摘要：
The invention relates to a removable plant protection system, comprising a wall module including an upwardly extending wall segment that is arranged for throwing a shadow on a soil area near the wall module when the sun reaches its highest orbit point and for allowing a sun beam on the soil area at a time period on the day when the elevation of the sun is relatively low.
