First, we must chop the forage, chop it to ensure compaction, and remove the air; second, compaction, and the smaller pit side can be pressed with a small four-wheel tractor. Some peasant households do not need to do so because of their small scale. They can dig a simple pit, shovel it clean, put plastic sheeting on, and be airtight and breathable. Such an environment will do. The cellar can be stepped on by people to achieve the purpose of discharging air. In the course of this production, add a little salt. Some people think that adding a little more salt, like salted pickles, is not bad, but this is not the truth. In the process of making silage, salt is added to supplement minerals and salt and increase its palatability. The amount of salt we add should generally be 0.5%, and no more than 0.6%, which is a ton of silage corn plus 5 kg to 6 kg of salt. Silage corn silage is not recommended to add urea. In some places, adding urea is mainly to provide some non-protein nitrogen in the feed. When ruminants are fed, such as cattle, sheep, and camels, there are a lot of microorganisms in the rumen of the animal. The microorganisms use the nitrogen-producing bacteria in urea. The body protein and the bacterial protein are absorbed and utilized by the animal as nutrients, and it may or may not be added when silage is done. Some farmers have the same reason to add urea when feeding ruminants. The theoretical data for moisture is 70% to 75%. In practice, grab a handful of silage and squeeze it hard. If the water droplets run down, the water is high. After the water is made of high-silage, the temperature will increase, which will affect the quality of the silage. The best moisture content is 70% to 75%, which is just a little bit of water seeping from the finger joint. This standard is 70%~ 75%. Silage also has some precautions: First, the requirements for raw materials. For example, corn such crops, it must be the ear, grow into the best milk maturity, but the most basic requirements to ear; second, in the production process, must be clean air, the ultimate goal is to cause An anaerobic environment; Third, after the entire pressure is over, it must be sealed and impervious to air in order to ensure the quality of silage.
