Description

TECHNICAL FIELD

[0001] The present application belongs to the field of agricultural machinery, and relates to a two-row three-fertilizer seeding device suitable for precision seeding of wide-narrow-row planting. BACKGROUND

[0002] Wide-narrow-row planting refers to a planting mode in which wide rows and narrow rows are arranged alternately. This planting mode is conducive to improving ventilation and light penetration conditions, delaying row closing, and being conducive to field management in the middle and later stages. Moreover, in high water and fertilizer plots, this planting mode is conducive to increasing density and improving yield. According to tests by an agricultural technology department, compared with equal row spacing, wide-narrow-row planting can increase yield by more than 10%; and wide-narrow-row planting can increase density by more than 10%, and the ventilation and light penetration conditions in the later stage are obviously superior to those of equal row spacing, and the lodging degree is lighter than that of equal row spacing in different years. Therefore, wide-narrow-row planting is one of effective measures for improving yield.

[0003] The precision seeding machine widely used at present is provided with fertilizer opening devices on the outside of the seeding assembly to realize wide-narrow-row seeding and fertilization. This structure design can realize ditching and fertilization at the same time through the fertilizer opening devices on the left and right sides. However, the following problems exist: (1) only one row of seeds can be fertilized with one row of fertilizer, and the fertilizer is concentrated on the outside of the narrow row, that is, on one side of the wide row, and no fertilizer is applied between the narrow row seedlings; however, in the process of plant growth, the position of the narrow row seedlings is a zone where both rows of plants need to absorb nutrients, and no fertilizer supply at this position will be extremely detrimental to plant growth; (2) unilateral fertilizer not only causes the plant roots to be unable to absorb nutrients evenly, but also has the risk of damaging the roots and burning the seedlings; (3) the soil in the narrow row is also prone to hardening, and the ground temperature is slow to recover, which affects plant growth. Therefore, it is necessary to design a precision seeding device capable of fertilizing on both sides of the plants (two-row three-fertilizer). SUMMARY
