| titleOfInvention | Even quantitative irrigation and fertilization equipment |
| abstract | The invention relates to uniform and quantitative irrigation and fertilization equipment which comprises an irrigation and fertilization film, wherein the irrigation and fertilization film is made of a flexible waterproof material and is laid on an irrigation ditch in a plane open structure, the shape of the irrigation and fertilization film is changed randomly along with the shape of the irrigation ditch, water outlet holes with certain diameter and density are regularly and uniformly distributed on the irrigation and fertilization film, irrigation fertilizer water slowly enters soil from the water outlet holes to realize uniform irrigation and fertilization, the width of the irrigation and fertilization film is 30-100 cm, the diameter of the water outlet holes is 1-3 mm, the area proportion of the water outlet holes on the film is 0.013-0.088%, the water outlet holes are not arranged in a range of 3-6 cm away from the outer edges of two sides of the irrigation and fertilization film, and a water blocking device is arranged at the joint position of the irrigation ditch and the irrigation ditch. |
