PROBLEM TO BE SOLVED: To provide means to a farm by which the farm can be released from threats compelling the farm to abandon an agriculture using a vinyl house and put it in a dormant state because of threats such as an exposure to a heavy snow particularly in a snowy region, or an attack from strong wind such as a typhoon in a windy region.SOLUTION: Many eyelet holes are arranged on a vinyl sheet. The holes are placed over other holes and they are tied with a connection string in order to enhance the yield strength of the vinyl sheet. On the other hand, a resin sheet is placed over another resin plate sandwiching inside thin iron rods welded in a net-shape, and they are fixed with adhesion bond.【課題】特に雪国では大雪に晒され、強風地域では、台風などの強風が襲いかかり、ビニール・ハウスを用いる温室栽培農業が休眠状態でやむなく放置せざるを得ない状況にある農家をこうした脅威から解放する手段を提供する。【解決手段】ビニールに多数の鳩目穴を開け、穴同志を重ねて連結紐で結んでビニールの耐力を高める。一方、合成樹脂の板を重ねてその内部に細い鉄棒を網状に溶接した状態で挟み込み接着ボンドで固定する。【選択図】図１
