A light source module includes a wiring board and a LED array electrically connected to the wiring board. The LED array can be driven to emit a first group of emission peaks in 300 nm≦λ.sub.max<450 nm, a second group of emission peaks in 450 nm≦λ.sub.max<550 nm, and a third group of emission peaks in 550 nm for matching the spectrum of sunlight underwater. When the maximum peak intensity of the emission peaks in the second group is taken as 1.0, the peak intensity I.sub.a of each emission peak in the first group is in a range of 0<I.sub.a≦0.9, and the peak intensity I.sub.b of each emission peak in the third group is in a range of 0<I.sub.b≦0.9. Accordingly, the light source module is suitable for aquatic species and can enhance growing rate of the aquatic species.

The invention relates to a plough module (1) with plough-following stabilisation for mounting on a base frame of a plough device, comprising a rotatable first cutting element designed as a hollow-disc cutting plate. A lateral region (122) of a soil ridge can be cut away by moving the plough module (1) on the ground along a ploughing direction (110). The plough module (1) comprises a second plat cutting element (105) with a second cutting edge (106), wherein a base region (121) of the soil ridge can be cut away by moving the plough module (1) on the ground. The plough module (1) is designed as a fully assembled unit, in which the second cutting element, designed as a fixed cutting blade (6), follows the first cutting element (102) in the ploughing direction (110). The cutting blade (6) is angled backwards relative to the working angle, achieving a dynamic balance of forces between the first cutting element (102) and the cutting blade (6) for plough-following stabilisation. A contact plate (8) is provided on the cutting blade (6), which is supported on a furrow wall (121) such that a stabilising effect follows the plough.
