The invention provides a double-ploughshare in-situ soil turning plough. The soil turning plough comprises a left plough body, a right plough body and other work components, wherein the used double ploughshares are arranged in a symmetrical form; the single plough body also comprises a ploughshare, a soil cutting plate, a plough chest, a plough wing and a dumping plate; the other work components comprise a plough post, a front plough supporter, a back plough supporter and a plough side plate. The in-situ soil turning plough is used as a novel cultivation tool. Compared with a conventional moldboard plough, the double-ploughshare in-situ soil turning plough is mainly characterized in that the in-situ soil turning plough can turn soil blocks lifted up during the cultivation into an originalplough furrow; the soil block lateral-moving-free original furrow turning can be realized. When the in-situ soil turning plough works, the plough post is connected onto a tractor to transmit tractionforce; along with the movement of the plough body, the ploughshare and the soil cutting plate jointly act on soil to form soil blocks; the soil blocks complete the original furrow turning under the effects of the dumping plate, the plough chest and the plough wing. The in-situ soil turning plough eliminates the defect of the lateral turnover of the soil blocks of the conventional moldboard plough,so that the plough furrows are not left in the ploughing process; the soil is turned when the plough advances; the cultivation route is conveniently optimized; the double-ploughshare in-situ soil turning plough is applied to special environments such as facility greenhouses.
