Drip irrigation and water supply agricultural greenhouse system and greenhouse planting method

Abstract

The invention discloses a drip irrigation and water supply agricultural greenhouse system and a greenhouse planting method. The agricultural greenhouse system comprises a greenhouse and a drip irrigation pipe arranged in the greenhouse, the drip irrigation pipe comprises a water pipe and a plurality of cylindrical water droppers, a spiral groove is formed in the middle of the outer pipe wall of each cylindrical water dropper, a water inlet communicated with the corresponding spiral groove is formed in the inner pipe wall of one end of each cylindrical dripper, an annular groove is formed in the outer pipe wall of the other end of each cylindrical water dropper, and silica gel barrels are arranged in the annular grooves; a plurality of through holes are formed in the silica gel barrels, and a pressure adjusting cavity is formed between the inner barrel wall of each silica gel barrel and the corresponding annular groove; the cylindrical water droppers are arranged in the water pipe, and spiral buffer channels are formed between the spiral grooves and the inner pipe wall of the water pipe; pressure stabilization outflow cavities are formed between the outer cylinder walls of the silica gel barrels and the inner pipe wall of the water pipe, water outlets are communicated with the corresponding pressure stabilization outflow cavities, and the pressure adjusting cavities are communicated with the spiral buffer channels. The use reliability of the agricultural greenhouse system is improved.

Description

technical field [0001] The invention relates to the technical field of agricultural greenhouse system irrigation, in particular to a drip irrigation water supply agricultural greenhouse system and a greenhouse planting method. Background technique [0002] At present, the planting technology of the agricultural greenhouse system has been widely promoted, and the agricultural greenhouse system combined with the drip irrigation technology has become the current trend of green and environmentally friendly agricultural development. The drip irrigation pipe is generally laid on the surface of the greenhouse. The drip irrigation pipe usually includes a water pipe and a dripper. The dripper is arranged on the inner wall of the water pipe. A turbulent flow channel is formed between the dripper and the water pipe. out of the water outlet. However, in the actual use process, because the drip irrigation pipe touches the ground, the sediment is easy to enter the water outlet, and the t...

Problems solved by technology

However, in the actual use process, because the drip irrigation pipe touches the ground, the sediment is easy to enter the water outlet, and the turbulent flow channel of the dripper is easy to be removed from the outlet due to its small size and many detours, corners, and dead ends. The silt that enters the water port is clogged, which leads to the failure of the dripper, and the corresponding crops cannot obtain sufficient water supply, which affects the growth, resulting in low reliability of the drip irrigation pipe.
