Sowing method of corn sitting on water in arid and semi-arid cultivated land and supporting seeder

technical field

The invention relates to the technical field of corn sowing in arid and semi-arid cultivated land, in particular to a water sowing method for corn in arid and semi-arid cultivated land and a matching seeder.

Background technique

Water and fertilizer are two important factors affecting crop growth in agricultural production. The research on the application of water and fertilizer in agricultural production has always been paid attention to. The lack of water limits the improvement of crop productivity, and the lack of nutrients restricts the efficient use of water by crops. In the semi-arid cultivated land in northern my country, there is not only the problem of water shortage, but also the phenomenon of phosphorus deficiency, nitrogen deficiency and potassium deficiency. In order to solve this kind of problem, in the semi-arid cultivated land, the agronomy of supplementary irrigation and moisture increase is usually used to sow with water. The operation procedures are digging holes, water injection, spot planting, fertilization, soil covering and suppression.

With the in-depth research and continuous promotion of agricultural dry farming water-saving technology, a high-energy drought-resistant "soil water-retaining agent" came into being. This agricultural water-retaining agent uses a superabsorbent resin that repeatedly releases and absorbs water. After being applied to the soil, it can usually "reserve" a large amount of water, and when it is urgently needed, it will be released continuously to supply crops. . Because the water-retaining agent has the function of absorbing and storing water, it can fix the nutrients needed for the growth of crops such as soluble fertilizers in water, thereby reducing the leaching loss of soluble nutrients, saving water and fertilizer, and improving water and fertilizer utilization. Effect.

In order to improve the sowing survival rate of semi-arid cultivated land, although water-retaining agents have been applied to the agronomy of water-based sowing in semi-arid cultivated land, due to the water splashing to the seeds in the original sowing process of water-based sowing, water often occurs. Therefore, there is still the problem of water waste in the existing semi-arid cultivated land sowing method under the condition of water planting.

The four parts form a closed loop, and the curvature of part A The radius is larger than the radius of curvature of part B, the radii of curvature of parts B, C and D are the same, and the transitions between the parts are circular arc structures. For a single slide block 25, during the motion process in one cycle, because the radius of curvature of the guide plate 28 is different everywhere, therefore, the slide block 25 has different positions in the corresponding chute, and then the second spring 26 can be There are two states of accumulating and releasing,

As shown in Figure 8, in order to enable the slider 25 to move further along the guide plate 28 smoothly, the radius of curvature between the A part and the B part can be gradually reduced from large to small, and between the B part, C part and D part Partial radius of curvature between D and A is the same, and the radius of curvature between D and A gradually increases from small to large. The gradually changing radius of curvature can prolong the service life of the second spring 26 and can also reduce the impact vibration between various components.

As shown in Figures 5 to 8, further, the injection mechanism 4 also includes a guide rod 29 and a roller 30, one end of the guide rod 29 is fixed on the slider 25, and the other end is rotatably connected to the roller 30, and the outer surface of the roller 30 The edge is in rolling contact with the guide plate 28.

In this embodiment, in order to reduce the frictional force that the slider 25 is subjected to during the movement, and to ensure that the slider 25 can be stably drawn by the guide plate 28, a guide rod 29 can be set on the slider 25. The other end of bar 29 is provided with roller 30, and promptly one end of guide bar 29 connects slide block 25, and the other end connects roller 30, and rolling is connected between roller 30 and guide bar 29, and outer edge is in rolling contact with guide plate 28, like this The frictional force between the slider 25 and the guide plate 28 can be changed into rolling friction, which greatly reduces the frictional force on the slider 25 during the moving process.

As shown in Figures 11 to 12, further, the soil covering mechanism 8 also has a pressing block 31 and a pusher 32, the pusher 32 is arranged on the connecting frame 19 and has a pusher top, and the pusher moves back and forth along the vertical direction, The pressing block 31 is arranged on the top end of the pusher and is used to prevent gaps from appearing in the planting hole.

In this embodiment, if there is still a large gap in the planting hole after the soil in the planting hole is covered, it will cause water loss. In order to avoid this situation, the soil covering mechanism 8 also has a pressing block 31 and a pusher 32 , the pushing piece 32 is arranged on the connecting frame 19 and has a pushing top, the pushing top can move in the vertical direction, and the pressing block 31 is arranged on the pushing top, so that the moving of the pressing block 31 in the vertical direction can be realized, After the soil cover plate 20 pushes the soil into the planting hole, the pressing block 31 can press the soil, so as to ensure that there will be no large gaps in the soil in the planting hole and reduce the loss of water.

The above are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention within.
