Embodiment 1
[0032] Example 1: In view of the existing wheat planting mode, the corn stalks are crushed and returned to the field. This method simply uses corn stalks, which has a high degree of fibrosis, affects the normal growth of wheat, and has poor air permeability, which cannot meet people's needs. People have brought trouble, and this embodiment provides a kind of method for water-air coupling moisture preservation of wheat piercing holes and mulching grass film, comprising the following steps:
[0033] S1, finished grass film 20: the grass film includes corn stalks, weeds and soybean stalks, and the fluffy corn stalks, weeds and soybean stalks are pressed by a press to form a grass film, and the width of the grass film is L;
[0034] S2. Soil preparation: plow the land with a rotary tiller to a soil depth of 250-300mm, and then level it.
[0035] S3, sowing: after the land is leveled, sow the wheat into the soil with a seeder, the row spacing of the wheat is N, L=nN, where n is an ...
Embodiment 2
[0041] Embodiment 2: This embodiment provides a film laying and punching machine used in the moisture conservation method in Embodiment 1.
[0042] The film-laying and punching machine includes a frame 1, travel wheels 2 arranged on the front and rear sides of the frame, a punching mechanism arranged on the rear side of the frame, a film-laying mechanism and a traction mechanism arranged on the front side of the frame; The mechanism is a tractor, the front end of the frame 1 is provided with a traction end 3, the tractor and the traction end are connected to the traction frame to walk in the field, and the film laying mechanism and the punching mechanism realize the functions of laying grass film and punching holes between rows .
[0043] Such as figure 1 As shown, the punching mechanism includes a reduction motor 4, an eccentric wheel set 5, an eccentric rod 6, an upper transmission rod 7, a lower transmission rod 11, a limit plate 10, a punching head 13 and an extension spr...
Embodiment 3
[0048] Embodiment 3: This embodiment is basically the same as Embodiment 2, the difference is that this embodiment further limits the structure of the eccentric wheel set.
[0049] The eccentric wheel group includes a left eccentric wheel 51 and a right eccentric wheel 52, the left eccentric wheel 51 and the right eccentric wheel 52 are coaxial, and the distance between the two is L / 2, that is, 750mm, that is, the distance between the holes 21 is 750mm , and the outer eccentric places of left eccentric wheel 51 and right eccentric wheel 52 are all provided with eccentric shaft 54, and eccentric rod 6 is hinged on eccentric shaft 54; Symmetrical to the center of the circle on the same projection plane.
[0050] Such as figure 2 As shown, a pulley is installed on the rotating shaft of the reduction motor 4, and the pulley is connected with a driven pulley through a belt drive, and the driven pulley is fixedly connected with a first gear 56, and a second gear is installed on th...
