Corn stalk silage operation points

Corn stalk contains 30% or more of carbohydrate, 2% to 4% of protein, and 0.5% to 1% of fat. It is rich in nutrients, and it is used as a silage to feed pigs, chickens, ducks, cattle, sheep and other livestock. Poultry can not only improve the disease resistance of livestock and poultry, but also reduce the cost of feeding. However, the conventional silage method not only has a long fermentation time, quality is not guaranteed, but also has a low success rate. Therefore, in the silage, a professional silage starter should be added to promote fermentation. For example, making silage with a golden gourd silage starter has a higher success rate than conventional silage. The appearance, color, taste, odor, bacterial protein, crude protein, and nutrient conversion rate of the feed are greatly improved in all aspects, and the quality is improved. Okay, so the price is better. The specific operating points are as follows:

1. Timely harvesting: corn silage making silage is best harvested during milk ripening.

2. Rapid transportation: Corn stalks should be transported to the silage site in time after harvesting to prevent water evaporation, cell respiration and material oxidation resulting in nutrient loss.

3, the appropriate material length: generally cut corn stalks 2-3 cm, in order to facilitate the cellar, solid, compaction, exhaust, while the settlement is more uniform, less nutrient loss. In addition, short-cut corn stalks can ooze a lot of juice, which is conducive to the growth of lactic acid bacteria and speed up the silage process. For silo kiln, more attention should be paid to the compaction of the four-wall raw material, so that the oxygen content in the material can be reduced as much as possible.

4, fast loading: In the process of modulation of silage, we must seize the time, focus on manpower, equipment, engage in surprise, shorten the exposure of raw materials in the air, the faster the better the cellar. If you extend the storage time, in addition to the loss of nutrients due to the effects of plant cell respiration. At the same time, the temperature rises due to the respiration and causes the proliferation of miscellaneous bacteria, resulting in a decrease in the quality of silage.

5, spread the material storage pits: 5 tons of silage materials silage silage starter 1 kg. The gold baby silage starter is diluted with rice bran (wheat bran or corn meal) in a ratio of about 1:10, sprayed with water, and the moisture of the material is adjusted to 60-70%. Whether the water is suitable or not is judged by the method: grab a handful of materials, see the watermark is not dripping water, landing can be dispersed. The moisture content of corn stalks is adjusted to 60-70%, (if the humidity is high, some dry stalks can be added, if the humidity is small, some fresh sweetpotato pods, etc. can be added, and water can be added to adjust), and then the cellar will be installed. Step on the side, while loading raw materials, while spreading the starter, each time about 30 centimeters, step on the actual one, especially when the edge is stepped as much as possible, fill the whole cellar as much as possible.

6, cover the grass soil: loading capacity to be higher than the edge of 30 cm to prevent silage sinking. Surround with a wooden board, etc., remove the board after sinking for 2 or 3 days, cover with a layer of grass that is cut to 5 to 10 centimeters in length and about 20 centimeters in thickness, then cover the soil and press it. The thickness of the cover soil is 60 centimeters. In the shape of a hoe, take a flat surface and dig a drain around the pit. The first few days should pay attention to the inspection and found that the cover cracks repaired in time. When the silage is produced by the plastic film covering method, the other steps are the same as the general silage, but it should be noted that after the final covering of the plastic film, the soil is pressed or pressed with other heavy materials, and the film should be tightly sealed to prevent air leakage.
