Drip-irrigation-pipe underground agricultural greenhouse system and greenhouse planting method

Abstract

The invention discloses a drip-irrigation-pipe underground agricultural greenhouse system and a greenhouse planting method. The agricultural greenhouse system includes a greenhouse and a drip irrigation pipe arranged in the greenhouse, and the drip irrigation pipe includes a water pipe and a plurality of cylindrical emitters, wherein a spiral groove is formed in the middle of the inner pipe wall of each cylindrical emitter, and an annular groove is formed at the end of the inner pipe wall of the cylindrical emitter; a silica gel cylinder is arranged in the annular groove, and a plurality of through holes are arranged on the silica gel cylinder; a stable pressure outflow cavity is formed between the outer cylinder wall of the silica gel cylinder and the annular groove, and the outer wall of the cylindrical emitter is provided with a drainage hole communicated with the stable pressure outflow cavity; a water pipe is sleeved with the cylinder emitter, and a spiral buffer channel is formed between the spiral groove and the outer pipe wall of the water pipe; a pressure regulating cavity is formed between the inner cylinder wall of the silica gel cylinder and the outer pipe wall of the water pipe, and the pressure regulating cavity is communicated with the spiral buffer channel. Through the drip-irrigation-pipe underground agricultural greenhouse system and the greenhouse planting method, the improvement of the reliability of the agricultural greenhouse system is achieved.

Description

technical field [0001] The invention relates to the technical field of agricultural greenhouse system irrigation, in particular to a drip irrigation pipe buried 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 tu...

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.
