PROBLEM TO BE SOLVED: To provide a method for embedding both bases of a mulching sheet with no need of such preceding steps that: in view of the fact that grooving a ridge and treading on both bases of the mulching sheet prior to embedding of the sheet in the soil need excessive labor, which leads to complexation of the machine body and cost rise.SOLUTION: In general, when a farm is to be used, the soil of the ridges is in a soft condition because a plowing operation is conducted beforehand. Therefore, by using a disc with a thin plate made discoid without ridge-grooving or the like, both the bases of the mulching sheet S are directly pressed into the soil. At the same time, thanks to wheels 4b which are set inside of the disc 4a to both bases of the mulching sheet S respectively and roll on the mulching sheet S in link-interlocking with the disc 4a, excessive embedding of both the bases of the mulching sheet S in the soil and wrinkles and/or damage thereof are prevented and drawing out from the roll-formed mulching sheet S is facilitated.COPYRIGHT: (C)2012,JPO&INPIT【課題】土中への埋め込み前に畝の溝きりやシート両裾の踏圧等は過大な労力を必要とし、機体の複雑化やコストアップとなっていた為、この前工程をすることなくシート両裾を埋め込む方法を提供する。【解決手段】通常、圃場を使用する場合、事前に耕転作業が行われるため畝の土壌は柔らかい状態である。このため溝きり等をせずに薄板を円盤状にしたディスクを用いることによりマルチシートSの両裾を直接押し込む。同時にマルチシートS両裾に対しディスク4aより内側に備えられ、ディスク4aと連結連動してマルチシートS上を転動するホイール4bにより、マルチシートS両裾の過度な埋め込みと皺や損傷を防止すると共にロール状からの引き出しを容易にする。【選択図】図1
