PROBLEM TO BE SOLVED: To provide a warming system for a plant green house which can save energy and which requires less energy for warming.SOLUTION: An inside coated body 104 is arranged in inside of an outside coated body 100. The inside coated body 104 is configured so that, a vertical surrounding space 108 is formed by left and right coated bodies each of which are arranged on each of left and right sides of a stem, and an upper coated body is horizontally arranged above the vertical surrounding space 108, thereby forming a lateral vine/leaf surrounding space 110 continuous to the vertical surrounding space 108 is formed, and forming an inside green house space whose cross section is a T-shape in view from a gable side 112. Warmed air warmed by a warming system is injected to a lower part of the vertical surrounding space 108 from an injection hole, then the warmed air becomes an ascending air current, then the ascending air current is divided into left and right air currents by the upper coated body, then the divided air currents are sucked from a suction hole provided on a tip part of the lateral vine/leaf surrounding space 110 by a suction action of blowing means. Since air whose temperature is relatively high and which is guided by the upper coated body is circulated and utilized, energy can be saved.SELECTED DRAWING: Figure 1【課題】暖房に要するエネルギーが少ない省エネルギー型の植物温室用暖房装置を提供する。【解決手段】外側被覆体１００の内部に内側被覆体１０４が配置される。内側被覆体１０４は、茎部の左右に配置された左右被覆体によって縦向包囲空間１０８が形成され、当該縦向包囲空間１０８の上方に上側被覆体を水平に配置することにより、縦向包囲空間１０８に連続する横向蔓葉包囲空間１１０が形成され、妻側１１２からみた断面がＴ型の内側温室空間が構成される。加熱装置によって加熱された空気が送風手段によって噴出口から縦向包囲空間１０８の下部へ噴出されて後、上昇気流となり、上側被覆体によって左右へ分けられた後、横向蔓葉包囲空間１１０の先端部に配置された吸入口から送風手段の吸入作用によって吸入される。上側被覆体によって案内される相対的に高温の空気が循環利用されるので、省エネルギー化することができる。【選択図】図１
