Preparation method of whole corn silage

Abstract

The invention provides a preparation method of whole corn silage. The preparation method comprises the following steps: cleaning and disinfecting a silage silo, digging drains around the silage silo, paving plant fibers on the bottom of the silo and paving a separating membrane on the wall of the silo; harvesting corn plants and chopping the whole plants in the milk-ripe stage of corn; filling and compacting silage raw materials layer by layer until the height of the silage raw materials exceeds the silo depth, and after filling, sprinkling table salt on the top layer of the silage raw materials; and covering the silage raw materials with the part of the separating membrane outside the silage silo, sequentially paving a waterproof membrane and a light-shading membrane on the separating membrane, placing a balancing weight on the light-shading membrane, and fermenting the silage raw materials in the silage silo so as to obtain silage. The silage prepared by the method disclosed by the invention is free from the addition of any silage additive, therefore preparation cost is low; and the silage prepared by the method disclosed by the invention is good in palatability and high in nutritive value, and corrosion rate is less than 1%.

Description

technical field [0001] The invention relates to a method for preparing silage, in particular to a method for preparing whole-plant corn silage. Background technique [0002] Silage refers to a kind of succulent feed with special aroma and rich nutrition, which is made by cutting fresh green plant raw materials into airtight containers and fermenting them with microorganisms. Silage has the characteristics of fragrant smell, tender and juicy, yellow-green color, good palatability, low content of anti-nutritional factors (such as cyanogenic glycosides, nitrates, etc.) in forage grass, and less waste. ), the main source of roughage, silage can preserve the characteristics of green and juicy feed for a long time, and it is a good way to solve the shortage of forage supply in winter and ensure the supply of high-quality forage for livestock. [0003] Corn plants have the characteristics of good fermentation quality and high nutrient content. Except for sugar cane and cassava, co...

Problems solved by technology

[0003] Corn plants have the characteristics of good fermentation quality and high nutrient content. Except for sugar cane and cassava, corn is the crop with the highest digestible nutrient content per unit land area, and corn can be mechanically harvested and processed at any time of the year Therefore, corn plants have become the main type of silage. Traditional corn silage only uses corn stalks as silage raw materials. Since the corn stalks are not yet fully mature when the corn stalks are harvested, a large amount of corn grains is wasted.

[0004] Although many farms have spent a lot of money to build large-volume silage pits, due to poor sealing and waterproof performance, the silage produced has more mildew and rot, and the quality is poor; Livestock eat food, resulting in a lot of waste of resources; some farms add silage additives to silage raw materials in order to ensure the output and quality of silage, which increases the cost of silage preparation
