A method of forming filtering holes on sowing sieve is provided. The method is used for laying out sieves. The method includes: defining a first circle defining four quadrants referring to the center of the first circle equidistantly setting up filtering holes on each circumference of the first circle in the four quadrants. Accordingly, the effective use area for planting is increased. Furthermore, a sowing sieve and a plant sowing method are also provided.一種篩孔佈設方法,適用於篩片。篩孔佈設方法包括下列步驟。在篩片上定義第一圓形。以第一圓形的圓心為基準,定義四象限。等距地在第一圓形的每一象限之圓周上佈設篩孔。基此,可提高栽種植物時的有效利用面積。此外,一種播種篩片及植物播種方法亦被提出。S601、S603、S605:植物播種方法的步驟。
