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] like 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 spring...

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] like 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 the a...

Abstract

The invention belongs to the technical field of wheat planting, and in particular relates to a method and equipment for water-air coupling and moisture preservation of wheat with grass-covered grass film. The invention mixes corn stalks, soybean straw and weeds planted in summer crops and presses them with a press to form a grass film. After the wheat is sown, the grass film is laid on the top of the wheat with a film-laying and punching machine to protect the moisture and fertilizer of the wheat. At the same time, a film-laying and punching machine is provided. Drilling, easy to use, provides mechanical support for the above moisture conservation method, and facilitates mechanized operations.

Description

technical field [0001] The invention belongs to the technical field of wheat planting, and in particular relates to a moisture-conservation method and equipment for wheat by piercing holes and covering grass film with water-air coupling. Background technique [0002] With the continuous expansion of cultivated land in recent years, the demand for water for crops has increased, and dry-fed wheat in some areas is facing water shortages, resulting in reduced wheat yields and affecting farmers' income. In order to alleviate this contradiction, new dry-fed wheat planting models should be vigorously promoted. [0003] Moisture and fertilizer conservation of dry farming technology is the focus of research, thicken the depth of the soil plow layer, expand and establish a good soil reservoir capacity, increase the infiltration of precipitation, and achieve the purpose of water storage and moisture conservation, thereby providing guarantee for dry farming agriculture, cultivating Fert...
