The invention relates to a method for preparing an organic fertilizer by using plant residues as a raw material. The method comprises the following steps: crushing the raw material to below 20mm, stirring and mixing the broken material with animal wastes or an inorganic fertilizer; controlling the C/N ratio of the mixed materials to be (15-35) to 1 and the pH to be 6-9; adding water, so that the moisture content in the mixed materials in the step (2) is 55-70wt%; adding a first composite microbial agent to ferment; after once fermentation, raising the temperature of windrows to above 50 DEG C; and spraying a water-dispersed second composite microbial agent to ferment for the second time. With plant residues heap corruption (composting) as a biological process for succession of a microbial community, through inoculation of exogenous complex microbial agents, efficient decomposition on agricultural wastes is facilitated; different composite microbial agents are respectively added at different composting stages; and a small amount of additives (animal wastes, urea, ammonium nitrate and the like) are added, so that the composting speed is increased, and the quality of the product organic fertilizer is really improved.

The crop residue distribution apparatus and system use a horizontal crop spreader assembly and deflector door independently relatively positionable to be configurable in a straw windrowing and chaff spreading configuration in which straw flow is directed through an aperture between drive units of the spreader assembly while the chaff is directed to the spreader disposed in a lower opening; in a straw and chaff spreading configuration wherein the door closes the aperture and both straw and chaff are directed to the spreader; and in a straw and chaff windrowing configuration wherein the spreader is withdrawn from the lower opening such that the straw and chaff are both discharged therethrough to form a windrow without requiring removing disks of the spreader.

A rotary platform is provided for the harvest of specialty crops such as grass seed. In particular the conditioning rolls are removed from the header to reduce seed shatter and converging elements are added inside the conditioner opening on both sides and to the rear of the cutterbar to feed the crop around the conditioner opening corner and to the rear of the platform. Additional converging elements are provided behind the first converging elements at a angle less then 90 DEG. to the ground so as to form the top of the windrow so that there is minimal seed loss. The converging elements may or may not be powered and the angle of the second converging element can be adjustable. The rotary knives perform the cutting function more efficiently than a sickle cutterbar, and the converging elements move the crop toward the center to form a windrow with less disturbance.

A system and method for positively discharging crop residue from a combine for precisely and consistently delivering crop residue from the threshing and separating area of a combine to the combine's residue handling system or outwardly from the rear of the combine and onto the harvested field below as a windrow. The present invention can include, or operate in cooperation with, a discharge mechanism, such as a conventional discharge beater, which delivers at least some of the crop residue to a conveying mechanism of the system. The system also includes a guide mechanism including a door arrangement configurable in several alternative configurations for receiving and merging and regulating crop residue flow from the discharge mechanism and the conveying mechanism, and directing the merged flow to a desired processing mechanism, such as, but not limited to, a chaff spreader, a straw chopper and/or spreader, etc.

An automated method and system includes an automatic guidance system (AGS) and swath pattern. The AGS steers a vehicle towing a rotary baler in an “S”, or oscillatory pattern around a predetermined approximate centerline of the swath path. The oscillatory pattern may be user defined. By steering the vehicle in an oscillatory pattern referenced to the A-B line, a windrow of crop material may be distributed into an even and optimal bale size and density by the baler. Bale chamber sensors detect an imbalance of crop density and in response, AGS adjusts an interval or amplitude of oscillatory pattern

A windrow merging implement with a pick-up, a conveyor and a connecting hitch or structure is provided in combination with a mowing vehicle, with the connecting hitch being releasably secured to a rear end of the vehicle chassis. The mowing vehicle is operative to form windrows of crop in one or more of three locations, namely, a central location passing longitudinally between the wheels of the vehicle and one on each side of the vehicle. The windrow merging implement may be positioned at either side of the vehicle for picking up the windrow deposited there, and includes a conveyor structure for either depositing the picked up windrow upon or alongside the centrally deposited windrow. Also disclosed is an embodiment where the windrow merging implement picks up and displaces transversely the centrally deposited windrow. A further embodiment discloses two windrow merging implements which respectively pick up the windrows at the opposite sides of the vehicle and convey them inwardly so as to be combined with the centrally located windrow.

A latch retainer mechanism for securely holding the windrow pipe of an agricultural crop pickup.

An agricultural harvester with a flexible crop residue management system. A pivotal swath door and displaceable windrow chute are coordinated to be displaced between positions in which all of crop residue is spread laterally and another position in which straw in the crop residue is directed in a windrow by a windrow chute and the chaff is directed laterally.

The invention discloses a cultivation material composition for producing high-quality agaricus blazei and a manure-free rice straw raw material cultivation method. The invention is characterized in that: the cultivation material composition comprises the following raw materials in part by weight: 1,000 to 1,500 parts of rice straw, 33 to 45 parts of ammonium bicarbonate, 35 to 45 parts of calciumsuperphosphate, 35 to 40 parts of gypsum and 34 to 50 parts of lime; and the rice straw raw material cultivation method comprises: raw material preparation and processing, namely primary fermentationof windrow, mushroom house selection and disinfection, secondary fermentation of culture materials on beds in the house, inoculation and culture, earthing and fruiting management, wherein the step ofraw material processing, namely primary fermentation, also comprises special pre-piling, pile building and pile turning. The method helps to effectively solve the problem that the content of heavy metals such as cadmium in the agaricus blazei exceeds a standard. Ammonium bicarbonate is used as a nitrogen source fertilizer in the cultivation materials, so damage caused by ammonia is prevented; theprocess is simple; the management is work-saving and labor-saving; the anlages of the agaricus blazei mushrooms is uniform and the mushroom shape is desirable; the yield and quality of the agaricus blazei mushrooms are high; and the artificial cultivation scale of the agaricus blazei can be enlarged.

A crop conveying apparatus for laterally urging crop from outboard ends of a cutting header on an agricultural harvester toward an interior discharge zone for formation of a windrow or for feed to a subsequent crop processing apparatus. Helical flighting extending radially from a transversely disposed, rotatable central core defines a first profile for the auger apparatus adjacent each outboard end of the header and extending inwardly to a position near, but not co-extensive with the width of a crop discharge zone in the header. Auger flighting in the central portion of the header co-extensive with the width of the discharge zone opening features a variable profile that tapers from the first profile to a minimum profile centrally located between the side edges of the discharge zone opening to provide optimal movement of severed crop material into the discharge opening, resist entanglement and clogging of the crop material, and minimize the loss of seed from the crop stem.
