Forage grass, usually grass or other herbaceous plants used for raising livestock. Its regeneration ability is strong, and it can be harvested many times a year, so it is the first choice for raising livestock. So how to fertilize artificial pasture? Which is the best way to raise cattle? How many cattle can you raise per mu?

How to fertilize artificial forage?

Fertilizing artificial forage can not only increase the yield of artificial forage, but also improve the quality of grassland and prolong the service life of grassland. There are two kinds of fertilization in artificial grassland: base fertilizer (base fertilizer) before sowing and topdressing in the growing period of forage grass.

First, base fertilizer. The purpose of applying base fertilizer is to improve soil fertility and to meet the fertilizer demand of forage and forage crops during the whole growth period. The application of base fertilizer is mainly organic fertilizer, and the organic fertilizer which is not mature well must be applied in autumn. It is generally applied every 3-4 years, 500kg ~ 1000 kg per mu. The methods of applying base fertilizer are withdrawal, strip application, layered application, mixed application and so on.

Second, topdressing. It is mainly based on quick-acting chemical fertilizer, and the type and quantity of topdressing should be determined according to the results of soil nutrient element analysis. The topdressing time of artificial forage grass should be carried out at tillering (branching) stage, jointing (heading) stage, heading (budding) stage and after each cutting, while forage crops should be carried out at stalk attack, panicle attack and grain attack stage. For the types of topdressing, grasses, mainly nitrogen fertilizer, combined with a certain amount of phosphorus and potassium fertilizer; legume grass, mainly phosphorus and potassium fertilizer, can apply a certain amount of nitrogen fertilizer at the seedling stage in the year of sowing; for the mixed pasture of bean and grass, no or less nitrogen fertilizer is applied, mainly phosphorus and potassium fertilizer; available fertilizer can be applied once a year, preferably after grazing or cutting, combined with raking irrigation.

Which kind of forage is the best for raising cattle?

First, the emperor bamboo grass, also known as sugarcane grass, its. It also has a very domineering name, that is, the king of grass. Why would you say that? Because of its strong tillering ability, a single plant can tiller 80-90 plants per year. How's it going? This is the only way to become a king in the grass. Therefore, its economy is the most valued by people.

Second, the rhizome of Mexican corn is large and straight, and its length is even more amazing, up to 4 meters, almost catching up with the tree. But it has a high demand for temperature, and generally speaking, it stops growing when the temperature is as low as 10 degrees. But it is not strict with the soil, so the economic type is relatively strong.

Third, sweet sorghum is also called sorghum sugarcane, it can be said that the whole body is a treasure. Because it grows grain on the top and sugar cane on the bottom, do you think what the editor said is very magical! Because its sugar content is comparable to that of sugarcane in the south. Its use is also very extensive, can be used to make sugar, wine, can also be used as feed, and very high quality, so its economy is the most valued by people. Because its output is also very high, as much as 20,000 kilograms.

How many cattle can one mu of pasture raise?

1. Take an 800-jin cow as an example, the dry matter mass of roughage accounts for about 2-2.5% of the cow's body weight, which means that a cow has to eat 15-20 jin of hay a day. According to the moisture content of fresh grass, a cow should eat at least 30 kilograms of fresh grass a day. A year needs 10950kg 14600 jin of fresh grass, that is, 5.4 to 7.3 tons of fresh grass.

Second, yellow bamboo grass, sweet elephant grass, Mexican corn, etc., can reach 10 to 15 tons of fresh grass in the case of high yield per mu of land. The yield of fresh grass per mu of alfalfa and ryegrass is only 23.5 tons.
