Embodiment Construction

[0023] The present invention will be described in detail below through specific examples.

[0024] In Guizhou and other southwestern hilly areas, build a drought-resistant rain-collecting degradable mulch film and integrated drip irrigation system for water and fertilizer. The invention is suitable for drought-resistant, environmental protection, energy-saving, and water-saving irrigation of crops in hilly areas. This example takes the production of irrigated flue-cured tobacco as an example. First, it is The construction of the rainwater storage system, the rainwater collection system includes laying the rainwater collection film 20 on the ridges 18 and 19 between the ridges and the rainwater collection pool 1 under the planting slope 17, and the construction volume of the rainwater collection pool is 5m 3 -6m 3 Standard, 5m 3 The rainwater collection pond is constructed as 2m×2.5m×1m; 6m 3 The rainwater collection pond is constructed as 2.5m×2.6m×1m. 5m 3 and 6m 3 Two s...

Abstract

The invention discloses a drought resisting and rainwater collecting and water and fertilizer integration drip irrigation system in hilly and mountain areas. The system comprises a rainwater collecting system, a power generation system and a water and fertilizer drip irrigation system; the rainwater collecting system comprises a rainwater collecting surface laid between ridges and a rainwater collecting tank arranged below the rainwater collecting surface, and the rainwater collecting surface is formed by laying a degradable nano water retention mulching film; the power generation system comprises a solar cell panel, a wind driven generator, a biogas power generation device and a power battery device; the water and fertilizer drip irrigation system comprises a drip irrigation pipe and water and fertilizer irrigation equipment. Accordingly, the system is novel in design and safe and reliable in operation, rainwater is converted on the spot, natural rainfall is used for resisting drought, and the rainfall resource is effectively utilized; the degradable nano water retention mulching film has the using features of an ordinary mulching film and can be degraded, residues obtained after degrading can be absorbed and utilized by soil microorganisms, crop growth is effectively promoted, secondary pollution is avoided, damage of unreasonable irrigation and fertilization to soil structure is avoided, the water and fertilizer resources are effectively saved, the cost is lowered, and precise irrigation and fertilization are achieved.

Description

technical field [0001] The invention belongs to the fields of agricultural drought resistance, environmental protection, energy saving and water saving irrigation, and in particular relates to a drip irrigation system for drought resistance and rain collection in hilly and mountainous areas and integrated water and fertilizer. Background technique [0002] The shortage of water resources is one of the key factors restricting the development of agriculture in my country, especially in Guizhou and other southwestern mountainous areas of China. Although the rainfall is relatively abundant, extreme weather such as drought often occurs, resulting in drought and water shortage for crops in hilly areas. The main way to solve this problem is to build rainwater collection ponds in hilly areas for regulation and storage. In recent years, with the aggravation of smog weather, people pay more and more attention to the protection of the environment, and the burning of agricultural wastes ...
