Description
Technical Field
The invention relates to a furrow opener.
Background
Wheat is the first grain crop in the world, and under the condition of the same seeding quantity and fertilizing quantity, the improvement of the yield per unit area is beneficial to saving manpower and material resources, increasing the land utilization rate, increasing the fertilizer utilization rate, reducing the production cost and improving the planting economic benefit.
In the production, the wheat seeding adopts wide-row seeding, narrow-row seeding or wide-and narrow-row seeding. The row spacing of wide row seeding is 22-27 cm, the seed belt width is 5-7 cm, and the occupied area of the seed belt is 23% -41%. The narrow row sowing machine is divided into 36 rows of 5.4 meters, 28 rows of 4.2 meters and 24 rows of 3.6 meters, namely the row spacing is consistent with 15cm. The seed belt has a width of 2-3cm and occupies 13-20% of the area. The included angle of two wheel discs of the narrow-row seeder furrow opener is 11 degrees, namely the widest distance of the openings of the two wheel discs is 8cm. The diameters of the seeding pipe and the fertilizing pipe are 4cm, the fertilizing pipe is positioned in front of the upright post of the furrow opener, and the fertilizing width is 2cm; the sowing pipe is positioned behind the upright post of the furrow opener, the sowing width is 2 cm-3 cm, namely the width of the seed belt is determined to be 2 cm-3 cm. In the winter wheat planting area, wide-row sowing and wide-narrow-row sowing are gradually developed; in spring wheat planting areas, narrow row seeding is generally adopted.
The row spacing of narrow row sowing is within 15cm, the fertilization is 2cm wide, the seed bandwidth is 3cm, the seed occupation range covers the fertilization occupation range and is wider than the fertilization range, the two are overlapped, and the blank is 12cm wide. The row spacing and the width of the seed belt seriously cause the intensive distribution of wheat seeds and the concentrated distribution of fertilizers, can not fully exert the soil fertility, can not fully utilize the fertilizers applied in the current year, and restrict the growth and yield formation of wheat. Experimental research shows that for narrow-row seeding, the occupied area of the seed tape can be increased by widening the width of the seed tape, the occupied area of a single plant can be increased, and the yield per unit area can be increased. However, the current wheat seeder furrow opener arrangement is solidified, and the need of increasing the width of the seed tape cannot be realized.
