Problems solved by technology

As far as the current situation of alfalfa silage in my country is concerned, large-scale silage is suitable for cellar storage and tower storage. Although stretch-wrapped silage has a high degree of mechanization, the cost of machinery and stretch film materials is high, and stretching is not easy to handle. Membranes can also cause environmental pollution

Abstract

The invention discloses an alfalfa half-dry bagged silage method which can be used for solving the problem in harvesting alfalfa in rainy season. The alfalfa half-dry bagged silage method comprises the following steps of: harvesting, airing, chopping, packing, compacting, sealing, fermentation and the like. Through the silage regulation in the invention, relatively many nutrient substances can be stored, the texture is soft, the source and sweet fresh scent is realized, and the palatability is improved; and meanwhile, the alfalfa silage is higher than the hay product in terms of energy and protein digestibility.

Description

technical field [0001] The invention relates to the field of forage grass processing, in particular to a half-dried bagged silage method of alfalfa. Background technique [0002] Alfalfa (Medicago stativa L.) is a perennial leguminous forage, and it is also the largest forage variety in my country and even in the world. Because of its strong adaptability, high yield, and good quality, it is known as the "King of Forage Grass". my country is a country with a shortage of protein feed resources, and the development of high-quality alfalfa has become a new technology industry for the development of protein feed resources. Northern my country is the main production area of ​​alfalfa hay, but in the process of hay preparation, there are losses such as rain and fallen leaves in many places, especially in areas where rain and heat are at the same time, the loss rate of alfalfa due to rain during the harvest season is greater, resulting in the first Two or three crops of alfalfa are...
