The development of artificial cultivation of pasture has become an important part of the current adjustment of agricultural structure. Planted grasses include ryegrass, sudangrass, elephantgrass, eucalyptus (Mexican corn), hybrid pennisetum, and Jianbao forage; legumes include clover, milk vetch, grasshopper, and other forages. There are a series of pine cones, leeks, grass, Rumex and so on.
The content and digestibility of various nutrients in artificially cultivated pastures are higher than that of crop stalks and close to concentrates. The proportion of various nutrients in pastures is reasonable, and the vitamin content is abundant, which is generally inferior to concentrates and straws. Forage grass is green, fragrant, and palatability is unmatched by other feeds. Therefore, high-quality forage grass feeding animals, poultry, fish, can enhance disease resistance and increase production.
Pastures have a strong life force. Perennial grasses such as dwarf grasses and pods can be used for many years after being cultivated. One year old pastures can be harvested several times in one growth period, and can guarantee the supply of livestock and poultry green feed for a long time. The use of ryegrass in winter in Hunan province, hybrids of Pennisetum sp., Sudan grass, elephant grass, or Jianbao forage grass in the winter can guarantee the uninterrupted supply of green and blue fodder throughout the year. The total nutrient yield of forage grass also exceeds that of crops, and the whole plant can be better utilized by livestock, poultry and fish. The economic benefit of planting grass and raising livestock on the same amount of land is much higher than that of planting food and raising livestock. The income of planting 667 square meters of high-quality forage grass in Hunan is more than 1,000 yuan. The cultivation and management of forage grass is also simpler and more labor-saving than the cultivation of grain crops, and the planting of pastures and the implementation of pasture and animal husbandry can enable the use of resources on the spot and can reduce transportation costs.
Artificial grass is a new industry. The development of artificial grass in rural areas must be synchronized with grass and livestock, promote farming with animal husbandry, and promote animal husbandry, farming and animal husbandry.
