Various Collapsible Frames of Solar Warmer-cum-nursery Plant Protector

Nursery raising in Himalayan region is a very difficult proposition due to inclement weather conditions and higher chill factor. With a view to raise healthy plants for in time supply, a quick portable type solar warmer-cum-nursery plant protector (SWNPP) has been developed. Heat loss estimates and the extent of total solar impact at two different locations in the Himalayas have been worked out. Using commonly available materials a local village carpenter can very easily fabricate SWNPP unit. It can be installed by any unskilled worker quickly on the nursery bed as and when needed. And, therefore, these units have got heavy potential to be used in the temperature as well sub-tropical zones of Himalayas experiencing sudden weather changes and where full-scale greenhouses for various reasons are generally not working out feasible.
