A combine harvester has a straw chopper attached to a rear hood behind the rear edge of the sieve assembly with a chaff guide system to bypass the chaff in front of the chopper and a straw guide system to bypass the straw above the chopper and over the tailboard. The chopper has a housing with a feed opening into which straw and/or chaff can be fed depending upon the positions of the chaff guide system and the straw guide system. A chopping assembly mounted in the housing discharges through a discharge opening through onto the tailboard having a plurality of guide fins for spreading. The housing bottom wall has a pivotal adjustment portion to allow chaff entering the feed opening and engaging the chopping assembly to discharge from the housing at a discharge position different from the discharge opening for spreading onto a supplementary spreading device.

A straw and chaff chopper is mounted at the rear hood of a combine harvester and includes a housing with a feed opening and a discharge opening and a rotor mounted in the housing comprising a hub with a plurality of blades mounted on the hub for chopping the fed materials and accelerating the chopped materials for discharge. A tailboard has a plurality of guide fins arranged relative to the housing so as to receive the chopped materials from the discharge opening to engage onto a guide surface and guide fins of the tailboard construction for spreading of the chopped materials. The tailboard is divided longitudinally into first and second separate tailboard portions, each arranged to receive a portion of the chopped materials and each being adjustable in angle to raise and lower independently of the other so as to provide a different spreading effect on the portion received thereon. Fins on the portions prevent the materials entering the gap. Adjustment on the go from the cab can be provided.

A system for chopping and spreading crop residue produced by an agricultural combine wherein the spreader is advantageously disposed directly rearwardly of a cleaning system of the combine for receiving chaff and other crop residue directly therefrom, without aid of a mechanism to convey the chaff to the spreader, and wherein the chopper is disposed just above and/or rearwardly of the spreader and is configured for discharging crop residue from the threshing system of the combine into the spreader for spreading thereby with the chaff.

The present invention consists of the particular geometry of the reflectors or dispersers which constitute the anti-radar chaff cloud. Instead of using conventional rectilinear forms, in the present invention multilevel and space-filling forms are introduced. Due to this geometric design, the properties of the radar chaff clouds improve mainly in two aspects: radar cross-section (RCS) and mean time of suspension.

The invention provides a breeding method capable of changing the glume color of rice varieties with yellow glume to brownness. The breeding method comprises the following steps: selecting a target fragment in an extron region of a glume color determining gene OsCAD2, constructing a plant CRISPR/Cas9 targeting recombinant vector, guiding the recombination vector into a rice cell, regenerating the rice cell into seedlings, and sequencing genome target fragments of regenerated strains so as to obtain the strains, two allelic genes OsCAD2 of which simultaneously suffer function deletion mutation. Through phenotype identification, the change of the glume color is realized. Experiments prove that the breeding method can quickly change the glume color of the rice varieties.

Weed seeds are destroyed in the chaff from a combine harvester by repeated high speed impacts caused by a rotor mounted in one of a pair of side by side housings which accelerate the discarded seeds in a direction centrifugally away from the rotor onto a stator including angularly adjustable stator surfaces around the axis. Thus the discarded seeds rebound back and forth between the rotor and the stator to provide a plurality of impacts. The seeds are carried axially of the rotor by a controlled airstream so that they move to an axial discharge location where a discharge fan is mounted. The angle of the discharge around the rotor axis can be changed to direct the seeds to the side of the combine away from a straw chopper, towards the guide fins of the tailboard of the chopper, or into the housing of the straw chopper.
