Phragmites communis (Cav.) Trin. ex Steud. silage and preparation device used for freshwater fish farming

Abstract

The invention discloses phragmites communis (Cav.) Trin. ex Steud. silage and a preparation device used for freshwater fish farming. The phragmites communis (Cav.) Trin. ex Steud. silag comprises phragmites communis (Cav.) Trin. ex Steud., bran, table salt and sodium carbonate anhydrous. The phragmites communis (Cav.) Trin. ex Steud. is smashed and put in a sealed anoxic storage tank to be fermented, and then, the bran and the sodium carbonate anhydrous are added to be stirred. The preparation device used for the freshwater fish farming comprises a smashing bucket, a first motor, a second motor and an electric pushing rod, wherein the outer surface of the smashing bucket is welded with a feeding bucket and an extrusion pipe; the extrusion pipe is arranged on the left side of the feeding hopper; the inner side of the extrusion pipe is provided with an extrusion roller; one side of the extrusion roller is provided with a smashing rod; the outer surface of the smashing rod is sheathed with a smashing blade; the top end of the smashing rod is connected with the output end of the first motor through a coupling; a partitioning plate is inserted into the inner side of the bottom end of the smashing bucket; and the outer surface of the bottom end of the smashing bucket is welded with a supporting plate. According to the invention, the manufacture efficiency of the phragmites communis (Cav.) Trin. ex Steud. silage is greatly improved, and the input cost of equipment is reduced.

Description

technical field [0001] The invention relates to the technical field of fish farming, in particular to a reed silage for freshwater fish farming and a preparation device thereof. Background technique [0002] Reeds can be green fed, dry fed, or made into silage. According to experimental data, when reeds are firm, the water content is 7.52%, the crude protein is 9.52%, the crude fat is 1.62%, the crude fiber is 26.92%, and the nitrogen-free extract is 38.02%. on straw. [0003] 9.52% of crude protein, 1.62% of crude fat and 26.92% of crude fiber in reed silage are very suitable for freshwater fish to absorb, and the growth conditions of reed are not picky, so that the output of reed is very high, and the input cost of making silage with reed is low . [0004] In this regard, Chinese Patent Publication No.: 201810594470.3 discloses a feed for freshwater fish farming and a processing method thereof. The raw material composition includes the following parts by weight: 2 to 4 ...
