Abstract

A polytunnel structure (10) is described comprising a plurality of cover support members (16) supported upon respective pairs of legs (12), a cover member (18) supported by the cover support members (16), an edge of the cover member (18) being secured to a rotatable beam (20), and an anchor rope (22), strap or the like extending over the cover member (18) to anchor the cover member (18) in position, wherein the cover support members (16) are each shaped to define a step (26) between a first section (28) and a second section (30), wherein when the rotatable beam (20) is supported upon the second section (30), the anchor rope (22), strap or the like provides a reduced resistance to movement thereof.

Description

technical field [0001] The present invention relates to a plastic greenhouse structure for crop cultivation to provide a controlled environment in which plants, trees or the like can grow. Background technique [0002] Where soft fruit crops and the like are grown on a commercial scale, it is increasingly common for the crops to be grown in plastic greenhouse structures and the like. The advantage of this is that the growing environment can be controlled, at least to some extent. For example, when planting crops in a plastic greenhouse structure, the temperature, humidity, etc. can be adjusted, so it is more suitable for crop growth. In this way, the period in which crops are harvested can be extended and crop yields can be increased. In addition, plastic greenhouse structures can protect the plants growing therein from damage such as high winds, heavy rain, insects or other wildlife. Therefore, using this structure can improve the efficiency of fruit production. [0003...
