Description
Technical Field
The invention relates to the technical field of silage preparation, in particular to a small-size portable corn and soybean mixed silage fermentation tank.
Background
The silage is a coarse fodder obtained by cutting green fodder with water content of 65-75%, and inhibiting propagation of various mixed bacteria under the condition of closed oxygen deficiency by the fermentation effect of anaerobic lactobacillus. The silage is sour and fragrant in smell, soft and juicy, good in palatability, rich in nutrition, beneficial to long-term storage and is an excellent feed source for livestock. With the development of animal husbandry and the demand for high quality roughage, silage accounts for a large proportion of roughage.
The nutritional quality and fermentation quality of silage is often affected by silage material. Corn has high non-structural carbohydrate content, provides fermentation substrate for lactic acid bacteria, enables pH to be rapidly reduced, is easy to ensile, has high lignin content and good palatability, is easy to digest and absorb, and is often used for preparing silage. However, the corn has low protein content, and the pure utilization of the corn to prepare the silage cannot meet the requirement of the corn on preparing high-quality silage. The soybean is both protein crop and oil crop, has higher digestibility than corn, and the straw is good coarse fodder for cattle and sheep. However, due to the low carbohydrate content of soybeans, the buffering capacity is high, which prevents the rapid decrease of pH during ensiling, and ensiling alone is difficult to succeed.
Most of the existing corn and soybean intercropping production modes focus on grain seed production, and the existing reported scheme for preparing silage after intercropping only focuses on protein content and ignores fermentation quality and other nutritional ingredients. The organic acid content (including butyric acid) of the mixed silage reported in the prior art is higher than that of the corn silage alone, particularly, the butyric acid content is more than 1%, and the ammoniacal nitrogen/total nitrogen content is more than 10%, and the two indexes exceed the safety limit, which indicates that a lot of proteins in the mixed silage are ammoniated, are unusable proteins, are seriously degraded and belong to rotten feeds. Moreover, the content of Neutral Detergent Fiber (NDF) and Acid Detergent Fiber (ADF) after mixed silage reported in the prior art is higher than that of single-purpose corn silage, which shows that the digestibility is reduced after mixed silage.
Meanwhile, the air tightness of the silage fermentation tank is an important guarantee for ensuring the fermentation quality, and development and utilization of small silage tests, silage fermentation quality detection, silage leavening agent screening and novel silage materials are significant through development of the small easily-controlled silage fermentation tank, so that the development of silage industry is accelerated, and healthy breeding of ruminants is promoted. In the prior art, the small-sized silage fermentation tank has poor sealing performance, so that the fermentation of the feed is influenced, the fermentation time is prolonged, and the fermentation quality of the feed is influenced. Moreover, because the silage fermentation tank is mainly applied to actual production, the sampling degree of difficulty is very high, if: difficult temperature change detection, inconvenient exudate collection and difficult control on the growth condition of microorganisms in the cellar.
