Applications of Shade house
It aids in the growth of flowering plants, foliage plants, medicinal plants, vegetables, and spices. Used in fruit and vegetable nurseries, as well as the propagation of forest species, and so on. Aids in the quality drying of a variety of agricultural products. It use to keep pests at bay. Wind, rain, hail, and frost are all examples of natural weather disturbances. Used in the production of graft saplings as well as the reduction of mortality during hot summer days. Tissue culture plantlets harden using this method.
Making Plans for a Shade Structure
The shade house structure should design with the sort of crop to be cultivate in mind, as well as locally available materials and climatic circumstances. Shade House Agri Farming in India should be possible to expand in the future.
Site selection for Shade Structure
A shade house should situate such that it has easy access to markets for inputs and the sale of its products. This structure should build away from buildings and trees, as well as pollution from industry and vehicles. There should be no drainage issues on the property. Electricity and high-quality water should be available. Wind breakers, on the other hand, may be place 30 metres away from the structure.
Guideline of Shade House
When it comes to shade house orientation, there are primarily two factors to consider. They are the shade house’s light intensity uniformity and wind direction. Multi-part structures shall be positione in the north-south direction to guarantee uniform light intensity. Single span structures can be orient either east-west or north-south.
Materials used in construction
A shade house make up of two main parts: the frame and the cladding material. The shade house frame design to guard against wind, rain, and crop weight while providing support for the cladding material. If anti-rust treatment applie at regular intervals, the shade house mild steel (ms) angle frame can last up to 20 to 25 years, whereas the bamboo construction can last up to 3 years. Depending on the climate, the agro shade net might endure anywhere from 3 to 5 years. Shade nets are available in a variety of colours and shade percentages, including 25%, 30%, 35 percent, 50 percent, 60 percent, 75 percent, and 90 percent.
Shade house frames are designed based on the demand and technical competence. In high-rainfall locations like Orissa, structural frames in the Quonset, gable, or gothic arch shape, or with slight modifications suitable to local conditions, are recommended.
Shade House Design and Construction
Precision Farming Development Centre, Orissa University of Agriculture and Technology, Bhubaneswar, has developed two types of shade house designs. Shade House Agri Farming in India. The main benefit of these shade homes is that they do not require any welding on the job site. Another benefit is that the foundation pillars will chose to safeguard the structures from termite infestation. These shade houses’ specifications listed below.
Making a Shade House of Type One
Type One : As a structural frame, this design uses ms angle (35mm x 35mm x 6mm) and bamboo. The ms angles use as foundation posts, with a grip at the bottom and a ‘U’ clip at the top for holding bamboo. Both the purlin and the roof structure make of bamboo. The shade house site level, and then the plan lay out.
Pits for foundation posts have been dug, and a portion of the pits have been filled with sand and compacted properly. The foundation posts are then bonded with cement concrete in three parallel rows, preserving perfect alignment. Bamboo sized to suitable dimensions is utilized as purlin, roof arch structure (hoops), and is tied properly after proper curing.
Nuts and bolts secure the prefabricated end frame and door frame to the structure. Then, on the roof, agro shade nets of 50 percent to 75 percent are installed, and nets of 30 percent are installed on the side frame. Shade net is also used to cover the end frames and door. Finally, brick masonry use to construct the mid-pavement and boundary ridge line.
This type of shade house building costs around Rs. 225/Sqm per unit. Below Fig lists the materials utilized in this style of shade house. [ इस प्रकार के शेड हाउस बिल्डिंग की लागत लगभग रु। 225/वर्गमीटर प्रति यूनिट। नीचे अंजीर में छाया घर की इस शैली में उपयोग की जाने वाली सामग्रियों को सूचीबद्ध किया गया है। ]
Making a Shade House of Type Two
For the foundation posts, purlins, end frame, and door of the shade house structure, this design uses ms angle (40mm x 40mm x 6mm). The ms flat use to support the cladding materials using hoops. The foundation posts design to be attach to the purlin and hoops via nuts and bolts. Similarly, the ms flat used as hoops has a purlin fixing provision.
As in the prior scenario, site leveling and plan layout complet. The foundation posts are cement concrete-fix to the pits and allowed to cure for seven days. Nuts and bolts use to secure the purlin, hoops, end frame, and door frame.
After that, the nets attach to the structure. Finally, brick masonry use to construct the mid-pavement and boundary ridge line. This form of shade house structure costs Rs. 500.00 per square metre. The materials use in this style of shade house depict in the illustration below.
