Technical Field

[0001] The utility model relates to the technical field of saffron planting, in particular to a watering device for saffron planting. Background Technique

[0002] The growth period of saffron coincides with the less rainy winter and spring seasons, and special attention should be paid to irrigation. Emergence occurs about 20 days after planting. Water is irrigated once before emergence to facilitate emergence. An antifreeze water is irrigated once before winter to increase the ground temperature. Water is irrigated once in mid-April to reduce the harm of dry hot wind. The drip irrigation device is a device used for crop irrigation, and it mainly plays roles such as drought prevention, flushing, and maintaining soil moisture.

The brush plate 38 can also stir up the fertilizer that has not been completely melted and precipitated at the bottom of the water and fertilizer mixing pool 2 to make the mixing of the water and fertilizer more sufficient. Then open the feed valve 19, and use the water pump 15 to transport the mixed water and fertilizer in the water and fertilizer mixing pool 2 into the water delivery pipe 13 through the feed pipe 12, and carry out drip irrigation fertilization on the saffron through the drip irrigation pipe 14 and the drip irrigation head 18. When it is necessary to clean the irrigation pipe network 1, open the water inlet valve 110, the first sewage discharge valve 16 and the second sewage discharge valve 17, and close the feed valve 19. Use the water pump 15 to flush the inside of the water delivery pipe 13 and the drip irrigation pipe 14 with the external water source, and flush out the residual impurities in the pipeline through the first sewage discharge valve 16 and the second sewage discharge valve 17, thus completing the cleaning of the irrigation pipe network 1 and avoiding the blockage of the drip irrigation head 18, which in turn affects the irrigation operation.
