Problems solved by technology

[0004] However, when the whole corn stalks are silaged, because the corn stalks are not easy to compact, it is difficult to discharge the air, and the suitable fermentation conditions for lactic acid bacteria cannot be satisfied, and the ideal silage effect cannot be achieved.
According to reports, some people have used methods such as adding corn flour and salt, which have a certain improvement effect, but the whole corn stalk silage is still rotten and mildewed

Embodiment 1

[0031] Such as figure 1 As shown, it is a schematic view of the structure of a silo according to the embodiment of the present invention when viewed from above, figure 2 for figure 1 Middle A-A view. The silo 20 of the present invention is arranged below the ground 10 . The silo cellar 20 is high and dry, and the groundwater table is low and digs a rectangle, or is piled up by concrete, and its surroundings are smooth, airtight, and watertight. After the silo 20 was completed, the whole corn stalks were ensiled according to the following steps:

[0032] Step 1: bottom and surrounding treatment;

[0033] Spread some grass powder 21 at the bottom of the silo pit 20 to facilitate the fermentation of the whole corn stalk and exhaust during silage, then spread the wide plastic film 22 on the bottom and four walls of the silo pit 20, the plastic film 22 adopts Non-toxic polyethylene plastic film with a thickness of 0.1mm to 0.2mm.

[0034] Step 2: configure urea solution;

Embodiment 2

[0041] Such as image 3 Shown is a schematic diagram of the cross-sectional structure of the silage pit in Embodiment 2 of the present invention. When the amount of corn stalk silage is large, it can be compacted with heavy-duty machinery, such as a tractor, so that its exhaust effect is good and it saves time and effort. Such as image 3 Among them, only part of the silo 20 is set under the ground 10, and the height of the underground part is h3. The part of the compacted corn stalk layer 23 protrudes from the wall of the silo 20, and the protruding height is h1, and the range of h1 is 50cm-60cm. After the corn stalk layer 23 is tightly sealed by the plastic film 22, one deck of wheat straw 24 is spread on the upper end. Then the outermost layer is covered with a layer of wet soil layer 27, and the surface is patted lightly. The thickness h2 of the wet soil layer 27 is 20cm-30cm.

[0042] In the silo 20 of the present invention, the width W of the silo 20 is the same as ...

Abstract

The invention relates to a silage method of whole corn stalks. An underground silo is used for silaging the whole corn stalks. The silage method comprises the following steps of the treatment of bottom and periphery, preparation of a urea solution, pavement of corn stalks, compaction, corrosion resistance and taking. According to the silage method, spoilage bacteria do not easily enter the stalks, thereby being favorable for preservation of the stalks; urea is decomposed into ammonia and carbon dioxide, both of which can inhibit the activity of spoilage bacteria and have a corrosion resistance effect; and the decomposed ammonia provides non-protein nitrogen for microorganisms in the rumen of a ruminant to form microorganism proteins, thereby increasing the protein nutrition level and the biological value of the corn stalks. The silage whole corn stalks are dark green in color, are soft and juicy, are moderate in sweetness and sourness, and have good palatability and a higher operating value. The method is simple to operate and is easy to learn, and eases the labor shortage problem in autumn.

Description

technical field [0001] The invention relates to a silage method for whole corn stalks, which realizes long-term freshness preservation of whole corn stalks and belongs to the field of biotechnology. Background technique [0002] In the vast agricultural areas, it is labor-intensive and time-consuming to cut corn stalks into silage while harvesting grains. If corn stalks are not collected and stored in time, they are easy to rot and mildew, and dry corn stalks have high crude fiber and lignin content, coarse Hard, poor palatability, low digestibility. [0003] After the whole corn stalks are ensiled, the corn stalks are green in color, soft and juicy, moderately sweet and sour, and have good palatability. The whole silage corn can be well eaten by sheep, and there will be no leftovers. [0004] However, when the whole corn stalks are ensiled, because the corn stalks are not easy to compact, it is difficult to discharge the air, and the suitable fermentation conditions for l...
