The invention relates to
straw cutting, fertilization and seeding agricultural machines, in particular to a
straw cutting, fertilization and seeding all-in-one
machine. The
straw cutting, fertilization and seeding all-in-one
machine comprises a straw cutting
machine and a seeding machine, a traction rod and an upper hanging rod of the straw cutting machine are connected with a traction shaft and a lifting rod of a
tractor respectively, and a power shaft of the straw cutting machine is connected with a gearbox of the
tractor. The rear portion of the straw cutting machine is connected with a combined seed and
fertilizer drill. Cutters of the straw cutting machine correspond to the longitudinal positions of a fertilization
plough leg and a seeding
plough leg of the combined seed and
fertilizer drill in a front-and-back mode. The machine has the advantages that the straw cutting machine is additionally arranged on the front portion of the seeding machine, two sets of cutters are firstly adopted to
cut straw in a reverse-phase alternate mode, and therefore the corn straw can be
cut into short sections with
proper length conveniently. On the one hand, the
nutrition of the straw can be kept; on the other hand, the
cut straw in the land is short, and good conditions are created for seeding. In particular, the soil of the land with the straw cut is loose, the fastland soil
moisture conservation effect is good, surface
air drying of wet land is facilitated, and seeding of crops is facilitated. The fertilization and seeding quality is high.
