用于保护行栽作物免受霜冻和昆虫的覆盖系统。
专利摘要
一种经济、快速安装和拆卸的植物保护系统，可用于草莓等行栽作物，以防止霜冻、冰冻和昆虫。该系统包括沿作物行放置的一系列框架，每个框架的上部具有至少一个麻线接合环。通过将麻线拉入环的开口端，将麻线完全绕过环，并在环处保持麻线张力的同时继续到下一个框架，使麻线沿框架的上侧张紧。保护罩覆盖在框架和张紧的麻线上，并锚定在作物沟中。框架之间的麻线张力防止保护罩下垂并接触作物。
Original abstractA plant protection system which is economical, and quickly installed and removed and which can be used on row crops such as strawberries to protect against frost, freezing, and insects. The system includes a series of frames placed along a crop row wherein each frame has at least one twine engaging loop on the upper portion of the frame. Twine is tensioned along the upper sides of the frames by drawing the twine into an open end of the loop, looping the twine completely around the loop and proceeding to the next frame with the twine held in tension at the loop. A protective cover is draped over the frames and tensioned twine and anchored in the crop furrows. The tension of the twine between the frames prevents the cover from sagging and touching the crops.
