of the greenhouse mostly adopt welding or bolt fixation, special tools and high labor intensity are required for disassembly, resulting in inconvenient operation. When growers need to adjust the planting area, they often face a cumbersome disassembly and assembly process.

[0006] 2. Lack of flexibility: Once the existing greenhouse structure is built, it is difficult to flexibly adjust according to changes in market demand or production scale, restricting the production flexibility of growers.

[0007] 3. Low space utilization efficiency: The fixed brackets limit the reuse of space to a certain extent. Once the planting scale is reduced, the redundant space cannot be effectively utilized, resulting in waste of resources.

[0008] Therefore, there is an urgent need for a new greenhouse design that can overcome the problems of inconvenient disassembly and assembly and lack of flexibility of existing soilless cultivation greenhouses, so as to adapt to changing planting requirements, improve the production efficiency and management convenience of blueberries and blackberries. In view of this, we propose a modular combined soilless cultivation greenhouse. Content of the Utility Model

[0009] The purpose of the utility model is to provide a modular combined soilless cultivation greenhouse to solve the problems raised in the above background technique.

[0010] To achieve the above object, the present utility model provides the following technical solutions:
