TYPES OF NETS

 

Shade Net House : It is primarily constructed to protect plants from highly intense solar radiation. The structure is made of wood, stone, bamboo or GI pipes. When wood or bamboo are used, the poles are treated with turpentine and tar on one side before inserting them in the ground. Cladding material used on the top and sides of the structure is generally a shade net. The shade nets are available in different colours with different percentages of shade factor. Suitability of colour and shade factor is location and season-specific. Generally, shade nets are used for hardening of fruit orchard planting material raised under greenhouses.

Walk-in tunnel :It is a temporary structure made by using GI pipes or bamboo, and is covered with different cladding material depending upon the season in which the cultivation is proposed. Walk-in tunnels are used for off-season cultivation of vegetables and flower seedlings. They give an advantage of better prices of the off-season produce, giving more profit per unit area. Optimum size of the walking tunnel is 60–75 sq m, with 2–2.5 m width and up to 30 m length with a 2–2.5 m central height. Overall, the height is enough for the worker to walk comfortably during operation. Advantages 1. The worker can easily walk-in to take care of the crop. 2. The cultivators get higher returns from off-season cultivation of vegetables and raising of flower seedlings. 3. These are temporary and low-cost structures, which can be fabricated by the cultivators themselves at the village level with the help of rural artisans. Net Houses Depending upon the cladding (covering) material used, the net houses may be classified as insect-proof net houses and shade net houses.
