Background technique

The formation of wheat yield depends on the coordination between individuals and groups. Excellent population structure is conducive to ventilation and light transmission in the canopy of wheat populations, making individual growth and development robust, and promoting the increase of wheat yield. Drill sowing is the main method in traditional wheat production, with uneven seed spacing and large seeding volume, which is not conducive to high yield. The precision sowing of wheat wide seedling belt can make the seeds evenly distributed in the field, and each plant can obtain enough nutrient area and space, absorb water and fertilizer to the maximum, effectively carry out tillering, and increase the number of ears of wheat, with large ears and sufficient grains. It has the effect of increasing production and income, while reducing the amount of sowing and reducing operating costs.

Wheat wide seedling strip fertilization technology is a method to uniformly sow quantitative chemical fertilizers into the soil and cover soil according to the row spacing, seedling strip width and fertilization depth required by agronomy by mechanized means, and at the same time create a soft and flat seedbed environment for wide seedling strip sowing Mechanized deep fertilization technology. Wheat seedlings planted in wide seedling strips have wide width and large row spacing. The ideal fertilization of wheat wide seedling strips can ensure the uniform supply of nutrients for all plants on the strips, and effectively avoid the lack of regional nutrient supply caused by uneven fertilization and the loss of nutrient elements at excessive fertilization. .

detailed description

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

The utility model relates to a lower uniform fertilization device with a wide wheat seedling belt, which includes a ditch opener and a soil covering device, which are fixed on the frame of a wide wheat seedling belt fertilizing seeder and located at the lower part of the fertilizer discharger.

The ditch opener comprises support leg 1, share tip curved panel 12, fertilizer retaining plate 4, fertilizer distribution plate 5, side baffle plate 6, rear baffle plate 8 and upper cover plate 13; Support leg 1 has fertilizer discharge channel, and is connected with wheat The fertilizer outlet of the wide seedling band fertilizing planter is connected; the curved panel 12 of the share point is located in front of the support leg 1; the fertilizer retaining plate 4 is located obliquely below the support leg 1; It is located under the fertilizer discharge channel; the side baffle 6 is located behind the curved panel 12 of the share tip, and is located on the left and right sides of the leg 1; the rear baffle 8 is located behind the leg 1; Plate 6 and tailgate 8 are welded as a whole to form a cavity that only has an opening at the bottom and other surfaces are closed, and the lower part of the supporting leg 1 stretches into the cavity. With the above structure, when the fertilizer is discharged, it flows out through the fertilizer discharge channel of the leg 1, and falls on the fertilizer retaining plate 4 and the fertilizer distribution plate 5, through the continuous rebound on the fertilizer retaining plate 4 and the diversion of the fertilizer distribution plate 5 , spread evenly on the bottom of the fertilizer ditch opened by the opener, and the curved panel 12, the side baffle 6, the rear baffle 7 and the upper cover 13 are welded together to form a relatively closed cavity, so that the fertilizer has Enough space to spread out evenly, and at the same time prevent backfill soil from flowing into the upper part, both sides and the rear of the opener, so as to prevent soil backflow from affecting the uniform distribution of fertilizer, or soil from entering the inside of leg 1 to block the fertilizer discharge channel.

The earth covering device includes a soil pressing board 9 connected with the ditch opener and soil scraping boards 8 located on both sides of the soil pressing board 9 . The soil pressing board 9 is a bent structure, and the section of the soil pressing board 9 includes a vertical surface 9-1, a backward inclined inclined surface 9-2, and a horizontal plane 9-3 connected with the inclined surface 9-2, and the inclined surface 9-2 The angle with the horizontal plane is 30-45 °, and the both sides of the soil pressing plate 9 are the soil-hugging surfaces bent forward. The soil scraper 8 is welded together with the edge of the soil raking surface and the edge of the inclined surface, which can enhance the effect of scraping the soil. After the fertilization of the opener part is completed, the soil cover part passes through the scraper 8 and the pressure plate 9. The soil on the soil surface gathers the soil on both sides of the fertilizer ditch into the fertilizer ditch, and smooths the gathered backfilled soil by the soil pressing plate 9 to form a flat and uniform wide seedling seedbed for wheat. The width of soil pressing plate 9 is enough to guarantee that the soil gathered up will fill up the fertilizer ditch, and the angle between the lower edge of soil scraping plate 8 and the horizontal plane is less than the natural angle of repose of soil, so as to prevent the backflow of soil from scraping the soil and bury the seedbed belt.
