Embodiment 1

[0017] Spray urea water with a concentration of 21% on the wheat straw with a water content of 15% using a traction-type bundling and coating machine, so that the water content reaches 30% of the mass of the wheat straw, and then sprinkle the quicklime powder on the wheat straw. The amount of quicklime powder reaches the mass of the wheat straw. 4% of the total, rounded bales, coated, transported, stored, unpacked and tested after 7 days, compared with conventional compound ammoniated wheat straw.

[0018] Result: The density of wrapped ammoniated wheat straw is 110kg / m 3 About 25% moisture, compared with conventional compound ammoniated wheat straw, crude protein (CP) increased by 17.5%, neutral detergent fiber (NDF) decreased by 7.7%, acid detergent fiber (ADF) decreased by 15.2%, acid detergent lignin ( ADL) fell 2.0%.

Embodiment 2

[0020] Use a fixed bundling and coating all-in-one machine, add a fully mixed ration mixer to mix the wheat straw with a moisture content of 10% and 14% urea water, so that the moisture content reaches 35% of the mass of the wheat straw, and then mix it with quicklime powder. The amount of quicklime powder reaches 4% of the mass of wheat straw, and then it is quickly put into a fixed baling and coating machine for round baling, coating, transportation, storage, unpacking and testing after 6 days, and compares it with conventional compound ammoniated wheat straw.

[0021] Result: The density of wrapped ammoniated wheat straw is 120kg / m 3 About 30% moisture, compared with conventional compound ammoniated wheat straw, crude protein (CP) increased by 18.6%, neutral detergent fiber (NDF) decreased by 10.3%, acid detergent fiber (ADF) decreased by 17.8%, acid detergent lignin ( ADL) fell 3.0%.

Embodiment 3

[0023] Spray urea water with a concentration of 17% on the wheat straw with a water content of 12% using a traction-type bundling and coating machine, so that the water content reaches 32% of the mass of the wheat straw, and then sprinkle the quicklime powder on the wheat straw, and the amount of quicklime powder reaches the mass of the wheat straw. 4% of the wheat straw, rounded bales, coated, transported, stored, unpacked and tested after 5 days, compared with conventional compound ammoniated wheat straw.

[0024] Result: The density of wrapped ammoniated wheat straw is 130kg / m 3 About 27% moisture, compared with conventional compound ammoniated wheat straw, crude protein (CP) increased by 19.3%, neutral detergent fiber (NDF) decreased by 12.6%, acid detergent fiber (ADF) decreased by 20.8%, acid detergent lignin ( ADL) fell 3.8%.

Abstract

The invention belongs to the technical field of feed processing and preparation and relates to wrapped ammoniated wheat straw and a making method thereof. The wrapped ammoniated wheat straw is characterized in that a composite ammoniation treatment principle is inherited, a spraying device is additionally mounted behind a picker of a traction type or self-walked bundling and wrapping integral machine, a casting device is additionally mounted on a feeder to cast quick lime powder, wheat straw is picked from a wheat field after harvesting of a combine harvester, urea water is firstly sprayed tothe wheat straw, the quick lime powder is secondly cast to the wheat straw, the wheat straw is baled into round bundles, wrapped with membranes, transported and stored, and the bundles can be taken apart for feeding 5-7 days later; and for a fixed bundling and wrapping integral machine, a total mixed ration stirring machine is additionally mounted to rapidly and uniformly mix wheat straw, water, urea and quick lime powder, the mixture is rapidly put into the fixed bundling and wrapping integral machine and is baled into round bundles, wrapped with membranes, transported and stored, and the bundles can be taken apart for feeding 5-7 days later. Through a thermal effect in straw bundles, the ammoniation time can be shortened to 5-7 days from 20 days of a common method, the efficiency is high, easiness in transportation is achieved, and on-scale commercial production can be facilitated.

Description

technical field [0001] The invention relates to wrapped ammoniated wheat straw, which belongs to the technical field of feed processing and modulation. Background technique [0002] The cell wall of wheat straw is composed of cellulose, hemicellulose and lignin, which protect the cells. Cellulose molecules are arranged regularly, aggregated into bundles, and form a cell wall structure, which is filled with hemicellulose and lignin, and the cell wall structure is very tight. The study of its supramolecular structure shows that cellulose is formed by interlacing crystalline phases and non-crystalline phases , in which the crystalline phase cellulose contains a large number of hydroxyl groups, forming a large number of hydrogen bonds, which directly leads to a dense crystal structure, which seriously hinders the effective contact and action of rumen microbial enzymes with the cellulose surface, which is exactly the natural An important reason why cellulose is difficult to dige...
