DESC:FIELD OF INVENTION
[0001] The present disclosure relates to agro nets used in horticulture. In particular, the present disclosure relates to an efficient and cost-effective agro polynet for a shade house that allows required sunlight, moisture, and air to pass through holes in the polynet for creating an appropriate micro-climate conducive to plant growth.
BACKGROUND
[0002] The following description of related art is intended to provide background information pertaining to the field of the disclosure. This section may include certain aspects of the art that may be related to various features of the present disclosure. However, it should be appreciated that this section be used only to enhance the understanding of the reader with respect to the present disclosure, and not as an admission of prior art.
[0003] Shade houses and/or polyhouses are used for cultivating plants, vegetables, flowers, fruits, etc. in horticulture and floriculture. The shade houses and/or the polyhouses are used in the horticulture/agriculture for a number of purposes such as weed suppression, soil warmth retention, moisture retention, soil cooling, adequate protection to the crops from a wide array of foreign elements such as birds, pests, insects, etc., and so on. The shade houses are typically made of shading nets that control sunlight, moisture, and air falling upon the crop/plants. In addition, the polyhouses are made of polyfilms for covering the crop to protect it from birds, insects, rain, hail, wind, and excessive sunlight, where the polyhouses refer to the area covered by the polyfilms and the shade houses refer to the area covered by the shading nets.
[0004] Both the shading nets and the polyfilms offer protection to the crop from the extreme weather conditions such as extreme heat and cold conditions, thus providing favourable conditions for the growth of the crop. However, the shading nets and the polyfilms have their limitations/drawbacks. For example, the polyfilms cause excessive heating within the polyhouses since there is no outlet for warm air. In addition, the polyfilm can be easily torn and therefore might get cracked/damaged.
[0005] Further, the shading nets with the high shade factor and temperature control are largely ineffective during monsoons. The ingress of excess water/moisture can damage crops within the shade houses during the rainy season. Therefore, the farmers who use the shade houses for crop cultivation, generally, keep their fields barren during the monsoon/ rainy season.
[0006] There is therefore a need in the art for an efficient and cost-effective solution which can overcome the above-mentioned and other limitations of the existing shading nets and the polyfilms.
OBJECTS OF THE PRESENT DISCLOSURE
[0007] Some of the objects of the present disclosure, which at least one embodiment herein satisfies are as listed herein below.
[0008] A general object of the present disclosure is to provide an agro polynet that can be used for horticulture and floriculture.
[0009] An object of the present disclosure is to provide an efficient and cost-effective agro polynet that allows required sunlight, moisture, and air to pass through small holes of the polynet to create an appropriate climate suitable for plant growth.
[0010] Another object of the present disclosure is to provide an agro polynet with a suitable shade factor for shade houses which can protect plants and crops from harsh climatic conditions as well as from insects, pests, and birds, and maintain favourable conditions inside the shade houses for plant growth.
[0011] Yet another object of the present disclosure is to provide a robust and cost-effective agro polynet that can overcome the drawbacks of the existing shading nets and polyfilms.
